Rain sensor on the windshield of a car. A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall.
From In-car Temperatures As High As The 130S To Rain, How Weather Impacts Nascar Races If you turn your car key or hit the start button and nothing happens, experts say the car battery is the most ...
Another type of tripped rollover occurs due to a collision with another vehicle or object. These occur when the collision causes the vehicle to become unstable, such as when a narrow object causes one side of the vehicle to accelerate upwards, but not the other. Turned down guard rail end sections have been shown to do this. A side impact can ...
An automatic trip is an action performed by some system, usually a safety instrumented system, programmable logic controller, or distributed control system, to put an industrial process into a safe state. It is triggered by some parameter going into a pre-determined unsafe state.
Roof crush is the failure and displacement of an automobile roof into the passenger compartment during a rollover accident. Every year approximately 10,000 Americans are killed in rollover accidents, accounting for about 30% of all light vehicle occupant fatalities. [1] The number of occupant injuries is significantly higher.
A rain roof is a second, newer roof that has been constructed over an existing roof that has failed, or which has inadequate slope to shed rain. Since such additional spaces may not be visible or accessible, the concealed void presents a particular hazard in firefighting operations, as a fire may develop or persist in such a space undetected.
Rain grooved road that can cause groove wander. Groove wander, similar to tramlining, is a lateral force acting on a vehicle's wheel resulting from the combination of rain grooves (grooves cut into roads to mitigate hydroplaning in light rain conditions) and contoured deformations in the road surface upon which the wheel runs.
The switch shown to the right is intended to disable an electric fuel pump in automotive applications. This functionality is required in some vehicle racing applications, since an electric fuel pump may otherwise continue operating after a collision or rollover. If the fuel line is broken or the vehicle is inverted, fuel may be spilled ...
