Control schemes and features for climate-controlled beds

Abstract: A climate-conditioned bed includes an upper portion having at least a first climate zone and at least one fluid module associated with such a first climate zone. The fluid module comprises a fluid transfer device for selectively moving a fluid and a thermoelectric device for selectively heating or cooling a fluid. The bed additionally includes one or more control modules configured to regulate the operation of the fluid module, at least one input device configured to allow an occupant to select a setting or mode associated with the first climate zone and at least a first temperature sensor configured to detect a temperature associated with the first climate zone of the thermally-conditioned bed. In some embodiments, the fluid module is operatively connected to the control module. The control module is configured to adjust at least one operational parameter of the fluid module based on, at least in part, the setting or mode selected by an occupant using the at least one input device, and the temperature detected by the first temperature sensor.

Fluid delivery systems for climate controlled seats

Abstract: A seat portion or a backrest portion of seating assembly comprises a recessed area or wide groove along its exterior surface. The recessed area can be configured to receive a spacer (e.g., spacer fabric, member, module, etc.) that helps maintains the spatial and structural integrity of the recessed area. The spacer can be generally air and fluid permeable. In addition, a scrim layer can be positioned over the spacer fabric to help direct and/or distribute air or other fluid to an exterior surface of the seating assembly. The recessed area can also be configured to receive one or more films, occupant sensory devices, comfort layers, scrims, temperature sensors, heating devices and/or the like. Thus, air or other fluid can be delivered into the recessed area of a seat or backrest portion of a seating assembly, and subsequently delivered through the spacer fabric and scrim layer towards or away from an occupant. In some embodiments, the air or fluid is conditioned (e.g., heated or cooled) prior to entering the recessed area.

Apparatus for providing fluid through a vehicle seat

Abstract: A seat assembly comprises a seat cushion having an outer surface comprising a front side for supporting an occupant in a sitting position and a rear side. A base member is positioned on the rear side of the seat cushion. An adjustable lumbar support device is provided on the rear side of the seat cushion. A first passage extends through the seat cushion. A ventilation system is provided for distributing air from the first passage along the support surface of the seat cushion. A climate control apparatus is provided for providing climate conditioned air to the ventilation system. A flexible conduit connects the climate control apparatus to the ventilation system.

Systems and methods for cooling inductive charging assemblies

Abstract: In some embodiments, a cooling system for an inductive charger includes a thermal conditioning assembly in fluid communication with an inductive charging assembly. The inductive charging assembly can include a dock and an inductive charging module. The dock can be configured to receive a portable electronic device, such as a cell phone, that is configured to accept inductive charging from the inductive charging module. The thermal conditioning assembly can include a fluid transfer device and a thermal conditioning module, such as a thermoelectric device. In various embodiments, heat (e.g., heat produced during inductive charging) can be transferred from the inductive charging assembly to the thermal conditioning module and/or to a fluid flow produced by the fluid transfer device, thereby cooling the inductive charging assembly and/or the portable electronic device.

Structure based fluid distribution system

Abstract: A climate controlled seat assembly includes a seat cushion that has an outer surface with a first side for supporting an occupant in a seated position and a second side, which generally faces in an opposite direction than the first side. An air passage extends from the first side to the second side of the seat cushion. A support member has a first side that is configured to provide support to the seat cushion and a second side. the first side and the second side of the support member generally face in opposite directions. A distribution passage is in communication with the air passage and is formed at least in part by a recess formed at least in part in one of the first side of the support member and the second side of the seat cushion.

Nanotechnology in Textiles

Abstract: Increasing customer demand for durable and functional apparel manufactured in a sustainable manner has created an opportunity for nanomaterials to be integrated into textile substrates. Nanomoieties can induce stain repellence, wrinkle-freeness, static elimination, and electrical conductivity to fibers without compromising their comfort and flexibility. Nanomaterials also offer a wider application potential to create connected garments that can sense and respond to external stimuli via electrical, color, or physiological signals. This review discusses electronic and photonic nanotechnologies that are integrated with textiles and shows their applications in displays, sensing, and drug release within the context of performance, durability, and connectivity. Risk factors including nanotoxicity, nanomaterial release during washing, and environmental impact of nanotextiles based on life cycle assessments have been evaluated. This review also provides an analysis of nanotechnology consolidation in the textiles ...

Climate controlled bed assembly

Abstract: According to certain arrangements, a climate controlled bed includes an upper portion comprising a core with a top core surface and a bottom core surface. The core includes at least one passageway extending from the top core surface to the bottom core surface. The upper portion of the bed further includes at least one fluid distribution member positioned above the core, wherein the fluid distribution member is in fluid communication with at least one passageway of the core. The fluid distribution member is configured to at least partially distribute fluid within said fluid distribution member. The upper portion of the bed further comprises at least one comfort layer positioned adjacent to the fluid distribution member. The bed also includes a lower portion configured to support the upper portion and at least one fluid module configured to selectively transfer air to or from the fluid distribution member of the upper portion. In some arrangements, the fluid module includes a fluid transfer device and a thermoelectric device for selectively thermally conditioning fluids being transferred by the fluid transfer device.
