Engineering Release Control
This activity coordinates the release of new product information and engineering changes to manufavturing. It provides a major checkpoint in the product cycle to assure that all necessary documentation is available, followed by release of this information to manufacturing and production. It produces the same outputs as design.

Design Analysis
Design Analysis is comprises all the calculations necessary to ensure a product design is optimised in terms of performance, materials used and costs. Analysing design for materials usage can involve carrying out out various forms of stress calculations. These may be basen on the elastic behaviour of materials, on plastic behaviour of materials or on a materials tendency to develop cracks. Parts and assembliesof parts may also be analysed for stress or deflectionsby finite element or finite difference techniques. Cost analysis may involve comparing design which exploit the properties of particular materials in particular ways. Performance analysis may include the evaluation of fluid flows in the spaces not filled by material and the evaluation of the vibrational behaviour of a product in response to different excitation frequencies.

Process Manufacturing
A substantial part of the processing ofthe raw material into product takes place with the material in fluid form; heat and pressure are often involved. Examples occur in petrochemical plants, pharmaceuticals , foods manufacture, paper and glass manufacture. The final stage of process manufacturing systems often involve discrete production methods because the fluid may be canned or bottled into individual containers or the product itself becomes solid, as with gas.

Proximity Detectors
Proximity detectors record the presence of an objective without making physical contact. Proximity detectors are of two types; inductive for detecting the proximity of metals, capacitive for detecting both metals and non-metals.
