Abstract: An accessory actuator for an occupant restraint system buckle which gives the owner of an automotive vehicle a choice in rendering the restraint belts in the vehicle more convenient for unlatching. The accessory comprises a molded plastic accessory button which can be installed without the use of separate tools and without having to modify the existing buckle. The button has a head disposed exterior of the pre-existing buckle casing and a neck which extends from the head to join with the pre-existing actuating button of the buckle. The accessory button joins to the pre-existing button by pressing the adhesive containing end of the neck against the pre-existing actuating button.

Abstract: A dummy load for a radio frequency transmitter uses a resistive liquid within a tube of non-conducting material as the load. The tube has grounded conductors at each end, and a centrally-located terminal that provides a load, with respect to ground, across two parallel branches. The output of the radio frequency transmitter is applied between the centrally-located terminal and ground. The ends of the tube are connected into a closed liquid loop that includes a temperature controlling system with a circulating pump, a heater for raising the temperature of the resistive liquid to a given, operating level, if necessary, and a heat exchanger for lowering the temperature of the resistive liquid to the given, operating level, when necessary; whereby the heat generated by the output of the transmitter can be dissipated, and the temperature of the resistive liquid, within the tube, kept at a constant mean temperature to provide a constant resistance under all load conditions.
