Abstract: A shaft voltage reduction structure is mounted on an electric machine having a bearing house and a rotor shaft rotatably connected together, and includes an electrically conductive main body, at least one electrically conductive bearing, and an electrically conductive shaft. The conductive main body is mounted to a bottom of the bearing house and includes a conductive shaft barrel projected from a center thereof.

Abstract: An adjustable-focus PV (picture/video) camera in a mixed-reality head-mounted display (HMD) device operates with an auto-focus subsystem that is configured to be triggered based on location and motion of a user's hands to reduce the occurrence of auto-focus hunting during camera operations. The HMD device is equipped with a depth sensor that is configured to capture depth data from the surrounding physical environment to detect and track the user's hand location, movements, and gestures in three-dimensions. The hand tracking data from the depth sensor may be assessed to determine hand characteristics—such as which of the user's hands or part of a hand is detected, its size, motion, speed, etc.—within a particular region of interest (ROI) in the field of view of the PV camera. The auto-focus subsystem uses the assessed hand characteristics as an input to control auto-focus of the PV camera to reduce auto-focus hunting occurrences.

Abstract: The present disclosure provides a device and methods for determining the original stratum direction of a core. The device includes a confining pressure pump, a resistance meter, and a core holder composed of upper and lower portions. The present disclosure further provides three methods for determining the original stratum direction of the core. The three methods respectively use the device to measure resistance values at different positions of the core, and compare a test result with an imaging result of resistivity imaging logging data to determine the rock direction of the core in a stratum.

Abstract: An ESD protection circuit includes at least two unidirectional conduction units arranged between an IO node of an integrated circuit and a positive voltage node, where a first connection node is between the at least two unidirectional conduction units; at least two unidirectional conduction units arranged between the IO node and a negative voltage node, where a second connection node is between the at least two unidirectional conduction units; and a voltage tracking circuit. The input of the voltage tracking circuit is electrically connected to the IO node and the output of the voltage tracking circuit is electrically connected to at least one of the first connection end and the second connection end. By reducing the voltage difference between the IO node and the first connection end or between the IO node and the second connection end, the parasite capacitance associated with the unidirectional conduction unit can be reduced.

Abstract: According to the present invention, a probe beam (14) having undergone dispersive Fourier transformation by a dispersive Fourier transformation unit is spatially mapped, an inspection object (18, 20) is irradiated with the probe beam (14), and transmitted light (15) from the inspection object (18, 20) is detected, whereby an image is generated on the basis of the intensity of the transmitted light (15).

Accordingly, access of the drivers to the respective hardware components may be granted serially, even though the drivers have been loaded in parallel.
