This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...
After the public introduction of the concept cars, Chevrolet started constructing several camouflaged test mules of the Camaro which were manufactured by Holden costing about US$250,000 each. These vehicles were used for crash testing, test driving, and handling extreme weather conditions such as in Canada, Arizona, and Australia.
In 1960, Ohio State University's Communication and Control Systems Laboratory launched a project to develop driverless cars which were activated by electronic devices embedded in the roadway. Head of the project, Dr. Robert L. Cosgriff, claimed in 1966 that the system could be ready for installation on a public road in 15 years.
A less common type of dashpot is an eddy current damper, which uses a large magnet inside a tube constructed of a non-magnetic but conducting material (such as aluminium or copper). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. A common use of the eddy current damper is in balance scales.
The mix of fresh air and recirculated air can thus be adjusted to suit the needs of the building's occupants. Most systems will use motorized dampers to control the air mixing, and controlled by the building management system (BMS), or controls system. Typically as the fresh air and exhaust air dampers are driven from 0% open to 100% open, the ...
The first theoretical analysis and practical application of PID was in the field of automatic steering systems for ships, developed from the early 1920s onwards. It was then used for automatic process control in the manufacturing industry, where it was widely implemented in pneumatic and then electronic controllers. The PID concept has been ...
The Fiat 500 is an A-segment city car manufactured and marketed by the Fiat subdivision of Stellantis since 2007. It is available in hatchback coupé and fixed-profile convertible body styles, over a single generation —with an intermediate facelift in Europe with the 2016 model year.
Yaw damper between cars of an E259 series EMU operated by JR East in Japan, June 2009 Another type of yaw damper, installed on a Meitetsu 2200 series bogie. A yaw damper is a transverse mounted shock absorber used to prevent railcars and locomotives from swaying excessively from side to side.
