摘要： A decoding system including a low density parity check (LDPC) processing module and a termination module. The LDPC processing module is configured to receive a test codeword based on a codeword received over a communications channel, and perform, for each row of a parity check matrix, a processing operation on the test codeword. The LDPC processing module is configured to, once the processing operations have been performed for all the rows, repeat the processing operations. The termination module is configured to monitor progress of the LDPC processing module and selectively generate a termination signal in response to the test codeword being a valid codeword according to the parity check matrix. The LDPC processing module is further configured to terminate the processing operations in response to generation of the termination signal.

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： 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.
