Customer relationship management(CRM) is a widely-implemented strategy for managing a company’s interactions with customers, clients and sales prospects. It involves using technology to organize, automate, and synchronize business processes—principally sales activities, but also those for marketing, customer service, and technical support. The overall goals are to find, attract, and win new clients, nurture and retain those the company already has, entice former clients back into the fold, and reduce the costs of marketing and client service. Customer relationship management describes a company-wide business strategy including customer-interface departments as well as other departments. Measuring and valuing customer relationships is critical to implementing this strategy.
A CRM system may be chosen because it is thought to provide the following advantages:

3D Pong takes MIT Pong to the next level with a 3D interface. At the heart of the project there is a hardware based 3D renderer. The renderer takes in a 3D model, specifically a sequence of colored triangles in a 3D space, and produces a 2D SVGA image. The view is controlled through a trackball mouse, which specifies rotations, translations and zoom. While the renderer can take in pre-built models stored in on-chip ROM, during gameplay a model of the current board is generated dynamically.
The project contains several high-level modules in addition to the renderer. A track-ball driver connects to the PS/2 interface and provide rotation, translation and zoom inputs, along with a possible lightsource input, to the renderer. A game-logic module provides ball and paddle coordinates to the game-model builder. The game-model builder turns the ball and paddle coordinates into a 3D model of the game field. The 2D image produced by the renderer is buffered in a double-buffer module which interfaces with the labkit SRAM. An SVGA module uses these buffered images to generate monitor outputs.
The renderer is pipelined, and is divided into several submodules. These include a rotator, a translator, a triangle shader, a projector, and a pixel-painter. The rotator module uses matrix multiplication to rotate triangle vertices about the origin. The translator module uses signed subtraction to recenter the points about a new origin. The shader module calculates a vector normal to the triangle's plain, then take a dot product with the light-source vector, in order to calculate the proper color for the entire triangle. The projector module, uses the z-coordinate of each point to rescale the x and y coordinates, based on a given lens focal length. Finally, the pixel painter enumerates the pixels in the interior of the triangle, storing their colors and z-coordinates to the buffer module.
The purpose of this project is to design an implement a laser pointer mouse. When doing a PowerPoint presentation or using the computer for any other occasion for which it is inconvenient to be sitting in front of it, users would like a way to control the computer remotely. The laser pointer mouse allows lecturers and presenters to point at the screen, and, with the press of a button, move the mouse cursor to the location of the laser, without ever touching the computer or mouse. A few more buttons allow the user to perform wirelessly transmitted left, right, and double clicks. Support for drawing over the screen, e.g. arrows and circles for increased presentation effectiveness, will be implemented as time permits. The system will be implemented in Verilog, and realized on the FPGA on the 6.111 labkit.

We will design and implement an image recognition system to identify fingerprints based on a given database. We will begin by inputting simple images and checking that the system accurately identifies those images. As the system is developed, more complex images can be used. The final stage of the project will involve identifying an individual's fingerprint based on standard points of identification used in common practice.
This project consists of a few stages. The initial stage will involve creating a database in memory for the image comparison. The next stage will be developing an interface between the camera and a RAM to store the image that needs to be identified. Once the image has been loaded into the system, it must be processed to select the appropriate characteristics for the comparison to the database. The processed image will then be compared to the images in the database to determine the quality of the similarities. The most similar image will be selected and presented to the user interface along with the quality of the identification.
The image processing will involve a series of filters in the spatial domain. There will be an edge-detection filter to sharpen the image, prior to binarization of the fingerprint. Another filter will select the unique components of the fingerprint. The database will contain the post-processed fingerprint information to minimize the size of the stored data. The database size will be limited to the memory of the labkit, which will be sufficient to demonstrate the functionality of the fingerprint matching system.
The work will be split into two components. Bashira will be responsible for interfacing the camera to the labkit, as well as managing the data storage in memory. Cheryl will implement the image processing to isolate the data for the analysis and the matching. Once the fingerprint recognition scheme is working, both team members will work to enhance the identification interface as time allows to create a visually appealing result.

This project implements a networked video surveillance system in digital logic. It allows a user to view video input from a remote camera on a VGA monitor by capturing camera data, encoding it, transmitting it wirelessly, and subsequently receiving, decoding, and re-displaying the data. To test the system, the project is divided into three main components: video capture/display, data encoding/decoding, and wireless transmission/reception. Each part is put through a comprehensive series of tests using Model Sim and simulated data. Once each component passes design and functional tests, all three components are then connected to transmit video data wirelessly

Instant messaging (IM) is a collection of technologies used for text-based communication between two or more participants over the Internet or other types of networks. Of importance is that online chat and instant messaging differs from other technologies such as e-mail due to the perceived synchronicity of the communications by the users –chat happens in real-time. Some systems permit messages to be sent to people not currently 'logged on' (offline messages), thus removing some of the differences between IM and e-mail (often done by sending the message to the associated e-mail account).
IM allows effective and efficient communication, allowing immediate receipt of acknowledgment or reply. In many cases instant messaging includes additional features which can make it even more popular. For example, users can see each other by using webcams, or talk directly for free over the Internet using a microphone and headphones or loudspeakers. Many client programs allow file transfers as well, although they are typically limited in the permissible file-size.
It is typically possible to save a text conversation for later reference. Instant messages are often logged in a local message history, making it similar to the persistent nature of e-mails.
