A gazing point distance detection system for accommodation assisting glasses
SENSORS, 2002 IEEE - Tập 2 - Trang 905-910 vol.2
T. Fujita, S. Sato, M. Idesawa
Proposes a gazing point distance detection system which is one of the important key issues in order to realize accommodation assisting glasses, automatic focusing glasses which can assist eye focusing for aged persons who suffer from presbyopia. The new system has a tunnel type light path device which consists of very narrow tunnels with the opening of a vertically long rectangle. The tunnels are ...... hiện toàn bộ

Sub-micron range thickness measurements using a novel scanning heterodyne optical interferometer
SENSORS, 2002 IEEE - Tập 2 - Trang 1080-1084 vol.2
N.A. Riza, M.A. Arain
Introduces a novel and highly accurate method of thickness measurement using a compact, high performance, scanning heterodyne optical interferometer. The instrument has the potential to measure thickness at an Angstrom resolution over a micron continuous thickness range. The instrument uses acousto-optic devices to implement rapid scanning for thickness measurements of the test medium. As the read...... hiện toàn bộ

Optical fiber sensor using tailored porous sol-gel fiber core
SENSORS, 2002 IEEE - Tập 1 - Trang 71-73 vol.1
S. Tao, C.B. Winstead, R. Jindal, J.P. Singh
Novel techniques for fabricating a porous sol-gel fiber, doping chemical reagent into the fiber, and constructing an optical fiber chemical sensor using the porous fiber as a transducer, have been invented. A moisture sensor employing a CoCl/sub 2/ doped porous sol-gel fiber as a transducer has been constructed as an example. The test result of the moisture sensor verified a conclusion from theore...... hiện toàn bộ

Thermally activated ageing of polysilicon
SENSORS, 2002 IEEE - Tập 1 - Trang 602-606 vol.1
M. Ehmann, F. Schubert, P. Ruther, O. Paul
Thermally induced resistance changes and long term stability of polysilicon resistors were characterized for temperatures up to 1400 K. For this purpose, a new test microstructure was developed which is based on a micro hotplate with a central polysilicon resistor as the material under test and two polysilicon heaters for temperature cycling of the membrane. This test system allows the separate me...... hiện toàn bộ

Implantable glucose sensor: progress and problems
SENSORS, 2002 IEEE - Tập 1 - Trang 270-273 vol.1
F. Moussy
Although the first implantable glucose sensors were developed a few decades ago, there is still no glucose sensor that can work reliably and for a long period of time after implantation. This loss of function in vivo is caused by events that affect the sensor itself (e.g. degradation, fouling...), as well as by changes in the tissue surrounding the sensor, caused by the implantation. Therefore, in...... hiện toàn bộ

Active structural error suppression in MEMS vibratory gyroscopes
SENSORS, 2002 IEEE - Tập 2 - Trang 1089-1094 vol.2
C.C. Painter, A.M. Shkel
Due to restrictive tolerancing, structural imperfections that reduce the performance of fabricated micro devices are typical. While feedback control is normally used to compensate for these imperfections, we show that this is insufficient for suppressing errors without interfering with device performance. The only alternatives are costly and time consuming post processing or the implementation of ...... hiện toàn bộ

A textile based capacitive pressure sensor
SENSORS, 2002 IEEE - Tập 2 - Trang 1625-1630 vol.2
M. Sergio, N. Manaresi, M. Tartagni, R. Guerrieri, R. Canegallo
This paper introduces an approach for decoding the pressure information exerted over a broad piece of fabric by means of capacitive sensing. The proposed sensor includes a distributed passive array of capacitors (i.e. an array where no active elements are involved), whose capacitance depends on the pressure exerted on the textile surface, and an electronic system that acquire and process the subse...... hiện toàn bộ
