摘要： Exemplary embodiments provide a self-powered wireless gas sensor system and a method for gas sensing using the system. The system can be used to detect and constantly track a presence of various gases including hydrogen, ozone and/or any hydrocarbon gas, and remotely transmit the sensing signal. The system can include a low power gas sensor that consumes less than about 30 nano-watts of power. As a result, the system can detect the presence of hydrogen at about 10 ppm. The sensor can also provide a fast response time of about 1-2 seconds. In various embodiments, the system can be physically small and packaged with all components assembled as a single compact unit.

The phase shifter comprises a first differential amplifier, having one first signal output end and comprising an inductor, a first transistor and a second transistor, wherein the inductor is connected to the emitters (sources) of the first and the second transistors; and a second differential amplifier, having one second signal output end and comprising a capacitor, a third transistor and a fourth transistor, wherein the capacitor is connected to the emitters (sources) of the third and the fourth transistors. Wherein the bases (gates) of the first and the fourth transistors are signal input ends, and the bases (gates) of the second and the third transistors are coupled together. Further, the phase shift between one signal input end and the first signal output end or the second signal output end is determined by the intrinsic resistors of the transistors, the inductor and the capacitor.

摘要： A non-contact detection technique of measuring both the frequency and the amplitude of periodic movement using a property of nonlinear phase modulation is provided. In one embodiment, the technique can utilize a 22-40 GHz radar sensor. Embodiments do not require calibration of signal amplitude for accurate measurement of movement amplitude. In addition, self-verification is possible. Furthermore, embodiments can provide measurements of frequency and amplitude using a very simple architecture. The method can be used to detect movements with amplitudes larger than 0.335 of the carrier wavelength for a fixed carrier frequency system and 0.214 of the minimum carrier wavelength for a frequency tunable system.

摘要： In accordance with one embodiment of the present intention, an adaptive feedback controller is configured to substantially reduce an error control signal defined by the difference between a command signal and the output signal of a controlled device. The adaptive controller comprises a step generator circuit configured to provide a control signal which is employed to vary the input signal received by the controlled device, The control signal is substantially in the shape of a ramp signal having a given slew rate. An adaptive slew rate computation circuit is coupled to the step generator so as to provide a slew rate compensation signal to the step generator to increase the slew rate of the control signal, when the controlled device is responding to a substantially fast varying input signal. The slew rate compensation circuit decreases the slew rate of the control signal, when the controlled device is responding to a slow varying input signal.
