  • Publication number: 20050180326
    Abstract: A system and method for providing services such as Wake-on-LAN and PXE Boot services to a multi-subnet network system which includes router and/or firewalls between different subnets. This is accomplished by using a peer computer to provide the service when performing such service is required to be transmitted across the router and/or firewall. That is, the system determines whether the service is required to go across the router and/or firewall, and, if so, to identify a computer (a peer computer) which is located on the appropriate subnet, then deliver the service to that peer computer (if necessary) and have that peer computer perform the selected service, such as Wake-on-LAN.

  • Patent number: 6845760
    Abstract: An apparatus and method for improving the transient response of a spark-ignited fuel-injected internal combustion engine is disclosed. This is accomplished by employing one or more novel capillary fuel injectors. These devices are port fuel injectors modified by inserting one or more relatively small diameter heated tubular capillaries between the fuel line and a conventional injector. Sufficient heating can be produced so that flash vaporization occurs as the fuel exits the injector. The heaters are turned on using control algorithms that can be based on exhaust gas oxygen concentration, load on the engine, and accelerator pedal position.
