MICROCLIMATE MANAGEMENT SYSTEM
First Claim
Patent Images
1. A microclimate management system comprising:
- a support device including a person contacting surface;
a fluid supply coupled with the support device and supplying fluid to the support device; and
a controller operatively coupled to the fluid supply and including an instruction set, the instruction set causing the controller to regulate at least one of the rate the fluid is supplied by the fluid supply and temperature of the fluid supplied by the fluid supply to maintain a heat withdrawal capacity of at least a portion of the person contacting surface below about 140 W/m2.

Abstract
A microclimate management system (10) comprises a mattress (16), a topper (18), and a control system (14). The topper (18) is coupled to the mattress (16) and is supported thereon. The topper (18) defines an interior region (42) and a person contacting surface (52). The control system (14) is configured to maintain at least one of a surface temperature, a relative surface humidity, and a heat withdrawal capacity of at least a portion of the person contacting surface (52) within a predetermined operating

198. A method of manufacturing a microclimate management system, comprising:
-
providing a support device in communication with a fluid supply, the support device including; a cover defining an interior region and at least a portion of the cover defining a person contacting surface, the cover also defining a fluid permeability parameter, a thermal conductivity parameter, and a thickness parameter, and a spacer positioned within the interior region, the spacer defining a fluid resistance parameter, a fluid permeability parameter, a thermal conductivity parameter, and a thickness parameter; and varying at least one of the fluid permeability parameter of the cover, the thickness parameter of the cover, the thermal conductivity of the cover, the fluid resistance parameter of the spacer, the fluid permeability parameter of the spacer, the thermal conductivity parameter of the spacer, and the thickness parameter of the spacer to cooperate with the fluid supply to maintain a heat withdrawal capacity of at least a portion of the person contacting surface below about 140 W/m2.
