Abstract: A flashlight senses when it is picked up, and then automatically turns on. When the flashlight is released or set back down, it automatically turns off. Touch or contact sensors sense the touch of a human hand, causing a circuit in the flashlight to switch on a light source, such as an LED. The flashlight is advantageously designed so that when grasped or picked up, the fingers of the user's hand lay over touch sensors. Various types of touch sensors may be used. The touch sensors may operate electrically, and without any movement, or moving parts.

Abstract: A solar circulator and converter which is driven by a solar generator; the fan or impeller is mounted in an impeller housing. On the surface opposite the impeller housing is a solar panel with mounting elements which can be affixed or mounted on such things as car windows. The impeller or fan blows and circulates air inside the car whether the car is stationery or in motion. The circulator also converts part of the solar radiation into forms of energy other than heat and thereby reduces temperature.
