Abstract: A system is disclosed for manipulating buses and signals on a display window of a graphical user interface of a logic analyzer. Each signal is associated on the display with representations of its sampled data, which may be in the form of lists or of waveforms. The system enables a user to graphically associate the buses and signals. Also, the buses and signals may be visually associated on the display window with user-specified trigger-conditions. The User may graphically associate the signals into buses by selecting the signals then grouping them by selecting a group command. Responsive to this grouping, the system may generate a bus representing the grouped signals. The bus may be graphically associated with the grouped signal-name elements, such as, for example, by a hierarchical structure. The system, responsive to the grouping by the user of the signals into buses, generates bus-data elements representing signal data associated with the grouped signals.

Abstract: The present invention is directed to a photoconductive switch module. The photoconductive switch module comprises a first substrate having light-emitting elements, and a second substrate having photoconductive switch elements, whose number is equal to that of the light-emitting elements. The light-emitting elements face the photoconductive switch elements, so that the photoconductive switch elements are turned on/off in accordance with lighting/extinction of the light-emitting elements. The photoconductive switch module further comprises a third substrate arranged between the first substrate and the second substrate. The third substrate has through holes, whose number is equal to that of the light-emitting elements. Each through hole is positioned between a light-emitting element and a photoconductive switch element facing each other. Drive light emitted from each light-emitting element travels to the photoconductive switch element via the through hole.

Abstract: A comparator-type sense amplifier compares a constant voltage that was read out of a FeRAM cell to a sequence of reference voltage levels. A multiple-comparison operation includes (a) reading out data to a bit line, (b) applying a first/next reference voltage, (c) comparing the bit line voltage to the applied reference voltage, and (d) repeating steps (b) and (c) one or more times. The multiple comparison operation can be used to characterize operation of an FeRAM cell, predict or detect an FeRAM cell that may introduce a bit error, or to read a multi-bit value from an FeRAM cell.

Abstract: A high-precision high-linearity digital-to-analog converter (DAC) and a method for converting a digital input signal having N bits to a substantially equivalent analog current output signal is presented. The DAC segments the digital input signal bits into groups separate processing. The invention includes a first current-steering digital-to-analog converter configured to receive a first group of i input signal bits and a first reference current to produce a first current signal. A second current-steering digital-to-analog converter is configured to receive a second group of j input signal bits and the first reference current to produce an intermediate current signal. The intermediate current signal is scaled down by a factor of 2j to produce a second current signal. A summing circuit sums at least the first and second current signals to produce an analog current signal representative of the digital input signal value.

Abstract: A series of logic clouds is used to distribute and propagate signals traveling a relatively long distance across a data logic circuit fabric. One or more long distance signals originate from an initial logic cloud that may be located on a source data block and pass through a series of logic clouds that may be located on an intermediate data block before passing through a destination logic cloud located on a destination data block. Each logic cloud reads both stabilized logic signals and long distance signals and employs a NAND gate connected with an inverter to perform not only logical operations but also to act as a repeater between the logic clouds. The stabilized logic signals may represent signals that originate from other sources along a given data path.

Abstract: The present invention relates to a microdevice having a valve structure that contains low or no dead volume. The microdevice comprises a substrate and a cover plate each having a substantially planar contact surface and each contact surface having a fluid-transporting feature associated therewith. The substrate contact surface is positioned in slidable and fluid-tight contact with the cover plate contact surface to allow for controllable alignment between the fluid-transporting features. As a result, fluid communication is provided therebetween through a small area. Where the cover plate fluid-transporting feature comprises a conduit, the conduit may have a substantially constant cross-sectional area. The controllable alignment between the fluid-transporting features may form an alignment-dependent variable-length flow path.

The second comparator stage receives the analog signal, as well as the set of reference voltages output from the voltage reference stage, and outputs a thermometer code in response to comparisons of the analog signal to the reference voltages. The switching stage receives the control signal, and in response thereto, variously couples inputs of the encoder to: bits of the thermometer code output from the second comparator stage, a first potential, or a second potential. Methods for converting analog signals to digital signals are also disclosed.
