An emergency vehicle traffic light preemption system for preemption of traffic lights at an intersection to allow safe passage of emergency vehicles. The system includes a real-time status monitor of an intersection which is relayed to a control module for transmission to emergency vehicles as well as to a central dispatch office. The system also provides for audio warnings at an intersection to protect pedestrians who may not be in a position to see visual warnings or for various reasons cannot hear the approach of emergency vehicles. A transponder mounted on an emergency vehicle provides autonomous control so the vehicle operator can attend to getting to an emergency and not be concerned with the operation of the system. Activation of a priority-code (i.e. Code-3) situation provides communications with each intersection being approached by an emergency vehicle and indicates whether the intersection is preempted or if there is any conflict with other approaching emergency vehicles. On-board diagnostics handle various information including heading, speed, and acceleration sent to a control module which is transmitted to an intersection and which also simultaneously receives information regarding the status of an intersection. Real-time communications and operations software allow central and remote monitoring, logging, and command of intersections and vehicles.

When a node has to restart its control component, or a (e.g., label-switched path signaling) part of its control component, if that node can preserve its forwarding information across the restart, the effects of such restarts on label switched path(s) the include the restarting node are minimized. A node's ability to preserve forwarding information across a control component (part) restart is advertised. In the event of a restart, stale forwarding information can be used for an limited time before. The restarting node can use its forwarding information, as well as received label-path advertisements, to determine which of its labels should be associated with the path, for advertisement to its peers.

A hollow blade has an internal cooling passage, an open cavity situated at the free end of the blade and defined by an end wall extending over the entire end of the blade and by a rim. The blade includes cooling channels connecting the internal cooling passage and the outside face of the pressure side wall. The pressure side wall presents a projecting end portion whose outside face is inclined relative to the outside face of the pressure side wall. The cooling channels are disposed in the end portion, being parallel to the outside face of the end portion so that they open out into the tip of the end portion towards the free end of the blade.

In a thermal-type flow rate sensor, a mold material is formed to integrally cover a predetermined range including a circuit chip, connecting parts of connecting wires with a flow rate detecting chip and the circuit chip, and connecting parts of connecting wires with the circuit chip and a lead portion, to expose a part of the flow rate detecting chip to a measured fluid. The flow rate detecting chip is located in a groove portion of a support member to have a clearance with the groove portion and to form a cavity part inside a thin wall portion of the detecting chip. The cavity part communicates with an outside through a communicating portion that includes the clearance, and the clearance is blocked by a filler at least at a portion positioned in the predetermined range. Therefore, the filler prevents the mold material from entering the clearance in the mold forming.

A reducer of an electronic power steering apparatus is disclosed. The reducer of an electronic power steering apparatus aids the operation of a steering wheel by the driver by preventing a clearance from being caused by frictional wear between a worm and a worm wheel, by reducing rattle noise caused by backlash, and by minimizing the change in the clearance due to a change in torque.
