Abstract

A device and method of visually confirming at a work site the accuracy of measurements representing the shape of an object such as a pool for the creation of a form fitted pool cover. The device includes a microprocessor for inputting a plurality of measurements representing a plurality of reference points corresponding to the shape of the object. The device further stores the measurements in the microprocessor. The microprocessor processes the inputted measurements and individually displays on the monitor reference points corresponding to the measurements inputted. This allows for the visual confirmation as to the accuracy of each of the measurements by providing the ability to compare the image displayed on the monitor with the shape of the object.

Description

BACKGROUND OF THE INVENTION

The invention relates to a portable device and method for compiling and storing data relating to the dimensional measurements of an object that are then later used to reproduced the shape of the object at an off-site manufacturing facility. Visual verification of the accuracy of the measurement data is provided at the work site so as to minimize costly measurement related errors. The device may be used with two and three dimensional objects.

SUMMARY OF THE INVENTION

The invention relates to a method and device for accurately taking measurements corresponding to the shape or an object and which are later used to recreate the object's shape at a remote location. Virtually error free measurement data is obtained by providing on-site visual verification of the measurement data taken. The device includes a portable microprocessor in which measurement data is inputted via a keyboard. The microprocessor includes software for receiving, storing and processing the inputted data and a monitor for visually displaying the shape represented by the inputted data. By visually representing the shape defined by the data inputted at the job-site, an operator may visually confirm that the shape shown on the monitor corresponds to the shape measured. Providing visual confirmation at the job-site allows an operator to correct any incorrect measurements prior to leaving the site.

DESCRIPTION OF A PREFERRED EMBODIMENT

Prior to the development of the present invention, two-dimensional objects such as pool covers and the like were measured and manufactured in an extremely inefficient manner. To create a pool cover, an operator would first need to travel to the work-site and manually perform the tedious task of recording on paper the line measurements of the pool's shape. The measurements taken typically consisted of a series of measured distances from two spaced apart reference points that were then later used to create a cover corresponding to the shape of the pool at a manufacturing facility. Often, to record the measurements needed for a contoured pool cover, upwards of 100 individual measurements needed to be accurately taken and accurately recorded. Then, at the off-site location, the measurements needed to be accurately inputted. A single incorrect measurement or input at any stage of the process will produce an incorrect match between the object manufactured and the desired shape.
The current method used by the industry requires an operator to first manually record the line measurements of an object on a sheet of paper and to draw a sketch representing the shape of the object measured. The data obtained is then delivered to a manufacturing facility where the data is inputted into an Autometrics cutting machine.
The Autometrics machine, prior to production, visually displays a shape corresponding to the data inputted. If the shape shown on the display matches the hand sketch, there is no inaccuracies. If not, an operator must again travel to the work site and the entire process is repeated until the visual display matches the hand-drawn sketch.
Such procedures, when mistakes occur, are extremely costly and time-consuming. When a mistake occurs, an operator must first schedule another visit to the work site, which adds additional cost and delays production. Moreover, remeasuring at the work site still does not guarantee accurate measurements, since visual confirmation of the accuracy is only provided at the manufacturing site.
The present invention provides a device and method that allows an operator to obtain virtually error-free measurement data. While the present invention is particularly useful in the manufacture of pool covers, tarps, and the like, it also has applicability to other applications in which the shapes of two and three dimensional objects need to be recreated at a remote location.
As shown in FIGS. 1-4, the present invention achieves error-free measurement data by providing a microprocessor 10, such as a laptop computer, which is programmed to allow an operator to input the appropriate line measurements of the object's shape via a keyboard 12. The processor is further programmed to process the inputted data and to visually display the shape represented by the data on a monitor 14. The display is created on an ongoing bases as each individual reference point is inputted.
In use, an operator travels to the work site and inputs the line measurements of the object into the portable microprocessor. To assist the operator in organizing the inputted data, the microprocessor may be programmed to provide a screen frame in which inputted data may be easily organized. For example, as shown in FIG. 1, a screen display may request the operator to not only input the measurement data, but other important information such as the customer's identity and type of material to be used. As each measurement data is inputted, the inputted data is processed and used to create a reference point corresponding to the shape of the object that is displayed on the monitor. This may be done in a split-screen display. This allows the operator to determine if accurate information has been inputted for each individual measurement, and if not, allows re-measurement or input prior to repeating the procedure for the next reference point.
By visually comparing the shape on the monitor with the actual shape of the object, an operator may immediately determine at the work site whether any inaccurate measurement was obtained or inputted. For example, as shown in FIG. 2, a properly entered data set accurately displays the shape 20 of the pool cover. However, as shown in FIG. 3, an inaccurate measurement will be easily noticed by the operator since an incorrect measurement 30 is easily noticed. Prior to leaving the work site, any necessary corrections may be made until an accurate visual representation is obtained. By visually verifying the resulting shape corresponding to the inputted data, a virtually error-free method of measuring the shape of an object is obtained.
Next, the operator may then store the inputted data on a storage device such as a diskette for subsequent downloading into machinery that will be used to construct the object. This will eliminate input errors. Alternatively, the inputted data may be electronically transmitted to the manufacturing site for use.
Electronically transmitting the verified information also allows operators to not only quickly and accurately process the data necessary to reconstruct the shape of an object, it also allows the information to be used between two geographically remote points. Such a system allows a manufacturer numerous economic benefits.
Currently available software from applicant, which is sold under the A-B VERIFIER™ trademark, may be used on currently available DOS-based microprocessors. In addition, the software may be further configured to perform the necessary operations to provide an on-the-work-site price quote.
It should be understood that various changes and modifications to the preferred embodiments described would be apparent to those skilled in the art. Changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its intended advantages. It is, therefore, intended that such changes and modifications be covered by the following claims.
