  • 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.

    Abstract: Methods and apparatuses for calibrating attitude-independent parameters of a 3-D magnetometer are provided. A calibration method includes storing and updating data related to a N×9 matrix T and a N×1 matrix U extended for each measurement with an additional row and an additional element, respectively, the additional row and the additional element being calculated based on values measured by the 3-D magnetometer for the respective measurement. The method further includes calculating analytically (1) a symmetric non-orthogonal 3×3 matrix D representing scaling and skew of the 3-D magnetometer measured values and (2) a vector b representing bias of the 3-D magnetometer measured values, using the stored data and a singular value decomposition (SVD) method.

  • Publication number: 20180017617
    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.

  • Patent number: 9307145
    Abstract: A video camera includes a first temperature sensor, a control logic circuit, a main system, a heating module, a fan and a power supply. After the power supply supplies power to the video camera, the first temperature sensor comes to be active, when the temperature sensed by the first temperature sensor is less than T1, the first temperature sensor outputs a control signal to the control logic circuit, which activates the heating module and the fan and prevents the power supply from supplying to the main system; and when the temperature sensed by the first temperature sensor is greater than T1, the first temperature sensor outputs a control signal to the control logic circuit which enables the power supply to supply to the main system and inactivates the heating module and the fan, and therefore, a normal activation and stable operation of the video camera at low temperatures are ensured.
