    摘要: An electroactive polymer actuator (10) is disclosed for use in various applications including camera diaphragms and lenses. The actuator (10) converts electrical energy to mechanical energy and comprises, in one embodiment, at least two flexible electrodes (15, 25); a transparent elastic non-conductive material (20) having a substantially constant thickness, the transparent elastic non-conductive material (20) arranged in a manner which causes the transparent elastic non-conductive material (20) to compress in a first direction orthogonal to the thickness in response to an electric field applied to the polymer; and a frame coupled to the at least two electrodes (15, 25) and the transparent elastic non-conductive material (20), the outer frame substantially preventing expansion in a second direction opposite said first direction in response to an electric field applied to the polymer.

    摘要: A system and method for controlling an entertainment system is provided. The system can have at least one light source to generate variable light output and at least one controller coupled to the at least one light source to control the variable light output based on a number of interruptions of power supplied to the apparatus over a pre-determined time period. The variable light output can be a light temperature. The at least one light source can be a plurality of light sources, with the at least one controller having a plurality of addresses and each of the addresses designating one or more of the plurality of light sources to be controlled. The at least one controller can synchronize or unsynchronize the plurality of light sources.
