7069 results about "Pedestrian" patented technology

A pedestrian is a person travelling on foot, whether walking or running. In modern times, the term usually refers to someone walking on a road or pavement, but this was not the case historically. The meaning of pedestrian is displayed with the morphemes ped- ('foot') and -ian ('characteristic of'). This word is derived from the Latin term pedester ('going on foot') and was first used (in English language) during the 18th century. It was originally used, and can still be used today, as an adjective meaning plain or dull. However, in this article it takes on its noun form and refers to someone who walks.

Emergency vehicle traffic signal preemption system

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.

Spring stiffness adjustable tuning quality damper

The invention specifically relates to a mass tuned vibration reducer used for controlling the vibration of an aerobridge in the airport, a large-span pedestrian bridge, a port trestle, high-rise buildings and the related structures. The mass tuned vibration reducer comprises a mass block, a spring, a damper and a base; wherein, the spring can be a spiral spring, a disc spring or a plate spring, and the end part of the spring is provided with a rigidity regulating device. The mass tuned vibration reducer can successfully realize the regulation on the natural frequency of a TMD system under the condition of needing not to assemble and disassemble the TMD since the end part of the spring is provided with the rigidity regulating device, so as to simplify the difficulty of regulation work, avoid the waste of manpower and materials and greatly reduce the construction cost. Meanwhile, the natural frequency and the damping of the system can be regulated in an optimized way under the condition of needing not to assemble and disassemble the TMD, thereby better exerting the vibration absorption performance of the mass tuned vibration reducer, ensuring safety and stableness of the pedestrians and vehicles on the large-span bridge and the thin and high building, contributing to prolonging the service lives of the thin and high building and the bridge, and having remarkable economic and social benefits.
