  • Patent number: 9912900
    Abstract: A display apparatus includes a first communication unit, a second communication unit, and a control unit that controls the first and second communication units. If the display apparatus is on standby in a first standby mode in which the first and second communication units are enabled, when the control unit receives a command via communication from an external device to the first communication unit, the control unit acquires information of another display apparatus via the second communication unit and transmits the information to the external device via the first communication unit. If the display apparatus is on standby in a second standby mode in which the second communication unit is enabled, when the control unit receives a command via communication from another display apparatus to the second communication unit, the control unit transmits information of the display apparatus to the other display apparatus via the second communication unit.

  • Patent number: 9488501
    Abstract: A measuring apparatus/method detects a signal varying with displacement of an object and measurement of the displacement. The apparatus includes clock generator, detector, operation device, and correction device. The clock generator generates, in synchronization with a request signal for requesting measurement data, a first clock signal having a cycle shorter than a cycle of the request signal. The detector performs the detection with respect to each cycle of the first clock signal. The operation device obtains the measurement data based on output of the detector. The correction device obtains a displacement amount of the object per unit time based on plural measurement data, and corrects the measurement data based on the obtained displacement amount and a time difference between the first clock signal relating to the measurement data and the first clock signal relating to the request signal. The method includes the corresponding steps of the apparatus.

  • Patent number: 9445961
    Abstract: A wheelchair table includes: an attachment part configured to be attached to a side part of a wheelchair; an arm supported by the attachment part; and a table body provided at a tip part of the arm. The arm is supported so as to be movable upward and downward relative to the attachment part such that the table body can be lowered from an in-use position located above a user's knees to a not in-use position located in front of and below the knees while the user sits in the wheelchair. With this wheelchair table, operability and safety during wheelchair travel can be enhanced while favorably maintaining the function as a table.
