Hand Gesture Recognition Using Ultrasonic Waves
This paper presents a new method for detecting and classifying a predefined set of hand gestures using a single transmitter and a single receiver utilizing a linearly frequency modulated ultrasonic signal. Gestures are identified based on estimated range and received signal strength (RSS) of reflected signal from the hand. Support Vector Machine (SVM) was used for gesture detection and classifi...
متن کاملAn Active Hand-held Instrument for Enhanced
This paper presents the first prototype of an active hand-held instrument to sense and compensate physiological tremor and other unwanted movement during vitreoretinal microsurgery. The instrument incorporates six inertial sensors (three accelerometers and three rate gyros) to detect motion of the handle. The movement of the instrument tip in three dimensions is then obtained using appropriate ...
متن کاملPreliminary study of a novel dental hand instrument for restorative procedures
Background. There is no clear consensus on operative hand instrumentation. In general, there is one hand instrument that completes one task. Consequently, numerous instruments are required for the placement, shaping and carving of a restoration. This reduces clinical efficiency, increases cost and may generate frustration. Methods. A novel dental hand instrument has been developed. The instrume...
متن کاملCutting ability of an ultrasonic retrograde cavity preparation instrument.
The aim of this study was to investigate the cutting ability of a working ultrasonic instrument designed for surgical endodontic use (Neosonic, Amadent Corp, Cherry Hill, NJ, USA). Three designs of tip, designated CT 1 to CT 3 were calibrated by measuring their displacement amplitudes in air using light microscopy over a range of power settings. Extracted teeth were sectioned longitudinally and...
متن کاملDesign and Development of Ultrasonic Testing Virtual Instrument
The optimization problem of ultrasonic testing instrument is studied in this paper. Using ultrasonic nondestructive testing technology to detect quality of products or parts, because the function of conventional ultrasonic testing instruments is custom-built and defined by manufacturers, it is very difficult to meet ever-changing testing requirements such as testing accuracy, testing efficiency...
