  • Patent number: 11827449
    Abstract: A mover according to the present disclosure includes: a body to move; a second member; a suction unit; a location detection unit; a first moving part, and a second moving part. The second member moves in a state where the second member is combined with a first member provided for an object, as the body is displaced relative to the object. The suction unit is sucked to the object in the state where the second member is combined with the first member. The location detection unit detects a location of the body with respect to the object by detecting movement of the second member. The first moving part moves the body until the state where the second member is combined with the first member is established. The second moving part displaces the body relative to the object in the state where the second member is combined with the first member.

  • Patent number: 11370398
    Abstract: Disclosed herein is a mover including a plurality of wheels, a body, and a friction braking mechanism. The body has a bottom surface. The body is supported by the plurality of wheels with the bottom surface facing a traveling surface, and travels on the traveling surface by turning the plurality of wheels. The friction braking mechanism applies a brake on the body with at least a portion of the bottom surface or at least a portion of a movable body brought into contact with the traveling surface by switching, while the body is traveling, a state of the movable body from a first state into a second state. The second state is a state where the movable body protrudes from the bottom surface to a different height from in the first state.

  • Patent number: 11320831
    Abstract: Disclosed herein is a mover including an object detecting unit and either a masking processing unit or a transmission restricting unit as an additional processing unit. The object detecting unit detects an object based on a reception signal output from a receiver unit by having a transmitter unit transmit a scanning wave and by having the receiver unit receive a reflected wave, which is a component, reflected from the object, of the scanning wave. The masking processing unit performs masking processing of masking, in accordance with a timing at which, and/or a direction of incidence in which, a disturbance wave, not depending on the scanning wave, is incident on the receiver unit, a portion of the reception signal output from the receiver unit. The transmission restricting unit restricts a transmission range in which the transmitter unit transmits the scanning wave.

  • Patent number: 8890778
    Abstract: A display device includes an organic EL element and a capacitor. A driving transistor is connected to an anode of the organic EL element and passes a current to the organic EL element. The current corresponds to a voltage held in the capacitor. A first switch is between the capacitor and a data line, and the data line supplies the voltage to the capacitor. A voltage detector is connected to the data line for detecting an anode voltage applied to the organic EL element. A second switch is between the anode and the data line. A controller turns on the first switch, causes the organic EL element to emit light, and causes the voltage detector to detect the anode voltage by turning off the first switch and turning on the second switch while the organic EL element is emitting light.

  • Patent number: 8860705
    Abstract: An image display device includes a luminescent panel in which luminescent pixels are two-dimensionally arranged. Each luminescent pixel has a stacked luminescent layer and driving layer. The driving layer includes a capacitive element that includes two electrode layers stacked in parallel. A memory stores coordinate information of a repaired luminescent pixel in which the capacitive element is repaired through disconnection of a part of one of the two electrode layers. A controller converts video signals received by the image display device into luminescent pixel signals that determine luminescence of the luminescent pixels. The controller outputs the luminescent pixel signals to a driver in a scanning order.

  • Patent number: 8736638
    Abstract: The present invention provides an organic light emitting display device in which light emitted by an OLED whose luminance is adjusted for detection of deterioration does not stand out as compared to light emitted by other OLEDs, thereby not producing an unpleasant sensation for users. A calculation unit in a display control unit 104 sets, for a target pixel 302, a driving signal Out(C)=V. For a peripheral pixel 301 horizontally located immediately before the target pixel 302, the calculation unit calculates a driving signal Out(C?1)=In(C?1)?V(In(C))/2. For a peripheral pixel 303 horizontally located immediately after the target pixel 302, the calculation unit calculates a driving signal Out(C+1)=In(C+1)?V(In(C))/2.
