Abstract:

A configurable cellular terminal engine (CTE) in accordance with an exemplary embodiment of this invention is configurable by an external agent (e.g., microcontroller, DSP, or state machine) to suit the particular requirements of different spread spectrum systems. In an exemplary embodiment, the CTE comprises on a chipset a modem unit and a channel codec unit. The modem unit has a front end unit for coupling to an antenna; a matched filter searchers unit coupled at least to the front end unit; a searchers unit coupled to at least the front end unit; a finger processing unit coupled to the front end unit; a parameter estimation processor unit coupled to at least the finger processing unit and the searchers unit; and a transmitter unit. The channel codec unit has a channel decoder unit coupled at least to the finger processing unit; and a channel encoder coupled at least to the transmitter unit.

Abstract:

A composite laser beam is swept as a pattern of scan lines on a projection surface, and selected pixels arranged along each scan line are illuminated to project an image of high quality and in color. A data frequency of a video signal supplied by a host is matched to a scan frequency of a scan mirror to reduce the amount of buffer memory required and to make the projected image brighter and more uniform in brightness.
