摘要： The values of the parameters of a large-signal S-parameter model of a device-under-test are determined by using a frequency-offset probe-tone method and by measuring and processing the spectral components of the scattered voltage waves with frequencies equal to the fundamental frequency, the fundamental frequency plus the said frequency offset and the fundamental frequency minus the said frequency offset. The resulting large-signal S-parameter model accurately and completely describes the amplifier nonlinear behavior with a large one-tone excitation at the input in a near matched environment at the output.

摘要： A system and method for detecting a defect in a transistor array includes applying a test signal to the array, monitoring pixel voltage along a gate line of the array, and detecting a defect associated with the gate line based on a variation in the pixel voltage during the monitoring step. The defect may be a short between the gate line and a common line of the array. The gate line and common line may be associated with a same pixel element or different pixel elements. The system and method also detect a precise location of the defect based on a rate of change in the variation of the pixel voltage along the gate line. The rate of change may be measured in any one of a variety of ways. For example, the rate of change may be measured as a sudden increase or increase of the pixel voltage or as a change in slope of a pixel voltage profile. Alternatively, the location of the defect may be detected as corresponding to a minimum or maximum value in a pixel voltage profile. The transistor array may be a TFT array or another circuit which includes an array of transistors.

摘要： An apparatus for measuring the electrical characteristic of a chip-shaped electronic component having first and second external terminal electrodes at first and second opposing ends thereof includes a holder that holds an electronic component with the first and second external terminal electrodes pointing toward first and second open ends of a receiving cavity. The holder is provided with a shield layer extending between first and second measuring terminals, and the shield layer is electrically connected to a measurement reference potential. The shield layer reduces the stray parasitic capacitance adjacent to the electronic component, and reduces measurement errors resulting from size variations of the electronic component.

摘要： A position and electromagnetic field sensor is provided. The sensor relies upon an oscillator such as a Robinson marginal oscillator to generate an rf or microwave electromagnetic field. As an inhomogeneously shaped object, such as a metallic toothed wheel, for example, moves through the resultant field, the field experiences a change in electric or magnetic susceptibility. This in turn causes energy losses in the oscillator the magnitude of which can be output as a d.c. signal related thereto. To detect non-moving objects which nevertheless generate an electromagnetic field or have attached to them a source thereof, the sensor also includes a giant or colossal magnetoresistive structure located adjacent the oscillator coil, the structure having an imaginary magnetic susceptibility which is strongly dependent upon the magnitude and direction of the field generated by or at the object to be sensed.

摘要： A moisture meter (1) has a capacitive sensing circuit (11-16) feeding into a digital control circuit having a microcontroller (17). Input buttons (20, 22, 23) allow a user to select a material being surveyed. They also allow the user to instruct the meter (1) to hold a particular reading. This allows it to be more conveniently read. The output of the digital control circuit is fed via an ADC (18) to a moving coil meter (4). This provides an easy-to-read display in which trends as the meter (1) is moved across a surface are easy to track.

摘要： An inductive proximity sensor has an oscillatory circuit (L, C, Rp), an electric energy source (11) coupled to the oscillatory circuit for compensating losses in the circuit, and a filter (15) for compensating signal changes encountered in the oscillatory circuit. The input of the filter is coupled to the oscillatory circuit and its output is coupled and sending output signals to the energy source. The energy source changes the energy or current supplied to the oscillatory circuit as a function of the output signals from the filter to thereby actively compensate for signal changes encountered in the oscillatory circuit.

摘要： A system for modifying the power up and diagnostic procedure of systems such that the system voltage is lowered to a predetermined voltage level that has been shown to detect delay faults. The system conducts the normal procedure of power up/diagnostic routines at the described VLV condition and then logs failures to this VLV condition. Upon completion of the VLV power up, the system is shut down normally and then subsequently powered up again at the normal voltage conditions. Discrepancies between the VLV power up/diagnostics are noted in the system log and communicated appropriately.
