External Device Monitor (EDM). The device issuing the OSSD signals may have an EDM input. The EDM is used to verify that the controlled device (safety relay) did indeed open when the OSSD signals were dropped. The safety relay has normally closed contacts, which close when the relay is de-energized, thereby turning on the EDM input.
A framework to define and measure the electrical parameters during an EDM operation directly on inter-electrode volume with an oscilloscope external to the machine has been recently proposed by Ferri et al. [21] These authors conducted their research in the field of μ-EDM, but the same approach can be used in any EDM operation. This would ...
SprutCAM X is a high-level Computer-Aided Manufacturing software that provides off-line features for programming of various CNC machines used for cutting, wire electrical discharge (EDM), 2, 3, and multi axial (CNC Swiss-Type Lathe) machining. The program was developed by SprutCAM Tech Ltd based in Limassol, Cyprus. [1]
Another is the threat of packet access to the network segments hosting SCADA devices. In many cases, the control protocol lacks any form of cryptographic security, allowing an attacker to control a SCADA device by sending commands over a network. In many cases SCADA users have assumed that having a VPN offered sufficient protection, unaware ...
Most total stations use purpose-built glass prism (surveying) reflectors for the EDM signal. A typical total station can measure distances up to 1,500 meters (4,900 ft) with an accuracy of about 1.5 millimeters (0.059 in) ± 2 parts per million.
Radia Client Automation software is an end-user device (PC and mobile device) lifecycle management tool for automating routine client-management tasks such as operating system deployments and upgrades, patch management, application software deployment, application use monitoring, security, compliance, and remote system management.
Tempest for Eliza is a program that uses a computer monitor to send out AM radio signals, making it possible to hear computer-generated music in a radio. Video eavesdropping demo at CeBIT 2006 by a Cambridge University security researcher; eckbox – unsuccessful or abandoned attempt in spring 2004 to build an open-source Van Eck phreaking ...
A video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor. Direct Access Storage Device (DASD) A mainframe terminology introduced by IBM denoting secondary storage with random access, typically (arrays of) hard disk drives.
