Abstract

A wireless caller identification system employing master and remote units. Microcontrollers at both master and remote units facilitate secure communications between units, providing the identity of the source of calls received at the master unit over a connected telephone line from a telephone central office. Radio frequency (RF) or infrared (IR) modes of communication may be used.

Claims

1. A wireless caller information processing system comprising:

at least one master unit, including wireless transmission means, connected to a telephone central office via a central office telephone line;

at least one remote unit, including wireless receiving means and display means connected to said wireless receiving means;

said remote unit located within wireless communication range of said master unit;

said master unit in response to receipt of signals representative of the identity of the source of an incoming call received over said telephone line at said master unit, to operate said wireless transmission means to transmit said identity signals to said remote unit;

said remote unit in response to receipt of said identity signals by said wireless receiving means to operate said display means to provide a visual indication at said remote unit of the identity of said source of the incoming call received at said master unit;

said master unit including a decoder connected to a microcontroller with a line interface connected between said central office telephone line and said decoder, said decoder operated in response to receipt of said identity signals to said line interface from said central office telephone line, to convert said identity signals from a first code to a second code, and further operated to transmit said identity signals in said second code to said microcontroller.

2. A wireless caller information processing system as claimed in claim 1 wherein:

said decoder converts said identity signals from a frequency shift keying code to an ASCII code.

3. A wireless caller information processing system as claimed in claim 1 wherein:

said microcontroller includes identification code means and memory means;

said memory means operated to store unique identification code from said unique identification code means and said identity signals in said second code.

4. A wireless caller information processing system as claimed in claim 1 wherein:

there is further included wireless receiving means connected to said microcontroller operated in response to receipt of signals representative of the identity of said remote unit to further operate said microcontroller to operate said wireless transmission means to transmit said identity signals to said remote unit.

5. A wireless caller information processing system as claimed in claim 1 wherein:

there is further included display means and a key pad, both including circuit connections to said microcontroller;

said display operated in response to information stored in said microcontroller memory to provide a visual indication of information stored in said memory;

and said key pad manually operated to input information into said memory included in said microcontroller.

6. A wireless caller information processing system as claimed in claim 1 wherein:

said remote unit further includes a microcontroller connected between said wireless receiving means and said display means;

said microcontroller further including memory means operated in response to receipt of identity signals at said wireless receiving means to operate said display means to provide said visual indication at said remote unit of the identity of said source of said incoming call received at said master unit.

7. A wireless caller information processing system as claimed in claim 6 wherein:

said remote unit further includes unique identification code means connected to said microcontroller and wireless transmission means connected to said microcontroller operated in response to said microcontroller to transmit said unique identification code to said master unit to identify said remote unit.

8. A wireless caller information processing system as claimed in claim 6 wherein:

there is further included a serial data interface connected to said microcontroller adapted to connect information stored in said memory included in said microcontroller to external data utilization means.

9. A wireless caller information processing system as claimed in claim 7 wherein:

said microcontroller includes a plurality of circuit connections to said wireless transmission means and said wireless receiving means, as well as circuit connections to a unique identification code means, a key pad and a serial data interface.

10. A wireless caller information processing system as claimed in claim 4 wherein:

said master unit includes signal distribution means connected to said wireless transmission means operated to distribute signals from said wireless transmitter to said remote unit.

11. A wireless caller information processing system as claimed in claim 10 wherein:

said signal distribution means further includes circuit connections to said wireless receiving means operated to couple signals identifying said remote unit received from said remote unit to said wireless receiving means.

12. A wireless caller information processing system as claimed in claim 7 wherein:

said remote unit includes signal distribution means connected to said wireless transmission means operated to distribute signals from said wireless transmitter to said master unit.

13. A wireless caller information processing system as claimed in claim 12 wherein:

said signal distribution means further include circuit connections to said wireless receiving means operated to couple signals from said master unit received from said master unit to said wireless receiving means.

14. A wireless caller information processing system as claimed in claim 1 wherein:

there is further included intercept means connected to said line interface means at said master unit.

15. A wireless caller information processing system as claimed in claim 14 wherein:

said intercept means include a relay operated to disconnect said line interface unit from said central office telephone line.
