Airborne Ultrasound Tactile Display: Supplement
where w [W/m] and c [m/s] are the sound intensity and the sound velocity, respectively. N is the number of the transducers used to form the array. S [m] is the radiation area of a single transducer and Stot = NS. A common airborne ultrasound transducer, which is used for the measurement of the distance or the detection of objects, can emit about 0.041 W of ultrasound in normal use. Hence, if th...
متن کاملNon-contact Method for Producing Tactile Sensation Using Airborne Ultrasound
This paper describes a new tactile device which produces stress fields in 3D space. Combined with 3D stereoscopic displays, this device is expected to provide high-fidelity tactile feedback for the interaction with 3D visual objects. The principle is based on a non-linear phenomenon of ultrasound, acoustic radiation pressure. We fabricated a prototype device to confirm the feasibility as a tact...
متن کاملLinear Feedback Shift Register
A stream cipher is a symmetric cipher which operates with a time-varying transformation on individual plaintext digits. By contrast, block ciphers operate with a fixed transformation on large blocks of plaintext digits. More precisely, in a stream cipher a sequence of plaintext digits, m0m1 . . ., is encrypted into a sequence of ciphertext digits c0c1 . . . as follows: a pseudorandom sequence s...
متن کاملFeedback Shift Register Sequences
Feedback Shift Register (FSR) sequences have been successfully implemented in many communication systems for their randomness properties and ease of implementation. These include ranging and navigation systems, spread spectrum communication systems, CDMA mobile communication systems, and crypto systems such as streamciphers. This article gives a brief overview of FSR sequences, both linear and ...
متن کاملUltrasound Guided Hydrostatic Treatment of Meconium Ileus; another Indication for Ultrasound Based Approach to Bowel Obstruction
Dear Editor-in-Chief, The inspissated meconium pellets are a cause or effect of ileocolic obstructions. The present study aimed at explaining our experience of ultrasound-based approach for differentiation and treatment of the inspissated meconium pellets. This study was conducted at Mashhad University of Medical Sciences, Mashhad, Iran, from 2017-2020...
