Abstract: An image scanning device contains a contact image sensor. The contact image sensor comprises at least a light source, a columnar lens, and a sensor. The light source consists of a plurality of light emitting diode and a light guide. Light emitting diodes are placed uniformly along the long side of the rectangular light guide such that the incident light after total internal reflection emits directly from the other long side of light guide. The light guide requires neither specially processed diffusion surface nor diffusion layer covering. The columnar lens is placed in a light path after light is reflected by the document being scanned and focuses the light beam. The image sensor is placed below the columnar lens to receive the focused reflected light and processes received signal by a subsequent circuit. Accordingly, the contact image sensor of the present invention has an uniformly illuminating linear light source and a reduced manufacturing cost.

Title: Implementation of opportunistic data on a statistical multiplexing encoder
Inventor: WU SIU-WAI
IPC: H04J3/24
Filed: 2000-06-30
Granted: 2002-02-11
Abstract: A method and apparatus for providing an opportunistic data capability for an existing statistical multiplexing encoder platform, such as a multi-channel video data encoder. An opportunistic data processor (ODP) is provided as a plug-in card or an external device that can be interfaced with an existing multi-channel encoder. The ODP communicates with a quantization level processor (QLP) and packet multiplexer (PM) in the multi-channel encoder as if it was just another channel encoder. The ODP implements a special rate control scheme by encoding data and sending it to the PM only when a global quantization level (QL) indicates that spare bandwidth is available. Spare bandwidth is assumed to be available when the global QL is less than a threshold value. Moreover, the OPD sends a bandwidth need parameter to the QLP, as do the other channel encoders. However, the ODP's need parameter is scaled by a function of the global QL to attenuate its actual bandwidth need as the global QL increases to provide smooth variations in the ODP's encoded data rate.
