  • Patent number: 7397865
    Abstract: A system analyzer may generate an estimated frequency response of a device, system, communication medium, or combination thereof by utilizing a stimulus signal that is robust against IQ modulator impairments. A stimulus generator may be used to generate a plurality of discrete tones according to a frequency spacing and a frequency offset. The frequency spacing and the frequency offset cause spectrally inverted spurs (generated by impairments of the IQ modulator) to occur at frequencies other than frequencies of said modulated signal that are associated with said plurality of discrete tones. Additionally, by implementing a Discrete Fourier Transform (DFT) to possess a frequency resolution equal to the frequency offset, there is no leakage of power associated with the spectrally inverted spurs into frequency bins of the DFT associated with the desired frequency components. Likewise, leakage between the desired frequency components and leakage associated with the local oscillator may be avoided.

  • Patent number: 7397542
    Abstract: For determining mode spectra of an optical property of a device under test (DUT) in dependence on a spectral parameter, with the mode spectra corresponding to the device's principal states of polarization (PSPs), minimum and maximum envelope values are determined for the optical property, or other measured values from which the envelope values can be determined with respect to possible state of polarization of light that is incident upon the DUT, whereby the minimum envelope values and the maximum envelope values are determined for a spectral range of interest of the spectral parameter. The mode spectra are derived for the optical property for at least one of the PSPs as a function of the spectral parameter for the spectral range of interest, whereby a partial correspondence of the mode spectra with the minimum and maximum envelope values is used for deriving the mode spectra.

  • Patent number: 7397543
    Abstract: Determining a physical property of a device under test—DUT—includes receiving an optical scatter signal returning from the DUT in response to a probe signal launched into the DUT, wavelength dependent separating a first response signal and a second response signal from the scatter signal, determining a first power information of the first response signal and a second power information of the second response signal, time-adjusting the first power response and the second power response to each other in order to compensate a group velocity difference between the first response signal and the second response signal within the DUT, and determining the physical property on the base of the time-adjusted power responses.

  • Patent number: 7394058
    Abstract: A touch indication device comprises a light guide structure for passing light of a light source via total internal reflection. A touch surface disturbs the total internal reflection when touched, causing light to leave the light guide structure. A light enhancement layer converts the light leaving the light guide and sends the converted light to a light detector. The light enhancement layer amplifies the intensity and/or changes the color of the light leaving the light guide. The detector determines the position of the touch on the touch surface based on the light from the light enhancement layer.
