The takeaway Frenzel goggles
OBJECTIVE To develop and evaluate new thin and light glasses for the examination of patients with nystagmus and to compare them with Frenzel goggles. METHODS First, we designed new examination glasses: a Fresnel-based device with a short focal length that is not as heavy or bulky as Frenzel goggles. Second, visual-fixation suppression of postrotatory nystagmus with Frenzel goggles and the Fre...
متن کاملA comparative study on the observation of spontaneous nystagmus with Frenzel glasses and an infrared CCD camera.
OBJECTIVES To compare the usefulness of a CCD camera with infrared illumination (IR-CCD camera) over Frenzel glasses (F Glasses) for the observation of spontaneous nystagmus, the incidence and direction of nystagmus, and the frequency, amplitude and slow phase of spontaneous nystagmus. METHODS One hundred vertiginous patients, fifty-three females and forty-seven males participated in this stu...
متن کاملMinimum Detectable Air Velocity by Thermal Flow Sensors
Miniaturized thermal flow sensors have opened the doors for a large variety of new applications due to their small size, high sensitivity and low power consumption. Theoretically, very small detection limits of air velocity of some micrometers per second are achievable. However, the superimposed free convection is the main obstacle which prevents reaching these expected limits. Furthermore, exp...
متن کاملExperimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator
In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind. The current study aims at developing a micro-position control system ...
متن کاملCFD Study on Hydrogen-Air Premixed Combustion in a Micro Scale Chamber
This paper reports a CFD modeling study to investigate the hydrogen-air mixture combustion in a micro scale chamber. Nine species with nineteen reversible reactions were considered in the premixed combustion model. The effect of operational and geometrical conditions including; combustor size, wall conductivity, reactant flow rates and hydrogen feed splitting on combustion stabilit...
