Over the past few years we've covered several devices for the blind and visually impaired, ranging from wrist-mounted sonars to guide vests with helmet-mounted cameras. As . Personnel Training Publications: Ultrasonic Testing (UT), Classroom Training Book, Second Edition Contains new chapters on phased array, time of flight diffraction, and guided wave method. Follows the body of knowledge outlined in CP ().
The powered ultrasonic transducer is a plate radiator type presented in another chapter of this book (Gallego-Juárez et al., n.d.). The radiator is a rectangular plate designed to vibrate in one of its simpler flexural vibration modes (two nodal lines parallel to the longer side of the plate) to avoid as much as possible great differences in Cited by: A.

Scan-Read Devices Welcome to the section of our site devoted to scanners and readers for those with low vision or the blind. This section features Braille Displays, Simon Stand Alone Reading Machine, Portset Reader, Libra Reading Machine, PC Based Readers, Scan-A-Can for Windows Deluxe, Visability (Low Vision Scan and Read System). The GuideCane — A Computerized Travel Aid for the Active Guidance of Blind Pedestrians by aid for the blind is the white cane. It is used to detect obstacles on the ground, uneven surfaces, equipped with ultrasonic sensors and a computer. A prototype of this.

An Ultrasonic Navigation System for Blind People. The aim of this paper is to investigate the development of a navigation aid for blind and visually impaired people. Ultrasonic navigation. Ultrasonic Sight is an electronic device for mobility, sociality and welfare of blind and visually impaired people.
The idea of developing such a device arises An ultrasonic aid for the blind book several aspects concerning the device market and from the everyday blind and visually impaired people problems.
Using an ultrasonic emission similar to the cone of light of a flashlight, Ray can recognize obstacles up to a distance of feet ( meters) away and announce them to the user via an audible or vibrating signal. IMPORTANT NOTE: Ray is intended as a complement to.
The UltraCane - an award winning primary mobility aid. Developing safer alternatives sincethe UltraCane is a primary electronic mobility aid for use by people who are blind or visually impaired and is THE ONLY electronic mobility aid that utilises state of the art "narrow beam technology", allowing the user to safely avoid obstacles and navigate around them, both in the user's forward.
The current study deals with the development of an ultrasonic based cane for the navigation of the blind persons. The developed cane is able to detect both aerial and ground obstacles and potholes.
Sensory 6*: Ultrasonic Mobility Aid for the Blind. The objective of this paper is to introduce the Sensory 6, a new hands-free ultrasonic travel aid (ETA) for the blind and to describe the process which culminated in its development.
The main function of any ultrasonic ETA is to extend the user’s perception to include the environment beyond. The Miniguide mobility aid The Miniguide uses ultrasonic echo-location to detect objects.
The aid vibrates to indicate the distance to objects - the faster the vibration rate the nearer the object. There is also an earphone socket which can be used to provide sound feedback. A headphone jack can be used to provide sound feedback. The Miniguide supplements the information provided by a guide dog or cane—an interesting alternative for visually impaired or blind users.
The Miniguide is not to be used as a primary aid. Dimensions: Size: 3" long, " wide by " thick; Weight in ounces: (66 grams) with battery. Conceptualised a portable eBook reader which allows the blind to feel the Braille characters with a blind stick which can detect obstacles.
Drishti - Low Cost Blind E-book Reader And Stick by Drishti. Blind stick is an innovative stick designed for visually disabled people for improved navigation. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology.
The blind stick is integrated with ultrasonic sensor. Abstract -Blind people need some aid to feel safe while moving. Smart stick comes as a proposed solution to improve the mobility of both blind and visually impaired people.
Stick solution use different technologies like ultrasonic, infrared and laser. The software concept together of the structure of the respective application has.
Another reason why ultrasonic is popular is that the technology is relatively inexpensive, and also ultrasound emitters and detectors are small enough to be carried without the need for complex circuitry.
The project is based on a theoretical model and a system concept to provide a smart electronic aid for blind people. Ultrasonic Instruments and Devices provides a rigorous introduction to the technology and techniques of modern ultrasonic instrumentation.
A chapter is devoted to each major engineering area, and each chapter is written by one or more world-class experts in the particular area covered by the chapter. Using an ultrasonic emission similar to the cone of light of a flashlight, Ray can recognize obstacles up to a distance of feet ( meters) away and announce them to the user via an audible or vibrating signal.
IMPORTANT NOTE: Ray is intended as a complement to Brand: Caretec. information by the ultrasonic sensors which will be aid for blind pedestrian. The authors expect that the project will be very useful for blind pedestrian where Ultrasonic sensors are used to detect the object or obstacle in path and navigate the blind person by the use of audio Size: KB.

A method for processing a reflected echo signal which is received from an object and supplied to an ultrasonic binaural sensory aid comprising the step of stretching said reflected signal in time axis, and the step of converting the stretched signal into a signal of audible frequency, and a blind aid which works by the above mentioned by: Abstract Abstract There is approximately million people in the world are blind in according to World Health Organization.
Majority of them are using a conventional white cane to aid in navigation. The limitation in white cane is that the information’s are gained by. Electronic Travel Aids for Blind Guidance An Industry Landscape Study IND ENG Project Report, Fall Abstract Electronic travel aids should replace the traditional ones to assist the million vision impaired population globally.
