  • Publication number: 20060013626
    Abstract: A xerographic printer or copier includes a replaceable cartridge having a cleaning blade and carrier particle pickoff member associated with a rotating charge receptor. As the cartridge is being used, carrier particles removed from the photoreceptor by the cleaning blade are magnetically retained on the pickoff member, where the remain for the balance of the lifetime of the cartridge. When a useable lifetime of the cartridge is spent, the carrier particles are removed from the pickoff blade.

  • Publication number: 20050144306
    Abstract: A method for managing data traffic in a multiple-user multiple simultaneous access environment using a channel load estimate and a calculation. The estimate or estimates are used to calculate a congestion threshold (CT) and to select a current congestion threshold broadcast to all potential users. An experiment is performed by users comparing that congestion threshold value and a random number to determine if a packet is eligible to be transmitted, thus throttling the random transmission of packets so that the transmitted load from the terminal has a rate of packet transmission that is less than the congestion threshold times the offered load (from the user), where the congestion threshold value is related to the probability of a globally successful transmission of a number of simultaneously transmitted packets. A quality of service (QOS) factor may also throttle the transmitted load.

  • Publication number: 20050086453
    Abstract: A method and apparatus provides the capability for a single function to safely use multiple register windows within the same function, with minimal additional support from the operating system, by specifying a new window pointer, the “Effective Current Window Pointer” (ECWP), to be used in conjunction with the prior art window pointer. According to the present invention, the new window pointer ECWP can be used to override the prior art window pointer in dictating from which register window the operands stipulated by the instructions to be executed are sourced/sinked. Consequently, using the method and apparatus of the invention, the number of spills to memory is reduced, the number of instructions required is decreased, resources are used more efficiently, and costly dependency problems and RAW (read-after-write) stalls are prevented.

  • Patent number: 6203320
    Abstract: An electrically operated toothbrush and method for cleaning teeth and stimulating gums is provided. The toothbrush includes a handle, a brushhead connected to the handle having a plurality of hollow filament bristles, passageways through the handle and brushhead for transporting fluid such as water into and through the hollow filament bristles, an electrical energy source in the handle and a vibratory element for imparting a pulsation to the fluid being transported.

  • Patent number: 6138315
    Abstract: A unitarily constructed toothbrush is provided including a head with bristles unitarily molded therewith, a handle and a neck, all being formed of an identical plastic material. Dispersed throughout the plastic material is at least one anti-microbial active compound such as a halogenated hydrocarbon, a quaternary ammonium salt or combinations thereof. Preferably the plastic material is a low density polyethylene. Toothbrushes of the present invention inhibit the growth of bacteria and other micro-organisms thereby avoiding the possibility of infecting oral gums.
