A pressure sensor will detect an early start and the loudspeakers provide the runners with the sound from the starter all at the same time. Starting blocks are a device used in the sport of track and field by sprint athletes to brace their feet against at the start of a race so they do not slip as they stride forward at the sound of the starter ...
The study showed that non-sprinters ran with an inefficient gait for the maximal speed trial while all groups ran with energetically efficient gaits for the distance trial. This indicates that the development of an economical distance running form is a natural process while sprinting is a learned technique that requires practice.
Although rail vehicles occasionally do use drives without sensors, most need a rotary speed sensor for their regulator system. The most common type is a two-channel sensor that scans a toothed wheel on the motor shaft or gearbox which may be dedicated to this purpose or may be already present in the drive system.
To ensure that the sprinter's torso triggers the timing impulse at the finish line rather than an arm, foot, or other body parts, a double Photocell is commonly used. Times are only recorded by an electronic timing system when both of these Photocells are simultaneously blocked. Photo finish systems are also used at some track and field events.
Sprint cars do not utilize a transmission but have an in-or-out gearbox and quick-change rear differentials for occasional gearing changes. As a result, they do not have electric starters (or even electrical systems other than a ignition magneto) and require a push to be started. The safety record of sprint car racing in recent years has been ...
Adaptive cruise control does not provide full autonomy: the system only provides some help to the driver, but does not drive the car by itself. [3] For example, the driver is able to set the cruise control to 55mph, if the car while traveling that speed catches up to another vehicle going only 45mph, the ACC will cause the car to automatically brake and maintain a safe distance behind the ...
In each wheel, most often on the inside of the valve, there is a battery-driven pressure sensor which transfers pressure information to a central control unit which reports it to the vehicle's onboard computer. Some units also measure and alert temperatures of the tire as well. These systems can identify under-inflation for each individual tire.
The Mercedes-Benz Sprinter is a light commercial vehicle built by Mercedes-Benz Group AG of Stuttgart, Germany as a large van, chassis cab, minibus, and pickup truck.In the past, the Sprinter had been sold under the Mercedes-Benz, Dodge, and Freightliner nameplates.
