Abstract: A prosthetic hand assembly includes a hand structure including an actuatable wrist, a palm, and a plurality of actuatable fingers coupled with a plurality of actuators each configured to selectively direct movement of the actuatable wrist, a camera disposed on one side of the hand structure, the camera is selectively operable to generate a plurality of successive images of an object positioned adjacent the hand structure, a processor coupled with the plurality of actuators, the processor is communicatively coupled with the camera and configured to receive the plurality of successive images of the object, wherein the processor is configured to determine one or more characteristic of the object from the plurality of successive images of the object, the processor is configured to selectively drive the plurality of actuators to affect the actuatable wrist and plurality of actuatable fingers based on the one or more characteristics.

Abstract: A vapor chamber device having a first vapor core configured to passively spread heat from a localized first input area to a relatively larger first output area adjacent to and in thermal contact with a heat output side of the vapor chamber device, and a second vapor core configured to passively spread heat from a localized second input area adjacent to and in thermal contact with a heat input side of the vapor chamber device to a relatively larger second output area in thermal contact with the first input area of the first vapor core. The second vapor core is configured to attenuate high heat flux hotspots on the first input area before the heat fluxes thereof pass through the second output area of the second vapor core to the first input area of the first vapor core.
