  • Patent number: 11009942
    Abstract: The invention discloses a multi-human tracking system and method with single Kinect for supporting mobile virtual reality applications. The system can complete the real-time tracking of users occluded in different degrees with a single Kinect capture device to ensure smooth and immersive experience of players. The method utilizes the principle that the user's shadow is not occluded when the user is occluded under certain lighting conditions, and converts the calculation of the motion of the occluded user into a problem of solving the movement of the user's shadow, and can accurately detect the position of each user, rather than just predicting the user's position, thereby actually realizing tracking.

  • Patent number: 10930532
    Abstract: An object detection system utilizes a teach cycle performed with a low-pressure blow-off (i.e. positive pressure) instead of vacuum (negative pressure). During the teach operation, the positive pressure is enabled and the nozzle is lowered to the object. An air sensor detects pressure or flow at the nozzle tip. A rise in pressure or drop in flow is detected as the nozzle makes contact with the object (i.e. just before or just after actual physical contact is made). The height of the object is stored as the taught height to be used subsequently in repetitive operations by the machine. This teaching method is particularly useful for very small objects because the positive pressure does not lift the object.

  • Patent number: 10914858
    Abstract: A system and method of correcting induction logging data for relative dip, wherein an induction logging tool is utilized to collect initial induction logging data at a plurality of frequencies. The initial induction logging data is then corrected for skin effect and borehole effect, after which, inversion is performed on the processed induction logging data to determine a dip effect correction. The dip effect correction is then applied to the initial induction logging data in order to yield induction logging data that is dip corrected to reflect a zero relative dip. Once dip corrected, the induction logging data can be used with resistivity methodologies generally designed for instances where no dip is present in the formation under analysis. In certain embodiments, the inversion step utilizes an additive correction for the dip effect correction.

  • Patent number: 10912495
    Abstract: A variety of techniques are used automate the collection and classification of workout data gathered by a wearable physiological monitor. The classification process is staged in order to correctly and efficiently characterize a workout type. Initially, a generalized workout event is detected using motion and heart rate data. Then a location of the monitor on a user is determined. An artificial intelligence engine can then be conditionally applied (if a workout is occurring and a suitable device location is detected) to identify the type of workout. In addition to improved speed and accuracy, a workout detection process implemented in this manner can be realized with a sufficiently small computational footprint for deployment on a wearable physiological monitor.
