Primary Examiner- Robert L. Griffin Assistant Examiner.loseph A. Orsino, Jr. AtlorneyHarvey G. Lowhurst ABSTRACT: A security system and method for controlling the passage of persons and objects between two areas employs scanning means for monitoring the contents of a control space having controlled access. Prior to admitting a person to this space, the contents are examined by the scanning means to determine the presence of any objects or persons therein. After a person is admitted to the space, access thereto is secured, such as by locking all doors thereto, and the scanning of the space continues to determine whether the admitted person has brought any unauthorized objects into the space with him. An identification procedure is then carried out for the admitted person, and if his identity is satisfactorily established, another one of the access doors is unlocked to allow the person to proceed. After departure of this person and prior to admitting another person to the space, the contents of the space are again monitored to insure that the person did not remain behind in the space, that he did not leave any unauthorized objects in the space and that he did not admit another person to the space while he was obtaining ingress or egress.

Wg mw ATTORNEY APPARATUS FOR CONTROLLING THE PASSAGE OF PERSONS AND OBJECTS BETWEEN TWO AREAS UTILIZING CLOSED CIRCUIT TELEVISION This invention relates in general to security systems, and relates more particularly to such systems for controlling the passage of persons and objects between two areas. 1 There is considerable interest in and demand for security systemsto control the ingress and egress of persons and objects in many installations. The need for such systems is most obvious in connection with installations having government security requirements, such as military, atomic energy and intelligence facilities, but many nongovernment facilities desire such systems to maintain control over employees and visitors and the objects which they bring into or take out of the facility. Traditionally, such systems involved the use of one or more human guards located at openings in an otherwise enclosed area. The guards screened arriving and departing persons in any one of a number of ways, such as recognition by sight, badges, identification cards, etc., and often performed at least a cursory visual examination of departing employees to detect any misappropriation of company property. However, the use of human guards in this fashion has the distinct disadvantage of being quite expensive in terms of salaries, benefits, etc., particularly where there are a number of openings which must be simultaneously manned, many on a twenty-four hour basis. Additionally, human guards are sometimes subject to lapses of fallibility and will permit unauthorized persons or objects to pass the guard station.
Recently, a number of automatic or semiautomatic security systems have been suggested in pictorial literature and spy type motion pictures which purport to reduce or eliminate the problems involved in human control of the screening of persons and objects. Such systems suggest a number of different techniques, such as the use of a video pickup to transmit a picture of the person seeking ingress or egress to a central control where a decision is made, usually based on recognition of the person by a guard at the central control, and sometimes requiring conversations with the person.
However, none of these suggested systems disclose a satisfactory system or the means necessary to provide reliable control over the passage of persons and objects between two areas. In accordance with the present invention, there is provided methods and apparatus for security control which employ a space having a first door which communicates with one area from which persons and objects arrive seeking admission, and a second door communicating with another area, the doors and the space, of course, being the only path between the two areas. Each of the doors is provided with means for indicating the open or closed condition thereof, and means for locking and unlocking the door. The space itself is provided with sensing means for sensing or determining the presence of objects or humans therein, as well as means for examining the identity of a person therein.
Prior to use of the space, both doors are locked. A person seeking to pass through the space from one area to the other initiates a request at the appropriate door and, assuming that the space is not then in use, that door is unlocked if the other door is locked. As the person opens the unlocked door to enter, the space sensing means is preferably energized to monitor the contents of the space from that point on in the examination. After the person enters the space and closes the door behind him, that door is locked, and the identity sensing means is energized to examine the identity of the person. If the identity examination indicates that the person is suitable for passage to the other area, and if the space sensing means indicates that there are no unauthorized articles or persons in the space, such as unauthorized objects or another person in addition to the one examined, the other door is unlocked to permit the examined person to pass into the other area.
When the departing person closes the door, it is locked and the space sensing means again examines the space for the presence of any objects or persons. Such a person might be one who entered the space while the door was open for the examined persons departure, and such an object might be one which the departing person deposited therein. This is an important feature of our invention, since it prevents a personin the space from leaving behind, either intentionally or unintentionally, some object which could be picked up by a person subsequently entering the space. If the space sensing means does detect an object or person remaining in the space,'the system is preferably prevented from conducting any further examination until suitable corrective action has been taken. If the space sensing means does not detect any object or person remaining in the space, the system is ready for the next person arriving at either door seeking passage through the space.
