  • Patent number: 10563569
    Abstract: A diesel combustion system including a piston, an annular impinging block, and a combustion chamber. The combustion chamber is divided by the annular impinging block into an upper chamber and a lower chamber.

  • Patent number: 10393801
    Abstract: The present invention provides a method and a fault isolation system for detecting errors in an integrated circuit. One feature of the present invention is using a movable second probe to scan and acquire an output signal through the vias or metal line structure of a diagnostic area along a detecting line, so as to find the fault location precisely, and another feature of the present invention is using a cutter in conjunction with the above method to narrow down the fault range. The cutter is used to electrically isolate the portion of diagnostic area step by step for approaching the fault location. This method can help to save a lot of analysis time and also makes the minor fault localization possible.

  • Patent number: 10340990
    Abstract: A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords ci, where i is a unique codeword index for each codeword ci. Each codeword defines weighting factors to apply to the MIMO signals, and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets Si for each codeword ci of the codebook C. Each codeword subset Si defines L codewords cj, which are selected from all the codewords ci in the codebook C. The codewords cj in a codeword subset Si are the L codewords in the entire codebook that best correlate with the corresponding codeword ci.
