Abstract: A method and system for pose estimation includes receiving at least one image frame captured by an imaging device, wherein the imaging device is arranged to image at least one subject; determining one or more candidate positions for each of a plurality of human keypoints, wherein each candidate position is associated with a likelihood that a human keypoint is located at such position; generating one or more combinations of human keypoints based on the determined one or more candidate positions; and determining a pose of each of the at least one subject based at least on the one or more generated combinations of human keypoints.

Abstract: This application relates to a battery operated grease gun comprising a body able to be connected to a container configured to store grease, the body defining first and second elongate chambers therein, the first chamber extending along a first axis and the second chamber extending along a second axis, the first axis being spaced from the second axis, and the second chamber having a smaller cross-sectional area than the first chamber; first and second pistons, the first piston configured to reciprocate within the first chamber along the first axis and the second piston configured to reciprocate within the second chamber along the second axis, the second piston having a smaller cross-sectional area than the first piston; a common grease channel, the common grease channel being disposed between the container and the first and second chambers such that the grease is able to flow from the container into the first and second chambers; an actuator connected to the body and moveable between a retracted position, wher
