Description

Charger and/or power device for wireless electrical devices or batteries thereof
The present invention relates to portable electrical devices, which are generally called PDA (Personal Digital Assistant), such as mobile communication devices, portable computers and portable CD (Compact Disc), DND (Digital Versatile Disc), MD (Mini Disc), MP3 (MPEG-1 Audio Layer-3) players, portable terminals which enable Internet connection, etc. In more detail, the object of the present invention is a charger and/or power device for portable PDA (Personal Digital Assistant) devices or batteries thereof, according to the preamble section of Claim 1.
The problem with such already known devices is their inconvenient usability. Typically, charging of device batteries requires carrying a charging device, and plugging this charging device into a socket connected to mains current. With charging devices, one must typically carry a transformer or a switched-mode power supply which is needed for transforming mains current to weak current and is typically located inside the casing of the charging device. This structure typically makes charging devices extremely heavy and typically large. Furthermore, the charging devices of PDA devices must be either 1) equipped with a long cable, in order to plug them into mains current sockets, which are, when indoors, typically situated in walls near floor level, and, on the other hand, to be connected into the wireless electrical device, or 2) wireless terminals have to be plugged into a so-called desktop charger, in which the use of a wireless terminal is typically either impossible or inconvenient.
Because of safety problems, mains current wall sockets cannot be situated, for example, on restaurant tables. Furthermore, plugging charger device cables into mains current wall sockets near floor level may cause a situation in which a charger cable is left on the floor, and a person trips over the charger cable. Typically, the problem with the charger devices of portable wireless terminals is also that the long charger cable gets entangled while carrying the charger device in a bag.
Typically, the already known devices also lack the possibility to update the device characteristics so that they would be suitable for devices demanding different volt or ampere amounts other than they were originally intended to.
The object of the present invention is to eliminate, or at least essentially decrease, defects related to already known charger and power devices, and to produce a new charger and power device for charging wireless PDA device batteries and for power supply of wireless terminals, with which one can in a versatile, effective and user- friendly manner charge the batteries of wireless terminals and/or use a new method and device as the source of power for wireless terminals.
This object has been accomplished by means of the charging and power device mentioned at the beginning, the specific characteristics of which are presented in the appended array of claims.
Thus, it is predominantly a characteristic of the charger and power device according to the invention that the charging and/or power cable device comprises a charging and/or power cable reel, from which a charging and/or power cable can be taken out, and into which it is coiled or can be coiled, and that the charger and/or power supply station supplies charge and/or supply current through the charging and/or power cable to the PDA device when the charging and/or power cable device is docked into the docking unit. It is advantageous according to a recommended embodiment of the invention that the charging and/or power cable device is further secured to operate with the charger and/or power supply station as a charger and/or power device which supplies charge and/or supply current, with the help of at least one memory unit and a processor device reading it. Advantageously the processor device, such as a microprocessor, is arranged into the charger and/or power supply station, and the memory unit, such as a ROM (Read-Only Memory) or for example an EPROM (Erasable Programmable Read-Only Memory) or a PROM (Programmable Readonly Memory) or a microchip (CHIP) or a logic array for the processor, is arranged into a chargmg and/or power cable device.
Such following advantages of the invention could be mentioned that the charging and/or power cable can be effectively protected from mechanical wear and chafing, as the charging and/or power cable, in which there is a PDA device connector, can be coiled, for example with a lever, or coils, for example spring-loadedly, into the protection of the casing of the charging and/or power cable device. The result of this protective coiling/being coiled is also that it may effectively prevent the fact that the charging and/or power cable gets entangled, for example, while carrying the charging and/or power cable device in a bag etc. Another advantage of such charging and/or power cable device is that it needs no transformer or switched-mode power supply, so the charging and/or power cable device can be manufactured much more lightweight than already known charger and power devices, which are equipped with a transformer or switched-mode power supply. A possibility must still be stated on the charging and/or power cable device that the casing of the charging and/or power cable device can be equipped with a holder with which the charging and/or power cable device can be carried on, for example, a belt.
According to the advantageous embodiment of the invention, the charger and/or power supply station of the charger and/or power supply device may be safely located into the best possible place from a the point of view of availability, because, in the recommended embodiment of the invention, no other than weak current is supplied into the charger and/or power supply station, and because the charger and/or power supply station identifies the charger and power cable devices and conducts current into no other than approvedly identified charger and power supply devices. Thus, in order to use the charger and power device in charging the PDA device batteries and/or as PDA device power supplies, they can be located indoors separately from each other in easily accessible places, such as tables, working surfaces, walls or separate and independent stands. The produced charger and power stations enable the charging of PDA device batteries and/or the use of a wireless terminal with the weak current received from the charger unit, when the separate and, for example, portable charging and/or power cable device, which comprises a cable reel and an electronic memory unit, is docked into the charger and/or power supply station functioning as a power supply, and as the cable which can be taken out of the cable reel is connected with its connector to the connector intended for charging of PDA device batteries and/or power supply.
