Abstract
Abstract A vehicle communication system includes a trainable transmitter that is connected with the antenna associated with the AM/FM radio receiver in the vehicle. The trainable transmitter preferably is capable of learning a variety of communication signals and then later, selectively transmitting them to communicate with a variety of external, remotely located devices. A system designed according to this invention allows a single antenna to be used for emitting signals and receiving signals and, moreover facilitates communication with a variety of remotely located devices such as a garage door opener and a home security system.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
92 words
A vehicle communication system comprising: an antenna supported on the vehicle: an AM/FM radio receiver coupled to said antenna for receiving broadcast radio signals collected by said antenna; a transmitter for selectively generating a plurality of communication signals, wherein each communication signal communicates with a different corresponding device remote from the vehicle, said transmitter being coupled to said antenna for emitting the communication signals; and a plurality of manual actuators, each corresponding to a different one of the devices, for causing said transmitter to generate the communication signal for the corresponding device.
Claim 2
Dependent Claim
92 words
A vehicle communication system comprising: an antenna supported on the vehicle: an AM/FM radio receiver coupled to said antenna for receiving broadcast radio signals collected by said antenna; a transmitter for selectively generating a plurality of communication signals, wherein each communication signal communicates with a different corresponding device remote from the vehicle, said transmitter being coupled to said antenna for emitting the communication signals; and a plurality of manual actuators, each corresponding to a different one of the devices, for causing said transmitter to generate the communication signal for the corresponding device.
Claim 3
Dependent Claim
93 words
The system of claim 1, further comprising a function selector coupled between said antenna and said radio receiver and between said antenna and said transmitter, said function selector having a first operative condition where said radio receiver is coupled to said antenna and said transmitter is not coupled to said antenna and a second operative condition where said transmitter is coupled to said antenna and said radio receiver is not coupled to said antenna and wherein said selector is normally in said first operative condition and selectively placed into said second operative condition.
Claim 4
Dependent Claim
25 words
The system of claim 2, further comprising an electronic controller coupled to said function selector for selectively placing said selector into said second operative condition.
Claim 5
Dependent Claim
46 words
The system of claim 1, further comprising a function switch coupled between said antenna and said transmitter and between said antenna and said radio receiver, said function switch selectively coupling said transmitter to said antenna such that the communication signal can be emitted by said antenna.
Claim 6
Dependent Claim
44 words
The system of claim 4, further comprising an electronic controller in communication with said function switch and said transmitter, said electronic controller selectively activating said switch to selectively couple said transmitter to said antenna such that said transmitted signal is emitted by said antenna.
Claim 7
Dependent Claim
20 words
The system of claim 1, wherein said manual actuators comprise a plurality of manually actuatable switches coupled to said transmitter.
Claim 8
Dependent Claim
26 words
The system of claim 6, further comprising a housing that houses said radio receiver, said transmitter and said function switch and supports said manually actuatable switches.
Claim 9
Dependent Claim
76 words
The system of claim 1, further comprising: a vehicle receiver coupled to said antenna for receiving from a device remote from said vehicle a second communication signal collected by said antenna for initiating a vehicle function; and a signal separator coupled between said antenna and said radio receiver and between said antenna and said vehicle receiver for directing the collected radio signals to said radio receiver and the collected second communication signal to said vehicle receiver.
Claim 10
Dependent Claim
61 words
The system of claim 8, further comprising a function switch that includes a first port coupled to said antenna, a second port coupled to said transmitter and a third port coupled to said signal separator and wherein said function switch is actuatable to selectively allow signal communication between said first and second ports or between said first and third ports, respectively.
Claim 11
Dependent Claim
56 words
The system of claim 9, wherein said signal separator has an input coupled to said antenna, a first output coupled to said radio receiver and a second output coupled to said vehicle receiver and wherein the collected radio signals are directed through said first output and the collected communication signal is directed through said second output.
Claim 12
Dependent Claim
16 words
The system of claim 8, wherein said transmitter and said vehicle receiver comprise a cellular telephone.
Claim 13
Dependent Claim
102 words
A vehicle communication system comprising: an antenna supported on the vehicle: an AM/FM radio receiver coupled with said antenna for receiving broadcast radio signals that are collected by said antenna; and a transmitter for selectively generating a communication signal, said transmitter being coupled to said antenna for emitting the communication signal for communicating with a device located remotely from the vehicle, wherein said transmitter includes a second receiver for receiving an externally transmitted signal and a memory device for capturing and storing the received externally transmitted signal such that said transmitter later generates the communication signal consistent with the externally transmitted signal.
Claim 14
Dependent Claim
102 words
A vehicle communication system comprising: an antenna supported on the vehicle: an AM/FM radio receiver coupled with said antenna for receiving broadcast radio signals that are collected by said antenna; and a transmitter for selectively generating a communication signal, said transmitter being coupled to said antenna for emitting the communication signal for communicating with a device located remotely from the vehicle, wherein said transmitter includes a second receiver for receiving an externally transmitted signal and a memory device for capturing and storing the received externally transmitted signal such that said transmitter later generates the communication signal consistent with the externally transmitted signal.
Claim 15
Dependent Claim
27 words
The system of claim 12, wherein said transmitter further comprises a voltage controlled oscillator that generates a signal consistent with the stored signal from said memory device.
Claim 16
Dependent Claim
14 words
The system of claim 12, wherein said second receiver comprises a frequency independent receiver.
