Abstract: The present invention provides an adaptable key holder for a remote control transmitter. This includes a remote control transmitter (101) with buttons (102) for activating functions typically located on one surface, and a detachable ring (200) encompassing the remote control transmitter (101) and having a feature to captivate keys (105). This captivating feature (105) feature can be oriented either adjacent or opposite the most used transmitter button.

Abstract: A circuit board (2) for receiving a component (38) requiring heat sinkage. The circuit board has a base portion (4) and a heat sink form portion (6) integral with the base portion. The heat sink form portion has a heat sink form and a coating (58) of thermally conductive material thereon to produce a heat sink. The heat sink has an aperture (32, 34) between a front surface (10) for contacting the component and a back surface (12) remote from the component to allow heat to be conducted directly from the front surface to the back surface. An integral resilient clamp (46-52) holds the component in contact with the heat sink. The integral nature of the base portion, the heat sink and the clamp provides a simple one piece board and the aperture enhances the heat sink efficiency by providing a direct heat conduction path to the back surface.
