  • Patent number: 11285876
    Abstract: An attachment structure includes a support part for an in-vehicle device, a plate spring attached to the support part, and a screw screwed into the support part. The attachment base slides and is received in a space interposed between left and right plate spring pieces. The screw is fastened in this state. A screw distal end presses a front surface of the attachment base to generate an appropriate force of fitting between the attachment base and the left and right plate spring pieces and thereby the attachment base and the plate spring are elastically fitted with each other. The in-vehicle device is attached to the attachment base via the plate spring using the elastic fitting. If an external force that is equal to or exceeds a predetermined value is applied to the in-vehicle device, the elastic fitting is cancelled and the in-vehicle device drops off from the attachment base.

  • Publication number: 20220073000
    Abstract: A tilting mechanism of a view device for a vehicle has a configuration in which a rotating section is rotatably supported on a shaft of a fixed portion. A helical compression spring is fitted onto the shaft. A plate is attached to the free-end side of the shaft via a washer. An outer circumferential surface of the shaft and a center hole of the washer include respective different diameter portions. A gap g in a radial direction is formed between the outer circumferential surface of the shaft and an inner circumferential surface of the center hole of the washer. The tilting mechanism includes a deviation mechanism. The deviation mechanism makes the gap g become narrow or zero at the different diameter portions at at least one place, the different diameter portions facing each other, by making the washer move relative to the shaft in the radial direction.

  • Patent number: 11232540
    Abstract: With respect to two images acquired from two video images including a mutually-overlapping area in which the two video images overlap each other, an image transformation matrix for mapping coordinate systems is sequentially generated. Coordinate transformation of at least one image of the images is performed using the generated image transformation matrix. A composite image is created by overlaying two images with the at least one image subjected to the coordinate transformation. The currently used image transformation matrix and the newly generated image transformation matrix are compared with each other. If the two image transformation matrices are similar, the coordinate transformation is performed using the currently used image transformation matrix continuously. If the two image transformation matrices are dissimilar, the coordinate transformation is performed using an image transformation matrix corrected with the newly generated image transformation matrix.

  • Patent number: 11131872
    Abstract: A mirror display apparatus that subjects a mirror optical element to pulse voltage driving so that a reflectivity in a mirror mode can be changed by means of a duty cycle of the pulse voltage is provided. A mirror display apparatus includes a monitor display device and a mirror optical element disposed on the front side of the monitor display device. The mirror optical element includes a liquid-crystal panel with a reflection-type polarizer disposed on the back side thereof. The mirror optical element has a reflectivity and a transmissivity that are changed in respective directions opposite to each other via electric driving using a voltage applied to the liquid-crystal panel. A control circuit drives the liquid-crystal panel using a pulse voltage and performs control to change the reflectivity and the transmissivity of the mirror optical element by changing a duty cycle of the pulse voltage.

  • Publication number: 20210244287
    Abstract: The accuracy of detection of a heartbeat is increased and a time for detection of a heartbeat is shortened. A heartbeat detection device includes a heartbeat detection unit which detects a heart rate using the luminance of captured images of a part of a body surface of a user, which are captured images of a plurality of frames which have been captured in chronological order. The heartbeat detection unit computes a total luminance of the captured image of each of the frames, delays a vibrating wave representing chronological change of the total luminance at certain time intervals, and computes the heart rate using a cycle of a peak at which a difference between the vibrating wave which has not been subjected to a delay and each vibrating wave which has been subjected to a delay is reduced in a waveform of the difference.

  • Patent number: 11056830
    Abstract: A manual operation element includes a locking active surface and an unlocking active surface. A locking displaceable element includes a locking passive surface and an unlocking passive surface. When the manual operation element is operated in a locking direction, the locking active surface engages with the locking passive surface and displaces the locking displaceable element toward a locked position. When the manual operation element is operated in an unlocking direction, the unlocking active surface engages with the unlocking passive surface and displaces the locking displaceable element toward an unlocked position. When the locking displaceable element performs a displacement operation electrically, neither the locking active surface and the locking passive surface nor the unlocking active surface and the unlocking passive surface engage with each other in an entire area or more than half area of a displacement range of the locking displaceable element.
