  • Patent number: 10135531
    Abstract: An optical transmission system transmits an optical signal over an optical path. Reflections of the optical signal are received at an optical detector which generates an analog reflection signal. The analog reflection signal includes both a desired portion and an undesired portion. Correlators of an OTDR system generate correlation values based on the analog reflection signal. A subset of the correlation values are associated with locations of the optical path that cause the reflections that result in the undesired portion of the reflected signal. A filter uses these correlation values to generate a cancellation signal that is subtracted from the analog reflection signal, reducing the undesired portion of the signal that must be processed.

  • Patent number: 9784601
    Abstract: A system is described for time synchronizing digitized measurement signals, such as vibration signals. The digitized signals, which are acquired asynchronously by multiple distributed measurement units, indicate the operational condition of a machine or a process. To measure the phase of the digitized signals relative to a pulse tachometer input, the time between the leading edge of the tachometer pulse and the digitized samples is measured. To achieve phase-coherent synchronization across the distributed measurement units, a local synchronization signal is embedded into the data produced by the measurement units. The systems uses the synchronization signal to align the data in post processing, which phase aligns the data and aligns the data in absolute time. The synchronization signal may be encoded with a timestamp to provide additional timing information.

  • Patent number: 9425778
    Abstract: A continuously adaptive timing calibration function for a data interface is disclosed. A first calibration method is performed for a mission data path, typically at power-on, to establish an optimal sample point. Reference data paths are established for a second calibration method that does not disturb normal system operation. Data bit edge transitions are examined at fringe timing points on either side of the optimal sample point. Assuming that a timing change for the edge transitions indicates a drift of the optimal sample point, when a drift amount is determined to be greater than a correction threshold value the optimal sampling point for the mission path is adjusted accordingly. At no point does the continuous calibration function determine that any data bit is invalid since the optimal sampling point is always maintained. Also, at no point does continuous calibration require successive alternating data bit values such as 1-0-1 or 0-1-0.

  • Patent number: 8935127
    Abstract: A method for recording pulse signals which allows the reconstruction of a time reference. The time of every pulse signal event can be determined by counting sampling result bits preceding the respective sampling result bit using the known sampling frequency. For this purpose, every period of the sampling frequency is associated with a bit representing the respective sampling result and the sampling result bits are stored one by one and per channel in data blocks. The sampling frequency is preferably higher than a pixel clock, a sampling result bit associated with a flank of the pixel clock being marked. The pixel clock can thus be synchronized with the individual events exactly per sampling period. The invention further relates to the field of fluorescence correlation spectroscopy using confocal microscopes or laser scanning microscopes.

  • Patent number: 8903670
    Abstract: In a receiver of electromagnetic or other waves, scaling of received frequencies in proportion to the respective source distances, so as to reveal the source distances and permit isolation of signals from a particular source by simple spectral filtering. Phase differences between transmitted frequencies due to the common source path lead to chirp eigenfunctions registering in the receiver as scaled frequencies. The chirps are extracted by implementing exponentially varying path delays in autocorrelators and diffractive spectrometers say using a medium with variable refractive index. Analogous exponentially varying phase shifts are applied to successive samples in the kernel of discrete Fourier transform implementations. Advantage lies in enabling distance-dependent frequency scaling in autocorrelation spectroscopy, as well as in conventional diffractive or refractive spectrometers or digital signal processing with uniform sampling.

  • Patent number: 8824532
    Abstract: A method of generating a noisy receive signal for testing the performance of a mobile wireless communication device is described. A signal generator unit generates a transmit signal that frequency hops among a set of carrier frequency channels in a cyclic pattern having a time duration T. A wireless channel emulator unit generates a receive signal by modifying the transmit signal and also generates an interference signal by modifying the receive signal. The wireless channel emulator unit delays the interference signal relative to the receive signal by an integer multiple of the time duration T. The receive signal and the interference signal are combined by a combiner unit to generate the noisy receive signal.

  • Patent number: 8779787
    Abstract: Apparatus and method for determining variation in a predetermined physical property of a circuit. The apparatus includes monitored circuitry for generating output pulses, and configured such that each output pulse has a pulse width which is indicative of the current value of the predetermined physical property. Circuitry is then configured to receive both the output pulses generated by the monitored circuitry and an oscillating timing reference signal. With reference to the oscillating timing reference signal, the counter circuitry produces for each output pulse an associated count value indicative of the pulse width of that output pulse. Circuitry then compares the associated count values for at least two output pulses, in order to produce a comparison result used to determine the variation in the predetermined physical property. This provides a flexible mechanism for monitoring variations in a physical property on the fly during use of a data processing circuit.

  • Patent number: 8762097
    Abstract: In one aspect, a data processing system includes a virtual temperature sensor to provide system temperature for different system configurations, and a controller coupled to the sensor to control operations of the data processing system according to the virtual temperature. The virtual temperature sensor typically derives the temperature of a particular configuration of the data processing system using mathematical models or one or more operating parameters of the data processing system. In one example, the mathematical models include a characterization table which provides the measured temperature data from various system configurations. These measurements are performed with temperature sensors positioned in ideal locations for different configuration, and are preprocessed to provide the virtual temperature computation. The characterization table also includes thermal characteristics, such as thermal time constant and thermal resistance, of the critical components at multiple thermal control states.

  • Patent number: 8751097
    Abstract: A method and system for using Equivalent Time Sampling to improve the effective sampling rate of sensor data, and using the improved-resolution data for diagnosis and control. Data samples from existing sensors are provided, where the sampling rate of the existing sensors is not sufficient to accurately characterize the parameters being measured. High-resolution data sets are reconstructed using Equivalent Time Sampling. High-resolution input data sets are used in a system model to simulate the performance of the system being measured. Results from the system model, and high-resolution output data sets from Equivalent Time Sampling, are provided to an estimator, which provides accurate estimation of measured quantities and estimation of quantities not measured. Output from the estimator is used for fault diagnosis and control of the system being measured.
