Radar detector responsive to vehicle speed
First Claim
1. An apparatus for use on a vehicle comprising:
- a radar detecting circuit adapted to be on the vehicle for detecting a radar signal originating from a radar source remote from the vehicle and for selectively providing a radar detect signal in response to detecting the radar signal;
a global positioning system (GPS) receiver adapted to be on the vehicle for determining a speed of the vehicle and for providing a GPS speed signal representative of the vehicle speed; and
an alarm responsive to both the radar detect signal and the GPS speed signal for providing an alarm indication in the event that the GPS speed signal indicates an unacceptable vehicle speed and the radar detect signal indicates that a radar signal has been detected.

Abstract
A radar detecting circuit adapted to be on the vehicle detects a radar signal and selectively provides a radar detect signal in response to detecting the radar signal. The vehicle'"'"'s speed is determined such as indicated by a tachometer signal or a global positioning system (GPS) receiver adapted to be on the vehicle and providing a GPS speed signal representative of the vehicle speed. An alarm responsive to both the radar detect signal and the GPS speed signal provides an alarm indication when a radar signal is detected and the vehicle speed is above a preset maximum, such as the speed limit. The operator indicates the present maximum speed via an input device such as a keypad or via voice recognition software.

10. An apparatus for use on a vehicle and for use with a speed signal representative of the speed of the vehicle, said apparatus comprising:
-
a radar detector adapted to be on the vehicle for detecting a radar signal originating from a radar source remote from the vehicle and for selectively providing a radar detect signal in response to detecting the radar signal; an alarm for providing an alarm indication when energized; and a circuit connected to the alarm and receiving the radar detect signal and the speed signal, said circuit selectively energizing the alarm in response to both the radar detect signal and the speed signal in the event that the speed signal indicates an unacceptable vehicle speed and the radar detect signal indicates that a radar signal has been detected. - View Dependent Claims (11, 12, 13, 14, 15)

16. An apparatus for providing an alarm indication for a vehicle comprising:
-
a detector detecting a radar signal originating from a radar source remote from the vehicle and impinging on the vehicle; an input device defining a maximum acceptable speed of the vehicle; a speed circuit determining an actual speed of the vehicle; and an actuating circuit selectively energizing an alarm to provide the alarm indication when the radar signal is detected by the detector and the speed circuit determines that the actual speed of the vehicle equals or exceeds the maximum acceptable speed of the vehicle as defined by the input device. - View Dependent Claims (17, 18, 19, 20, 21)

22. A method of providing an alarm indication for a vehicle comprising the steps of:
-
detecting a radar signal originating from a radar source remote from the vehicle and impinging on the vehicle; defining a maximum acceptable speed of the vehicle; determining a speed of the vehicle; and actuating an alarm to provide the alarm indication when a radar signal is detected and the determined speed of the vehicle equals or exceeds the maximum acceptable speed of the vehicle.
