Overview AirPort debuted on July 21 1999 at the Macworld Expo in New York City with Steve Jobs picking up an iBook supposedly to give the cameraman a better shot as he surfed the Web The applause quickly built as people realized there were no wires The initial offering included an optional expansion card for Apple s new line of iBook notebooks plus an AirPort Base Station The AirPort card a repackaged Lucent ORiNOCO Gold Card PC Card adapter was later added as an option for almost all of Apple s product line including PowerBooks eMacs iMacs and Power Macs Only Xserves do not have it as a standard or optional feature The original AirPort system allowed transfer rates up to 11 Mbit s and was commonly used to share Internet access and files between multiple computers On January 7 2003 Apple introduced AirPort Extreme based on the 802 11g specification AirPort Extreme allows theoretical peak data transfer rates of up to 54 Mbit s and is fully backward compatible with existing 802 11b wireless network cards and base stations Several of Apple s desktop computers and portable computers including the MacBook Pro MacBook Mac Mini and iMac shipped with an AirPort Extreme 802 11g card as standard All other modern Macs have an expansion slot for the card AirPort and AirPort Extreme cards are not physically compatible AirPort Extreme cards cannot be installed in older Macs and AirPort cards cannot be installed in newer Macs The original AirPort card was discontinued in June 2004 On June 7 2004 Apple released the AirPort Express base station as a Swiss Army knife product It can be used as a portable travel router using the same AC connectors as on Apple s AC adapters as an audio streaming device with both line level and optical audio outputs and as a USB printer sharing device through its USB host port On January 9 2007 Apple unveiled a new AirPort Extreme 802 11 Draft N Base Station which introduced 802 11 Draft N to the Apple AirPort product line This implementation of 802 11 Draft N can operate in both the 2 4GHz and 5GHz ISM bands and has modes that make it compatible with 802 11b g and 802 11b a The number of Ethernet ports was increased to fourne nominally for WAN three for LAN but all can be used in bridged mode A USB port was included for printers and other USB devices The Ethernet ports were later updated to Gigabit Ethernet on all ports The styling is similar to that of the Mac Mini and Apple TV On January 15 2008 Apple introduced Time Capsule an AirPort Extreme 802 11 Draft N with an internal hard drive The device includes software to allow any computer running a reasonably recent version of Mac OS or Windows to access the disk as a shared volume Macs running Mac OS X 10 5 and later which includes the Time Machine feature can use the Time Capsule as a wireless backup device allowing automatic untethered backups of the client computer As an access point the unit is otherwise equivalent to an AirPort Extreme 802 11 Draft N with four Gigabit Ethernet ports and a USB port for printer and disk sharing On March 17 2008 Apple released an updated AirPort Express Base Station with 802 11 Draft N 2×2 radio All other features analog and digital optical audio out single Ethernet port USB port for printer sharing remained the same At the time it was the least expensive 99 device to handle both frequency bands 2 4GHz and 5GHz in 2×2 802 11 Draft N On March 3 2009 Apple unveiled AirPort Extreme and Time Capsule products with simultaneous dual band 802 11 Draft N radios This allows full 802 11 Draft N 2×2 communication in both 802 11 Draft N bands at the same time On October 20 2009 Apple unveiled the updated AirPort Extreme and Time Capsule products with antenna improvements the 5 8Ghz model resulting in wireless performance gains of both speed and range also stated is a resulting performance improvement time reduction on Time Capsule backups of up to 60 All current AirPort base stations and cards work with third party base stations and wireless cards that conform to the 802 11a 802 11b 802 11g or 802 11 Draft N networking standards It is not uncommon to see wireless networks composed of several types of AirPort base station serving old and new Macintosh Microsoft Windows and Linux systems Apple s software drivers for AirPort Extreme also support some Broadcom and Atheros based PCI Wireless adapters when fitted to Power Mac computers Due to the nature of Draft N hardware there is no assurance that the new model will work with 802 11 Draft N routers and access devices from other manufacturers Base stations An AirPort base station is used to connect AirPort enabled computers to the Internet each other a wired LAN and or other devices AirPort Original Graphite AirPort Base Station The original AirPort known as Graphite features a modem and an Ethernet port It employs a Lucent WaveLAN Silver PC Card as the Radio and uses an embedded AMD Elan processor It was released July 21 1999 The Graphite AirPort Base Station is functionally identical to the Lucent RG 1000 wireless base station and can run the same firmware Due to the original firmware locked limitations of the Silver card the unit can only accept 40 bit WEP encryption Later aftermarket tweaks can enable 128 bit WEP on the Silver card Aftermarket Linux firmware has been developed for these units to extend their useful service life A second generation model known as Dual Ethernet or Snow was introduced on November 13 2001 It features a second Ethernet port when compared to the Graphite design allowing for a shared Internet connection with both wired and wireless clients Also new was the ability to connect to America Online s dial up service feature unique to Apple base stations This model is based on Motorola s PowerPC 855 processor and contained a fully functional original Airport Card which can be removed and used in any compatible Macintosh computer AirPort Extreme Base Station AirPort Extreme Base Station The AirPort Base Station was discontinued after the updated AirPort Extreme was announced on January 7 2003 In addition to providing wireless connection speeds of up to a maximum of 54 Mbit s it adds an external antenna port and a USB port The antenna port allows the addition of a signal boosting antenna and the USB port allows the sharing of a USB printer A connected printer is made available via Bonjour s zero configuration technology and IPP to all wired and wireless clients on the network A second model M8930LL A lacking the modem and external antenna port was briefly made available but then discontinued after the launch of AirPort Express see below On April 19 2004 a third version marketed as the AirPort Extreme Base Station with Power over Ethernet and UL 2043 was introduced that supports Power over Ethernet and complies to the UL 2043 specifications for safe usage in air handling spaces such as above suspended ceilings All three models support