Abstract
Abstract A system for deflating a tire on a wheel of a vehicle upon theft of the vehicle, comprising a wheel mounted unit and at least one remote unit for deactivating the wheel mounted unit via remote signals. The wheel-mounted unit is automatically armed upon stopping of the vehicle and comprises a pressure release assembly mounted in an orifice of the wheel for deflating the tire, a sensor adapted to sense wheel rotation and wheel speed, and a controller connected to the sensor and pressure release assembly for activating the pressure release assembly in response to wheel rotation sensed by the sensor. There is a receiver for receiving incoming RF signals from the remote unit, and a power supply connected to the pressure release assembly, sensor, controller and receiver. Each wheel could have its own wheel-mounted unit. After deflation, the wheel-mounted units are automatically re-set.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A system for deflating a tire on a wheel of a vehicle, comprising: at least one wheel-mounted unit comprising: a pressure release assembly mounted in an orifice of the wheel for deflating the tire; a sensor mounted to the wheel and adapted to sense wheel rotation; a controller connected to said sensor and pressure release assembly, said controller being adapted to actuate said pressure release assembly in response to wheel rotation sensed by the sensor; a receiver connected to said controller and adapted to receive incoming RF signals; and a power supply connected to and supplying electrical power to said pressure release assembly, sensor, controller and receiver; and at least one remote unit adapted to transmit an RF signal to the receiver to deactivate the wheel mounted unit.
Claim 2
Independent Claim
128 words
A system for deflating a tire on a wheel of a vehicle, comprising: at least one wheel-mounted unit comprising: a pressure release assembly mounted in an orifice of the wheel for deflating the tire; a sensor mounted to the wheel and adapted to sense wheel rotation; a controller connected to said sensor and pressure release assembly, said controller being adapted to actuate said pressure release assembly in response to wheel rotation sensed by the sensor; a receiver connected to said controller and adapted to receive incoming RF signals; and a power supply connected to and supplying electrical power to said pressure release assembly, sensor, controller and receiver; and at least one remote unit adapted to transmit an RF signal to the receiver to deactivate the wheel mounted unit.
Claim 3
Dependent Claim
15 words
The system according to claim 1, wherein the remote unit is a portable, hand-held device.
Claim 4
Dependent Claim
55 words
The system according to claim 1, wherein the pressure release assembly comprises a valve in the orifice, said valve being connected to the power supply, wherein electrical current from the power supply in response to a signal from the controller causes the valve to retract out of the orifice and release pressure from the tire.
Claim 5
Dependent Claim
20 words
The system according to claim 3, wherein the valve is automatically reset in the orifice after deflation of the tires.
Claim 6
Dependent Claim
20 words
The system according to claim 1, wherein the pressure release assembly is mounted on an interior surface of the wheel.
Claim 7
Dependent Claim
52 words
The system according to claim 1, further comprising a transmitter in the wheel-mounted unit adapted to send RF signals to a remote location, and an indicator mounted to the dashboard of the vehicle, said indicator indicating activation and deactivation of the wheel mounted unit in response to a signal from the transmitter.
Claim 8
Dependent Claim
32 words
The system according to claim 6, wherein the transmitter sends a signal to the indicator prior to actuation of the pressure release assembly to warn of activation of the pressure release assembly.
Claim 9
Dependent Claim
24 words
The system according to claim 7, further comprising an audible alarm in the indicator unit, said alarm sounding upon a signal from the transmitter.
Claim 10
Dependent Claim
18 words
The system according to claim 6, wherein the indicator is connected to and powered by the vehicle's battery.
Claim 11
Dependent Claim
15 words
The system according to claim 1, wherein the power source is at least one battery.
Claim 12
Dependent Claim
32 words
The system according to claim 1, further comprising an additional remote unit mountable within the vehicle and comprising a power source and a button, wherein pressing the button deactivates the wheel-mounted unit.
Claim 13
Dependent Claim
38 words
The system according to claim 1, wherein the wheel-mounted unit is automatically activated to monitor wheel rotation and activate the pressure release assembly upon the sensor sensing an absence of wheel rotation for a predetermined period of time.
