Abstract: A heater duct can be coupled to an instrument panel of a vehicle, and comprises a base, a nozzle, and a neck. The base is sealingly coupled to the instrument panel and includes an inlet opening to receive air from a heater. The nozzle includes an outlet opening and is fluidly connected to the base. The nozzle deflects the air through the outlet opening and toward a predetermined region of a windshield. The neck extends between and is sealingly coupled to the base and nozzle. The base, nozzle, and neck cooperate to at least partially define an interior volume. The heater duct is positioned in an orthogonal coordinate system comprising an x-axis, a y-axis, and a z-axis. Air flowing from the inlet opening through the interior volume toward the outlet opening follows a path sequentially extending in substantially a negative z-direction, substantially a negative y-direction, and substantially a positive z-direction.

Abstract: An air distribution system for the distribution of air to a rear portion of a vehicle includes a housing extending between a first and second end. The housing defines a plurality of first direct air outlets disposed adjacent the first end, a plurality of second direct air outlets disposed adjacent the second end, and a plurality of indirect air outlets disposed between the first and second direct air outlets. An airflow control assembly is configured to interchange airflow of the air distribution system between a first mode in which airflow is open through the direct air outlets but blocked from the indirect air outlets for guiding air directly to occupants situated in the rear portion of the vehicle and a second mode in which airflow is restricted through the direct air outlets and open through the indirect air outlets to create a bloom of air over the rear vehicle occupants.

Abstract: Active power factor correction (PFC) circuits are used to minimize unwanted harmonic distortion in applications where AC electrical power is rectified to produce DC power needed for operating electrical equipment. A variable amplitude regulator (VAR) is a PFC control interface which is simpler to implement than conventional circuits, and offers a wider dynamic operating range. The VAR functions as a resistor scaling network using a two-stage RC filter to maintain the DC output voltage constant for various load conditions and to maintain the rectified current in phase with the sinusoidal circuit flow in an AC power line, through both slow and rapid changes in the load coupled to the direct current output. This control interface offers excellent performance characteristics and requires only a few components for a useful implementation.

Abstract: An anti-backflow eductor has a resilient sealing sleeve disposed on a water port defining blind end tube. The sleeve has a thinner wall cross section at a discharge end to enhance sealing while facilitating increased water flow. The ports in the blind end tube extend into a radial tube flange at the tube's inlet end to facilitate water flow out of the ports between the sleeve and tube. A tapered seat in the housing, together with cross bars in the vents, reduces the air vent cross section and relative motion between sleeve and housing to reduce sleeve wear. The eductor comprises an anti-backflow housing and a venturi housing coupled together for relative rotation but being inseparable under normal conditions to inhibit venturi use without the anti-backflow function of the anti-backflow housing.
