  • Patent number: 10817007
    Abstract: A pre-driver circuit generates a driver bias signal based on a swing command, a driver impedance characteristic, and an input signal. A driver receives the driver bias signal and generates, in response, a driver signal having a swing and having an output impedance corresponding to the bias signal. Optionally, the driver receives power from a switchable one of multiple supply rails, according to the swing. Optionally, the driver has voltage controlled resistor elements and the driver bias signal is generated based on the swing command and a replica of the driver voltage controlled resistor elements.

  • Publication number: 20200199698
    Abstract: The disclosure discloses a method for reinforcing a rail by laser and auxiliary heat source efficient hybrid cladding. The laser and the auxiliary heat source simultaneously apply on a region to be cladded of a rail surface. The laser serves as a main heat source to enable simultaneous and rapid fusion of an added metal powder and partial substrate material in the rail surface to form a molten pool. The auxiliary heat source moves with the laser heat source in the same direction at the same speed, and performs synchronous preheating and/or post-heating on the laser molten pool, the heat-affected zone and the surface layer of the rail substrate to reduce the temperature gradient, thereby reducing the cooling rate, and avoiding martensite transformation and cracking in the heat-affected zone.

    Abstract: A glove for use in collecting data for sign language recognition comprises: multiple azimuth sensors arranged on the glove at positions corresponding to the phalanges and metacarpal bones of the hand and used for sensing postures of the hand. The azimuth sensors are only arranged on the glove at positions corresponding to the phalanges of the hand other than the distal phalange in proximity to the fingertip of at least one finger among the middle finger, the index finger, the ring finger, and the little finger. The glove reduces the number of the azimuth sensors arranged on the glove at positions corresponding to the phalanges of the hand, thus reducing costs while not affecting detection performance.
