Abstract: A lighting device and kit includes a power source disposed within the device. The lighting device includes a housing coupled to a light source. The lighting device includes an attachment member disposed on the housing that selectably couples and decouples the housing to and from a surface. The lighting device includes a motion sensor functionally coupled to the light source such that the light source changes to an on mode when motion is detected. The motion sensor is limited to only detecting motion that occurs at a region above the level of the motion sensor. The lighting device includes a direction indicator that is selectably adjustable between indicating various directions and coupled to the housing.

Abstract: An air treating device having a bellows box in which is mounted a bellows compressor formed of two spaced apart diaphragms having memory-shaped metal alloy elements embedded therein. The diaphragms are caused to contract and expand by selective heating of the memory-shaped metal alloy elements. The bellows compressor is supported spaced in the bellows box whereby air can flow through the box and as the bellows expand the air in the box is cooled and expelled. As the diaphragms of the bellows compressor contract, more air is sucked into the bellows box and at the same time the refrigerant fluid inside the bellows is expelled into a condenser where it is condensed to liquid. When the refrigerant liquid enters into the bellows it is vaporized and cools the bellows walls in their expanded state and the diaphragms act as a heat exchanger to cool air in said bellows box and expel it therefrom.
