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.

Two buttons passing through covers to the recesses enables contact with the two arc-rings causing each projecting pin to withdraw from the inner rod when pushed. When released, each button disengages from the two-arc rings causing the projecting pin to slide into a hole in the inner rod to prevent movement of the inner rod. A spring may be used to bias the two arc-rings into engagement with the inner rod.

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.
