Abstract: A power-sensor module comprises a housing enclosing the power-sensor module. An input port of the housing brings an input signal into the housing. A power distributor, is within the housing. The power distributor has a first arm transmitting a first portion of the input signal and a second arm transmitting a second portion of the input signal. A first resistor is in the first arm and a second resistor in the second arm of the power distributor. An output port of the housing outputs from the housing the first portion of the input signal. A first thermal-based power detector detects heat generated by the second resistor caused by the second portion of the input signal and outputs a first power measurement signal based on the heat detected.

Abstract: Measurements for an eye diagram of a signal of interest are placed in a data structure that is examined to locate an eye opening of interest. The eye opening of interest is normalized into figure of merit units related to the operational voltage and timing requirements of the data receiver for that signal. The locations within the normalized eye opening may be taken as center locations for trial symmetric shapes that start out small and are enlarged until they first include locations not part of the normalized eye opening. The center of a largest such shape is mapped back into the units of the original eye diagram as optimum sampling parameters for data analysis equipment that uses the receiver to sample the signal once per unit interval to discover logical value. An alternative is to repeatedly remove the ‘outer layer’ of the normalized eye opening until only one location remains.

Abstract: A system and method for asynchronous triggering in a waveform generator comprising a DAC sample clock for generating DAC sample clock signal. The system includes a sequencer clock for generating a sequencer clock signal having a frequency of 1/N of the DAC sample clock. The system also includes an output data generator having I outputs to receive a waveform data stream of samples shifted into the data generator at the rate of the sequencer clock signal. An output multiplexer coupled receives samples from each of the I outputs of the output data generator and outputs the samples as a multiplexed data stream to the DAC. A triggering system receives an asynchronous trigger and splits the signal into an integer multiple M trigger inputs, each trigger input delayed by a DAC sample clock cycle. A shift controller determines a trigger position based on the trigger inputs and shifts a different waveform data stream into the data generator in accordance with the trigger position.

Abstract: The need for a Time Domain Integration line scan camera to change a workpiece's height in z to relocate an ROF (Range Of Focus) of fixed excursions about a fixed POLB (Plane Of Least Blur) is removed by making the location of the POLB movable, thus making the location of the associated ROF variable, while leaving the actual z height of the workpiece unchanged. This can be accomplished by ensuring that, for a desired new location of the POLB, the rate at which the physical ?ys transpire for the motion of the workpiece (which may be a PCA) matches the rate at which the optical ?ys are clocked for the TDI image sensor. That may be achieved by varying the value for physical ?y as function of the POLB's location in z regardless of Vscan, but while also adjusting Vscan if that is necessary or desirable to keep such things as sensor cell exposure levels, and contrast from moving away from their optimum values.

Abstract: A method useful in the analysis of glycosylated proteins, in which a mixture containing glycosylated proteins and unglycosylated proteins is contacted with a resin that includes a nucleophile bound to a solid support via a linker. The contacting is performed under conditions sufficient to result in removal of the glycosyl group from the glycosylated proteins and to concomitantly result in the deglycosylated proteins covalently bound to the solid support. The deglycosylated proteins bound to the solid support may be rinsed to remove proteins that are not covalently bound to the solid support. The deglycosylated proteins are released from the solid support and may be subjected to further purification and/or analysis.

Abstract: A tester module is used to perform an adjacent channel leakage ratio measurement. The tester module includes a translation block, a first filter, a re-sampler, a memory, a router, a second filter and a power detector. The translation block translates a received intermediate frequency signal to a baseband signal. The first filter compensates amplitude and phase of the baseband signal for any unflatness in host hardware used to capture the received intermediate frequency signal. The re-sampler decimates the compensated baseband signal. The memory stores the decimated compensated baseband signal. The router reroutes the stored decimated compensated baseband signal to the re-sampler. The re-sampler resamples the rerouted stored decimated compensated baseband signal to perform spectrum shifting. The second filter performs a low pass filtering operation on the resampled rerouted stored decimated compensated baseband signal.

Abstract: An apparatus having a proactive systemic scheduler connected with a network testing system. The scheduler receives a list of tests to be run on the network test system during a testing interval, as well as available test baseline information for the tests to be run. Using a predetermined algorithm, the list of the tests, and the available test baseline information, the scheduler automatically creates a plurality of testing schedules, such that a given test object cannot be simultaneously allocated to more than one test. Each of the plurality of schedules indicates test object allocation for the testing interval. Next, the scheduler selects one of the plurality of testing schedules based on reducing an overlap of test object allocation for the testing interval. The scheduler then communicates the selected testing schedule to be implemented by the network test system.

An embodiment of a tandem mass spectrometer comprises a first collision cell receiving analyte ions having an internal energy and a second collision cell situated downstream from the first collision cell wherein the first collision cell increases the internal energy of the analyte ions prior to entry of the ions into the second collision cell, the increase in internal energy imparted in the first collision cell alone being insufficient to fragment a substantial portion of the analyte ions. Another embodiment includes a collision cell with a heating device situated adjacent to the collision cell for controlling the temperature within the collision cell.

Abstract: An original composite eye diagram is reformulated by deliberately re-aligning its component eye diagrams according to some appropriate standard. This ‘forced-alignment’ shifts the components in one or both of the time and voltage axes. Notice is taken of the shift(s) for each channel, and that shift data is appended to the data structures for the original components. The content of the data structure can be read in its original form, or, read and force-aligned. A force-aligned composite eye diagram created from the re-aligned components can then be displayed, investigated and evaluated with any of the existing tools that used to analyze eye diagrams, simply by instructing the process that read a component eye diagram structure to reform that component as it is being read.
