Abstract: The present invention provides a cove illumination module for use in a plurality of illumination applications wherein a particular type of cove type illumination pattern is desired due to close proximity between the cove illumination module and a to-be-illuminated surface. The cove illumination module comprises a substrate to which a plurality of light-emitting elements is operatively connected. Optionally, the substrate can form a base portion of the cove illumination module. An external housing unit is sealingly mated with the substrate in order to environmentally seal the light-emitting elements. The external housing unit comprises one or more optical elements which can shape the beams of light emitted by the light-emitting elements under operating conditions and generate a desired illumination pattern on a lit surface, thereby providing a cove type illumination pattern.

Abstract: A device for rotating with a rotatable first member includes a second member having a portion engageable with the first member. The portion has a first part and a second part which is resiliently biased away from the first part. The second member tightly engages the first member. There may be a device for measuring rotation of the shaft such as a potentiometer. The rotation measuring device may include an electrical connector for the potentiometer including a socket and a post which is pressable into the socket. The device may also include a rotationally adjustable connector. There may be a coupling connected to the second member which includes a third member with a portion having n sides and a fourth member with a portion having n sides which receives the portion of the third member in a mating relationship, thereby allowing the device to be adjusted to a total of at least m.n rotational positions.
