Button less Bump Sensor [C , Atmel AVR]

Team project 1 Documentation Report 3 (by Sky)Report 5 (by Steve-incomplete version) 1. PROBLEM DESCRIPTION There are several specifications to be met in designing the product. They are:– The product must be battery powered and only standard alkaline can be used.– The batteries must last for 3 months– The device must be able detect phone tone to set password and also to deactivate the alarm– The device must be button less.– The device must be within the size restriction of 70mm x 70mm x 70mm– The total cost of the product must come in under $100. With the advancement in modern technology, it would be a great way to build a portable security device to help you in times of event when someone tired to steal away your unattended item. The objective of building this project is to provide a convenient way of bringing a portable security unit with you all the time. The advantages of building this project are that it is a small and portable device which can be easily carry with you. It will provide security for your unattended item when attached. Alarm will be trigger immediately when the item is being remove or taken away.

Image Processing II [Matlab Image Processing][Flash]

elec4600 – Signal and Image Processing.There were 5 Assignments all together in this subject.Shown below is 2 of the more interesting assignments. 1. Detecting Road Lines with Hough Transform and some custom filtering Result from Hough Transform Algorithm.Lines are then selected based on some distinctive characteristic. Remaining lines are then used to find the vanishing point.The vanishing point is then used to do more line selection filtering.Which gives the final result seen on the right below. 2. Blood Vessel Size – (Uses the Snake Method). Detection from 10 still imagesUsing the snake or rubber band idea,where a shrinking band is used to wrapthe outer layer of the vessel ,and an expandingband is used to outline the inner layer of the vessel.This is repetitively implemented on 10 imagesof the blood vessel. which is then wrapped togetherto produced a short clip seen here in a flash file....

THESIS | [J2ME ] Mobile Phone Barcode Reader (internal camera)

{ THESIS POSTER. } Brief Description A one year duration thesis. The main goal was to make a barcode scanner utilizing the inbuilt camera. There were many ways in implementing this feature. The main idea i have decided on was as a stock management tool. Where home users to medium sized business such as those on ebay can use this tool to update the database in their computer automatically. Basically the user just need to capture the barcode on the product they are going to ship out or is sold and it will automatically update the database, more examples will be such as defect or a new product or if user wants to edit details of a certain product. This software is made with J2ME(JAVA) and runs on s60 and s40s. Currently trying to improve recognition on the s40 which has bad resolution and low memory. BaToo The main program is based on Batoo (Barcode tool kit) by Robert Adelmann, http://people.inf.ethz.ch/adelmanr/batoo/ Abstract The Mobile phone has evolved from being a simple communication device to become a multipurpose device with advanced features such as camera device, video capabilities, and mp3 player. Using the internal Camera Device we will implement the Barcode Scanner. This research is not intended to replace nor compete with the laser barcode scanners but instead to introduce a different variant of usage of the barcode and the camera device. A Mobile phone Barcode scanner, although slower in recognition speed provides better mobility, flexibility and simplicity. Targeting home users and home-based online business owners, this technology provides a better solution as all they need is to install a...

Udp based Chat Program [JAVA]

requires newest Java to run (1.5.0…)NETWORK PROGRAMMING [UdpJavaChat.rar]A java based chat program using the UDP protocol.The chat program consist of 3 separate entities.1-NameServer2-ChatServer3-ChatClient 1-NameServer serves as the centre to save and manage multiple ChatServer details.ChatClient first connects to NameServer to get details about the ChatServer they wishto connect to. 2-ChatServer servers as the centre to save and manage Chats between ChatClients. 3-ChatClients ,this is the user interface ,where the user chats with other ChatClientsconnected within the same ChatServer.

Organism growth visualisation [JAVA]

requires newest Java to run (1.5.0…)1 – Algorithms and Data structures [organism.rar]This assignment was basically trying to create a program (uses hash table system) that shows how an organism grows starting from a single cell. Further explanation of the use of the program and how the program works ,AFTER MY EXAMS haha so for now here is the sample of the program. with some sample organism rule.The program takes the rule and grows the organism in 2d . Also take note this is just a basic system as the growth of the organism is much more complex and butterfly transforms from a catterpillar and doesnt grow from a single cell lol. Any how check out my SuperButterfly it was a bonus question. and there was extra marks for flair.. so i went crazy with it haha.PLEASE read the README.TXT to see how to use my program. please email me or message me if u need help with running this program 😉...