The invention will now be explained in more detail, by way of a certain advantageous embodiment, with reference to the accompanying drawings, in which FIG. la. diagrammatically illustrates a charger and/or power device, according to the invention, which is not connected to mains current or a PDA device, and, furthenriore, the charging and/or power cable device is separate from the charger and/or power supply station,
FIG. lb diagrammatically illustrates a charger and/or power device, according to the invention, which is connected both to mains current and a PDA device, and, furthermore, the charging and/or power cable device is set or docked to the charger and/or power supply station, and
FIG. 2 illustrates an advantageous prototype of the invention in a perspective view.
Referring to Figures la and lb, in which a charger and/or power device for portable PDA (Personal Digital Assistant) devices 1 or batteries thereof according to the invention is illustrated. The charger and/or power device comprises a charger and/or power supply station 3, connected through or with the help of a switched-mode power supply 2. This device is equipped with at least one docking unit (4, see Figure 2) to receive a charging and/or power cable device 5, in which charger and/or power supply cable comprises a power cable 51, in the clear end of which there is a charger and/or power supply plug 52 suitable for the charger and/or power supply connector 11 of the PDA device 1.
It is advantageous to the charging and/or power cable device 5 of the charger and/or power device according to an advantageous embodiment of the invention that it comprises a charging and/or power cable reel 55, from which can be pulled out and into which coils or can be coiled a charging and/or power cable 51, and that after the charging and/or power cable device 5 is, according to Figure lb, set or docked to the charger and/or power supply station 3, it will function as a charger and/or power device supplying charge and/or supply current.
It is recommended that the operation and compatibility of the charger and/or power supply station 3 and the chargmg and/or power cable device 5 are further secured with a memory unit 53 fitted into the charging and/or power cable device 5 and a processor device 31 which reads memory unit 53 and is fitted into the charger and/or power supply station 3. To produce such a combination of the memory unit 53 and processor device 31 it is advantageous according to the invention that the memory unit 53 of the charging and/or power cable device 5 is a ROM (Read Only Memory) memory, and that the processor device 31 of the charger and/or power supply station 3 is a microprocessor integrated into the electronics circuit of the charger and/or power supply station 3.
Referring to Figure 2. According to the invention, the memory unit 53 and the processor device 31 are in data transmission contact with each other, when the contact surfaces or parts (not illustrated in the figures) of the charging and/or power cable device 5, of which the prototype illustrated in Figure 2 accommodates two pieces, are against the contact surfaces or parts 41 of at least one of the docking units 4 of the charger and/or power supply station 3. In the prototype according to Figure 2, there are two docking units 4. To produce contact surfaces or parts it is advantageous according to the invention that the contact surfaces and parts in the charging and/or power cable device 5, for example, contact pins, are designed so that they will automatically set against the contact surfaces or parts 41, such as contact pins, in the docking unit 4 of the charger and/or power supply station 3, when the charging and/or power cable device 5 is set or docked to the charger and/or power supply station 3. Correspondingly, the contact pins 41 in the docking unit 4 of the charger and/or power supply station 3 are designed so that they will automatically settle against the contact pins in the chargmg and/or power cable device 5, when the charging and/or power cable device 5 is set or docked in the charger and/or power supply station 3. Then, it is advisable that at least the contact pins 41 in the docking unit 4 are, for example, spring-loaded.
When the charging and/or power cable device 5 according to the present invention is docked into the charger and/or power supply station 3 according to Figures lb or 2, the electronics of the charger and/or power supply station 3, which comprise the above mentioned processor device (31, see Figure la), identify the docked charging and/or power cable device 5, and determines, according to the data or other control information received by the charging and/or power cable device from electronic memory unit (53, see Figure la), the chargmg and/or power cable device 5 in question, and further through this the direct current voltage [N] and amperage [A] to be supplied for the PDA device.
The electronic memory unit 53 in the charging and/or power cable device 5, which is illustrated in Figures la and lb with dashed line, comprises either an encryption algorithm or programme, which sends an encryption identifier or a serial number, because of which the microprocessor 31 of the charger and/or power supply station 3 only reacts to such a charging and/or power cable device 5 which gives an acceptable encryption identifier or serial number or an encryption identifier or a serial number which belongs to the set of encryption identifiers or serial numbers determined beforehand. Because in the electronics of the charger and/or power supply station 3, advantageously in the processor device 31, which is illustrated in Figures la and lb with dashed line, comprise an identification based on either the encryption identifier or serial number given by the memory unit 53, and the charger and/or power supply station 3 reacts to no other than a charging and/or power cable device 5 which gives an acceptable encryption identifier or serial number, the charger and/or power device according to the invention is formed until after an acknowledged identification.
It is especially advantageous that the electronic memory unit 53 of the charging and/or power cable device 5 may be replaced or updated so that it will be suitable for the demands of different PDA devices 1 on the ampere amounts and voltages of supplied current.
