Hands-free remote entry system
First Claim
1. A hands-free remote entry system sensitive to the presence of an object and, said system comprising:
- a base transceiver having a sleep mode and an active mode of operation, said base transceiver comprising;
a wake-up sensor for switching from said sleep mode to said active in response to detecting the object;
a base transmitter for transmitting a wake-up/data signal in response to detecting the presence of the object;
a base receiver for receiving an identification/data signal; and
an output actuator for actuating the system; and
a fob transceiver having a sleep mode and active mode of operation comprising;
a wake-up receiver for switching said fob transceiver from said sleep mode to said active mode in response to receiving said wake-up/data signal; and
an identification transmitter for transmitting said identification/data signal in response to said wake-up receiver receiving said wake-up/data signal, wherein said output actuator actuates the system upon receipt of said identification/data signal by said base receiver.

Abstract
The present invention teaches a hands-free remote entry system primarily for vehicles. This system comprises a base transceiver having wake-up sensors for automatically detecting an object. Once an object is detected, a transmitter within the base transceiver transmits a wake-up/data signal to a fob transceiver. A wake-up receiver within the fob transceiver receives the wake-up/data signal. Upon receipt of the wake-up/data signal, the fob transceiver transmits an identification/data signal, via a transmitter, back to a receiver in the base transceiver. In response to receiving the identification signal, output drivers from the base transceiver actuate a door lock system and an auto theft system.

17. A hands-free remote entry system for remotely actuating a plurality of vehicle locks, said system being sensitive to the presence of an object and comprising:
-
a base transceiver having a sleep mode and an active mode of operation, said base transceiver comprising; a plurality of wakeup sensors for switching from said sleep mode to said active mode in response to detecting the object within one of a plurality of zones positioned about a vehicle to wake-up said base transceiver; a base transmitter for transmitting a wake-up/data signal sequentially from each of said zones in response to detecting the object; a base receiver for receiving an identification/data signal from one of said zones; and an output actuator for actuating at least one of the plurality of vehicle locks, each of the plurality of the zones associated with at least one of said plurality of vehicle locks; and a fob transceiver comprising; a wake-up receiver for receiving said wake-up/data signal from one of said zones to wake-up said fob transceiver; and an identification transmitter for transmitting said identification/data signal from one of said plurality of zones in response to said wake-up receiver receiving said wake-up/data signal, wherein said output actuator actuates the at least one of the vehicle locks associated with the zone from which said identification/data signal is transmitted by said fob transceiver. - View Dependent Claims (18, 19, 20, 21)

22. A method for remotely locking and unlocking a vehicle lock in a hands-free manner sensitive to the presence of an object, said method comprising the steps of:
-
a) detecting the object in one of a plurality of zones about a vehicle; b) switching between a sleep mode of operation and an active mode operation in response to said step of detecting the object; c) transmitting a wake-up/data signal sequentially from each of said zones in response to said step of detecting the object; d) receiving said wake-up/data signal transmitted from a first one of said zones with a fob transceiver; e) transmitting an identification/data signal from said fob transceiver in response to said step d); f) receiving said identification/data signal from said fob transceiver; and g) actuating the vehicle lock at said first one of said zones in response to receiving said identification/data signal. - View Dependent Claims (23, 24)
