  • Patent number: 10721674
    Abstract: An information processing apparatus which is capable of identifying an exact distance to a transmitting apparatus. A received radio wave intensity is measured when a radio wave transmitted from a transmitting apparatus via a short-range wireless communication is received, and a distance to the transmitting apparatus is identified based on a distance management table in which the received radio wave intensity and a distance associated with the received radio wave intensity are managed. A received radio wave intensity at a reference position a predetermined distance away from the transmitting apparatus is measured. The distance management table is calibrated based on the measured received radio wave intensity at the reference position.

  • Patent number: 10718864
    Abstract: A radar device includes a signal processing unit and a target information output unit. The target information output unit outputs only pair data having addition reliability equal to or larger than a threshold to the outside of the radar device as target information. The signal processing unit determines whether a first target and a second target belong to the same object. The first target is pair data derived later than the second target. If it is determined that the first target and the second target belong to the same object, the signal processing unit transfers reliability of the second target to the first target.
