InactiveUSRE38128E1Minimizing possible occupant discomfortLimited powerAir-treating devicesSeat heating/ventillating devicesAuto regulationControl system
A temperature climate control system comprises a variable temperature seat, at least one heat pump, at least one heat pump temperature sensor, and a controller. Each heat pump comprises a number of Peltier thermoelectric modules for temperature conditioning the air in a main heat exchanger and a main exchanger fan for passing the conditioned air from the main exchanger to the variable temperature seat. The Peltier modules and each main fan may be manually adjusted via a temperature switch and a fan switch, respectively. Additionally, the temperature climate control system may comprise a number of additional temperature sensors to monitor the temperature of the ambient air surrounding the occupant as well as the temperature of the conditioned air directed to the occupant. The controller is configured to automatically regulate the operation of the Peltier modules and / or each main fan according to a temperature climate control algorithm designed both to maximize occupant comfort during normal operation, and minimize possible equipment damage, occupant discomfort, or occupant injury in the event of a heat pump malfunction.

Gelatinous cushions with buckling columns
InactiveUS6026527AEliminates pressure peakMaximize surface areaSolesStuffed mattressesCushioningEngineering
A cushioning element that has a number of substantially parallel elongate columns which buckle under an appropriate load. The cushioning element may be formed from a soft, easily deformable elastic or visco-elastic cushioning media. As a force is exerted against the cushioning element generally parallel to a column, the cushioning media may compress, and eventually the walls of the column may buckle. This equalizes pressure across the contact area of the object being cushioned.

Method for producing gate stack sidewall spacers
A method for forming sidewall spacers on a gate stack by depositing one or more layers of silicon containing materials using PECVD process(es) on a gate structure to produce a spacer having an overall k value of about 3.0 to about 5.0. The silicon containing materials may be silicon carbide, oxygen doped silicon carbide, nitrogen doped silicon carbide, carbon doped silicon nitride, nitrogen doped silicon oxycarbide, or combinations thereof. The deposition is performed in a plasma enhanced chemical vapor deposition chamber and the deposition temperature is less than 450° C. The sidewall spacers so produced provide good capacity resistance, as well as excellent structural stability and hermeticity.
