WIRELESS REMOTE SWITCHING SYSTEM

摘要

A wireless remote switching system having a transmitter (12) with a telephone keypad (12A) for a user to enter digits via the keys. The transmitter also has a microphone (12C) into which the voice of the user can be directed. The transmitter broadcasts DTMF tones generated from the user's keypad input, or it will broadcast the voice of the user, depending of the user's input to the transmitter. The system also includes a receiver (14) that detects either the broadcast DTMF tones or the voice of the user. After detecting the broadcast, the receiver digitizes the broadcast it has received. The data is then compared to previously stored data kept in the receiver's memory. If a match occurs, the receiver (14) will send a signal to throw a switch associated with an electrical appliance, such as a garage door opener (22), to regulate the power to the appliance.
