New surface acoustic wave gas sensor of the mass-sensitive type sensitive to the thermal properties of gases
Tập 1 - Trang 372-375 vol.1
The basic principles of a new surface acoustic wave (SAW) gas sensor are
described. Being essentially a sensor of the mass-sensitive type, the proposed
device possesses certain features of the thermometric SAW sensors and is not
only sensitive to the vapors of volatile substances, but capable of detecting
gases by their thermal properties as well. This principles consists of making a
certain delay...

The wavelength sensor using optical directional coupler
Tập 1 - Trang 83-85 vol.1
This paper proposes a wavelength sensor based on an optical directional coupler.
The finite-difference time-domain (FDTD) method is used to calculate of the
light intensity propagating thorough the structure, and to find the appropriate
dimensions of the structure. The device with the width and thickness of 0.4 /spl
mu/m/spl times/0.6 /spl mu/m, which corresponds to the coupling length of 40
/spl ...

Electronic interface modules for solid-state chemical sensors
Tập 1 - Trang 344-349 vol.1
Plug and play modules for interfacing three common types of solid-state chemical
sensors are presented The self-contained (integrated circuit) modules detect a
baseline signal from a sensor and auto-zero the signal to compensate for
baseline variations, both immediately after fabrication and periodically during
the lifetime of the sensor The signal compensation technique is based on the
governing ...

GaPO/sub 4/ crystals for sensor applications
Tập 1 - Trang 589-593 vol.1
The piezoelectric crystal material gallium (ortho) phosphate GaPO/sub 4/ can be
considered to be the "high tech brother of quartz". The high thermal stability
up to 970/spl deg/C and its high sensitivity make GaPO/sub 4/ a very attractive
choice for a wide range of high temperature applications. Furthermore it shows
no pyroelectricity, no outgassing and a high electric resistivity to guarantee
hig...

Non-idealities of temperature sensors using substrate pnp transistors
Tập 2 - Trang 1018-1023 vol.2
This paper describes the nonidealities of temperature sensors based on substrate
pnp transistors and shows how their influence can be minimized The effects of
series resistance, current-gain variation, high-level injection and the Early
effect on the accuracy of the PTAT voltage are discussed. The results of
measurements made on substrate pnp transistors in a standard 0.5 /spl mu/m CMOS
process ar...

Characteristic of thin-film NTC thermal sensors
Tập 1 - Trang 56-61 vol.1
The characteristics of thin-film negative temperature coefficient of resistance
(NTC) thermal sensors fabricated by micromachining technology were studied as a
function of the thickness of the membrane. The overall structure of the thermal
sensor has the form of Au/Ti/NTC/SiO/sub x//(100)Si. An NTC film of Mn/sub
1.5/CoNi/sub 0.5/O/sub 4/ with 0.5 /spl mu/m thickness was deposited on the
SiO/sub x...

Frequency interference between two quartz crystal microbalances
Tập 2 - Trang 1148-1153 vol.2
In this paper, the frequency interference between two quartz crystal
microbalances (QCMs) is investigated. Based on Mindlin's theory, the influence
of design parameters on the frequency behavior of the QCM structure is studied.

Common design techniques for quartz rate sensors for both automotive and aerospace/defense market applications
Tập 2 - Trang 1597-1602 vol.2
In the early 1990s, Systron Donner Inertial Division (SDID), a subsidiary of BEI
Technologies, Inc., possessed a new solid-state rate gyroscope technology that
had not yet matured or captured a significant market share. Even though some
success had been achieved in defense missile applications, a strategy was
clearly needed to further develop the technology and lay the foundation for
future growth...

Esbus - a sensor bus based on the SPI serial interface
Tập 2 - Trang 1516-1519 vol.2
A local sensor bus for transmitting data from several digital smart sensors to
an Internet interface was tested. The master/slave type bus is based on the
three-wire SPI (serial peripheral interface) bus, which is built into most
microcontrollers. At the sensor end, after A/D conversion of the analog sensor
signals and further processing of the digitized data, the data is formatted into
standard 8...
