Abstract: Disclosed embodiments include: (A) obtaining a plurality of camera views from a plurality of cameras configured to obtain frames of video data containing persons within an environment; (B) for each camera view, (i) detecting persons within the camera view by processing the video data from the individual camera via a neural network, and (ii) generating a bounding box for each detected person; (C) generating sets of associated bounding boxes, each set includes multiple bounding boxes from multiple different camera views that correspond to the same detected person; and (D) for each of a plurality of timeframes, (i) generating a cuboid for each set of associated bounding boxes, and (ii) for each cuboid, associating the cuboid with one of a plurality of tracklets based on (a) a position of the cuboid during the timeframe and (b) predicted future positions for each of the plurality of tracklets for the timeframe.

Abstract: An active inrush current limiter and method of limiting inrush current actively monitor line voltage and voltage drop across a current limiting resistance in a manner that eliminates the impact of fluctuations of line voltage on the decision of when to close a relay and bypass a current limiting resistance between the AC source and a group of power supplies. The active inrush current limiter includes a microcontroller connected to control the electronic switch and relay. The microcontroller is configured to sample the source AC power and detect a pattern of current flow through the electronic switch and current limiting resistance. A program executed in the microcontroller includes calculations that determine when to close the relay and bypass the current limiting resistance by detecting changes in power flow through the current limiting resistance that reliably correspond to a time when the capacitors in the power supplies have completed charging.
