Abstract: A car locator system includes a hand held locator which receives information with regard to the location of a vehicle and then stores that information for display on the hand held locator. The hand held locator could be a key fob having buttons to command operation to the vehicle. When a command signal is transmitted to the vehicle, the vehicle then transmits its position location to the hand held location for storage. In this way, an operator will be able to have an indication of the location of the vehicle. The vehicle can communicate with GPS satellites to determine its location, or may communicate with ground based local transmitters. The ground based local transmitters can be programmed to provide an indication of the location of the vehicle within a parking lot.

Abstract: A steering position indicator system for a boat provides the boat operator with a signal to indicate when the boat's steering control means is centered with respect to the boat's centerline. The system employs a proximity sensor mounted on the hull or transom of the boat and a sensor actuator mounted to a steering linkage bar extending between left and right steerable outdrive units or rudders. The proximity sensor and sensor actuator are positioned relative to one another such that the sensor detects the actuator and closes a circuit only when the outdrive units are centered with respect to the boat's centerline. The indicator includes a light or buzzer and is mounted adjacent a helm position of the boat and alerts the boat operator when the sensor detects the sensor actuator. The proximity sensor may be optical, magnetic, or inductance. A switch allows the boat operator to select either an audible or a visible signal.

Abstract: A system for accurately measuring the direction in which a magnetometer is to be set has a simple construction and is little affected by iron structures on a hull. The system has a magnetometer which includes an excitation source, a magnetic core, an excitation AC winding and an output winding which are both wound around the magnetic core. The output winding is composed of two series connected coils which are wound around the magnetic core and have an equal number of turns. The measuring system applies an alternating current to the core having an amplitude large enough to saturate the magnetic core, and obtains an output from the output winding corresponding to the angle formed between the geomagnetic field direction and an imaginary line obtained by interconnecting the point of connection of the two coils and the central point of the magnetic core.
