Abstract: A temperature conditioned insulated container in a vehicle selectively heats or cools items stored therein. A thermoelectric energy module is coupled to a heat exchanger plate disposed in a compartment of the container. A power control circuit controls power to the thermoelectric energy module and a cooling fan motor. The drive circuit drives the thermoelectric energy module with a decaying drive signal for a predetermined time after the vehicle is shut down to prevent damage to the thermoelectric energy module. In a defrost operation, the drive circuit provides a decaying drive signal to the thermoelectric module during the beginning of a defrost cycle. After providing no cooling for a predetermined time, the drive signal is increased until the refrigerator operating system returns to full operation. By slowly varying the drive power in these situations, thermal stresses within the thermoelectric energy module are reduced.

Abstract: A high pressure cryogenic fluid dispensing system features a tank containing a cryogenic liquid with a liquid side and a head space there above. A pressure building coil featuring a section of parallel heat exchangers and a section of series heat exchangers receives liquid from the tank through a pressure building regulator valve and a pair of surge check valves. The liquid flashes to gas in the section of parallel heat exchangers and the resulting gas is forced to the section of series heat exchangers where it is pressurized and warmed. The gas may be directed to a warming coil for dispensing and to the head space of the tank to rapidly pressurize it. Gas traveling to the head space flows through an vapor space withdrawal control valve. The vapor space withdrawal control valve and pressure building regulator valve may be automated via a controller that provides pressure building when the tank pressure drops below the system operating pressure.

Abstract: One of the most significant safety concerns in the automation of extracorporeal blood treatments such as dialysis is the risk of blood leakage. Extracorporeal blood treatment systems draw blood at such a high rate that a loss of integrity in the blood circuit can be catastrophic.
