The simplest routing problem, called the Steiner tree problem, of finding the shortest route for one net in one layer with no obstacles and no design rules is known to be NP-complete, both in the case where all angles are allowed or if routing is restricted to only horizontal and vertical wires. [1] Variants of channel routing have also been ...
SolidWorks (stylized as SOLIDWORKS) is a brand within Dassault Systèmes that develops and markets software for solid modeling computer-aided design (CAD), computer-aided engineering (CAE), 3D CAD design, collaboration, analysis, and product data management. [2] The company introduced one of the first 3D CAD applications designed to run on a ...
Cable lacing is a method for tying wiring harnesses and cable looms, traditionally used in telecommunication, naval, and aerospace applications. This old cable management technique, taught to generations of lineworkers , [ 1 ] is still used in some modern applications since it does not create obstructions along the length of the cable, avoiding ...
ANSI/TIA-568 is a technical standard for commercial building cabling for telecommunications products and services. The title of the standard is Commercial Building Telecommunications Cabling Standard and is published by the Telecommunications Industry Association (TIA), a body accredited by the American National Standards Institute (ANSI).
Cables usually are secured with special fittings where they enter electrical apparatus; this may be a simple screw clamp for jacketed cables in a dry location, or a polymer-gasketed cable connector that mechanically engages the armour of an armoured cable and provides a water-resistant connection.
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
Single Cable Router (SCR) - a down-conversion device for the radio data link. It converts RF signal from a satellite dish or TV antenna to the user-defined IF channel. Usually, many SCRs are connected to a single coaxial cable - each converting to a separate IF channel. The entire system referred to as Single Cable Distribution.
The cables can be rigged in several configurations. There are two classes; High lead logging, in which a simple loop of cable runs from the yarder out through pulley blocks anchored to stumps at the far end of the cut. Skyline, in which a carriage, pulled by hauling cables, runs along a skyline cable, providing vertical lift to the logs.
