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.

Abstract: A system for providing data related to discounted services available near a given location. The system includes a memory storing compressed service data representative of a plurality of services in various locations categorized by type of service and compressed coupon data representative of discounts available for the services. The system also includes a book of coupons corresponding to the discounted services wherein the coupon data includes identifying numbers which identify locations of coupons within the coupon book corresponding to the discounts available for the services. A data entry circuit receives and compresses input data identifying a desired category of services and the given location and a microprocessor, receiving and responsive to the compressed input data, selectively retrieves the service data and coupon data from the memory.
