Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems. Some objectives of building ...
The Wedgewood stove was manufactured in Newark, California, originally by the James Graham Manufacturing Company and later as a division of Rheem. Gas ranges and stand-alone ovens marketed under the Wedgewood brand were particularly popular in the Western United States in the early and middle of the 20th Century.
A kitchen hood in a small apartment. A kitchen hood, exhaust hood, hood fan, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen.
Air streams are mixed to save energy and improve energy efficiency by partially recirculating conditioned air.. The most common application for an air-mixing plenum is the mixing of return air (or extract air) with fresh air to provide a supply air mixture for onward distribution to the building or area which the ventilation system is serving.

A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction).
AC electric motors can be run in fixed-speed operation determined by the number of stator pole pairs in the motor and the frequency of the alternating current supply. AC motors can be made for "pole changing" operation, reconnecting the stator winding to vary the number of poles so that two, sometimes three, speeds are obtained.
A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [ 1 ] [ 2 ] [ 3 ] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet.
MagneRide is an automotive adaptive suspension with magnetorheological damper system developed by the Delphi Automotive corporation, [1] [2] that uses magnetically controlled dampers, or shock absorbers, for a highly adaptive ride.
