Patent ID: 7409209

Claim:
A system for using a telephone signal to control transmission of a wireless remote control signal for controlling a device, comprising: (a) a telephone having a keypad comprising a plurality of switches that are selectively activatable; (b) a signal monitoring circuit that is responsive to characteristics of a signal associated with the telephone, said signal monitoring circuit transmitting a predefined control signal in response to detecting a predefined state of the signal, after the signal monitoring circuit has learned the predefined control signal; said predefined control signal having a characteristic that effects a controlled function on a device that is controlled thereby; (c) a learning module configured to learn the predefined control signal from a first remote control associated with the device; wherein the signal monitoring circuit does not comprise the first remote control; (d) a memory in which characteristics for a plurality of predefined control signals, including at least one predefined control signals for adjusting a volume setting, are stored for use in controlling a device, said signal monitoring circuit being coupled in communication with the memory for accessing the characteristics of the plurality of predefined control signals and transmitting a specific one of the plurality of predefined control signals retrieved from the memory, where the specific one of the plurality of predefined control signals is selected in response to a detected state of the signal associated with the telephone; and (e) an audibility suppressing module configured to suppress the audibility of a DTMF signal by another party who is coupled in communication with a user activating any of the plurality of switches to produce the DTMF signal.
