DOUBLE PROXIMITY-INTERROGATIVE SMART FOB SWITCHING OF ELECTRICAL DEVICE
First Claim
1. A smart fob for interfacing with a smart module, comprising:
- a low frequency receiver for receiving a first password and a smart module ID number in a low frequency signal;
a memory for storing a registration number with which the smart fob is registered to the smart module, a smart fob ID number for the smart fob and a stored smart module ID number;
a processor for providing a second password derived from the first password and the registration number of the smart fob;
a smart module ID detector connected to the low frequency receiver for waking-up the processor if the received smart module ID number in the low frequency signal matches the stored smart module ID number in the memory; and
a high frequency transmitter for transmitting the second password in a high frequency signal.

7. A smart module for actuating an electrical device in response to a smart fob, comprising:
-
a low frequency transmitter for transmitting a first password and a smart module ID number in a low frequency signal; a polling timer controlling a length of time between transmissions of the first password along with the smart module ID number; a high frequency receiver for receiving a high frequency signal including a second password; a memory for storing a registration number with which the smart fob is registered to the smart module and for storing the smart module ID number; a processor for decrypting the second password and determining if the second password is from the smart fob registered to the smart module; a reset timer for running a predetermined period when the processor determines a second password is from the smart fob registered to the smart module; and a directed actuator for electrical actuation of the electrical device while the reset timer runs. - View Dependent Claims (8, 10, 11, 12, 13, 14, 15)

16. A system for actuating an electrical device, comprising:
-
a low frequency transmitter in the smart module for transmitting a first password and a smart module ID number in a low frequency signal; a low frequency receiver in a smart fob for receiving the first password and the smart module ID number in the low frequency signal; a first processor in the smart fob for providing a second password derived from the first password and a registration number with which the smart fob is registered to the smart module; a high frequency transmitter in the smart fob for transmitting a high frequency signal including the second password and a smart fob ID number; a high frequency receiver in the smart module for receiving the high frequency signal including the second password and the smart fob ID number; a second processor in the smart module for decrypting the second password and determining if the second password is from the smart fob registered to the smart module; a reset timer for running a predetermined period when the second processor determines the second password is from the smart fob registered to the smart module; and a directed actuator for electrical actuation of the electrical device while the reset timer runs. - View Dependent Claims (17, 18, 19, 20)
