  • Patent number: 10656265
    Abstract: A mining work machine includes an obstacle determination device connected to a periphery detection device. If measurement points detected by the periphery detection device in a current cycle are equal to or greater than predetermined size thresholds equivalent in size to the mining work machine, these measurement points are put into a single obstacle candidate group. Based on relative speeds of the obstacle candidate at the measurement points and a traveling speed of the mining work machine, it is determined whether the obstacle candidate is a stationary object or a moving object, and whether the stationary object has been also detected by the periphery detection device in a preceding cycle. If a position of detection of the stationary object detected for the first time is equal to or smaller than a non-obstacle determination distance threshold, the obstacle determination device outputs the obstacle candidate as a non-obstacle.

  • Patent number: 10649084
    Abstract: An object detection apparatus measures a distance to a detected object at each irradiation angle, based on reflected waves of electromagnetic waves irradiated from a laser light irradiating unit at each irradiation angle. The apparatus determines whether the measured distance remains unchanged for prescribed period of time, for each irradiation angle, and stores the determined distance in a storage unit as a stationary object distance in association with the irradiation angle. The apparatus compares the current measured distance and the stored distances, and determines whether a stationary object distance matching the current distance is present among the stored distances.

  • Patent number: 10641905
    Abstract: Techniques are provided for determining a moving body's position and velocity in the presence of motion of a measuring device relative to the body. For example, a swimmer's position and velocity may be determined by compensating for bias that may result from a swimmer's arm swing. This may help avoid over-estimating a swimmer's velocity that results in inaccurate position estimation along the swimmer's path. To compensate for the swimmer's arm swing, an estimate of translational velocity due to arm rotation may be removed, e.g., from pseudo-range rates (PRRs) from satellite positioning system measurements, to reduce the systematic bias errors. A scale factor is applied to an estimated velocity of the swimmer's body to estimate the velocity of a mobile device on the swimmer's wrist, e.g., while above water.
