Micro-Sonde Well Logging System

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1466850

The micro-sonde well logging system utilizes miniaturized data logging devices, which are released at the bottom of a well and record downhole parameters whilst being transported by fluid flow to surface. The μSonde capsules are designed to be small enough to pass restrictions without obstructing th...

Thermal Management System for Particle Sensors Design, Performance and Verification

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+946673

This paper presents the thermal performance of a proposed thermal management device (patented in 2009) intended for a thermophoresis-based soot sensor. The performance was studied for temperatures ranging from 50 to 400 °C and for exhaust speeds up to 10 m/s. It also presents the design and basic co...

Smart Textiles - Safety for Workers in Cold Climate

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S21506

The cold and harsh climate in the High North represents a threat to safety and work performance. Clothing equipped with sensors that can monitor the workers and give an “early warning” before working condition approaches dangerous levels. In this project a demonstrator consisting of a working jacket...

A mixed-signal BiCMOS Front-End Signal Processor for High-Temperature Applications

http://www.sintef.no/publikasjoner/publikasjon/?pubid=SINTEF+S303

A mixed-signal ASIC that implements an ultrasound front-end receiver in a 0.6 m BiCMOS HotASIC technology that features metal/metal capacitors and poly1/poly2 resistors is described. The ASIC includes a low-noise amplifier (LNA), a programmable gain amplifier (PGA), an output differential amplifier ...
