  • Publication number: 20190246731
    Abstract: A principal objective of the present invention is to provide system for temperately retaining eyeglasses on a user's headwear. This objective is achieved by incorporating magnetic elements on the headwear and eyewear of the user. In one embodiment of the present invention, two magnetic elements are attached to the inside surfaces of the two temple arms of a pair of eyeglasses. Another two magnetic elements are attached to the two sides of a hat permanently or removably. The polarities of the magnetic elements are arranged in such way that when the two temple arms of the eyeglasses are placed in contact to the two sides of the hat from the outside of the hat, the magnetic elements on the eyeglasses and the magnetic elements on the headwear form magnetic element coupling pairs with attraction magnetic force. When the eyeglasses are not in use and need to be temporarily stored away from the eyes, the user can lift them to the crown or above the brim of the hat.

  • Publication number: 20190253015
    Abstract: A space vector pulse width modulation (SVPWM) method for suppressing a common-mode voltage of a multiphase motor includes the following steps: (1) dividing all basic vectors of the multiphase motor into q types, and selecting therefrom x types having equal common-mode voltage magnitude of which an absolute value is smallest; (2) for each type in the x types of basic vectors, structuring y classes of auxiliary vectors according to an optimization model; (3) synthesizing reference vectors by virtue of the auxiliary vectors to obtain functioning time of basic vectors functioning in each switching period; and (4) obtaining an optimal functioning sequence of the basic vectors functioning in each switching period with fewest switching operations of a converter as a purpose.

  • Publication number: 20190238159
    Abstract: A method to explicitly indicate the version information while still supporting soft combining is disclosed. A polar code encoder maps q bits to q positions of q sub-channels, q is a positive integer; wherein the q bits are used to indicate a version of encoded codeword; map 1 to a special frozen bit corresponding to the q bits; map K?q information bits to K?q positions for the K?q information bits, K is an integer, K>q; and perform polar encoding over an input vector u0N?1, comprising the q bits, the special frozen bit and the K?q information bits, with the length of N, N is an integer, N>=K. With this method, there is no need to make blind detection to achieve the version information of transmitted payload, which reduces power consumption for a receiver.

  • Publication number: 20190173640
    Abstract: A transmitter has a transmit chain that is configured to format transmit data into a frame structure that comprises signal blocks interspersed with training sequences for assisting a receive operation. The transmit chain is configured to insert two training sequences between a signal block and its following signal block in the frame structure. The transmitter also comprises a sequence generator configured to form the two training sequences, and in particular to form them such that a first of the training sequences is a negative of the second. Having one training sequence being the negative of the other helps to avoid the Direct Current (DC) subcarrier and provides good properties for channel estimation.
