Abstract: The present invention provides a method for close control and adjustment of in-cylinder oxygen concentration levels together with boost adjustments in such a way as to minimize harmful emissions during transients in engines which utilize late direct cylinder injection of fuel. In this invention, EGR flow rates are adjusted by means of an EGR control valve in a closed loop, linked fashion together with boost pressure changes during transients, to maintain intake charge-air oxygen concentration and boost levels within critical ranges for controlled temperature, low emission combustion. Furthermore, in order to minimize harmful emissions during rapid transient changes in operating conditions, changes in fuel feed into the cylinder are made to wait for or follow changes in the boost level of charge-air into the cylinder for combustion.

Abstract: A side rail is formed into a ring shape having its generally rectangular section that has an outer surface 3 formed with a pair of edge surfaces 5 of small radius, and an intermediate surface 6 of large radius of curvature formed between the edge surfaces 5. When the side rail is in the inclined condition in operation, each edge surface 5 can easily ride on oil film on cylinder 16 and allow the side rail 1 to perform smooth sliding movement on the inner surface of cylinder. The intermediate surface 6 efficiently scrapes lubricating oil on cylinder to form lubricating oil film of necessary and minimum thickness between an inner surface 17 of cylinder 16 and side rail 1. Also, the larger radius of curvature for forming the intermediate surface 6 provides a larger contact area to the inner surface 17 of cylinder 16 to improve wear resistance.

Abstract: The present invention is a “three bar” rear wheel suspension system with increased lateral stiffness and reduced tendency for pedal induced bobbing. The rear wheel suspension system of the present invention features a rigid one-piece rear frame section and a short link that are attached with the front frame section at three pivot points. Movement of rear frame section along an arc defined by the length of the short link rather than along the arc that defines by the distance between the bottom yoke pivot point and the top yoke pivot point causes the rear frame section to flex. Active flexing of the rear frame section as it moves through its suspension range absorbs additional energy from the movement of the rear wheel resulting in an “active arc” second suspension system.

Abstract: A intelligent label comprising a radio frequency transponder coupled to a global positioning system, a magnetic field sensing system, and/or a fingerprint sensor system, all of which are attached to a substrate. Once the intelligent label utilizing a global positioning system is attached to an object, it will enable the object to be tracked as it moves from one point to another point. As the object moves, the global positioning system receives signals from GPS satellites and processes those signals into location data. The data is then either transmitted directly to an interrogation station by the radio frequency transponder, or stored in a memory. The memory serves to allow all or part of the previous location data to be stored for transmittal to an interrogator at a later date.

Abstract: A document is printed with graphical symbols which encode information but are not human readable; the graphical symbols are formed into some or all of an element which is human readable. Prior art graphical symbols have not been assembly into any kind of human readable element, such as a picture, logo, word, signature or sea. Instead, they have generally been large and obtrusive blocks which considerably mar the appearance of a printed document. This negative impact on appearance has been one of the major causes inhibiting the uptake of graphical symbol technology (e.g. glyphs) for encoding information.

Abstract: A Reciprocating Generator Wave Power Buoy consists of a reciprocating generator rigidly attached to the underside of an ocean buoy and creates electric power from the surface ocean swells. The generator coil maintains a stable position beneath the ocean surface while the magnetic field housing reciprocates with the vertical motion of the buoy in response to interaction with swell and waves on the surface of the ocean. Damping plates attached to the generator coil inhibit the motion of the generator coil, thus keeping it in a stable position relative to the motion of the magnetic housing. The magnetic housing focuses the magnetic field through the generator coil and the relative motion between the magnetic housing and generator coil creates an electromotive force in the coil. The design of the generator provides a uniform field of single magnetic orientation throughout the entire stroke of the generator.
