''We wanted to dosomething that would help people and make our campus more accessible. '' During the spring term, Yelamarthi and five senior engineering studentstested the cane, which is equipped with Radio Frequency Identificationtechnology, similar to what retailers put on products to keep them frombeing stolen. The Smart Cane contains an ultrasonic sensor that is paired with aminiaturenavigational system inside a messenger style bag worn across the shoulder. For the test, the students installed identification tags between twobuildings on the campus in Mount Pleasant, Mich. A speaker located on thebag strap gave audio alerts when the system detected an obstacle and toldthe user which direction to move. Students wearing glasses that simulate visual impairment tested the cane. The students also created a vibrating glove to assist those who are bothvisually and hearing impaired. Yelamarthi said it's one of the first outdoor applications of RFID and saidhe plans for students in upcoming classes to further refine the systemwhilehe seeks grants to speed the research. The next step probably involves using the system in a wider area. Down theline, Yelamarthi wants to work toward integrating the Smart Cane's datawithGPS.

security for the home

This one part panel is easier to install but has one weakness. An intruder entering through the door can tear it off the wall before the panel finishes notifying the monitoring service. With a two part panel, the circuit board keeps working even if the keypad is disconnected. With either type of panel, you’ll need a special phone jack called an “RJ31X” to connect the panel to your phone lines. You won’t find professional quality alarm equipment at a local electronics retailer. Instead, fire up your computer and search for “security alarms” or “security systems. ” Look for suppliers that carry multiple brands and models so you don’t get locked into home security equipment that’s not right for you. In addition to good selection, look for a supplier that offers free system programming and technical support. Make sure the supplier doesn’t require a high cost, long term monitoring contract. Before you place an order, call the supplier and discuss your plan. The staff will help you develop a materials list and program the alarm panel appropriately.
