GPS-based controller module
First Claim
1. An intergral GPS controller module provided in a single module, comprising:
- a global positioning system (GPS) receiver for providing at an output terminal thereof geographic information corresponding to a respective geographic position of a user;
map means, having an input terminal, connected to the output terminal of the GPS receiver, for receiving geographic position information data from the output terminal of the GPS receiver and for providing output map information;
wherein the map means provides a predetermined functional representation of a characteristic as a function of geographic position;
wherein the map means uses zones defined by a route specific by a distance along the centerline of a track and maximum distance across the track relative to said centerline;
logic means, having a first input terminal connected to the output terminal of the GPS receiver and having an output terminal for providing predetermined logic output values corresponding to geographic position information;
wherein said map means has as output terminal, connected to a second input terminal of the logic means, for providing the logic means with output map information; and
wherein said GPS receiver, said map means, and said logic means are combined as an intergral unit in a single module.

Abstract
A GPS-based integrated controller module combines in a single integrated package or module a GPS receiver, a map, and a logic or decision module which provides an output control signal or control code. The map of the integrated module provides various representations. Continuous functions are provided with various types of coordinate systems, which can use interpolation between reference points in a grid system, or Taylor series representations. The integrated module performs discrete output functions such as providing a control code or a user'"'"'s location either within or out of a particular closed area or polygonal zone, where each location shares a common characteristics with the other locations in the zone.
