Abstract: An inflatable protective cover for golf club bags includes first, second, third and fourth flexible walls. An inner side surface of a lower part of the first wall frictionally engages the golf club bag while an upper part thereof covers an opening in the golf club bag and the portion of any clubs projecting from the opening. A lower part of the second flexible wall is sealingly attached to the lower part of the first wall while an upper part thereof overlays the upper part of the first wall to form a first, normally inflated, air bladder therebetween. Similarly, a lower part of the third flexible wall is sealingly attached to the lower part of the second wall while an upper part thereof to form a second, normally deflated, air bladder therebetween. An air supply system comprised of a pump bulb and a flexible air conduit in communication with the first air bladder provides a quantity of air to the protective cover to inflate the first air bladder.

Abstract: Apparatus for optimizing operation of an engine-driven vehicle.

Abstract: An apparatus to provide protection for electronic devices which receive power for their operation at least in part from a vehicle's electrical system and battery. The electronic device protecting apparatus has an electrical system voltage sensor, an engine start sensor, and an electronic device decoupler interconnected such that the electronic devices are decoupled from the electrical system and battery when the battery voltage drops below a predetermined level and when the engine is being started. The preferred apparatus allows the operator to select between a warning that system voltage is low and an automatic restart of the vehicle's engine and charging system. The apparatus further includes a bypass function to accommodate electronic devices which draw temporarily high current.

Abstract: An electronic device protecting apparatus and associated methods of manufacturing provide protection for electronic devices which receive power for their operation at least in part from a storage battery. In a preferred embodiment, an electronic device protecting apparatus has a battery voltage sensor, an engine start sensor, and an electronic device decoupler. The electronic devices are decoupled from the battery when the battery voltage drops below a predetermined level, and when the engine is being started.