In one form of the present invention, the space sensing means includes a first video pickup disposed in the space so as to provide at a remote control console an overhead view of the space. This overhead view facilitates the detection of unauthorized objects or persons in the space compared with a conventional system which would provide a view from the side of the space. The overhead view is particularly effective in detecting irregularities such as objects or persons disposed on the floor of the space, or a person hiding behind the person being examined in the space. The identity examining means includes the above described video pickup and a second pickup which is positioned to scan a photograph on an identification card presented by the person being examined. Through a unique optical system, the first video pickup is switched during the identity examining procedure from the overhead view it provided during the space sensing operation to a view of the face of the person'presenting the identification card. The video pictures of the photograph on the card and the face of the card bearer are transmitted and displayed simultaneously at the control console for comparison. If the pictures correspond, the persons identity is satisfactorily established and he is allowed to proceed. If the pictures do not correspond, suitable action is taken, such as permitting the person to leave the space through the door by which he'entered, or keeping the person locked in the space to detain him for further examination or other action.
It is therefore an object of this invention to provide a security system for controlling the passage of persons and objects through a closed space from one area to another, in which the space is examined prior to the admission of a person thereto to detect the presence of unauthorized objects or persons therein, and after admission of a person to the space, the space is sealed off and the person examined as to identity.
It is a further object of this invention to provide a method for controlling the passage of persons and objects through a closed space between one area and another, which involves examining the space for unauthorized objects or persons prior to admitting a person thereto, admitting the person, sealing off the person in the space, examining the person in the space as to identity, and permitting the person to pass through the space if his identity is satisfactorily established by the examination.
It is an additional object of the present invention to provide a method for controlling the passage of persons and objects through a closed space between one area and .another, which involves the steps of examining the space for unauthorized objects or persons prior to admitting a person to the space, admitting the person, locking the person in the space, examining the person in the space as to his identity, permitting the person to pass through the space if his identity is satisfactorily established by the examination, locking the space after the departure of the examined person, and again examining the space for unauthorized objects or persons.
It is an additional object of this invention to provide a security system employing a first video pickup to transmit a picture of the interior of an examining space to detect unauthorized objects or persons therein, and employing a second video pickup to transmit a picture of a photograph on an identification card presented by a person being examined in the space while the first pickup is transmitting a picture of the face of the person presenting the card, a comparison of the transmitted pictures resulting in a decision as to the suitablity of the person to proceed through the space.
It is a further object of this invention to provide an improved security system for controlling the passage of persons and objects between one area and another, which system employs an enclosable space between the areas which can be examined as to contents before, during and after the passage of a person therethrough and in which the identity of the person can be examined.
Further objects and advantages of the present invention will become apparent to those skilled in the art to which the invention pertains as the ensuing description proceeds.
The features of novelty that are considered characteristic of this invention are set forth with particularity in the appended claims. The operation of the invention itself will best be understood from the following description when read in connection with the accompanying drawings, in which:
FIG. 1 is a schematic diagram of one embodiment of the present invention which is essentially fully automatic;
FIG. 2 is a perspective view of a booth forming the examining space in one embodiment of the present invention, together with a control and indicating unit used in connection with one or more of these booths;
FIG. 3 is a side view of the booth of FIG. 2 showing one embodiment of the space sensing and identity examining means; and
FIG. 4 is an overhead view of the booth of FIG. 2, showing further details of the space sensing and identity examining means.
Referring to FIG. 1, a security system according to this invention is shown which is essentially fully automatic.
'Reference character 11 designates the enclosable space through which persons and objects must pass in going from one area to another. Space 11 may be, for example, a booth having doors 12 and 13 on opposite sides thereof leading to the areas which are to be controlled, with space 11 being the only path between the two areas. Each of doors l2 and 13 is provided with means for sensing and indicating the open or closed condition of the door, as well as means for locking and unlocking the doors. Such means are shown schematically as a door sensor 16 associated with door 12 and having one output line 16a indicating that the door is open and another output line 16b indicating that the door is closed. Similarly, door 13 has a door sensor 17 having an output line 17a indicating that the door is open and a line 1711 indicating that the door is closed.
