Abstract: A flexible electronic light guide for an endoscope that acts as a heat sink for the light emitting diode (LED). A flexible tube within the light guide extends from the LED to shunt heat away from the LED. The flexible tube may be a solid metal tube that is perforated to be flexible. The flexible tube may also be a braided wire jacket and may enclose a series of metal balls that are in contact with each other. The flexible tube may also be made of a plurality of different metals. The flexible tube may also be a hollow tube and support an air or liquid cooling system or be packed with metal balls that can be as small as grains of sand. The flexible tube may also be a linkage formed from a series of metal components held in tight contact by a spring.

Abstract: A polar mount for a satellite dish antenna has the flattened ends of three metal tubes bolted together to form a triangular base having three corners. Three tubular leg members have their corresponding lower flattened ends joined to the respective corners of the base. One leg member constitutes the polar axis shaft. The other two leg members are telescopic and adjustable in length. The upper ends of the two telescopic leg members and the upper end of the polar axis shaft are connected at a common point to create a pyramid-shaped structure. Brackets having bearings mounted to the outside back of the dish and the polar axis shaft extends through these bearings along an axis aligned with a diameter of the dish. The polar axis shaft is at an angle with respect to horizontal corresponding to the degrees of latitude at the antenna location. A tangent to the dish axis is at a declination offset angle relative to the polar axis shaft. The dish rotates on the polar axis shaft through a look angle.
