Asynchronous Differential TDOA for Sensor Self-Localization

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
Most methods for sensor self-localization require either synchronization or round trip communications among the networked sensors. A differential time-difference-of-arrival (dTDOA) method is proposed in this paper that does not require such time synchronization nor round trip communications, thus greatly reduces demand on sensor communications ...

Sensor System with Differential Arrangement of Temperature MOS Sensor

2005 IEEE International Conference on Industrial Technology, 2006
In this article, an arrangement of a temperature sensor system is presented. The system utilizes temperature dependence of the current through the channel of MOS structure. Differential arrangement of the temperature sensor is designed. The arrangement allows measurement of temperature gradient.

Acceleration sensor with differential capacitance

The Journal of the Acoustical Society of America, 1992
In an acceleration sensor, in particular for automobiles, at least two electrodes which are surrounded by a dielectric are arranged, substantially parallel to each other, in a housing and immersed over part of their length in an electrically conductive liquid. Flip-flops output pulses having durations based on capacitance of the sensor.

A differential fibre- optic sensor for the monitoring of ultrasound

Transactions of the Institute of Measurement and Control, 1998
Knife-edge and differential optical beam deflection (OBD) techniques are capable of non-contact broadband measurement of laser-generated ultrasound. We describe a fibre-optic sensor based on both knife-edge and differential schemes, which has an angular deflection sensitivity of ~ 1 μrad.

A differential active pixel sensor

SPIE Proceedings, 2004
A differential active pixel sensor in present day CMOS technologies is described. The primary goal of the architecture is to reduce visible noise artifacts in the output image. Artifacts caused by gain mismatches among pixel elements, kTC noise, fixed-pattern noise due to reset mismatches, and corrupted pixels are considered.

Urease sensors based on differential antimony electrodes

Biosensors, 1986
Urea-sensitive sensors, based on immobilized urease and the differential antimony electrode, have been constructed. The calibration curve of the sensor is linear up to 1.6-2.0 mmol litre-1 in the stationary or kinetic mode of operation. The sensors retain 50% of their sensitivity for 16-17 days.

Contamination insensitive differential capacitive pressure sensors

Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat. No.00CH36308), 2000
In this paper, a contamination-insensitive differential capacitive pressure sensor with a sealed gap is presented. This device is made of three polysilicon layers including a stationary middle plate and the top and bottom plates that are rigidly coupled together by a series of posts hence deflecting in tandem by a change in differential or gauge ...

DIFFERENTIAL PRESSURE SENSOR

2002
The invention relates to a differential pressure sensor having a low hysteresis volume. Said sensor comprises a sensor element (1), two pressure measuring chambers (21, 31) which lie adjacent to the sensor element, two pressure receiving chambers (22, 32) which are closed by separating membranes (21, 31), and two overload chambers (23, 33) which are ...
