Abstract: In an exemplary embodiment, an interior heating system for occupant seats of a vehicle is provided. The interior heating system uses a weft co-knit fabric combined with at least one conductive electrode to heat selective regions of a vehicle seat. The interior heating system includes the weft co-knit fabric that contains a set of weft knit active or plated emitting yarn configured with at least one conductive electrode. The knit active or plated emitting yarn is co-knit with at least one parent yarn for enhanced uniformity of an electrical current applied to at least one conductive electrode from the weft co-knit fabric, and a plurality of conductive electrodes arranged in an interdigitated layout to combine together each conductive electrode with a set of a plurality of conductive co-knit active emitting yarns which attach to each electrode tine of the conductive electrode in a select region.

Abstract: A valve assembly includes a body having a longitudinal axis and defining a cavity therein. A shuttle valve is arranged within the cavity. The shuttle valve has a first surface and a second, opposing surface. An actuator element is adjacent the first surface of the shuttle valve and configured for translating the shuttle valve along the longitudinal axis between a first position and a second position. The actuator element is formed from a shape memory alloy that is transitionable between a martensite crystallographic phase and an austenite crystallographic phase in response to a thermal activation signal to thereby translate the shuttle valve between the first position and the second position. Furthermore, a resilient member is adjacent the second surface of the shuttle valve. The resilient member is configured to oppose the movement of the shuttle valve moving from the first position to the second position.
