  • Patent number: 12240447
    Abstract: An object detection device includes first and second detectors each configured to detect an object by transmitting an ultrasonic wave in a moving direction of the moving object and receiving a reflected wave of the ultrasonic wave, a second detector, a memory, and a hardware processor coupled to the memory, and configured to: determine that an obstacle is present in the moving direction of the moving object, based on object detection results by the first and second detectors; determine crossing of the obstacle based on object detection results by the first and second detectors in a state in which it is being determined that the obstacle is present; and cause a driving controller mounted on the moving object, to release driving restriction control of restricting movement of the moving object when determining the crossing, or prohibit the driving controller from releasing the driving restriction control under a predetermined condition.

  • Patent number: 12208754
    Abstract: An in-vehicle network system includes a central ECU, which generates a control signal for a plurality of devices, and a plurality of zone ECUs, which relay a control signal from the central ECU. The plurality of devices include a first specific device (power window device, etc.), which is a device unrelated to drive control or the like of a vehicle, and which includes a sub controller (third signal processing unit, etc.) capable of activating an actuator based on an ON signal from at least one or some of the sensors. The first specific device is configured to control the actuator by using the sub controller in occurrence of abnormality of communication between the central ECU and the first specific device.

  • Patent number: 4340835
    Abstract: The present invention is directed to a tuning fork wherein a damping piece is provided, either integral with said tuning fork vibrator or a separate piece attached thereto, and wherein a damper member is intersected between said damping piece and a housing for accommodating the tuning fork vibrator.Since the (1/2)f.sub.O spurious response which is caused in the tuning fork vibrator to be spread within the damping piece is adapted to be absorbed by the damper member, the tuning fork is made smaller in shape.

  • Patent number: 4308481
    Abstract: A tuning fork resonator device includes a substrate having a recess formed in its one flat surface for receiving a damper made of an electrically conductive rubber and a metal leaf spring mounted on the substrate and being held in contact with the damper. A tuning fork is mounted on the damper through a support which is made of an electrical conductive material so as to electrically connect the tuning fork with the leaf spring.

  • Patent number: 4220885
    Abstract: A tuning fork wherein a tuning fork vibrator is supported on a damping member mounted in a housing and having such characteristics that it will cancel the (1/2)f.sub.0 of spurious response of the tuning fork vibrator without impeding the normal vibration of the tuning fork vibrator, whereby the size of the tuning fork can be minimized.

  • Patent number: 4178526
    Abstract: A tuning fork resonator which has a substantially U-shaped tuning fork supported in spaced relation to a support base by means of a support system with at least three support points. The three-point support system includes a pair of support rods holding the tuning fork therebetween and at least one electrode terminal pin supporting the tuning fork at one end face thereof. A piezoelectric transducer element provided for at least one of the opposed tines of the tuning fork is electrically connected to the terminal pin by means of an electroconductive elastic deposit of a bonding agent. An electrically insulating and shock and vibration absorbing layer is provided between the bottom of the tuning fork and the end face of the terminal pin which is held in contact therewith.
