  • Patent number: 6856351
    Abstract: A clamping circuit including a clamping diode, a bias line, and a clamp line is incorporated into a pixel circuit of amorphous silicon sensor arrays. The clamp diode in each pixel prevents the voltage across the photodiode from dropping below a specific threshold. By keeping the photodiode under reverse bias even under conditions that may otherwise saturate the pixel, image lag is reduced. In full fill factor amorphous silicon sensor arrays, a clamping circuit includes a clamp TFT, a bias plane, a clamp line, and a drain line. The clamp TFT reduces lag and blooming by draining off excess current developed under overexposure conditions. A method to globally reset a sensor array and a method to test and repair a TFT matrix in full fill factor sensor arrays without damaging the overlying collection electrode and sensor layer are also provided.

  • Patent number: 6856784
    Abstract: A belt fuser includes fuser and tension rollers rotatably supported in a frame. A belt reeved over the fuser and tension rollers holds at least two idler rollers in place and forms a nip with the fuser roller. The tension roller is connected to a tension control mechanism that applies, through the tension roller, a tension force in the belt and a normal force against the fuser roller throughout the nip. Because the belt holds the idler rollers in place, they can be of low-cost, light-weight, compact construction and require no additional support. Fusing nip length, dwell time, and thermal efficiency are greatly improved over two roll fusers, and the fusing temperature can be significantly reduced as a result. The belt fuser is more compact than previous belt fusers, occupying only slightly more space than conventional two roll fusers.

  • Patent number: 6853754
    Abstract: A compression and decompression system and process for optimally compressing and decompressing multibit per pixel image regions based on the type of data contained in the image region, e.g., whether the image region contains continuous tone data, including data to be halftoned, or non-continuous tone data, including antialiased text and lineart data. Segmented bytemap data blocks are processed to provide both low spatial resolution continuous tone data and high spatial resolution non-continuous tone data. However, the high spatial resolution non-continuous tone data is generated by quantizing and packing the high resolution bytes across an edge and discarding the high resolution bytes along the edge, i.e., the multibit data is discarded only in directions parallel to the edges of marks to be rendered in the image data. Additional information indicating the directions of the edges in the image data are stored to aid in decompression.
