20110048048 | Personal Cooling System - A personal cooling system operates by pumping liquid through a garment. Because the personal cooling system pumps liquid, the compression system that generates the cooling power does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the cooling system operates in the critical flow regime in which the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to an increased pressure. | 03-03-2011 |

Because the portable cooling unit pumps liquid, the compression system that generates the cooling power does not require the use of a condenser. The compression system utilizes a compression wave. An evaporator of the cooling unit operates in the critical flow regime in which the pressure in an evaporator tube will remain almost constant and then ‘jump’ or ‘shock up’ to an increased pressure. | 03-03-2011 |
20110048066 | Battery Cooling - A battery cooling system operates by pumping liquid through a cooling fluid circulation path. Because the battery cooling system pumps liquid, the compression system that generates the cooling power does not require the use of a condenser. The compression system utilizes a compression wave.

20110051549 | Nucleation Ring for a Central Insert - A central insert causes maximum fluid velocity to shift away from an external tube wall reducing friction losses at the tube wall. Centrifugal forces pull fluid away from a central insert wall minimizing friction at the insert wall. The insert may be used in the context of nozzles, flow tubes, vortex tubes, and other fluid pathways. In a nozzle, grooves may be added to the nozzle wall. By introducing these grooves at the exit or end of a nozzle, nucleation may be improved and cavitation may be triggered prior to a fluid entering an expansion tube. The nucleation ring may also be placed at the beginning of a nozzle such that cavitation starts within the nozzle. | 03-03-2011 |
