Abstract: A straddle-type vehicle (100) includes a frame (20) and an engine (10) mounted on the frame (20), the engine (10) includes a cylinder head (11) positioned toward the rear end of the frame, and located below a saddle seat (80). The cylinder head laces toward the rear end of the frame, which allows the heated cylinder head of the engine and the exhaust pipe connected to the cylinder head to avoid contact with the vehicle the user's legs while riding the vehicle, so the effect of heat emitted from the cylinder head on the rider's experience is reduced.

Abstract: Compositions used in, and methods for, fabricating a rear-passivated silicon solar cell are described. A novel method of opening the back surface for contacting the silicon with a conventional aluminum paste is described. Various novel screen printable etch resists are described. First, such an etch resist can be printed on the rear of a rear-passivated solar cell wafer. The passivation layer can then be removed using a wet etch, and next the etch resist layer can be removed. Further, an additional wet etch step may optionally be used to deepen the opening into the silicon and enhance the BSF (back-surface field). Aluminum paste can then be printed over the entire backside of the now etched cell. The entire cell is then fired. In exemplary embodiments of the present invention, the paste can be chosen so that it will not fire through the passivation layer.

Abstract: Various embodiments include systems and methods for managing radio utilization by a processor of a wireless access point. In response to receiving an access request from a wireless station, the processor may determine whether a multi-user (MU) physical layer quality of a communication link between a radio of the access point and the wireless station exceeds a quality threshold. The processor may determine whether a load of the radio of the access point is below a load threshold in response to determining that the MU physical layer quality of the communication link exceeds the quality threshold. The processor may associate the wireless station with the radio of the access point in response to determining that the load of the radio of the access point is below the load threshold. The processor may monitor established communication links to determine whether a change in association of radios with wireless stations is appropriate.

Abstract: The composition of an electrode thick film paste used in forming electrical contacts with silicon solar cells is disclosed. The thick film paste is comprised of an electrically conductive metal, an organic vehicle system and a system of inorganic additives. The conductive metal is silver and employs a high surface area material in order to improve fine line printing. The organic system makes use of highly soluble binder materials to enable higher loading of the total resin in the paste that improves the printability and print qualities of fine lines. The improved solubility also broadens the range of thixotropes that can be used to further improve printed line properties. In the organic system, a high surface tension solvent is used to improve line quality metrics such as ‘aspect ratio’. The inorganic glass and additives include compounds of lead, tellurium and thallium that improve the electrode contact to, and light conversion efficiency of, the silicon solar cell.
