## Abstract

An object-detection system for use with a police vehicle that is operative to provide an alarm to the police officer sitting in the vehicle of an approaching object. The system includes an object-detection device and at least one alarm generator in communication with the object-sensing device wherein the alarm generator is operative to generate an alarm upon receiving an electrical signal from the object-sensing device indicative of an object approaching a police vehicle.

## Claims

### Claim 1

An object detection system for use in alerting a police officer to an approaching object while the officer is sitting within a police car, the system comprising:
an object-sensing device disposed on a spotlight of the police vehicle, the object-sensing device operating to only sense an object approaching the front the police vehicle; and
an alarm generator in communication with the object-sensing device, said alarm generator operative to receive an electrical signal from the object-sensing device and thereafter to generate an alarm to alert the police officer of an approaching object.

### Claim 2 (depends on 1)

The object detection system of claim 1, wherein the object-sensing device is a motion detector.

### Claim 3 (depends on 1)

The object-detection system of claim 1, wherein the alarm generator is a police radio.

### Claim 4

A method of alerting a police officer to an approaching object while an officer is sitting in a police vehicle, said method comprising the steps of:
disposing an object-sensing device on a spotlight of the police vehicle, the object-sensing
device operating to only sense an object approaching the front the police vehicle;
disposing an alarm generator on the police vehicle; and
providing a communication link between said object-sensing device and said alarm generator whereby upon detecting an approaching object, the object-sensing device transmits an electrical signal to the alarm generator that causes the alarm generator to provide an alarm to the police officer.

### Claim 5 (depends on 4)

The method of claim 4, wherein the object-sensing device is disposed on the vehicle as original equipment.

### Claim 6 (depends on 4)

The method of claim 4, wherein the object-sensing device is disposed on the vehicle as an aftermarket product.

### Claim 7

An object detection system for use in alerting a police officer to an approaching object while the officer is sitting within a police car, the system comprising:
an object-sensing device disposed on a spotlight of the police vehicle, the spotlight being movably mounted to the vehicle so that the spotlight may be aimed in a predetermined direction, the object-sensing device operating to only sense an object approaching the police vehicle from direction in which the spotlight is aimed; and
an alarm generator in communication with the object-sensing device, said alarm generator operative to receive an electrical signal from the object-sensing device and thereafter to generate an alarm to alert the police officer of an approaching object.

### Claim 8 (depends on 7)

The object detection system of claim 7, wherein the object-sensing device is a motion detector.

### Claim 9 (depends on 7)

The object-detection system of claim 7, wherein the alarm generator is a police radio.
