Abstract: An excitation signal is produced on a plate of an unknown capacitor and on a plate of a known capacitor. The excitation signal is amplified over time to produce a first output signal, with gain that is proportional to capacitance of the unknown capacitor. The excitation signal is also amplified over time to produce a second output signal, with gain that is proportional to capacitance of the known capacitor. Capacitance of the unknown capacitor is computed using a mathematical function of the first and second output signals and the capacitance of the known capacitor, while being insensitive to amplitude of the excitation signal. Other embodiments are also described and claimed.

Abstract: The accuracy of reading characteristics or data of pixels or memory cells in a matrix device is increased. An electronic device includes a plurality of drive lines, a sense line intersecting the drive lines, a plurality of element devices provided at intersections thereof, a detecting circuit, a decoder, and a driver. The detecting circuit can detect a first physical quantity of the sense line and transmit a digital signal obtained by digitizing the first physical quantity to the decoder. Each of the element devices can change the first physical quantity of the sense line in accordance with a signal of the corresponding drive line. The driver can transmit coded signals based on a Hadamard matrix to the decoder and the drive lines. The decoder can perform arithmetic processing with use of the coded signals and the digital signal and calculate values based on second physical quantities of the element devices.

Abstract: A novel method for real-time small-signal stability analysis for power electronic-based components in a power system. The method may be used to monitor a power system in real-time by perturbing the source side of an electronic-based component of the power system of about 0.5 to 1 percent of a nominal current of the power system at the source side, and perturbing the load side of the power electronic-based component by varying the voltage at the load side using a series voltage injection. Time-domain results of the simultaneous perturbations may be transferred to frequency-domain results and the stability of the power system may be monitored by obtaining a Nyquist contour and employing Generalized Nyquist Criterion or unit circle criterion.

Abstract: An antenna checking circuit includes an antenna-connection-input terminal, a check-request-input terminal, a check-result-output terminal, a switching element having a control end connected to the check-request-input terminal, an input end connected to the antenna-connection-input terminal, and an output end connected to the check-result-output terminal, and a first resistance connected between the check-request-input terminal and the check-result-output terminal. A DC impedance of an antenna between a power supplying point and a ground point is 0Ω, and when a high-level check-request signal is applied to the check-request-input terminal, in a case where the antenna is connected to an antenna-connection terminal, the switching element turns on, and in a case where the antenna is not connected to the antenna-connection terminal, the switching element turns off. Check-result signals that are output to the check-result-output terminal in these cases are different from each other.
