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.

A system for managing wish list items from a plurality of online merchants is provided. The system includes a memory, processor and item management module executed by the processor. The memory stores data regarding the wish list items that have been selected by a user while browsing online merchant websites.

A method and apparatus for providing a storm door mortise lock that prevents lockout with a lock body having opposed side plates and a cam in between the side plates, the cam being in operative interaction with a dead bolt assembly. The mortise lock body also may include one or more stops within the deadbolt assembly to limit the rotation of the cam and prevent a lockout situation. A thumb turn button and key cylinder are secured to opposite escutcheon plates. A spindle traverses from the key cylinder through the cam through hole and terminates in the mounting slot of the thumb turn button. Rotation of either the thumb turn button or the key cylinder turns the spindle and actuates the cam that actuates the dead bolt assembly.

An oar or scull is attached to the racing shell with an assembly that assures all motions required for rowing and restricts others. Over squaring and over feathering of the blade is prevented using stops which also provide positive feedback of blade orientation to the athlete and eliminate oarlock slap and rattle. Pulling on the oar handle inboard approximately 0.2 inches prior to squaring or feathering the blade moves the oarshaft outboard or inboard respectively, changing the leverage or load, at the completion of squaring or feathering. Normal rowing at the selected load is maintained with a steady outboard force of the oar handle. The oarlock is situated on the bow side of the vertical pin pulling the pin toward the bow during the propulsive phase of the rowing stroke. The vertical pin is supported by rigging which extends from the top and bottom of the vertical pin toward the stern. This rigging arrangement assures a stable pin that remains vertical because the restraining member is in tension toward the stern.
