This is about a new scheme for driving reflective bistable cholesteric displays (BCDs). It relies on fast switching from the planar state to the focal conic (FC) state, the two stable states in BCDs. The new scheme allows BCDs be driven using simpler electrical wave forms, and also making line add.....

A laser interferometer system can be used to measure the straightness of an object. A typical Hewlett-Packard's straightness interferometer system uses a Wollaston prism to split a laser beam traveling along a principal axis into two secondary beams. However, the resolution and the range of the resp.....

Previous merging algorithms have un-practically high computational complexity and hence cannot be applied to medium or large size networks. This invention presents two fast algorithms to merge anonymous routers. The first one uses Isomap to embed routers into a high-dimensional space based on their .....

Display is a large and still continuously expanding market. Flat-panel display is the dominating segment in the industry which involves the use of active-matrix driving technology. In conventional active matrix displays, thin film transistors (TFTs) are formed by amorphous silicon (a-Si). However, i.....

Portable electronic devices such as laptop computers, personal digital assistants, and portable DVD players and the like have become increasingly common and popular. One reason for the success of such devices is the advance in the technology of low power, lightweight and inexpensive flat-panel displ.....
