Abstract: Air conditioning temperature measurement device for use with a valve actuated refrigerant recharge assembly operates in conjunction with a pressurized refrigerant bottle and a-remote temperature sensor enabled by radio frequency (RF) wireless communication. Sampled temperatures at an output vent of an air-conditioned cabin and rate of temperature change at the inlet modulate recharge of refrigerant into low pressure side of a phase change A/C control system. Automated sensing of the rate of temperature change in an air conditioner outlet vent, and modulation of refrigerant refill rate, ensure sufficient refrigerant is introduced to improve cooling efficiency while overfill is prevented by refrigerant valve control as rate of temperature change approaches a parabolic minimum.

Abstract: The present invention provides novelty eye goggles comprising an adjustable elastic rubber strap attached to the clear plastic frames of standard, vented safety goggles, with two hollowed-out 12 ounce aluminum beer cans affixed to the eye-sockets, protruding outward from the frames, suspended horizontally and running parallel to the ground.
