Body cameras have a range of uses and designs, of which the best-known use is as a police body camera. Other uses include action cameras for social and recreational (including cycling ), within the world of commerce , in healthcare and medical use, in military use, journalism , citizen sousveillance , and covert surveillance .
The cam can be seen as a device that converts rotational motion to reciprocating (or sometimes oscillating) motion. [clarification needed] [3] A common example is the camshaft of an automobile, which takes the rotary motion of the engine and converts it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
An S-cam is part of a braking system used in heavy vehicles such as trucks and wheeled machinery. It consists of a shaft, usually around 4 to 25 inches long, turned at one end by means of an air-powered brake booster and lever with an S-shaped cam at the wheel end. Turning the shaft pushes the brake shoes against the drum, producing friction.
A camshaft operating two valves. A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion.Camshafts are used in piston engines (to operate the intake and exhaust valves), [1] [2] mechanically controlled ignition systems and early electric motor speed controllers.
The 1966 Pontiac OHC Six engine was the first US mass-produced vehicle to use a timing belt, [21] [22] while the 1966 Fiat Twin Cam engine was the first mass-produced engine to use a timing belt with twin camshafts. Carmakers began to adopt timing belts in the 1970s and compared to timing chains are less expensive, smaller, lighter, quieter ...
In automotive electronics, body control module or 'body computer' is a generic term for an electronic control unit responsible for monitoring and controlling various electronic accessories in a vehicle's body.
A SnorriCam (also chestcam, body mount/bodymount, or bodycam) [1] is a camera device used in filmmaking that is rigged to the body of the actor, [2] with the camera facing the actor directly so that they appear in a fixed position in the center of the frame.
Some OHC engines employ short rocker arms, also known as fingers, in which the cam lobe pushes down (rather than up) on the rocker arm to open the valve. On this type of rocker arm, the fulcrum is at the end rather than the middle, while the cam acts on the middle of the arm. The opposite end opens the valve.
