Title: Directly actuated gaseous fuel injection valve with a movable nozzle
Inventor: MARK RANDALL
IPC: F02M51/06
Filed: 2002-10-09
Abstract: A directly actuated fuel injection valve is provided for injecting a gaseous fuel into a combustion chamber. The fuel injection valve comprises a valve body with a fuel cavity supplied with fuel from a fuel inlet passage. A nozzle associated with one end of the valve body comprises at least one nozzle orifice through which the gaseous fuel is injectable into the combustion chamber. In relation to the valve body, the nozzle is movable between a closed position, wherein the nozzle is seated against a sealing surface to provide a boundary between the fuel cavity and the one nozzle orifice(s), and an open position, wherein the nozzle is spaced apart from the sealing surface. A spring biases the nozzle in the closed position, and an actuator is operable to move the nozzle to the open position against the bias of the spring. A method is also provided for operating the disclosed injection valve to inject gaseous fuel into a combustion chamber by moving a nozzle relative to the valve body.

Title: Network node failover using failover or multicast address
Inventor: KASHYAP VIVEK
IPC: H04L12/18
Filed: 2002-07-26
Abstract: Failover of network nodes is disclosed. A first node joins a multicast group (102). The joining is performed by performing one of three actions (104).  First, a failover address is associated with the first node, and the first node effectively joins the group having this address as a multicast address.  Second, a multicast address is associated with the first node. Third, a switch' s multicast port is mapped to a first node port. Upon failure of the first node (106), one of three actions is performed. If the joining associated the failover address, this is associated with a second node, and the second node effectively joins the group (114). If the joining associated the multicast address, the second node joins the group and this address is associated with the second node (110). If the joining mapped the switch's multicast port, this port is remapped to a second node port (112).
