Abstract: A standoff connection structure which is suitable for connecting a standoff connector and a high-voltage electronic box. The standoff connection structure includes at least one anti-rotation feature, and also includes various sealing features to provide a leak-tight connection between a standoff connector and high voltage electronic box, even after exposure to thermal shock. The standoff connector also facilitates an electrical connection between a high voltage or high current component and the high voltage electronic box.

Abstract: This disclosure describes techniques for increasing wetting current for an electromechanical switch. In one example application, an aircraft may include one or more valves used to control the temperature of aircraft interior. The valves may include one or more valve position switches to indicate certain valve positions, e.g. fully open, fully closed, fifty percent open, and so on. In some examples, the valve position switches may receive current at electromechanical contacts of the switch that is less than the wetting current. The techniques of this disclosure provide additional wetting current at the time the switch contacts close to improve reliability of the valve position switches. In some examples, an analog to digital converter circuit may be configured to provide the additional wetting current to the switch.

Abstract: An electronic control unit having a sealed housing including a main body and a cover fixed to one another and a sealing element in contact with one and/or the other of the main body and the cover. The control unit also includes a circuit board arrangement in the housing which a circuit board is located. In addition, the control unit also includes at least one housing stabilizing element in contact with the circuit board arrangement and one or the other of the main body and the cover.

Abstract: A housing for an electronic control unit is disclosed. The housing contains a main body having a base and a wall rising from the base, a cover supported on the wall opposite to the base and fixed to the housing for defining an inner volume, and a seat on the wall for a sealant interposed between the main body and the cover contributing to isolate the inner volume from an outer volume. The seat contains a portion adjoining the inner volume or the outer volume, the portion having an edge on the wall inclined with respect to the cover.

Abstract: A gas distribution system may include a gas mass flow sensor with a resistive element configured to be heated, a thermally conductive shell surrounding the resistive element and heat-transfer control elements. The shell may include a leading surface oriented substantially orthogonal to a direction of gas flow. The heat-transfer control elements may be positioned to focus heat transfer from the resistive element through the leading surface of the shell so that a rate of heat transfer is independent from the variations in flow configuration.

Abstract: A seal assembly for deflecting contaminated fluid flowing through the seal assembly from an upstream space to a downstream space includes an annular housing, at least one vent hole peripherally disposed on the annular housing, a first set of seals disposed within the annular housing adjacent to the downstream space, the first set of seals having an inclined surface to deflect the flow of contaminated fluid through the at least one vent hole, and a second set of seals mounted on the shaft, disposed within the annular housing, adjacent to the first set of seals and adjacent to the upstream space. The second set of seals may have larger inside diameter than the first set of seals. The seal assembly may prevent contaminated fluid from entering an air bearing cooling circuit, thereby preventing bearing wear, erosion and failure.

Abstract: A lightweight mountain bike frame made out of welded aluminum tubing heavily reinforced with open ended gussets, whose design allows peak stress to be more evenly distributed. The design moves the shock mount forward so that the rocker arm fits around the seat tube without mounting a pivot to it, resulting in the weight of the suspension to move to the center of gravity for both bike and rider.

Abstract: An innovated rear suspension system for mountain bikes that includes five structural tubes—a force channeling tube, a front stabilizing tube, a rear stabilizing tube, a top tube, and a seat tube—connected to form an irregular polygon; reinforced with gussets, a torque conversion device pivotally connected to a compression strut, a shock-absorbing element and the force channeling tube, which transfers force or shock from the compression strut to the shock-absorbing element. The shock-absorbing element pivotally connected at the front to a pair of shock mounts attached to the force channeling tube absorbs and compresses force from the torque conversion device and transfers the force to the force channeling tube. The upward and forward direction of the force channeling tube guides the force along the force channeling tube propelling the bicycle and the rider forward, reducing jacking and efficiently utilizing pedal forces.

Abstract: The invention provides an easily gripped, single use or multiple use, packet applicator that contains, protects, dispenses and applies powders, solids, semi-solids, semi-liquids, and liquids. The packet contents, or “payload”, are selected from a wide variety of personal care, domestic, office, commercial, and industrial substances, such as: sunscreen, soap, cosmetics, cosmetics removers, and medicaments for application to epidermis and other body surfaces; detergents, waxes, cleansers, and polishes for application to household surfaces; and lubricants, paints, sensors, and sealants for application to commercial and industrial surfaces. Embodiments of the packet applicator can include a rotatable grip.

Abstract: A foil journal bearing with a dual stiffness spring comprises a housing, a shaft arranged for relative coaxial rotation with respect to the housing, and a single spring layer surrounding the shaft. The single spring layer may have a first linear spring rate and a second linear spring rate wherein the first linear spring rate is formed by first pitch corrugations along a length of the single spring layer and the second linear spring rate is formed by second pitch corrugations along a length of the single spring layer. In an aspect of the invention, the foil journal bearing provides a top foil having first and second ends positioned in a notch in the housing. In an aspect of the invention, the single spring layer maintains a ratio of three of the second pitch corrugations to each of the first pitch corrugations.
