摘要： A method and a system for displaying images are provided. In the method, a pixel is provided that includes a layer of ferroelectric material and a layer of liquid crystal material. A first electric field is momentarily applied to the pixel to electrically polarize the ferroelectric layer to a first polarization. The first polarization is then used to maintain the liquid crystal material in a first orientation corresponding to a first apparent brightness of the pixel.

摘要： Optical motion sensing systems and methods are described. In one aspect, light from subfields of a scene is focused onto respective capture areas of a focal plane. Successive sets of contemporaneous local images are captured from the focused light. Respective saliency measures are derived from respective ones of the local images. Respective local motion measures are determined from comparisons of corresponding ones of the local images in ones of the contemporaneous local image sets. A respective global motion measure is produced for each of the contemporaneous local image sets based on the respective ones of the local motion measures and the respective ones of the saliency measures.

摘要： An enhanced light output light emitting diode (LED) is constructed using a plurality of single domed LEDs with each dome acting as a lens. By packaging multiple LEDs, each with its own dome (lens), greater-light output can be achieved. In one embodiment, each individually domed LED is a single color and the mixed colors from the group of LEDs within a device yields white light output. In another embodiment, the phosphors within each dome are mixed to produce white light. Reflectors can be added to enhance light output.

摘要： A wavelength selective switching device and method for selectively transmitting optical signals based on wavelength utilizes diffraction to spatially separate the optical signals of different wavelengths such that the optical signal of a selected wavelength can be selectively transmitted. The wavelength selective switching device selectively rotates the polarization components of the optical signals such that the polarization states of the polarization components are the same in both incoming and outgoing directions at the diffraction grating. Thus, a diffraction grating with a high grating line frequency (e.g. greater than 900 grating lines per mm for signals in the 1550 nm wavelength range) can be used for diffracting the polarization components of the optical signals in both the incoming and outgoing directions.
