RFID Reader Sensor [EE]

Ali AlMatrouk, Alfredo Bermudez, Jeff Kakinami

The development of an RFID (Radio Frequency Identification) sensor consists of an RFID reader that can interface with the NXT. This provides LEGO Mindstorms NXT users the ability to create robots that can sense objects in their environment using radio frequencies. An RFID Sensor interfaced with the NXT will be capable of reading information from RFID tags and processing the information into the NXT. The output of an RFID reader will be interfaced to the input of the NXT central processing unit. This will enable the NXT to perform numerous other applications, such as taking an inventory of all the tags read within an area or going into search mode with its other sensors once the RFID reader picks up a strong signal from the RFID tag. Since the NXT can serve as a model for larger autonomous robots, the RFID sensor will benefit those who wish to simulate potential real-world RFID projects in a time when RFD technology is quickly expanding.

Water Purification [ME]

Cheryn Engebrecht, Ian Metzger, Matthew Petrucci, Colin Porterfield

According to an article published by the Red Cross in March 2005, over 1.1 billion people lack access to safe drinking water. As a result, over 2.2 million people die from unsafe drinking water every year. The need for simple, efficient, and inexpensive water purification has become increasingly urgent. The goal of the COOL Water Purification Project is to make potable water using electro-mechanical power to boil contaminated water and extract clean vapor. This is accomplished by converting mechanical power into electrical power through a generator. This electric current runs through the contaminated water transferring heat, causing it to boil. The water vapor created then condenses through a concentric tube heat exchanger and the result is potable water. The amount of power transmitted to the water will be efficient and all components of the device will be low cost and simple to construct/maintain.
