  • Patent number: 10558175
    Abstract: A technique capable of shortening a period in which value of a PID parameter is outside of an appropriate range is provided. A measured value acquisition functional unit processes a sensing signal of a sensor that measures a barrel and acquires a measured value of the barrel. A storage unit stores a target value of the barrel and a PID parameter. An operation amount calculation functional unit calculates an amount of operation using the PID parameter and a difference between the measured value and the target value. A first output unit and a second output unit output the amount of operation. A first updating functional unit updates the PID parameter through a first update process when the variation range is greater than a first range, and a second updating functional unit updates the PID parameter through a second update process when the variation range is less than a second range.

  • Patent number: 10546380
    Abstract: A calibration device acquires an image of an imaging target located ahead of a vehicle. Images of the imaging targets behind the vehicle are acquired, which are different from the acquired images captured in the forward direction. The shape and size of the imaging targets are already known. The calibration device performs projective transformation for the imaging targets shown in overlap regions of the acquired images, and identifies a roll, a pitch and a vertical position of each camera such that the conversion results are in agreement with the shape and size of the targets. The calibration device identifies an x-coordinate, a y-coordinate, and a yaw of each camera such that one link angle in a virtual link structure is minimized.

  • Patent number: 10542199
    Abstract: An image capture apparatus includes an image capture unit, a communication unit, and a control unit which communicates with an external device by first or second communication systems. The first system maintains communication connection even if the apparatus and device are not in a predetermined operational mode for executing image transmission processing. The second system maintains communication connection if the apparatus and device are in the predetermined mode. The control unit can automatically transmit a photographed image to an external device through the communication unit by the second communication system, and switch and control first and second functional modes for enabling and disabling a photography function, respectively. Where an image is photographed in the first mode, the control unit records the image as a target for automatic transmission. If the transmission target image is recorded, automatic transmission is not started during the first mode, and started during the second mode.

  • Patent number: 10522929
    Abstract: In a connector, a terminal has a pair of contact portions that are fixed to a housing and disposed so as to provide a stable and reliable electrical connection. In the connector, a movable housing has a first contact portion fixation groove that supports a first contact portion of the terminal and a second contact portion fixation groove that supports a second contact portion. The terminal has a link portion that can join the first contact portion and the second contact portion to each other so as to be able to adjust the clearance therebetween. The link portion can absorb a variation in the clearance between the first contact portion fixation groove and the second contact portion fixation groove and a variation in the clearance between the first contact portion and the second contact portion.
