Patent ID: 7138732

Claim:
A security and energy control system comprising: a card reader for generating an identification (ID) code in response to detecting an ID card; a motion sensor for generating a motion signal in response to detecting motion in a field of view of the motion sensor; a temperature sensor for generating a temperature signal based on a temperature detected thereby; a transmitter for generating at least one wireless control signal based on the ID code, the motion signal and/or the temperature signal; a first switch connected between an energy source and an energy consumption device; a first receiver responsive to a first wireless control signal from the transmitter for causing the first switch to connect the energy source to the power consumption device; means for conveying a message on a communication link; and a second receiver responsive to a second wireless control signal from the transmitter for causing the conveying means to convey the message on the communication link, wherein the conveying means includes a first controller for producing the message based on the second wireless control signal, transmitting means responsive to the first controller for transmitting the message on the communication link and a second switch connected between the transmitting means and the communication link, the second switch responsive to the first controller for connecting the transmitting means to the communication link.
