  • Publication number: 20190353501
    Abstract: A detecting device obtains a first body motion signal from a body motion sensor while a person walks with a predetermined stride, the body motion sensor being attached to a body of the person and configured to detect a body motion of the person, obtains a reference-walk-waveform from a memory, the reference-walk-waveform being generated from a second body motion signal obtained from the body motion sensor while the person walks with the predetermined stride with the body motion sensor attached to an initially attached position, compares the obtained reference-walk-waveform with a waveform of the obtained first body motion signal to determine whether an attached position of the body motion sensor is shifted from the initially attached position, and outputs a determination result.

  • Publication number: 20190279006
    Abstract: An object recognition device installed on a vehicle includes a first camera detecting a first object, a second camera detecting a second object, a ranging sensor detecting a third object, and a controller. The controller sets first to third determination ranges with respect to detected positions of the first to third objects, respectively, and executes fusion processing by comparing the determination ranges. First and second pixel densities being pixel densities of the first and second objects are determined based on detected distances of the first and second objects, angles of view and numbers of pixels of the first and second cameras, respectively. The controller sets the first determination range larger as the first pixel density is lower, and sets the second determination range larger as the second pixel density is lower.

  • Patent number: 10375299
    Abstract: In an imaging device, a difference calculation unit calculates a differential signal between charge signals that have been accumulated and are held by first and charge holding units with different timings. A multiple sampling unit performs multiple sampling processing on the differential signal, and an analog digital conversion unit converts a signal that has undergone multiple sampling processing to a digital signal. That is, multiple sampling processing is performed on a differential signal with a higher sparsity than that of an image signal.

  • Publication number: 20190064829
    Abstract: A control device includes an electronic control unit executes steering control for avoiding a collision with an object that has a possibility of colliding with a host vehicle. The electronic control unit sets a timing when the host vehicle is predicted to pass the object as an end timing of the steering control when the steering control is performed. The electronic control unit determines whether or not a deviation possibility is present when the electronic control unit assumes that the steering control ends at the end timing. The deviation possibility is a possibility of the host vehicle deviating from a current traveling lane accompanying an end of the steering control. The electronic control unit performs reduction processing that reduces the deviation possibility when the electronic control unit determines that the deviation possibility is present.