The door locking and unlocking means is shown schematically as a door lock means 18 for door 12 having one input line 18a which, when energized, unlocks door 12, and another input line 18!) whose energization results in locking of door 12. Similarly, a door lock 19 is provided for door 13 which has an unlocking input line 19a and a locking input line 19b. Door locks 18 and 19 may be any suitable well-known type which can be controlled to lock and unlock the associated doors upon energization of the appropriate input lines.
Space 11 is also provided with space sensing means, shown schematically at 21, for detecting the presence of objects and persons within the booth. Sensing means may be constructed to sense the number of objects (including persons) occupying the booth or the absence thereof. Sensing means 21 has an input energizing line 21a and a pair of output lines 211; and 210. Output line 21b is energized when the sensing means 21 indicates that the booth is properly occupied, such as for example by a single person, and line 21c is energized when the sensing means detects that the booth is improperly occupied, such as for example by more than one person, or a person and an object. In any case, sensing means 21 is programmed in accordance'with a'selected set of conditions to indicate whether the selected set of conditions is met or is not met. Sensing means 21 may be any suitable type of means capable of monitoring the contents of space 11. One example of such sensing means would be a video pickup which transmits an image of the interior of the booth to a control monitor. Another example is a thermal energy detector capable of detecting heat or moisture from persons in space 11 and providing output indications according to the energy detected. Other sensing means might utilize the measurement of the absorption of acoustic or electromagnetic energy by persons or objects in the space 11 to provide an indication of its contents.
Where a video pickup is employed as the sensing means in space 11, the signal therefrom is transmitted to a central control for examination by a human operator, who will take some action in accordance with the nature of the information received and actuate either line 21b or line 21c depending on whether visual inspection shows that the selected set of condi tions is met or is not met. However, it is possible to have a fully automatic system which does not require human intervention where other types of sensing means are employed that are capable of generating the proper control signals in dependence upon the objects or persons detected in space 11. 7
Space 11 is also provided with an identity examining means, shown schematically at 22, for examining the identity of the person in the space and determining his suitability to enter the area to which he is seeking access. Such identity examining means may be of any suitable type, such as a video pickup for simultaneously transmitting pictures of the face of the person in the space and the photograph on an identification card which that person is carrying. In this situation, the pictures would be transmitted to the central control for examination by a human operator, and if the pictures corresponded (and if the person was otherwise suitable), the operator would take the appropriate action to allow the person to proceed.
Other identity examining techniques may be employed, such as matching the persons fingerprints against a master file of fingerprints of authorized people, or matching the persons voice, by means of voice recognition equipment, against a master file of voices of authorized people. Again, these latter two techniques would be capable of fully automatic operation without human intervention.
Identity examining means 22 is provided with an energizing input line 22a, an output line 22b indicating that the identity of the examined person is not satisfactory. in this connection, it will be noted that it is not necessary to the operation of this system that the person be examined positively; it is sufficient if information is provided as to the suitability or nonsuitability of the person.
The operation of the remainder of the system of FIG. 1 can best be understood by considering its action in a typical situation. Assume that a person approaches door 12 and desires to pass through space 11 and door 13 to the other area. The per son would initiate an entry request through an entry request device 26 which is located adjacent door 12 and which may be a pushbutton switch which produces an output on a line 260 when actuated. A similar entry request device 27 is located adjacent door 13 and has an output line 27a. The signals on lines 26a, 27a are supplied as inputs to respective AND gates 29, 30 which also receive inputs from a busy gate 33. Gate 33 has a not busy" output line 33a which indicates that the system is not busy examining another person and which is supplied as an input to gates 29, 30. Gate 33 also has a busy" output line 3312 which may be utilized to provide an indication to the person requesting entry that the system is in use, and which may also be supplied to a central control station to indicate that that particular booth is in use.
For tie-breaking purposes, to prevent simultaneous system response to simultaneous actuation of both entry request devices, output lines 29a, 30a of gates 29, 30 pass through a network 28 designated as an exclusive OR gate which permits only one signal to pass therethrough at a time. Output lines 28a, 28b of gate 28 are supplied as inputs to busy gate 33, and the presence of a signal on either of these lines is effective to raise the busy line 33b and deenergize the not busy" line 33a. Gate 33 is also supplied with a reset line 33c which is energized at the end of the examining procedure in a manner to be described below, to reset the gate to the not busy condition.
