Electrical equipment part of the distribution system in a large building. Electrical equipment includes any machine powered by electricity. It usually consists of an enclosure, a variety of electrical components, and often a power switch. Examples of these include: Lighting; Major appliance; Small appliances; IT equipment (computers, printers etc.)
When an electronic product is thrown away after its useful life is over, it produces electronic trash, or e-waste. E-waste is produced in vast quantities as a result of the consumption-driven society and the quick development of technology. [5] In the US, the United States Environmental Protection Agency (EPA) classifies e-waste into ten ...
Academic enquiry into the product lifetimes of electrical and electronic equipment was undertaken in 2000 by Cooper and Mayers [21] who conducted household interviews and focus groups to establish the age at discard (actual product lifetime) and expected lifetimes for 17 products. Since this study, work has been undertaken by other academics ...
Equipment that generates process or space heat and electric power, of a size useful for a single building. microcontroller A microprocessor integrated with memory and input/output circuits, useful for embedded control. microelectromechanical systems An electromechanical system of microscopic size; they may be sensors or actuators. microelectronics
The life support system of a surface saturation accommodation facility provides breathing gas and other services to support life for the personnel under pressure. It includes the following components: [ 12 ] Underwater habitats differ in that the ambient external pressure is the same as internal pressure, so some engineering problems are ...
Energy harvesting (EH) – also known as power harvesting, energy scavenging, or ambient power – is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, also known as ambient energy), then stored for use by small, wireless autonomous devices, like those used in wearable electronics, condition ...
‘Electrical and electronic equipment’ in turn has been defined to mean equipment which are dependent on electric current or electro-magnetic field in order to become functional." [24] A major concept presented in theses rules is the idea of extended producer responsibility (EPR). Producers of electronic products must implement EPR in order ...
This is especially useful in medical equipment where the signals from a low-voltage sensor circuit (usually battery-powered) in contact with a living organism must be electrically isolated from any possible electrical failure in a recording or monitoring device operating at potentially dangerous voltages. An optoisolator also lets information ...
