    摘要： Systems and methods are provided for GF(q) iterative decoding. A decoder computes a plurality of R messages corresponding to a variable node of the decoder and forms decoder extrinsic information for the variable node by combining the plurality of R messages. The decoder stores the decoder extrinsic information in a memory during a first time period and retrieves the decoder extrinsic information from the memory during a second time period, the second time period occurring after the first time period. The decoder extrinsic information is provided to a soft detector.

    摘要： A user and test sample authentication system and method for identifying COVID-19 infected users is disclosed. An authentication platform receives a first user profile data from a first user device to register to an authentication service and generate a first scannable image. The platform receives a second user profile data from the second user device for registration and generates a second scannable image. A purchase order of a medical kit is placed to perform one or more diagnosis procedures on the first user to identify if the first user is infected by COVID-19. The diagnosis data is encoded to the first scannable image to form a unique corona ID. On scanning the unique ID, the diagnosis data and the user profile data are displayed, whereby the presence of coronavirus infection of the first user is determined before contacting one or more individuals to prevent spread of the disease or infection.

    摘要： A visual display system includes a first image source for producing a first image containing symbological information using a vector drawing system. A second image source produces a second image containing video, graphical, and/or symbology information with a brightness lower than the brightness of the first image. A light combining optical element combines the light from the first and the second image sources. An image forming optical system receives the combined light from the light combining optical element for forming a new image comprising a superimposition of the first image and the second image at a final image plane of the system. A light receiving element, located at the final image plane of the system, receives the new image from the image forming optical system and adjusts the characteristics of the light from the new image to generate a final image for direct or indirect viewing. The visual display system is particularly adaptable for use in a Heads-Up-Display (HUD) system.

    摘要： The present disclosure relates generally to data decoding, and more particularly to non-binary iterative decoders. Non-binary LDPC codes and LDPC decoders that may be used to decode non-binary LDPC codes are disclosed. Systems and methods are also disclosed that compute messages related to non-binary LDPC codes, in a LLRV form and in a metric vector form and to process these messages in non-binary LDPC decoders. Systems and methods are additionally disclosed that convert messages between the LLRV form and the metric vector form. The implementation and use of non-binary low density parity check code decoders, the computation of messages in the LLRV and metric vector forms, and the use of message conversion systems and methods, according to this disclosure, may provide increased information relating groups of codeword bits, increased computational efficiency, and improved application performance.

    摘要： After receiving a digital image, check if the digital image contains a predetermined object. If the digital image contains the predetermined object, extract object features from the predetermined object, then compare the object features with common features of each of the predetermined identifications. If the object features match the common features of one of the predetermined identifications, store the digital image into a database dedicated to the predetermined identification. If the object features do not match the common features of any of the predetermined identifications, register the predetermined object with a new identification. If the new identification is the same as one of the predetermined identifications, store the digital image into a database dedicated to the predetermined identification. If the new identification is different from all of the predetermined identifications, store the digital image into a database dedicated to the new identification.

    摘要： A known face guided imaging method applied for an electronic imaging device uses the scale of a known face sensed in a previous frame to define a scale range of a searching window, which adds a scale constraint into the searching window so as to search a current frame horizontally and vertically in the searching window to perform a face searching loop for a face. The invention simply sends a corresponding image patch within the scale range to a face detector for the face detection, and the searching space is constrained in a small group of scale ranges without the need of detecting the whole image of various different scales within the scale range, and thus the invention effectively reduces the huge quantity of computing values required for the detection process and greatly enhances the speed and efficiency of the face detection.
