Various articles of apparel having a cylindrical portion, such as an arm region or a leg region, for extending around a joint (such as an elbow or a knee) of a wearer are disclosed. The cylindrical portion includes a textile material, for example, and a pattern located on a surface of the textile material or knitted into the textile material. The pattern has a first density in at least one area of the cylindrical portion oriented substantially parallel to a plane of bending of the joint, and the pattern has a second density in at least one area of the cylindrical portion oriented substantially perpendicular to the plane of bending of the joint. A purpose of the pattern may be to decrease the probability of an overuse syndrome or other injury occurring as a result of use of the joint.

A pad element may include a base member, a pair of cover layers, and a plurality of beads. The base member defines a plurality of apertures. The cover layers are secured to opposite surfaces of the base member and extend across the apertures. The beads are located within the apertures and between the cover layers. As examples, the base member and the beads may be formed from polymer foam materials, and the cover layers may be formed from textile materials. The pad element may be utilized to attenuate impact forces and provide one or more of breathability, flexibility, a relatively low overall mass, and launderability.

A shore power HVAC system for a vehicle is provided. The vehicle has a vehicular HVAC system with an engine compressor, a condenser, and an expansion valve and an evaporator coupled to each other in series by a plurality of conduits. The shore power HVAC system includes an electric compressor structured to compress a coolant fluid and a diverter valve structured to allow fluid to pass through a selected fluid path. The electric compressor is coupled to, and in fluid communication with the evaporator and the diverter valve. The diverter valve is further coupled to the engine compressor. Thus, a first coolant fluid loop and a second coolant fluid loop are created. The first coolant fluid loop passes through, in series, the engine compressor, the diverter valve, the condenser, the expansion valve, and the evaporator. The second coolant fluid loop passes through, in series, the electric compressor, the diverter valve, the condenser, the expansion valve and the evaporator. The diverter valve selectively directs which loop the coolant fluid may pass through.

A supercharging system for an engine includes an air pump, an electrical machine, an engine-connected input member and a variable-ratio power transmission mechanism. The power transmission mechanism includes a sun member operatively connected to one of the air pump, the electrical machine and the input member. At least one planet member is drivingly interfaced with the sun member and rotatably carried by a carrier operatively connected to another one of the air pump, the electrical machine and the input member. An annulus is drivingly interfaced with the at least one planet member and operatively connected to the other one of the air pump, the electrical machine and the input member. The supercharging system also includes a brake configured to selectively inhibit rotation of at least one of the sun member, the carrier, and the annulus.

A structure for vertically housing an electronic component is disclosed as including a bottom support member and a top support member. The top support member is substantially parallel to the bottom support member. An open space is formed between the top support member and the bottom support member whereby the electronic component may be placed into the open space in a vertical orientation. A ventilating structure is disposed outside of the open space and is capable of channeling air into a middle portion of the electronic component in the open space.

Articles of manufacture and a method of making the articles are provided. The articles of manufacture comprise CpFlu metallocene catalyzed polypropylene homopolymers and C2–C3 random copolymers having narrow molecular weight distributions and low xylene solubles (or extractables) contents. Because of a number of desirable properties, the polypropylene homopolymers and C2–C3 random copolymers may be used to prepare a wide variety of useful articles, including but not limited to cast films, such as packaging; fibers suitable for use in fabrics and carpet applications, and injection and blow molded items such as bottles.

A double-lever mechanism is for the trip actuator of a circuit breaker having a housing, separable contacts and an operating member for opening and closing the contacts. A trip bar opens the separable contacts in response to a trip condition, such as an overcurrent condition. The trip actuator assembly is a self-contained unit including an actuation subassembly comprising the double-lever mechanism and a coil and a plunger housed within an enclosure. First and second trip levers of the double-lever mechanism are pivotally coupled to first and second ends of the enclosure, respectively. In response to the trip condition, the plunger extends, pivoting the first trip lever which engages and pivots the second trip lever in order to actuate the trip bar. The double-lever mechanism provides a mechanical advantage by reducing actuating forces and plunger travel.
