burglar alarms system
Also if any home security wiring, telephone wires or low voltage wiring is ever present in the ductwork, the physical nature of the contact cleaning method in air duct cleaning will increase the chances in breaking such wires, whereas air washing will not compromise such wires in any shape way or form. Most contact cleaning companies will recommend that you should have your air ducts cleaned out every
year or two, because they know they left enough debris in the ductwork to try to get at it again in a year or two. Well there you have it folks. Both common methods in air duct cleaning really do have advantages and disadvantages. I attempted to write this article as fair and balanced as I could using as many facts based on past experiences that I have experienced in performing over 10,000 residential and over 2000 commercial air duct cleanings using both methods of cleaning. Based on my past experiences the advantages and disadvantages in both methods of air duct cleaning that I wrote about are very much so true in my experiences. There are many different cleaning machines and tools out there, which means’ that the chore in selecting a thorough air duct cleaner, can be daunting. I must say that experienced technicians in performing an air duct cleaning service can go along way, especially when a company is committed in investing in the more expensive forms of machinery and specialized tools as Lucky Duct, LLC is. In fact our
least experienced technician that would show up to your home or office has 3000 + residential air duct cleanings and 850 commercial air duct cleanings performed. Lucky Duct, LLC strives to take better care of our people in pay and benefits than most other companies which is why we have been so fortunate in attracting some of the best tech’s out there. Cool machines and tools help, but experienced people can really make the difference in a project result as well.

alarms for seniors
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. 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.
