A radar speed gun, also known as a radar gun, speed gun, or speed trap gun, is a device used to measure the speed of moving objects. It is commonly used by police to check the speed of moving vehicles while conducting traffic enforcement , and in professional sports to measure speeds such as those of baseball pitches , [ 1 ] tennis serves , and ...
The Whippet is a British breed of medium-sized dog of the sighthound type, related to the larger Greyhound and the smaller Italian Greyhound.Aside from size differences, the Whippet closely resembles these two breeds and is sometimes referred to as the "miniature Greyhound" or, colloquially, as "the poor man's racehorse."
The Medium A was designed by Tritton's chief engineer, William Rigby. The Whippet was a successful design and proved effective but suffered from a lack of power, complex steering and unsprung suspension. Wilson, now a Major, decided he could by himself develop a better tank as replacement: the 'Medium Tank Mark B'.
A GPS map showing speed camera POI information overlaid onto it. To avoid detection or prosecution, drivers may: Brake just before a camera in order to travel past its sensor below the speed limit. This is, however, a cause of collisions. Or brake suddenly, which results in rear-end crashes. [11]
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.
The original function of the Italian greyhound was to hunt hare and rabbit; it is capable of bursts of speed up to 60 km/h (37 mph). [14] Although assigned to the sighthound or hare-coursing groups by the Fédération Cynologique Internationale and the Ente Nazionale della Cinofilia Italiana, [ 2 ] [ 3 ] the Italian Sighthound is – as it was ...
The indicated speed must not be more than 110 percent of the true speed plus 4 km/h (2.5 mph) at specified test speeds. For example, at 80 km/h (50 mph), the indicated speed must be no more than 92 km/h (57 mph). The standards specify both the limits on accuracy and many of the details of how it should be measured during the approvals process.
Lure coursing is a sport for dogs that involves chasing a mechanically operated lure. Competition is typically limited to dogs of purebred sighthound breeds. The AKC has a pass/fail trial for all breeds called the Coursing Ability Test (CAT) and a timed 100 yard dash called Fast CAT where the dog's speed is converted to points.
