Abstract: M periods of the test signal and of the reference signal are received. The periods of the test signal and of the reference signal are in each case Tsig long. The test signal is sampled with N sampled values at a sampling frequency fs=1/Ts. Also, N*Ts=M*Tsig, where N>M. The sampled values are numbered progressively by n, for which 0?n ?N?1. The sampled values have a defined relative phase shift with respect to the reference signal. The phase shift T? is calculated by ? i = 0 M - 1 ? ? Idx ? ( i ) + K , K being a constant and Idx(i) corresponding to the number n which is either the first sampled value after a test signal zero crossing during the reference signal's ith period or the last sampled value before a test signal zero crossing during the reference signal's ith period. Either only rising or only falling zero crossings are taken into account.

Abstract: An apparatus and method for detection of airborne contaminants and prevention of influx of the contaminants into an enclosed space, such as a vehicle cabin. A first sensor array samples exterior air prior to influx of the exterior air into the enclosed space. The first sensor array generates data uniquely corresponding to each contaminant. Data corresponding to predetermined contaminants is stored in computer memory. A user may also cause data corresponding to a contaminant selected by the user to be stored in the computer memory. Upon identification of a contaminant, an actuator is operative to control a position of a valve to prevent influx of the exterior air into the enclosed space.

Abstract: Configuration of an ultrasonic inspection system is facilitated using an ultrasound response predicted by a simulation tool. In one embodiment, estimated material properties of an object to be inspected are input to the simulation tool. Also input to the simulation tool is at least one estimated property of an ultrasonic transducer of the ultrasonic inspection. The simulation tool predicts the response of the object to ultrasound from the ultrasonic transducer. This response is dependent upon the estimated material properties of the object to be inspected and the at least one estimated property of the ultrasonic transducer. The ultrasonic inspection system is then configured dependent upon a feature of the predicted response. The system may be configured, for example, by setting the position of a time gate, selecting an appropriate ultrasonic transducer, selecting the position of the transducer to achieve good focus, or selecting parameters for signal processing.

Abstract: A test system and computer program for measuring threshold voltage variation using a device array provides accurate threshold voltage distribution values for process verification and improvement. The test system and computer program control a characterization array circuit that imposes a fixed drain-source voltage and a constant channel current at individual devices within the array. Another circuit senses the source voltage of the individual device within the array. The statistical distribution of the threshold voltage is determined directly from the source voltage distribution by offsetting each source voltage by a value determined by completely characterizing one or more devices within the array. The resulting methodology avoids the necessity of otherwise characterizing each device within the array, thus reducing measurement time dramatically.

Abstract: In the method for estimating battery residual capacity of the present invention, the voltage measurement values are obtained (step S2). And once it is finished, using the initial values of the coefficients set at the step S3 as starting, the optimization is progressed with renewing each value of the coefficients on the following iterating calculations (step S4). Once the optimum value of each coefficient in the approximation is determined at the step S4, the stable open circuit voltage is calculated by the optimized reciprocal function using thereof at the step S5. And then based thereon, the battery residual capacity is calculated by the predetermined conversion method (step S6).

Abstract: A design structure for an apparatus for utilizing a single set of one or more thermal sensors, e.g., thermal diodes, provided on the integrated circuit device, chip, etc., to control the operation of the integrated circuit device, associated cooling system, and high-frequency PLLs, is provided. By utilizing a single set of thermal sensors to provide multiple functions, e.g., controlling the operation of the integrated circuit device, the cooling system, and the PLLs, silicon real-estate usage is reduced through combining circuitry functionality. Moreover, the integrated circuit device yield is improved by reducing circuitry complexity and increasing PLL robustness to temperature. Furthermore, the PLL circuitry operating range is improved by compensating for temperature.

Abstract: A current Ibe and a voltage Vbe before a large current discharge in a secondary battery are stored in a memory. Plural voltage-current pairs are detected and stored in the memory during the large current discharge. Next, a regression curve (or a regression line) is obtained based on the plural voltage-current pairs stored in the memory using a well-known method. A discharge current Ip which exceeds a current-sensor detectable range is input in the regression curve to obtain a voltage Vp. A maximum discharge coordinate is set using the discharge current Ip and the voltage Vp. An internal resistance Rin of the secondary battery is calculated based on an inclination of a line that connects the coordinates (Ibe, Vbe) and (Ip, Vp).

Abstract: It is possible to detect a reception signal at a high speed. A wave detection device includes: a first signal output unit for outputting a first signal s[n] which is a sum of a digital input signal subjected to A/D conversion and an output from a feedback signal output section; a second signal output unit for outputting a second signal s[n?1] which is the first signal s[n] delayed by one sampling timing; and a feedback signal output section for subjecting the second signal s[n?1] to a predetermined calculation. When n=N?1, a frequency region conversion section reads out the first signal s[N?1] and the second signal s[N?2] from registers and subjects them to a predetermined calculation, thereby obtaining the input signal subjected to DFT. Since the wave detection device has a simple configuration, it is possible to rapidly detect the reception signal which is an input signal of the wave detection device.
