Abstract: Pixels for a large video display which employs solid-state emitters, such as colored light emitting diodes, as light source are formed by outfitting each colored solid state emitter within the pixel with an individually tailored miniature intensity-enhancing optical system. Each of these miniature optical systems comprises a set of four wide field-of-view Lambertian reflectors (34), a pair of narrow field-of-view Lambertian reflectors (36), and a beam-shaping lens (38). The miniature intensity-enhancing optical system can be specifically designed to restrict emission in the vertical field-of-view, while providing a Lambertian intensity dependence throughout an unrestricted horizontal view. For example, the field-of-view in the vertical direction may be limited to about ~ 30° while the field-of-view is about ~ 90° in the horizontal direction.

Granted: 2007-03-20
Abstract: A battery charger includes line-level input rectification, a high-frequency oscillator-controlled chopper circuit, multiple transformers operating in parallel, and controlled output rectification. Ilse of line-level input rectification reorders the elements of the battery charger compared to previous designs. A chopper frequency several orders of magnitude higher than that of the AC power mains is used. The use of multiple, parallel-wired transformers for voltage and current transformation eases constraints on the physical geometry of a manufactured battery charger product by permitting individual transformers, each smaller than a comparable single transformer, to be employed. Controlled output rectifiers permit power levels to be regulated dynamically.
