Abstract: Alternators employing magnetic commutation, methods of manufacturing the alternators and wireless communications infrastructures employing the alternators. In one embodiment, an alternator includes: (1) a stator having 4n alternating field and armature poles extending axially along and projecting from an inner surface thereof, n being a positive integer, the field poles having field windings disposed thereabout to form alternating North-South magnetic polar regions and the armature poles having armature windings disposed thereabout to allow conduction of electric power from the armature poles, (2) a rotor, disposed within and journalled for rotation relative to the stator, having 2n axial magnetic passive regions, each of the passive regions being of a circumferential width magnetically to bridge one of the armature poles and only one of the field poles and (3) an exciter, coupled to the stator, that provides a controlled level of DC excitation to the field poles to regulate an output of the alternator.

Abstract: A protein designated p35 binds to a number of the chemotaxis-stimulating cytokines known as chemokines. p35 may be used to treat conditions that are mediated by chemokines, such as inflammation. p35 is a secreted protein that can be purified from the culture supernatant of cells infected with certain viruses, or produced using recombinant DNA techniques. Isolated DNA sequences encoding p35 are provided, along with expression vectors comprising the p35 DNA, and purified p35 protein.

Abstract: This invention includes selecting a desired pressure for fuel injection in an internal combustion engine. The selection improves control of fuel injection by keeping the fuel in the fuel rail in a liquid state and by keeping the fuel injectors in an operating region where fuel injector fuel flow is less sensitive to changes in fuel injector pulse width.

Abstract: An improved fusing apparatus for fixing or fusing images on print media is disclosed wherein a relatively small pressure applying surface, such as the surface of a rotatable pressure wheel, is lubricated with a lubricating medium such as silicone oil, and engages the printed image to apply pressure and fuse the image to the image receiving substrate. The fusing apparatus is mounted for reciprocal back and forth movement across the printed image on the image receiving substrate or medium to fuse the image into the substrate and flatten or smooth the upper exposed surface of the ink image. The pressure wheel is passed in multiple overlapping passes over the printed image to uniformly fuse the image into the media.

Abstract: An interactive user support system for a document processing system or an image producing device controls the operation of the machine using an internally stored knowledge base derived from information and rules provided by expels in the field. A plurality of sensors monitor the operation of the machine and a variety of user actions. If the system determines that the user needs help, by comparing the operation of the machine with the information and rules in the knowledge base, the system will interrupt the user and offer or provide assistance. If the user is performing proper steps to correct a problem or perform a specific job, the system will not interrupt the user. Additionally, the user may query the system for assistance or direction. The result is a more efficient document processing system or image producing device for use in any environment and able to be operated by a variety of users having a range of needs and abilities.
