The present invention provides a method and apparatus for mounting a stent onto a balloon on a stent delivery system. A stent is then loaded onto the delivery system and the resulting stent/balloon assembly is positioned in a first section of a mould and a second section of the mould is closed onto the first section and locked in place. Pressure is applied to the delivery system through a luer and the mould is heated. The pressure and heat are discontinued and the mould is cooled; this combination of heat and pressure secures the stent to the balloon. The method may include a cooling cycle to help retain the profile of the final stent delivery assembly.

Modular data center containers with modular components suitable for use with rack or shelf mount computing systems currently use cooling methods that do not include economizers due to size constraints of structural steel support infrastructure associated with modular data centers and removable economizers to facilitate portability of modular data centers. The modules allows introduction of outside air to the cooling cycle with the unique elements embodied within airside economizer components. The modules in conjunction with the data center represents a new and useful process to allow the economizer elements to bring outside air into the modular data center cooling cycle.

A cooling system for a portable computer can include a frame having a heat-source connecting unit in its one side and having a fan housing unit in its other side. A dissipating unit on one side of the fan housing unit performs heat exchange and a dissipating fan forms an air stream that can pass through the dissipating unit.

A SMA actuator having rigid members and SMA wires, in which improved temperature control of the SMA wires of the actuator is provided by a heat sink, which may be the rigid members themselves, in close proximity to at least a central portion of the wires. Optionally, the heat sink is sized and placed such that the end portions of the wires where they are attached to the rigid members are not in close proximity to the heat sink. Where the heat sink is external, it optionally has a cooling element that acts passively as a heat sink during the heating cycle of the actuator and that acts as an active cooling element during the cooling cycle of the actuator. An SMA actuator having a desired contraction limit and a power supply circuit has a switch in the power supply circuit that is normally closed when the actuator is contracted to less than the desired contraction limit and is opened by the actuator reaching the desired contraction limit. This improved temperature control provides greater cooling of the SMA wires for a faster response and an extended working life of the actuator.

The invention relates to a thermal generator (1) characterised in that it comprises at least one thermal module (10) including N adjacent magneto-caloric members (2) arranged in a circle about a central axis (A) and submitted to a magnetic field variation generated by a magnetic means (3) in order to vary their temperature. The magneto-caloric members (2) are associated with N pistons (40) driven according to a reciprocating translation movement by a control cam (70) in order to move the heat-carrier fluid contained in the thermal module (10) simultaneously in two opposite directions, so that a first fraction of the heat-carrier fluid flows towards a hot exchange chamber (5) through the magneto-caloric members (2) submitted to a heating cycle, and so that a second fraction of the heat-carrier fluid flows towards a cold exchange chamber (6) through the magneto-caloric members (2) submitted to a cooling cycle, and vice versa. The exchange chambers (5, 6) are coupled to outer calorie- and frigorie-consuming circuits, such as heating circuits, air conditioning circuits, tempering circuits, etc.

A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.

Devices and methods for moisture removal from conditioned air. A speed control is provided that selectively operates the blower motor of an air conditioning system at a lower speed. The speed control may include a time delay circuit and single pole, double throw relay. The speed control is used to slow the speed of the air cycler during the initial stage of a cooling cycle.

The system is programmed to close the motorized outside air damper in the event that humidity levels exceed a predetermined level, thereby limiting further entry of humid outside air into the home.
