  • Patent number: 10341726
    Abstract: According to one embodiment, a video sender comprises: a video processor and a communication module. The video processor creates video. The communication module is configured to communicate with a video receiver. The communication module comprises: a receiver and a transmitter. The receiver receives, from the video receiver, specific information specifying which one of a color signal and a frame rate takes precedence over the other one in transmission. The transmitter converts the video created by the video processor into video in which one of the color signal and the frame rate takes precedence over the other one in accordance with the specific information, and transmit the video thus converted to the video receiver.

  • Publication number: 20180145436
    Abstract: To prevent damage from being caused in a movable piece caused by inclination of the movable housing of a floating connector. Providing an inclined piece portion in a movable piece of a plug terminal of a plug connector from a middle side to an outer edge side of a bottom wall portion of a movable housing, the inclined piece portion obliquely extending so as to gradually be distanced away form a substrate. Since the inclined piece portion is distanced away from the substrate by the amount of inclination of the inclined piece portion when the movable housing is inclined, a risk of the movable piece impinging against the substrate can be reduced.

  • Publication number: 20170373882
    Abstract: According to one embodiment, an adapter apparatus includes a first connector conforming to the first standard, a second connector conforming to the second standard, a first transmitter and circuitry. The first transmitter transmits a first signal to a first external apparatus connected via the first connector. The first signal associates with a request to determine whether a first mode is supported by the first external apparatus. The first mode corresponds to a communication mode that conforms to a second standard via the first connector. The circuitry generates a second signal when the first external apparatus does not support the first mode. The second signal is used to make an indication representing that the first external apparatus does not support the first mode.

  • Patent number: 9590543
    Abstract: The purpose of the present invention is to reduce noise by controlling vibration due to rotation fluctuation, and to consume only current required for maintaining the rotation by bringing the current for driving a motor closer to a state of synchronization. A drive means drives a sensorless brushless DC motor by switching an energization pattern at a constant frequency to determine the rotation position of the rotor of the sensorless brushless DC motor. A detection means detects a zero-cross signal representing the switching of the phase of the rotor. A calculation means calculates a synchronization determination rate representing a percentage of the number of detected zero-cross signals. A pulse width control means controls the pulse width of a PWM drive duty in the drive means so that the calculated synchronization determination rate falls within a target range.
