A 2-channel embedded infrared fiber-optic temperature sensor was fabricated using two identical silver halide optical fibers for accurate thermometry without complicated calibration processes. In this study, we measured the output voltages of signal and reference probes according to temperature variation over a temperature range from 25 to 225 °C. To decide the temperature of the water, the dif...

In this paper, we introduced a new fiber-optic temperature sensor with white light interferometric principle based on Fabry-Perot, which is capable of providing measurement for the temperature of greenhouse. The signal processing of system is that the optical signal wavelength is modulated in the Fabry-Perot cavity and is demodulated during the optical-electricity transform. Compared with a com...

This paper presents preliminary results regarding which features of pen-based gesture input are sensitive to cognitive stress when manipulated via changes in task difficulty. We conducted a laboratory study in which participants performed a vigilanceoriented continuous attention and visual search task. Responses to the search stimuli were entered via pen gestures (e.g., drawing a letter corresp...

This paper presents an ultra-low embedded power temperature sensor for passive RFID tags. The temperature sensor converts the temperature variation to a PTAT current, which is then transformed into a temperature-controlled frequency. A phase locked loop (PLL)-based sensor interface is employed to directly convert this temperature-controlled frequency into a corresponding digital output without ...
