Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. [1] These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called BIPV ). [ 2 ]
Rooftop mounted systems are small compared to utility-scale solar ground-mounted photovoltaic power stations with capacities in the megawatt range, hence being a form of distributed generation. A comprehensive life cycle analysis study [3] showed that rooftop solar is better for the environment than utility-scale solar. [4]
The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

Mount Signal 3 – a 328 MW DC (254 MW AC) solar power station using photovoltaics on 2,000 acres (810 ha) completed in July 2018. American solar PV manufacturer First Solar provided its Series 4 thin-film solar panels for the project, and NEXTracker supplied its NX Horizon smart solar tracker systems.
A Skid mount is a popular method of distributing [1] and storing machinery [2] and usually-stationary equipment for the military and industry on its own or with other units as part of a modular system (modular process skid). The machinery at point of manufacture is permanently mounted in a frame or onto rails or a metal Pallet. The equipment ...
A rail system mounted on top of a SIG SG 550 A dovetail rail on a rifle receiver for mounting a sight. A rail integration system (RIS; also called a rail accessory system (RAS), rail interface system, rail system, mount, base, gun rail, or simply a rail [1]) is a generic term for any standardized attachment system for mounting firearm accessories via bar-like straight brackets (i.e. "rails ...
NATO Accessory Rail (STANAG 4694) The NATO Accessory Rail (NAR), defined by NATO Standardization Agreement (STANAG) 4694, is a rail interface system standard for mounting accessory equipment such as telescopic sights, tactical lights, laser aiming modules, night vision devices, reflex sights, foregrips, bipods and bayonets to small arms such as rifles and pistols.
Standards for alarm systems, installation and monitoring, are standards critical for ensuring safety, [1] reliability, [2] and interoperability. [ 3 ] [ 4 ] Various standards organizations, both international and regional, develop these guidelines and best practices.