the Wireless Distribution System WDS standard The model introduced in January 2007 does not have a corresponding PoE UL compliant variant An AirPort Extreme base station can serve up to 50 wireless clients at once and thus is more suitable for a corporate environment than the AirPort Express AirPort Extreme Base Station The AirPort Extreme was updated on January 9 2007 to support the 802 11a b g and Draft N protocols This revision also adds two LAN ports for a total of three It now more closely resembles the square shaped Apple TV and Mac Mini and is about the same size and half the height of the Mini The new AirPort Disk feature allows users to plug a USB hard drive into the AirPort Extreme for use as a network attached storage NAS device for Mac OS X and Microsoft clients Users may also connect a USB hub and printer The AirPort Extreme has no port for an external antenna On August 7 2007 the AirPort Extreme began shipping with Gigabit Ethernet matching most other Apple products On March 19 2008 Apple released a firmware update for both models of the AirPort Extreme to allow AirPort Disks to be used in conjunction with Time Machine similar to the functionality provided by Time Capsule On March 3 2009 Apple unveiled a new AirPort Extreme with simultaneous dual band 802 11 Draft N radios This allows full 802 11 Draft N 2×2 communication in both 802 11 Draft N bands at the same time On October 20 2009 Apple unveiled the updated AirPort Extreme Base Station with antenna improvements resulting in wireless performance gains of both speed and range Also stated is a

In the manufacture of consumer products, quality control is of utmost importance. In most instances where manual processes are involved, the individual who operates the machinery also performs this task. In injection molding, for instance, this means ensuring the correct orientation and quality of print on the manufactured parts and components. In manually operated equipment, this inspection process presents a challenging task because often, after prolonged hours of work, fatigued operators will insert labels inside the molding dies in improper orientation, resulting in rejected parts. In other cases, because of the heat in the molding process, if there is excess ink on the labeling equipment, the prints may be smeared or distorted. Machine operators occasionally miss or overlook quality issues. To alleviate this inspection and operation problem, it is now possible to incorporate vision systems which will ease the inspection task for the operators, allowing them to concentrate more on the manufacturing process. Vision systems provide means by which continuous and autonomous inspection can be achieved during production.
Computer vision techniques are increasingly being used as alternative methods to conventional inspection and monitoring applications, due to their simplicity and ease of set-up, relative insensitivity to ambient noise, noninvasive means of gathering information on objects without contact, marking or specimen preparations, and the potential for online applicability.1″3 Machine vision has continued to play a major role in the integration of automated manufacturing, both from a quality and inspection perspective to more advanced applications such as motion control and robot guidance. For example casting mould,mold making,plastic injection mold etc.The role of machine vision in providing solutions to manufacturing automation has been recognized by both researchers and engineers in industry.
In the plastics manufacturing industry, vision applications have been used mainly to inspect the quality of molded parts, especially for missing features or badly formed sections. Although fairly automated, the plastics molding industry still has a large component of its operations carried out manually, especially for medium- and low-volume rates of production. For instance, the placement of print template or metallic parts to be included in the finished product is still done manually. Under such circumstances, it is possible to have a wrongly inserted print template which would result in the rejection of the part.
In some cases, due to process variations, a particular plastic part may posses a smudged or faint print. These latter quality problems are often not easy to detect in the processing of plastics. In this paper, the application of a smart vision system in the automatic detection of poor or improperly oriented print templates is presented. The method used to detect improper orientation is based on edge detection and feature identification. More advanced algorithms like segmentation, template matching, and character recognition are utilized for ensuring proper print quality.
To achieve machine vision successfully, and implement the use of computer software, the viewing area must be represented in digital form.The purpose of image acquisition therefore is to capture the optical data and change it to a form that will facilitate convenient and efficient processing using a computer. An image is typically embedded within a viewing area covered by the video capturing mechanism or sensor. The most common type of capturing mechanism is the charged coupled device (CCD). When a light source hits an object, it is reflected to the sensor through appropriate lenses. The photons cause electrical charges to be created in the CCl), thus generating analog signals on a 2-D array. The intensity of the charge at each discrete point in the 2-D array is proportional to the photon energy impinging on that point, determining the brightness or intensity of the light. Therefore a typical optical image system is a continuous 2-D function, h(x,y) whose value at any pair of spatial coordinates represented by the Cartesian coordinate system (x,y) is the intensity of light at that point. The continuous function h(x,y) must be quantized (or digitized) so that it can be easily processed by computer.
The most common method of digitization is a combination of spatial and amplitude quantization in which the viewing area is divided into a matrix of m by n cells or pixels: m and ç are integers. The image is sampled at these discrete points in the viewing area. Each pixel is then assigned a numerical value that is a digital representation of the initial analog value. h(x,y). through the analog-to-digital (A/D) conversion system.The numerical value will depend on the bit resolution of the A/D converter which in turn determines the number of gray-scale levels in which the image can be represented. Therefore the new image data, I(m.n). will have values between O (dark or lowest intensity) and 2^sup r^-l. where r is the bit resolution of the A/D converter.The acquired image must then be filtered to remove any noise, and enhanced for analysis.This stage is known as processing. There are five common types of operational approaches for primary processing of pixels.
