摘要： An image processing method and system is provided for reducing the quantization layer in an input quantized image. The system detects if a pixel in a quantized input image belongs to a ramp area in a selected direction. Based on such ramp detection, a quantization level is dynamically selected. Then, a pre-segmentation operation is performed on a smoothly changing image area for each pixel in that direction. That area can then be refined by segmentation. A low-pass filtering process can then be applied to the refined segment to obtain filtered pixels. An overall gain value is then determined and used to adjust the filtered pixel luminance values to obtain output luminance values with higher precision values than that of the input image luminance values. This provides an output video image with reduced quantization layer and less perceivable quantization artifacts.

摘要： An example-based method and system for electronic display color calibration is provided. By comparing the colors of commonly available objects with a color database under a controlled lighting condition, the user adjusts the gain and offset parameters of the Red, Green and Blue color components of the display. Two different methods are provided, wherein one method involves manipulating the comparison colors in the RGB color space, and the other method involves manipulating the comparison colors in the CIE x-y plane. Two different systems that incorporate the example-based color calibration methods are also provided, wherein one system directly implements the calibration method in the television system, while the other system implements the calibration method as a separate tool for viewers to calibrate the color of their displays.

摘要： Mass handling methods for the continuous processing of masa type dough in conjunction with commonly available feed processing equipment, such as a masa extruder, an oven, or cooling apparatus. One masa handling method includes a masa separator having a pair of opposed, endless belt conveyors having facing surfaces spaced apart to receive a generally continuous masa stream output from a nozzle on the masa extruder. When the masa stream moves between the conveyors, it is gripped by their facing surfaces and moved away from the nozzle, causing the masa to be separated into individual pieces, or logs. The masa handling method can also include feeding the masa to masa hoppers fed by at least two endless belt conveyors arranged in upstream and downstream positions relative to each other. The masa is transported along the conveyors and is automatically diverted into one masa hopper by a diverter gate operated by a controller that receives a signal from a sensor sensing a masa level within an associated one of the hoppers. The hopper has one or more rotating shafts having projections to remove gas bubbles from the masa and force it toward the sheeter rollers. A pair of primary rollers with scrapers can be provided within the hopper to roll the masa to an intermediate thickness before it passes between the sheeter rollers.

摘要： A localization process in a network of source devices and sink devices on a 1394 bus, is performed by a source device while it is communicating to a sink device, which determines local network links from nonlocal ones. An actual round trip time calculation is performed only by the source device and the sink device can be relatively passive. The duties of the sink device are performed in hardware and involve (trivially) modifying the received message while moving the message from the input isochronous channel buffer to the output isochronous channel buffer.

摘要： A dual function binding machine for making journal notebooks at home includes a hole punching mechanism and a binding mechanism. A punch die includes a plurality of rectangular punch teeth in a graduated configuration to minimize the amount of force required to penetrate through the journal book materials. A guide provides different positions for punching through covers, inner pages and continuous punching of both. This allows the perfect alignment and fit of the outside covers with the inside pages. A spring biased lever operates the punch die in a horizontal direction. The binding mechanism included in the same machine has a vertical outer vise wall that is horizontally movable to compress the binding material to the pages and covers of the journal notebook.

摘要： Improved LDPC code structure and concatenation rules for IEEE 802.11n systems, providing two code sets per rate, one longer codeword and one shorter codeword. The longer codeword length is determined by the system parameters, while the shorter codeword length is ⅓ of the longer codeword length. A LDPC concatenation rule is provided, wherein a maximum of one extra OFDM symbol is added in padding in order to reduce the code set granularity. In order to provide improved code performance, more bits are shortened compared with puncturing, by transmitting the extra OFDM symbol. Further, all the required puncturing and shortening bits are distributed across all codewords. This scheme provides a preferred tradeoff between code complexity and over-the-air efficiency.
