Abstract: A pump assisted heat pipe may combine the low mass flow rate required of latent heat pipe transfer loops with a hermetically sealed pump to overcome the typical heat pipe capillary limit. This may result in a device with substantially higher heat transfer capacity over conventional pumped single-phase loops, heat pipes, loop heat pipes, and capillary pumped loops with very modest power requirements to operate. Further, one or more embodiments overcome the gravitation limitations in the conventional heat pipe configuration, e.g., when the heat addition zone is above the heat rejection zone, the capillary forces are required to transfer the liquid from the heat rejection zone to the heat addition zone against gravity.

Abstract: A system and method for list ordering based on frequency data or location is disclosed. The disclosed system and method can allow a user of a mobile device to quickly and efficiently add new items to a list by providing an ordered list of possible items from which the user selects. The list of possible items is ordered using frequency data to provide the most relevant items first based on item-to-item correlation, category correlation, and overall frequency. The list can also be reordered according to micro-location, such as that determined by using micro-location based sensor technology devices, to order the items by the shortest distance away from the mobile device.
