ET DETROIT AP A cane equipped with the technology that retailers use totag merchandise could help blind people avoid obstacles. An engineering professor and five students at Central Michigan Universityhave created a ''Smart Cane'' to read electronic navigational tagsinstalledbetween buildings to aid the blind in reaching their destinations moreeasily. ''This project started as a way for me to teach students to see andunderstand the ways that engineering can be used for the greater good,''said Kumar Yelamarthi, the professor and project leader. ''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.For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered.Some systems store recorded video locally on an SD card or a solid state drive, while others offer cloud storage.Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to Lunaoverwrite video you may need later.Cloud Pandostorage makes it easy to store and access recorded video, but Alarm Panel it can cost hundreds of dollars per year depending on your subscription.Some Motion Activated Camerasystems offer both cloud storage and local storage, Cove Alarm Paneland some provide a dedicated storage drive that gives you DVR capabilities with time lapse recording, which makes it easy to find a video event that took place at a specific point in time.All of the systems we've Cove Glass break sensortested feature an app that lets you use your smartphone as yourYoutube command center to arm and disarm the system, create rules, add and delete components, and receive push notifications when alarms are triggered.Most apps also allow you to do things like view live and recorded Appvideo, lock and unlock doors, indeedchange thermostat settings, and silence alarms.Some apps will even use your phone's location services to glassdoorautomatically arm and disarm the system according to your physical location.The more expensive systems usually come with a wall mounted Linkpanel that acts as a communicationsLink hub, with a touch screen display that allows you to do everything the app does.The display lets youLink communicate with a professional monitoringLink service when an alarm is triggered and view video from any of the installed security cameras.While many systems use wireless components that are installed using double sided tape, some high end systems use components that require professional Linkinstallation. 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.
