Two control knobs for a heating/cooling system. The left knob controls the temperature while the right controls the fan speed. A control knob is a rotary device used to provide manual input adjustments to a mechanical/electrical system when grasped and turned by a human operator, so that differing extent of knob rotation corresponds to different desired input.
The first-generation Encore is a restyled first-generation Chevrolet Trax, and shares the same styling with the European Opel/Vauxhall Mokka.It debuted at the 2012 North American International Auto Show in Detroit on January 10, 2012, [7] and went on sale at the end of 2012.
The 322 Fireball V8 in a 1956 Buick Century. Buick's first generation V8 was offered from 1953 through 1956; it replaced the Buick straight-eight.While officially called the "Fireball V8" [1] by Buick, it became known by enthusiasts as the "Nailhead" for the unusual vertical alignment of its small-sized valves (Originally it was known to hot-rodders as the "nail valve", because the engine's ...
Therefore, this was a safety hazard: If the switch changed from Run to Accessory and the vehicle was involved in an accident, it would no longer have power to release the airbags, and it would be difficult for the driver to steer and brake. [12] General Motors was aware of this potential problem, and held meetings about it, as early as 2005. [13]
The Twilight Sentinel system uses a photoelectric cell to measure ambient light levels. This cell is typically mounted on the dashboard of the vehicle. [7] The system is designed to activate the vehicle's exterior lights when the ambient light falls below a certain threshold, typically corresponding to twilight conditions.
Ceramic cleats, which were block-shaped pieces, served a purpose similar to that of the knobs except that cleats were generally used in places where the wiring was surface mounted. Not all knob and tube installations utilized cleats. Ceramic bushings protected each wire entering a metal device box, when such an enclosure was used.
A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952.
In most applications the tuned circuit is part of a larger circuit which applies alternating current to it, driving continuous oscillations. If the frequency of the applied current is the circuit's natural resonant frequency ( natural frequency f 0 {\displaystyle f_{0}\,} below), resonance will occur, and a small driving current can excite ...