I The output lines 28a, 28b from network 28 are also connected to the respective inputs of AND gates 31 and 32. AND gate 31 receives another input from the door closed line 17b of door sensor 17 associated with door 13. Thus, if door 13 is closed, the output on line 17b, coupled with the entry request signal on line 28a, actuates gate 31 to energize the unlocking line 18a of door lock 18 on door 12. Door 12 is thereupon unlocked and the person seeking admission presumably opens the door. When door 12 is opened, the signal produced on the door open" line 16a of door sensor 16 issupplied to means 36 for energizing space sensor 21. The other input to means 36 is supplied from the door open line 17a of door sensor 17. Space sensor 21 is thus energized upon opening of either of doors 12, 13 to monitor the contents of space 11 from that time forward in the examination procedure. This is an important feature of the present invention, since it assures monitoring of the space contents during the interval between the door opening and the initiation of the identity examining procedure, and would detect such irregularities as more than one person entering the space or the insertion of unauthorized objects into the space.
The output of AND gate 31, which energized the door unlocking line 18a, also passes through a time delay device 38 to an AND gate 39. The other input to gate 39 is supplied from the door closed" line 16b of door sensor 16. A similar time delay device 41 and AND gate 42 are provided for door 13, gate 42 receiving its other input from door closed" line 17b of door sensor 17. The time delay of delay devices 38, 41 is selected to allow the person sufficient time to open the door after it was unlocked, enter the space and close the door behind him. Assuming that this has occurred, as evidenced by a signal on door closed line 16b, gate 39 is energized to supply a signal on line 18b to door lock 18 to lock door 12. The door locking signals produced by gates 31, 32 are also supplied through an OR gate 35 to means 37 for energizing the identity sensing means 22. Identity sensing means is thus energized upon the locking of either door 12, 13. The door locking signals are also supplied from OR gate 35 to a counter 43 which produces an output signal on a line 43a after two door locking signals have been received. This output is supplied through a time delay device 44 to a reset generator 45 which produces a resetting signal, in a manner to be described below.
At this point, both doors to the space are locked and the person initiating the entry request is presumably in the space awaiting the identity examination. If such is the case, the identity examination begins, either by video transmission of the face of the person and the photograph on his identification card, or the matching of his fingerprints or voice against those in a master file as discussed above, or in any other appropriate manner which will establish the suitability of that person to proceed. identity sensor 22 is preferably of the type which produces an output signal upon completion of the identity examination, indicating either that the identity is satisfactory (line 22b) or that it is unsatisfactory (line 220).
If the identity is satisfactory, the resulting signal on line 22b is supplied as one input to an AND gate 45. Gate also receives an input from the satisfactory" line 21b of space sensor 21. The output from space sensor 21 is preferably a continuous one which continuously indicates the satisfactory or unsatisfactory condition of the contents of space 11. That is, if an unauthorized person or object is present in space 11, the unsatisfactory line 210 would be energized as long as this condition prevailed; when the condition was removed, such as by removal of the unauthorized object or departure of the unauthorized person, line 210 would be deenergized and satisfactory" line 21b would be energized.
Assuming the space sensor output indicates a satisfactory condition if identity sensor 22 produces a satisfactory output on line 22b, gate 45 is energized to produce an output signal which is supplied as one input to a pair of AND gates 47, 48. The other inputs to gates 47, 48 are supplied from a pair of latches 49, 51 which form a memory circuit for remembering which door initiated the entry request. Latch 49 is connected to entry request line 28b and is latched up in response to a signal on that line. Once latched, the latches remain in that condition until reset by their respective reset lines.
in the example operation under discussion, the initial entry request at door 12 will have latched up latch 49 to provide one input to gate 47. Thus, when the satisfactory" signal from gate 45 is supplied to gate 47, this later gate is energized to supply a signal over its output line 47a to the one input of unlocking gate 32. The other input to gate 32 is supplied from the door closed" line 16b for door 12, and assuming that this door is closed, gate 32 is energized to supply a signal on line 19a to unlock door 13. This permits the person in the space to open door 13 and enter that area, his identity having been satisfactorily established. After the time delay of device 41, and if the departing person has closed door 13, gate 42 is energized to lock door l3 through line 19b.
