  • Patent number: 11243094
    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.

  • Patent number: 10922561
    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.
