摘要： A method of zero-D dimming backlights for 3D or multi-view displays using right and left image data. The method receives right and left pixel luminance values for the right and left image data, and it remaps the right and left pixel luminance values using a factor based upon an average luminance value or based upon a luminance percentile value or a modified factor that further includes the absolute difference between left and right pixel luminance values. The factor or modified factor are selectively used to remap particular right and left pixel luminance values based upon a disparity consideration. The method results in power savings by dimming the backlight without perceptible or substantial loss in brightness of the display.

摘要： A solid state area light and spotlight having a solid state light source such as LEDs, tapered light guides, and external thermal guides. The area light includes a flared light guide, and the spotlight includes a light guide with a closed end. The light guides are coupled to the light source for receiving and distributing light from the light source with the distribution being based in part upon the shape and taper of the light guides. The thermal guide provides for thermal conduction from the light source and dissipating heat through convection and radiation for cooling the light.

摘要： A power harvester having a current transformer configured to be inductively coupled to a current conductor and a circuit for delivering power to a load. The transformer core has two sections joined together and separable from one another at interleaved portions, allowing the transformer to be installed around the current conductor. The circuit includes a rectifier coupled to the transformer and a transistor coupled in series between the rectifier and a load. The transistor receives an output current from the rectifier and provides power to the load. A resistor is coupled to the transistor and the load, and the transistor and resistor provide for limiting of the power to the load over a wide range of the conductor line currents.