This locking causes counter 43 to produce an output signal on line 43a, and this signal passes through time delay device 44. The delay of device 44 is selected to permit space sensor 21 sufficient time to examine space 11 to detect the presence of any unauthorized objects or persons. Since the examined person has presumably left space 11 through door 13, there should be no object or person in the space at this time, and sensor 21 examines the space to determine that this condition in fact prevails.
If the person examined has actually left space 11, and has not permitted another person to enter the space through door 13 while he was departing, and has not left any material in the space, space sensor produces a satisfactory output on line 21b. After the delay of device 44 expires, the output signal from reset generator 45 is supplied as a resetting pulse to busy gate 33, to latches 49, 51, to energize network 37 for identity sensor 22 and to energize network 36 for space sensor 21. Identity sensor 22 and space sensor 21 are thus deenergized and the system is returned to the condition to await another entry request.
This completes what might be termed a normal procedure, with an authorized person entering space 11 with no unauthorized objects with him, having his identity established as satisfactory by identity sensing means 22, and then leaving space 11 to enter the other area, properly closing each door behind him. It will be appreciated that there will be some situations in which either the identity of the person is riot satisfactorily established or space sensor 21 indicates the presence in space 11 of unauthorized objects or persons. Under these circumstances, there are a large number of different control actions which can be performed in response to other than normal conditions. For example, in the case of unsatisfactory identification by identity sensor 22, the simplest control action would be to unlock the door by which the person entered the booth, permitting the person to return to the area from whence he came but not allowing him access to the other area.
The system shown in FIG. 1 has'the capability to provide this action in response to the appearance of a signal on the unsatisfactory output line 220 of identity sensor 22. The signal on this line is supplied as an input to two AND gates 56 and 57, and each of these gates receives another input from latches 49, 51 associated with the entry request devices 26, 2'7. Assume in the example above that the person entering space 11 through door 12 had not satisfactorily established his identity and identity sensor 22 produces an'output on unsatisfactory line 22c. This signal is supplied to gates 56, 57 and since gate 56 has another input thereon from the latch 49 which was set in response to the persons entry request, gate 56 is energized to produce an output on line 56a.
This signal is supplied to the input of gate 31 which controls the unlocking of door 12, and assuming that the other input is present at gate 31 indicating that door 13 is closed, gate 31 is energized to unlock door 12 over line 18b. This permits the person in space 11 to open door 12 and return to the area from which he came. This unlocking may be accompanied by an audio message or the like informing the person that his identity has not been satisfactorily established and advising him to leave the booth by the door he entered and proceed to another area for further efforts at identification or other procedures.
After the time delay of device 38, door 12 is locked again through a signal on line 18b. Space sensor continues to monitor the contents of space 11 to detect any unauthorized objects or persons, such as an objectleft behind by the person whose identity was not satisfactorily established, or a person who entered space 11 when door 12 was unlocked to permit the examined persons departure, or the failure of the examined person to leave the space.
Assuming that no such unauthorized object or person is detected, after the delay of device 44 has elapsed, space sensor 21 is deenergized, latches 49, 51 are reset, and gate 33 is reset to provide a not busy" signal, thus readying the system for another person to be examined.
In some instances it may be desirable to take some action in response to an unsatisfactory identification other than permitting the person to return through the door by which he entered space 11. For example, it may be desirable to detain the person for further investigation. This type of action can be provided by locking both doors l2, 13 in response to an unsatisfactory identification, as indicated by the dotted line 22d which is connected from line 22c to the locking inputs 18b, 19b of door locks 18, 19. This action would detain the person in space 11 until he could be removed for questioning or other action.
The unsatisfactory output line of space sensor 21 may also be connected to line 22d to provide this locking action if desired under certain circumstances, such as the detection of another person in the booth in addition to the one whose identity is being examined, or the detection of some types of unauthorized objects in the booth. Additionally, suitable alarm means may be energized by either or both of the unsatisfactory output lines of sensors 21, 22 to provide an alarm signal which may be employed as a supplement to the other control or corrective actions.
