The binary cam is a design for the pulley system of a compound bow. Craig Yehle, director of research and development at Bowtech Archery, received a patent [ 1 ] for the design on December 11, 2007. Bowtech started equipping its bows with the new cam design in the 2005 model year.
Some pulley systems use a single cam at the bottom of the bow and a round idler wheel at the top of the bow instead of two identical cams. This design eliminates the need for a separate control cable and instead uses a single long string that begins at the cam on the bottom of the bow, travels over the wheel on top, and back to the bottom cam.
For twin-cam or DOHC engines, VCT was used on either the intake or exhaust camshaft. (Engines that have VCT on both camshafts are now designated as Ti-VCT.↓) The use of variable camshaft timing on the exhaust camshaft is for improved emissions, and vehicles with VCT on the exhaust camshaft do not require exhaust gas recirculation (EGR) as retarding the exhaust cam timing achieves the same ...
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.
A single dwell linkage takes advantage of the behavior of a link with a stationary revolute (hinge) or prismatic (sliding) joint and its interaction with special coupler curves. There are two methods of producing a single-dwell: arc-based and linear-based. An arc-based single dwell linkage uses the approximation of a circular arc.
Cam timers don't have the greater degree of flexibility that CPU-based controllers provide. As well as offering more wash program variations, a CPU based washing machine controller can respond to malfunctions, automatically initiate test cycles, reducing manufacturing costs, and provide fault codes in the field, again reducing repair costs, and ...

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 ...
