Optical proximity correction (OPC) is a photolithography enhancement technique commonly used to compensate for image errors due to diffraction or process effects. The need for OPC is seen mainly in the making of semiconductor devices and is due to the limitations of light to maintain the edge placement integrity of the original design, after ...
An SS7 point code is an address for the SS7 telephone switching system. It is similar to an IP address in an IP network. It is a unique address for a node (Signaling Point, or SP), used in MTP layer 3 to identify the destination of a message signal unit (MSU).

MAPS Minimum Aviation Performance Standards MATS Manual of Air Traffic Services: MB Marker beacon: MBC Main Base Check MCAS Maneuvering Characteristics Augmentation System: Held responsible for Boeing 737 MAX groundings: MCBF Mean cycles between failures MCC
Duration: Developing flight controls with flight test will extend the duration of an aircraft development program. Using HIL simulation, the flight controls may be developed well before a real aircraft is available. Safety: Using flight test for the development of critical components such as flight controls has a major safety implication ...
The OPC Data Access Specification is the first of a group of specifications known as the OPC Classic Specifications. [1]OPC Data Access is a group of client–server standards that provides specifications for communicating real-time data from data acquisition devices such as PLCs to display and interface devices like Human–Machine Interfaces (HMI), SCADA systems [2] and also ERP/MES systems.

OPC Servers can be written for anything from getting the internal temperature of a microprocessor to the current temperature in Monument Valley. [citation needed] Once an OPC Server is written for a particular device, it can be reused by any application that is able to act as an OPC client. OPC servers can be linked and communicate to other ...
OPC Unified Architecture (OPC UA) is a cross-platform, open-source, IEC62541 standard for data exchange from sensors to cloud applications developed by the OPC Foundation. Distinguishing characteristics are: [ 1 ]
The OPC Foundation enhanced the range for certification of OPC product to meet the increasing demand for reliable functionality and insured interoperability. The self-certification using the ComplianceTestTool (CTT) and the participation at an Interoperability Workshop (IOP) are now enhanced with a Certification in an independent test facility.
