Abstract
A system and method for providing a remote alert from a clock radio to a user at a predetermined time without disturbing others around him. The clock radio is preferably a superheterodyne receiver and includes an alert signal circuit for providing radio frequency alert signals at a predetermined alarm time and a radio frequency transceiver for receiving broadcast radio frequency signals and for transmitting radio frequency signals including the broadcast radio frequency signals and the radio frequency alert signals. A timing circuit in the clock radio includes a coincidence detecting circuit which detects the coincidence between the time of day and the predetermined alarm time, and causes the alert signal circuit to provide an alert signal to the radio frequency transceiver for transmission to a selected wireless remote alert device at the predetermined time. The selected wireless remote alert device receives radio frequency signals at the predetermined time, including the radio frequency alert signals, and processes such received radio frequency signals in a manner similar to the superheterodyning technique. The thus processed signal will then be provided to a transducer in the wi…
