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 کاملELECTIVE VERSUS ULTRASOUND –INDICATED CERVICAL CERCLAGE IN WOMEN AT RISK FOR CERVICAL INCOMPETENCE
ABSTRACT Background: To compare pregnancy outcomes in women at risk for cervical incompetence after elective versus ultrasound- indicated cerclage. Methods: In a prospective randomized tlial, singleton pregnancies with at least one previous spontaneous midtrimester loss or early preterm delivery (between 15 and 32 weeks' gestation) who met clinical crite1ia for the diagnosis of cervical incomp...
متن کاملFocused Ultrasound for Tactile Feeling Display
We studied on the feasibility of focused ultrasound for tactile feeling display. Our experiments showed that focused ultrasound at 1 MHz and 5 MHz effected our somatic sensation both by its radiation pressure and by direct stimulation to the nerve structures. The radiation pressure force generated by our apparatus was 0.23 gf/cm per 1-watt power consumption and evoked tactile feeling stably, wh...
متن کاملCharacterization of Precipitates with the Atom Probe
The parameters that can be measured from atom probe random area analyses of small spherical precipitates and platelets have been examined with a combination of simulation and geometrical models. The results indicate that the probe aperture should be less than 50% of the diameter of the precipitate in order to reliable measure the true composition in a significant proportion of precipiates.
متن کاملEvaluation and Characterization of Free and Immobilized Acethylcholinesterase with Fluorescent Probe, Differential Scanning Calorimetry and Docking
Acetylcholinesterase (AChE) enzyme which catalyses the hydrolysis of choline esters, such as acetylcholine, is very important in nerve function. Previous structural studies showed the possible amyloid fibril formation on the AChE. Therefore it is important to understand interaction of ligands to prevent the formation of amyloid fibrils. The purpose of the present study was to char...
