A remote convenience system (10), via an associated method, causes remote control performance of a function. A portable, actuatable transmitter (14) of the system (10) transmits signals (16) that convey a function request during first portions of repeating, predetermined duration, request periods, and idles during second portions of the request periods. A receiver/controller (18) of the system (10) performs the requested function, within a response period of predetermined duration that begins upon transmitter actuation, in response to a received function request. Within the receiver/controller (18), power control circuitry (62) maintains receive circuitry (56) in a power OFF state for a first portion of a repeating, predetermined duration, power-save period, and cycles the power ON and OFF in a sequence for a second portion of the power-save period such that the receive circuitry (56) is eventually in the power ON state during one of the first portions of one of the request periods and such that one of the transmitted signals (16) is detected. The power control circuitry (62) maintains the power ON once the signal is detected to receive a next subsequent signal (16).

[ Having described the invention, the following is claimed:] [1.]1. A remote convenience system for remote control of a function, said system comprising:a portable, actuatable transmitter for requesting performance of a remote control function; anda receiver/controller for causing performance of the requested function, within a response period of predetermined duration that begins upon transmitter actuation, in response to a received function request;said transmitter including means for transmitting signals conveying a function request during first portions of repeating, predetermined duration, request periods and for idling during second portions of the request periods;said receiver/controller including receiver means having an ON state for detecting and receiving transmitted signals and an OFF state, and power control means for maintaining said receiver means in the OFF state for a first portion of a repeating, predetermined duration, power-save period and for cycling said receiver means between the ON and OFF states in a sequence for a second portion of the power-save period such that said receiver means is eventually in the ON state during one of the first portions of one of the request periods of said transmitter and that one of the transmitted signal is detected, and said power control means for maintaining said receiver means in the ON state once said receiver means detects a signal such that a next subsequent signal is received and the requested function performed within the response time period.
