Abstract
Abstract A communications system particularly adapted for use by police officers and including a portable transceiver, first and second mobile transceivers, and a recording unit. Code generator means is provided which is operatively associated with the portable transceiver. Decoding and switching means is also provided which is controlled by the code generator means and which selectively controls the first and second mobile transceivers and the recording unit. Additional auxiliary safety units may also be provided which are controlled by the code generator means and the decoding and switching means.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
121 words
In a communications system, the combination including a portable radio transmitter, a mobile radio receiver adapted to receive radio frequency signals emanating from said portable transmitter and having an output, a mobile radio transmitter having an input selectively connectable to said output of said mobile receiver, said portable and mobile transmitters transmitting on different frequencies, said mobile transmitter being adapted to receive and transmit signals received from said output of said mobile receiver, code generating means operatively associated with said portable transmitter, decoding means controlled by said code generator means, and switching means controlled by said decoding means and operable to energize the mobile transmitter and to connect said output of said mobile receiver to said input of said mobile transmitter.
Claim 2
Dependent Claim
121 words
In a communications system, the combination including a portable radio transmitter, a mobile radio receiver adapted to receive radio frequency signals emanating from said portable transmitter and having an output, a mobile radio transmitter having an input selectively connectable to said output of said mobile receiver, said portable and mobile transmitters transmitting on different frequencies, said mobile transmitter being adapted to receive and transmit signals received from said output of said mobile receiver, code generating means operatively associated with said portable transmitter, decoding means controlled by said code generator means, and switching means controlled by said decoding means and operable to energize the mobile transmitter and to connect said output of said mobile receiver to said input of said mobile transmitter.
