Originally designed by the US Depanment of Defence so that a communication network could withstand a nuclear war and serve military institution worldwide. the Internet was first known as the ARPANet. A system of linked computer networks. international in scope. that facilitates data communication services such as remote login, web surfing. file transfer. electronic mail, fmd newsgroup
Any program. operation or device that transters data to or from a computer and 10 or from a peripheral device. Tbe transfer of data to and from thc processor to memory, expansion slots and to tbe motherboard is also known as I/O
Information Technology -refers to the broad range of technologies and applications Ihal suppon the creation. processing, lransmission, storage and management of digital information. IT includes hardware systems such as computers and network equipment, as well as software applications that run on computers
A cross-platform programming language from Sun Microsystems that can be used to create animations and interactive features on World Wide Web pages. Java programs are embedded into HTML documents. Java is an interpreted language. This means that il is wrinen for a piece of software thai then interprets the code for the hardware/operating system. The Java Virtual Machine is the piece of software that interprets lava for different platforms
A Local Area Network is a communications network Ihat serves users within a confined geographical area. usually contained within one or more floors of an entire building complex

A flat metal part which has a place to mount a semiconductor die llnd leads which can accept bond wires to connect 10 the die. The principal componem of many semiconduclor packages
The engineering of integrated mechanical-optical-electronic-software systems for examining natural objects and materials. human artifacts and manufacturing processes. in order to detect defects and improve quality, operaling efficiency and the safety of both producls and processes. It is also used to control machines used in manufacturing
The au:omated process of visually inspecting. a component or assembly for defects and/or measurement crileria using machine vision technology
Equipment or process used to produce a measurement
Unit of length. 1/1000 mm
Irrelevant or meaningless data resulting from various causes unrelated to the prime application requiremenls. In Machine Vision. noise is caused by varying ambient light (e.g. sun-light. fluorescent lubes providing environmemal lighting), dirt on the widget, optics or light source, as well as the usual sources of noise in electronics I;lquipment: eanh loops. EM radiation, capacitative coupling.. induction, ctc.

Sales Representatives A processing device. either an algorithm, or actual hardware, whose design was inspired by the design and functioning of animal bmins and components thereof. Most neurn! networks have some sort of “training” rule whereby the weights of connections are adjusted on the basis of presented patterns. In other words, neural networks “Ieam” from examples and exhibit some structural capability for generalisation
Machine makers or automation companies which produces handlers/machines to perform testing, vision and/or taping. Our vision systems are usually integrated onto their machines as part oflhe equipment to handle the device/unit inspection.
A polymcr~based board containing conductor tracks, which becomes an electrical circuit when components are attached/mounted and soldered 10 it. The components can either be soldered 10 the conductor tracks, or interconnected by means of wircbonds (chip and wire) or by solder bumps (flip chip)
A handheld device that combines computing, telephone/fax and networking features. A typical rDA can function as a cellular phone, fax sender, and personal organiser. Many PDAs incorporate handwriting and/or voice recognition features. PDAs also are called palmtops, handheld computers, and pocket computers
The center-to-center distance between adjacent leads on a pack.age
Smallesl addressable portion ora digital image. Within the boundaries ofa given pixel, the intensity and colour can be considered constant
The degree ofspread or deviation between each measurement of the same part or feature
An optical device with two or more non-parallel. polished faces from which light is either reflected or refracted. Often used to redirect light as in binoculars

Image-processing operation which converts a grey-scale image into a binary image, be setting all pixels above a defined value to white and all others to black. Despite its simplicity and intuitive appeal, fixed-value thresholding is unreliable and should alwa)’s be preceded by appropriate tiltering and careful control of the illumination level
