Bidirectional data transfer and storage system
First Claim
1. A bi-directional data transfer and storage system for on-line communication with telephone apparatus wherein selected data from telephone apparatus is first fed to a portable random access memory which subsequently operates on demand to display said data and/or output selected stored data to external means for dialing a telephone and when desirable thereafter communicating data over a telephone channel, the improvement comprising:
- a device carried or worn by the user including a casing, said random access memory housed within said casing, said memory having a plurality of selectable memory addresses for storing respective data signals thereat, address circuitry therefor, manual address selector means on said casing coupled to said address circuitry for accessing a desired memory address, at least one optical energy input communications channel coupled to said memory for coupling externally applied alpha-numeric data and clock signals thereto for reading selected data signals into a desired address of said memory under the control of said clock signals, an internal source of clock signals and at least one optical energy output communications channel coupled to said memory and said internal source of clock signals for reading out on demand selected data signals from a desired address of said memory and coupling said data signals and said clock signals to said external means.

Abstract
A system for bidirectionally receiving and transmitting alpha-numeric digital data via electromagnetic energy coupling means operable in the frequency range extending from radio frequencies upward. More particularly, a portable random access memory unit incorporated in a device such as a wristwatch or other relatively small portable apparatus which is adapted to be programmed by means of a relatively stationary programming device e.g. a telephone handset, when placed in proximity thereto establishes at least one electromagnetic energy communication channel whereby digital data which may be, for example, a plurality of telephone numbers and other selected data are loaded into the portable memory device. Thereafter, the portable memory device is placed in proximity with a relatively static receiver device e.g. a telephone handset, whereupon at least one electromagnetic energy communication channel is established therewith and data is read out of the portable memory device to the receiver for translating said selective data externally for remote utilization such as automatically dialing a telephone or operating a lock or other control devices. Once dialing has been effected selected other data can be fed into the communication channel as well. The communication channel is adapted to carry both digital data and synchronizing clock signals.
