Abstract: A fabric assembly includes a knitted fabric and a filament. The knitted fabric is adapted to move between a stretched state extended along a direction of an applied force, and a relaxed state. The filament is disposed in the knitted fabric, and includes a plurality of loops longitudinally spaced apart from one-another. Each loop of the plurality of loops are adapted to project outward from the knitted fabric when in the stretched state, and substantially retract into the knitted fabric when in the relaxed state.

Abstract: Presented herein are active textile structures with selectively variable surface friction characteristics, methods for making/using such structures, and vehicle components fabricated with electronically controlled textile structures with modifiable surface friction characteristics. An active textile system for governing frictional force levels at an interface with a user or object is presented. The system includes a textile structure that is fabricated from interlaced first and second textile filaments. Each textile filament has a respective texture that exhibits a distinct coefficient of friction. The textile structure has an outer and/or upper contact surface at the interface with the user/object. An actuating element, which is connected to the textile structure, is operable to selectively transition the textile structure between first and second states. The first state includes the first textile filament defining the textile structure's outer contact surface, whereas the second state includes the second textile filament defining the outer contact surface.

Abstract: A knitted structure is configured for heat generation and distribution. In some embodiments, the knitted structure includes a knitted fabric including a first knitted layer and a second knitted layer opposite the first knitted layer. The first knitted layer has a first thermal conductivity. The second knitted layer has a second thermal conductivity. The second thermal conductivity is greater than the first thermal conductivity to faciliate heat transfer toward the first knitted layer. The knitted structure may further include a plurality of electrodes at least partially disposed inside the knitted fabric. Each of the plurality of electrodes is configured to generate heat within the knitted fabric upon receipt of electrical energy in order to distribute heat along the knitted structure and toward the first knitted layer.

Abstract: A panel assembly includes a frame and a textile panel. The frame has a first member and a second member spaced apart from each other. The textile panel is attached to and extends between the first member and the second member. A tension controlling system is attached to the textile panel. The tension controlling system is reconfigurable between a first state for tensioning the textile panel to provide a first tensile force and a first maximum sag distance, and a second state for tensioning the textile panel to provide a second tensile force and a second maximum sag distance. The first tensile force is greater than the second tensile force, and the first maximum sag distance is less than the second maximum sag distance.

Abstract: A device for supplying electric power includes a rectifier, an adaptive voltage clamping circuit, and a DC-DC voltage regulator. The rectifier receives electrical power, and is electrically connected to an input line of the adaptive voltage clamping circuit. The adaptive voltage clamping circuit includes a power transistor, a voltage feedback circuit, and a controller. The DC-DC voltage regulator is electrically connected to the adaptive voltage clamping circuit and, in one embodiment an actuator. The controller monitors the voltage feedback circuit and controls the power transistor to a fully open state to transfer electric power to the DC-DC voltage regulator when the voltage level supplied to the DC-DC voltage regulator is less than a threshold. The controller controls the power transistor in a linear state to regulate the voltage transferred to the DC-DC voltage regulator when the voltage level supplied to the DC-DC voltage regulator is greater than the threshold.
