A Vt independent voltage reference based on composite transistors operating in weak inversion

2011 Faible Tension Faible Consommation (FTFC), 2011
This paper describes a voltage reference circuit based on composite transistors and operating in weak inversion mode. The voltage reference was fixed in 100mV and the supply voltage can be as low as 0.8V. The weak inversion allows small current too leading the total power in the nW range. Simulation results points to a deviation (3σ and process corner)

The vibrotactile threshold (VT) at the fingertips of chain saw operators.

Central European journal of public health, 1997
The vibration sensitivity of the skin at the ten fingertips was tested with 72 chain saw operators examined due to VWF-disease and compared with controls. The vibrotactile perception threshold (frequency f = 125 Hz, load p = 1.3 N) proved to be 3 to 5 times as high for the exposed group compared to controls.

Dual threshold voltage adder for robust sub-Vt operation in 65nm technology

2013 IEEE SOI-3D-Subthreshold Microelectronics Technology Unified Conference (S3S), 2013
With the increased focus on power efficiency, there is a push towards lowering the supply voltage and operating the design in the sub-threshold regime. While this is good for lowering the active power, it makes certain circuits more susceptible to single-event effects due to poor Ioff/Ion ratio.

Unwanted operation of differential protection function in T60 relays due to failures in CT/VT modules

2018 International Conference on Computer, Control, Electrical, and Electronics Engineering (ICCCEEE), 2018
T60 relay is one of the new digital relays has been designed to meet the requirements of high sensitivity, reliability and high speed. This development led to notable simplification in transformer differential protection 87T function by reducing cost, cabling and auxiliary equipment.

VTS Operator Performance and Acceptance of a Short-Term Path Prediction Display in a Low Density Traffic Area

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2000
Vessel traffic management and control systems are employed to ensure the safety and efficiency of maritime traffic. In search for optimal support of Vessel Traffic Service (VTS) operators in performing their task, tools are developed continuously. This paper describes how the real users of the systems (VTS operators and managers) were involved in the ...

[The first 300 videothorascopic (VTS) and video-assisted (VATS) operations].

Rozhledy v chirurgii : mesicnik Ceskoslovenske chirurgicke spolecnosti, 1996
Videothoracoscopic and Videoassisted thoracic surgery makes diagnostic and therapeutic operation in the pleural cavity possible with minimal injury of the thoracic wall. The basic prerequisite is a free pleural cavity and selective pulmonary ventilation. VTS is a great asset in pulmonary biopsy, final treatment of a spontaneous pneumothorax, surgery of
