Subnet addressable radio activated switch
First Claim
1. A remotely activated control device, comprising:
- a radio receiver;
a response timer;
an assurance means for determining if a series of pulses detected by said radio receiver comprises a number of data bits that is less than the number of data bits required to activate a communication relay network or initiate a radio telephone connection at the end of a time period set by said response timer;
a storage means for digital data representing alphanumerics identifying a specific radio transmitter;
a comparitor for generating a control signal when said comparitor determines said digital data is identical to said series of detected pulses at the end of said time period set by said response timer; and
a switching circuit for activating a user supplied apparatus in response to said control signal.

Abstract
A remotely activated control device responsive to a specific transmitter operating in a frequency band assigned to radio telephone equipment, such as cellular telephone networks, cordless telephones, etc. The control device includes a radio receiver which provides a received pulse train to an assurance logic circuit. The assurance logic circuit determines if the received pulse train is limited to no more than a transmitter identification code and an action code, the combination of which is less than the code required to activate a relay network or initiate a radio telephone connection. Pulse trains accepted by the assurance logic circuit are compared to a stored code by a comparitor. The stored code includes the identification of a specific transmitter or group of transmitters and at least one action code. If the received pulse train matches the stored code, a switching circuit is activated to control a user supplied device.

14. A method for remotely controlling an apparatus, including the steps of:
-
storing data in a memory of a remote control device;
keying an action code into a control radio telephone;
transmitting the electronic identification serial number, ESN, and the mobile identification number, MN, of the control radio telephone combined with the action code previously entered via the key pad;
receiving with said remote control device said transmitted electronic identification serial number, ESN, and mobile identification number, MTN, of the control radio telephone combined with the action code previously entered via the key pad;
comparing said received electronic identification serial number, ESN, and mobile identification number, MN, of the control radio telephone combined with the action code previously entered via the key pad to said data stored in said memory of said remote control device if said received electronic identification serial number, ESN, and mobile identification number, MN, of the control radio telephone combined with the action code previously entered via the key pad comprises data which will not activate a communication relay network or initiate a radio telephone connection; and
activating a switching circuit if said comparing step indicates the received data is identical to said stored data. - View Dependent Claims (15, 16)

17. A remotely activated control device, comprising:
-
a radio receiver;
a pulse train gate for controlling the flow of received data pulses detected by said radio receiver;
means for storing said received data pulses that pass through said pulse train gate;
a pulse train limit means for clearing said means for storing said received data pulses and closing said pulse train gate when pulses passing through said pulse train gate comprise a number of data bits that will activate a communication relay network or initiate a radio telephone connection;
a storage means for alphanumeric data, said alphanumeric data including a transmitter identification code selected from the group of alphanumeric codes including electronic serial numbers and mobile identification numbers identifying a specific radio transmitter and an action code;
a timer for establishing a decode time, said timer initiated by the first of said received data pulse;
a comparitor for generating a control signal when said received data pulses are identical to said alphanumeric data at the end of said decode time; and
a switching circuit for activating a user supplied apparatus in response to said control signal. - View Dependent Claims (18, 19, 20)

21. A method for remotely controlling an apparatus, including the steps of:
-
entering an alphanumeric code into a control radio telephone via its key pad;
said code comprising fewer data bits than are required for initiating a telephone connection;
transmitting said alphanumeric code via said control radio telephone when said control radio telephone is within the reception range of a radio receiver responsive to signals transmitted by said control radio telephone without the need for an intervening relay means;
detecting said transmitted alphanumeric code with said radio receiver;
determining if said transmitted code comprises a number of data bits that is less than the number of data bits required to activate a communication relay network or initiate a radio telephone connection at the end of a time period set by a response timer;
comparing said detected alphanumeric code to a stored alphanumeric code incorporating the identification code of said control radio telephone if said transmitted alphanumeric code is less than the number of data bits required to activate a communication relay network or initiate a radio telephone connection at the end of said time period set by said response timer; and
activating a switching means when said comparison indicates said detected alphanumeric code exactly matches said stored alphanumeric code.