Referring now to FIGS. 2, 3 and 4, in which like reference characters are used to designate like parts, there is shown a booth 11 which forms the examining space for controlling the passage of persons and objects between two areas. Booth 11 is surrounded by fencing as shown so as to be the only passage between the areas on either side of the fencing, and may be one of a number of similar booths in a complete installation.
Booth 11 is provided with doors 12, 13 which provide access, and is also provided with entry request devices, such as the push button 26a mounted adjacent door 12 as shown in FIG. 2. A busy indicator 33b may also be provided adjacent button 26a to indicate to a prospective entrant that the booth IS in use.
Booth 11 employs a video pickup device 71 as part of the space sensor 21, and this pickup is mounted in the booth so as to permit maximum examination of the booth contents for the presence of unauthorized objects or persons. As best shown in FIG. 3, pickup 71 is mounted adjacent the ceiling of booth 11 and is separated from the person 66 to be examined by a transparent partition 11b.
The optical path for pickup 71 includes a first mirror 72 which is movable between two positions. In the position shown in solid lines in FIG. 3, mirror 72 reflects light into pickup 71 from a second mirror 73 mounted near the top of booth 11. Mirror 73 is preferably of a size which will provide a view of the entire booth area, as shown. Pickup 71 thus effectively sees the entire booth from an overhead view as shown in FIG. 3. This greatly facilitates examination of the booths contents to detect unauthorized objects and persons therein, such as a person crouching in the booth or a person hiding behind the person 66 being examined.
The video signal from pickup 71 is transmitted by suitable means, such as cabling 75 (FIG. 2) to a cathode ray tube 76 for display. Tube 76 may be part of a control and monitoring console 77 disposed at a central control location. In this situation, tube 76 is monitored by a human operator and certain control actions taken in response to the information presented on the screen of the tube.
Booth 11 is also provided with identity examining means which may include a second video pickup 81 mounted behind partition 11b. In the embodiment shown, it is assumed that each person to be examined is carrying an identification card 82 which bears a photograph of the card owner. Pickup 81 transmits a picture of this photograph for comparison with the face of the person presenting the card. Card 82 is inserted in a slot 110 (FIG. 3) which properly positions the card for scanning by pickup 81 through a mirror 83. The signal from pickup 81 is transmitted through cabling 75 to a second cathode ray tube 86 mounted in console 77.
Simultaneously with this transmission and display of the photograph on card 82, a picture of the face of the card bearer 66 is presented on tube 76 from pickup 71. For this operation, mirror 72 swings up out of the path of pickup 71'to the position shown in dotted lines in FIG. 3. A mirror 87 is positioned as shown to reflect the face of card bearer 66 into pickup 71. The pictures of the photograph on card 82 and the face of its bearer are thus simultaneously displayed on a side by side basis on the faces of tubes 76, 86 of console 77. By suitable choice of the optics involved, the two pictures on tubes 86, 76 can be on approximately the same scale to facilitate their comparison for identity.
Console 77, in addition to tubes 76, 86, may also be provided with switches 88, 89 for controlling the locking and unlocking of doors 12, 13, respectively. Switches 88, 89 are interlocked so as to prevent unlocking of one door unless the other door is locked, as has been described above in connection with the description of FIG. 1. Console 77 is also provided with indicator lights 91, 92 which are connected to the door sensors (not shown) to provide an indication of the open or closed condition of each of doors l2, l3. Console 77 may also have indicator lights 94, indicating the presence of entry requests at the different doors of booth 11. A microphone 93 may also be provided for transmission of audio messages to booth 11 for interrogation or the like.
In the operation of the system shown in FIGS. 24, both doors of booth 11 are locked when not in use. A person arriving at a door seeking entrance pushes the entry request button, and if the booth is not already in use, this action lights an indicator light 94 or 95 on the console 77 at the control station. The console operator, in response to this entry request indication, actuates the appropriate one of switches 88, 89 to unlock the proper door. As soon' as the person opens the unlocked door, pickup 71 is energized to monitor the booth from an overhead view, as described above in connection with FIG. 1, and present on tube 76 a picture of the activity in the booth. As indicated above, this is an important feature of this invention, since it permits the console operator to observe the booth and the conduct of the person entering it from the time the door is opened.
