An intra-cardiac mapping system is based on locating the ports through which blood flows in or out the heart chambers. For many procedures, such as ablation to cure atrial fibrillation, locating the pulmonary veins and the mitral valve accurately allows to perform a Maze procedure. The location of the ports and valves is based on using the convective cooling effect of the blood flow. The mapping can be performed by a catheter-deployed expandable net or a scanning catheter. The same net or catheter can also perform the ablation procedure.

A sprinkler system comprises a network of CPVC conduits and a plurality of sprinklers. The system includes an electrically activated solenoid control valve to allow fluid to flow in the pipe network. One or more fire detectors operate independently of the condition of the sprinklers. Upon detection of an incipient fire situation, a fire detector sends an electrical signal to cause activation of the control valve. Upon activation of the control valve, fire suppression fluid is caused to flow through the conduits before the incipient fire situation matures into a sprinkler-triggering event. The cooling effect of fluid flowing through the conduit enables the conduit to resist structural failure prior to sprinkler deployment. The control valve may be disposed at a remote location in the sprinkler line and be operable as part of an inspector's test connection.

A climate controlled seat, bed or other assembly configured to receive a person includes a blower and two or more thermoelectric devices or other conditioning fluid modules.

In one arrangement, the thermoelectric devices are sequenced between an activated and a deactivated position. Consequently, the desired cooling and/or cooling effect can be maintained while reducing energy consumption of the climate control system.

If a forced convection is generated by a cooling fan, there is generated a problem that a natural convection is prevented and a cooling effect in a region of the natural convection is lowered. The invention provides a structure in which an air flow generated by a forced convection does not come into contact with an air flow generated by a natural convection, by setting a partition all between a forced convection path in which the air flows on the basis of a forced convection generated by a cooling fan, and a natural convection path in which the air flows on the basis of a natural convection. Further, the partition wall is not provided near an upper end so as to draw in the air flowing through the natural convection path to a side of the forced convection path, thereby promoting the natural convection of the natural convection path.
