Abstract: A method and system for locating and tracking the geographic position of a remote unit worn or carried by a user comprises a battery powered remote unit which upon user activation receives geographic position signals from geographic positioning satellites. The geographic position signals are encoded with a unique code associated with the remote unit and then transmitted from the remote unit to a central control center. The geographic position of the remote unit is determined according to the geographic position signals and then relayed to a computer network database server system. The geographic position along with personal information previously stored on the server system is then displayed at a network location such that a search for the wearer of the remote unit can be initiated by persons having access to the network location. Following initial activation, the remote unit receives and transmits signals only at predetermined time intervals so as to conserve battery power of the remote unit.

Abstract: A windshield wiper assembly for connection to a windshield wiper retainer assembly of a vehicle comprises a housing having a pair of flexible side walls presenting wiping edges depending therefrom and adapted for contact with a windshield. A top wall of the housing spans the side walls and forms a channel therebetween. The top wall further defines at least one aperture in an end thereof. The wiper assembly further includes an elongated heater member having a structure releasably slidable in the channel through the aperture in the top wall. The wiper assembly further includes a plug for connecting a heating element of the heater member to the battery of the vehicle. The heater member cooperates with the side walls to direct heat from the heating element onto the wiper edges and onto the windshield itself. The heater member is slidably interchangeable with a third wiper, the third wiper including a structure that is releasably slidable within the channel.
