Abstract: A training technique trains a neural network having sparsely-activated sub-networks. It does so by processing plural batches of training data in two respective passes of the neural network, yielding first prediction information and second prediction information. For each batch, the technique randomly assigns different sub-networks in the first and second passes of the neural network to process the batch. Over the course of training, the technique attempts to minimize loss information, which describes the difference between the first prediction information and ground-truth information, and the difference between the second prediction information and the ground-truth information. Simultaneously, the technique attempts to minimize divergence information, which describes the divergence of the first prediction information from the second prediction information (and vice versa).

Abstract: An ESD protection circuit includes a trigger transistor that is responsive to a detection signal indicating an ESD event. The trigger transistor pulls the voltage of a hold node towards a voltage of a power supply rail in response to the detection signal indicating an ESD event. The ESD protection circuit includes a replica trigger transistor whose leakage current controls current provided to the hold node after the detection signal no longer indicates an ESD event to compensate for leakage current through the trigger transistor.

Abstract: This disclosure relates to optical three-dimensional (3D) measurement, and more particularly to a large-depth-range 3D measurement method, system, and device based on phase fusion. Sinusoidal fringes corresponding to multiple high-frequency binary fringe patterns varying in stripe width, a middle-frequency binary fringe pattern, and a low-frequency binary fringe pattern are formed and then projected onto a to-be-measured object. After modulated by height of the object, the sinusoidal fringes are collected, and wrapped phases of the collected sinusoidal fringes are calculated to determine absolute phases of high-frequency sinusoidal fringes. Phase errors of a high-frequency sinusoidal fringe under different fringe widths are calculated according to the defocusing degree. An optimal absolute phase is selected based on the phase errors for the large-depth range 3D measurement.

Abstract: A structured light 3D measurement device and method based on defocus-degree-based unwrapping. Binary fringes varying in fringe width are projected onto an object, and a corresponding fringe image is collected by a camera, and then subjected to phase demodulation to calculate a wrapped phase. The defocus degree is calculated according to modulation degrees of the binary fringes. The defocus degree is plugged into the defocusing phase function to obtain a normalized reference phase. The wrapped phase is subjected to phase unwrapping based on the normalized reference phase to obtain an absolute phase to reconstruct a 3D point cloud.
