Abstract: An application adapted to run within an enterprise wide, web-based framework which provides reusable services and facilities such as security, meta-data management and traceability of data and a framework supporting the same. The framework supports decision making across the value chain, with an emphasis on the meta-data needed for decision making. The framework can support the activities of a virtual organization (internal or external) and the inevitable variations in data types, file formats etc. without requiring massive integration between the various sources of data involved.

Abstract: A method for operating a data processing system to simulate a mixer having an RF port, a LO port, and an IF port. In the present invention, the signal leaving the IF port is approximated by: b2=f(a1,a3)+S22*a2 where S22 is a constant, a2 is a signal input to the IF port, a1 is a signal input to said RF port and a3 is a signal input to said LO port, and f ? ( a1 , a3 ) = ? i = o M ? ? j = o N ? C ij * a1 i * a3 j The coefficients Cij are constants that depend on said mixer design. These coefficients can be determined by measuring the b2 when a1 and a3 are single tone signals. In addition, the coefficients can be determined by simulating said mixer on a non-linear circuit simulator when a1 and a3 are single tone signals.

Abstract: The present invention relates to a method and to an apparatus for measuring an optical property, such as group delay or chromatic dispersion, of a DUT, comprising: a first coupler connected to the DUT for coupling a first optical signal having a first wavelength and a second optical signal having a second wavelength into the DUT, the second wavelength being variable with respect to the first wavelength, a detector connected to the DUT for detecting the first and the second signal leaving the DUT, an evaluation unit connected to the detector, for determining a difference in runtime, if any, between the first and the second signal having traveled at least one time through the DUT and for deriving the optical property from the detected difference.
Abstract: An apparatus for optically shifting the frequency of an input signal beam includes a first Raman medium that receives an input signal beam, a first pump beam, and a first reference beam to responsively generate an intermediate signal beam comprising a Raman sideband of the first Raman medium. A second Raman medium is optically coupled in series with the first Raman medium. The second Raman medium receives the intermediate signal beam, a second pump beam, and a second reference beam to responsively generate an output signal beam comprising a Raman sideband of the second Raman medium. The generated output signal represents the input signal that is shifted in frequency by a frequency shift that corresponds to the frequency difference between the first and second reference beams.

Abstract: Linearizing analog to digital converter (ADC) performance using single-bit dither. Dither is summed with an input signal to an ADC by passing a serial pseudo-random bitstream through an analog filter. Dither is removed through applying correlation and digital filtering to the ADC digital output.

Abstract: Calibration is performed for the testing of a device under test. A first port of the device under test is connected to a port of a calibration module. A second port of the device under test is connected to a first port of a device tester. A third port of the device under test is connected to a second port of a device tester. The device tester performs measurements by the device tester to obtain calibration parameters. In response to commands from the device tester, the calibration module changes termination values at the port of the calibration module. The changing of the termination values is performed without physical disconnection of the port of the calibration module from the first port of the device under test.

Abstract: An apparatus includes a polarization beam splitter, at least two reflectors and first and second polarization rotation devices. The polarization beam splitter and the at least two reflectors are arranged in a loop that is capable of propagating a clockwise signal component and a counterclockwise signal component. The first polarization rotation device is located in the loop between the polarization beam splitter and a first reflector of the at least two reflectors. The second polarization rotation device is located in the loop between the polarization beam splitter and an additional reflector of the at least two reflectors. The first polarization rotation device includes a serial arrangement of a reciprocal rotator and a nonreciprocal rotator.
Abstract: An optical heterodyne detection system includes an attenuator for attenuating an input signal before the input signal is combined with a local oscillator signal. An optimal attenuation level for the input signal, which improves the signal to noise ratio of the heterodyne beat signal, is determined by obtaining a base measurement of an output signal in response to the local oscillator signal and in the absence of the input signal, obtaining sample measurements of the output signal in response to the input signal as a function of different attenuation levels, and determining the optimal attenuation level as a function of the base measurement and the sample measurements. A minimum attenuation level for the input signal, which protects receiver photodetectors from being saturated or damaged, is determined by setting an initial attenuation level and gradually reducing the attenuation level until the voltage limit of the photodetectors is reached.

Abstract: An apparatus and method for making a microscopic paddle wheel coupled inductively by an external electromagnet and used for valving and active pumping so that the actual pumping mechanism is completely isolated from the electromagnetic driver. The paddle wheel is inexpensive to manufacture and disposable. A cartridge having a network of conduits and reservoirs contains several of such paddle wheels to transport blood and reagents. A point-of-care device houses the electromagnetic driving mechanism and is reused with successive cartridges since the paddle wheels are contained by the cartridge and do not contaminate the driving mechanism.

Abstract: A list of waveforms is received (the list being one that is to be driven to or received from a pin of a device under test). The list of waveforms is de-interleaved to form lists of non-interleaved waveforms. Each list of non-interleaved waveforms is then optimized by combining at least two of its entries. By way of example, the above method may be implemented by program code stored on a number of computer readable media, or by a circuit tester having program code for implementing same.
