Abstract: A pressure regulator includes an inlet channel, an outlet channel, a bladder, a first plate, and a second plate. The bladder is connected to the outlet channel and extends alongside of the inlet channel. The first plate is disposed on one side of the inlet channel between the bladder and the inlet channel. The second plate is disposed on the other side of the bladder and is at least partially aligned with the first plate along the length of the inlet channel such that a portion of the inlet channel is disposed between the first and second plates. When the bladder is pressurized, the bladder urges the first plate toward the second plate and thereby pinches the portion of the inlet channel disposed between the first and second plates to regulate a ratio of a pressure in the outlet channel to a pressure in the inlet channel.

Abstract: A method of forming a spacer fabric includes performing, via a knitting machine, an iterative process. The iterative process includes: knitting a tether from a first point to a second point on a first fabric layer; extending the tether from the second point to a third point on a second fabric layer to start formation of a tether segment; temporarily holding the tether at the third point via one of a temporary holding needles; extending the tether from the third point to a fourth point on the first fabric layer; temporarily holding the tether at the fourth point via another one of the temporary holding needles; extending the tether from the fourth point to a fifth point on the second fabric layer; and knitting the tether from the fifth point to a final point on the second fabric layer. The tether segment is released from the temporary holding needles.

Abstract: A multi-layer bladder includes: a first bladder layer; a mask including a plurality of apertures; a second bladder layer bonded to the first bladder layer within the apertures in the mask and where the mask is not present between the first and second bladder layers, where the mask is configured to prevent bonding of the second bladder layer to the first bladder layer where the mask is present; and a fluid channel that is located between the first and second bladder layers and that extends to the mask from an outer edge of the multi-layer bladder.

Abstract: The knitted textiles include a knitted structure including a plurality of hollow yarns. Each hollow yarn includes a yarn body and defines a yarn hole extending through the yarn body to allow expansion of the yarn body upon inflation of each hollow yarn through the yarn hole. The knitted structure is configured to transition from an unexpanded state to an expanded state in response to the inflation of the hollow yarns through the yarn hole. The knitted structure has a first porosity in the unexpanded state, and the knitted structure has a second porosity in the expanded state. The second porosity is less than the first porosity such that a visibility through the knitted structure is greater when the knitted structure is in the unexpanded state than when the knitted structure is in the expanded state.

Abstract: Systems and methods for optimizing operator-state detection including tracking position of an operator-facing camera are described. Systems and methods include receiving a first image captured by an operator-facing camera, detecting a first position of the operator-facing camera with respect to the calibration object, ascertaining the first position with respect to at least one fiducial marker within a passenger compartment of a vehicle, capturing, via controller, a second image using the operator-facing camera, determining the second image is captured by the operator-facing camera from a second position with respect to the at least one fiducial marker, and analyzing, based on determining the second image is captured by the operator-facing camera from the second position, the second image to identify facial features of the operator. The receiving, detecting, ascertaining, determining, and analyzing are performed via a controller. The first image includes a calibration object disposed at a predetermined location.

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 facilitate 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 shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

Abstract: An inflatable system includes a bladder configured to contain fluid, a first plurality of tethers disposed within a first region of the bladder, and a second plurality of tethers disposed within a second region of the bladder. The first plurality of tethers has a first tether length, a first tether spacing, a first tether angle relative to one wall of the bladder, and a first tether stiffness. The second plurality of tethers has a second tether length, a second tether spacing, a second tether angle relative to the one wall, and a second tether stiffness. At least one of: the second tether length is different than the first tether length; the second tether spacing is different than the first tether spacing; the second tether angle is different than the first tether angle; and the second tether stiffness is different than the first tether stiffness.