After the person enters the booth and closes the door behind him, the door is locked. The console operator may then initiate the identity examining procedure by switching pickup 71 from the overhead view to the face-examining view by actuating suitable switching which causes mirror 72 to retract to the position shown in dotted lines in FIG. 3. This action would also energize pickup 81. The person 66 then presents the identification card in slot 110, and video pictures of the photograph on this card and the face of the card bearer are simultaneously presented on the faces of tubes 76, 86. The operator examines these pictures, and if satisfied of the correspondence, actuates one of switches 88, 89 to unlock the other door for the departure of the examined person. At this point, the operator preferably switches pickup 71 back to the overhead view condition to monitor the booth during the persons departure to detect any irregularities such as another person entering the booth while the examined person departs, or the leaving of an object in the booth by either the departing person or another person outside the open door.
After the examined person closes the door, this door is locked by the operator actuating the proper switch. The operator continues to monitor the booth contents with the overhead view of pickup 71 after this door locking to insure that no irregularities have occurred. If this monitoring indicates a satisfactory condition in the booth, it is ready to receive another person for examination.
It will be appreciated that the embodiment shown in FIGS. 24 offers a great deal more flexibility than that of FIG. 1 in practicing the present invention by virtue of the ability of the human console operator to make decisions based on the information presented to him on tubes 76, 86. The automatic system of FIG. 1 has the advantage of not requiring the expense of human operators for normal operation, but it does not have the ability, with the elements shown in FIG. 1, to handle out-of-the-ordinary situations which a human operator can easily accommodate. For example, it is quite probable in many high activity locations that when an examined person opens the booth door to proceed to the other area, a person waiting at that door for admittance to the booth may enter the booth to be examined. This situation would be difficult to accommodate with the system in FIG. 1, because of the relatively simple level of logic provided, but it could be easily handled by a human operator at console 77 who could observe the situation through pickup 71 and take the necessary steps to examine the newly admitted person.
However, whether the invention is practiced with a system such as shown in FIG. 1, or with a less automatic system as shown in FIGS. 2-4, it will be seen that the invention provides novel methods and apparatus for controlling the passage of objects and persons from one area to another.
There has been described a method and an apparatus for controlling the passage of persons through a closed space between two areas in which .the space is examined prior to admission of persons, after the admission of persons and after the admitted person has departed. Further, the person, after being admitted into the closed space, is held there for identification and is only passed through into the'other area after having been found acceptable.
While the above detailed description has shown, described and pointed out the fundamental novel features of the invention as applied to various embodiments, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated-may be made by those skilled in the art, without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claims.
1. Apparatus for controlling the passage of persons and objects through a passageway leading into a secured area comprising:
an enclosure means having an examination compartment large enough to accommodate a single person in a standing position for disposition in said passageway and having a first lockable door and a second lockable door providing an entrance and an exit respectively, to said compartment, said enclosure means blocking said passageway except when said lockable doors are open;
first sensing means for examining the contents of said compartment from at least two orthogonal directions to determine the presence of a person or object therein, said first sensing means being a first video scanner means for alternatively providing a vertical overhead view of substantially the entire interior of said examination compartment and a horizontal view of said compartment;
means for remotely opening one of said doors and for energizing said first sensing means;
second sensing means for examining a characteristic of a person in said enclosure means to determine that persons suitability to proceed through said enclosure means, said second sensing means including a second video scanner means which scans a photograph on an identification card carried by said person while said first video scanner means scans the face of said person during said horizontal view; and
means responsive to said sensing means for determining the suitability of said person to proceed through said enclosure means and for unlocking the other of said doors to permit said person to proceed therethrough if said examined characteristic indicates his suitability to proceed, said means responsive to said sensing means including a means for comparing the images produced by said first and second scanner means to determine correspondence therebetween as a measure of said persons suitability to proceed through said enclosure means.
2. Apparatus in accordance with claim 1 including movable mirror means having a first position for reflecting an overhead view of the interior of said enclosure means to said first video scanner means for examining the contents of said enclosure means, and having a second position for permitting an image of said persons face to be transmitted to said first video scanner means.
