Abstract: A system for managing engine idling operation is provided. The system includes a communication center communicatively coupled to at least one vehicle having an engine. A database is provided that has idling regulation information stored therein based, at least, upon geographic location. The vehicle with the engine further includes an idling detection system. The idling detection system includes an idle detect sensor, a processor and a location information module, such as a GPS receiver. The processor is operably coupled to the idle detect sensor. The location information module is operably coupled to the processor to provide position information relative to the vehicle. The processor is configured to monitor vehicle idling and provide a warning thereof based upon an idling regulation stored in the database selected by current vehicle position information.

Abstract: A locator system comprises a locator device, a control center, a workstation and a computerized interface. The control center and the locator device are configured to communicate via cellular and pager signals.

Abstract: A locator apparatus includes a receiver for receiving location information indicative of a location of the receiver. A memory is coupled to the receiver and stores the location information. A cellular transmitter is coupled to the memory and the receiver and transmits the location information to a second receiver. A data processing station processes the location information to determine the location of the receiver.
