Abstract: In a backlight apparatus, a master driving circuit generates a transmission frame including a training period including a clock training pattern and a data period including a plurality of data packets respectively corresponding to the plurality of blocks. A plurality of slave driving circuits correspond to the plurality of blocks, respectively, and are connected to the master driving circuit in a daisy chain structure. Each slave driving circuit receives the transmission frame through the daisy chain structure, recovers a clock based on the clock training pattern, and drives the plurality of light emitting elements included in a corresponding block among the plurality of blocks based on its own data packet among a plurality of data packets.

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 example operation may include one or more of receiving blockchain transactions, sorting an order of the blockchain transactions, simulating committance processing of the plurality of blockchain transactions to identify mining costs associated with each of the plurality of blockchain transactions, and applying one or more heuristic procedures to select one or more of the plurality of blockchain transactions which maximize a result associated with a next blockchain block.

Abstract: An example operation may include one or more of determining, by a first blockchain node, a need for a rental asset unable to be provided by the first blockchain node, requesting use of the rental asset from a second blockchain node controlling the rental asset, reserving, by the second blockchain node, the rental asset, utilizing the rental asset, designating the rental asset as in-use, and in response to the rental asset no longer being in-use. returning control of the rental asset to the second blockchain node.

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 hydrodynamic bearing set, for use with a thrust disk disposed between planar surfaces of a housing, includes first and second topfoils disposed adjacent first and second thrust disk axial bearing surfaces and removably secured to the housing. An underspring is secured between each planar housing surface and the corresponding topfoil. Dual-leaf spring pairs attached to at least one topfoil periphery function to urge the topfoils away from the thrust disk axial bearing surfaces by applying a force against a planar housing surface, another topfoil, or a spacer washer secured between adjacent topfoil dual-leaf pairs or frictionally retained within the housing. Alternatively, a wavy washer, a conical spring, a Belleville washer, or a coil spring can be substituted for the dual-leaf spring pairs.

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.
