  • Patent number: 10900714
    Abstract: There is provided an apparatus for use in drying a sample of geological material having a substantial moisture content. In one aspect, the apparatus comprises a means for providing a flow of heated fluid, and a means for managing the thermal state of the flow of heated fluid. The means for managing the thermal state of the flow of heated fluid is arranged operable with the means for providing a flow of heated fluid so that exposure of the sample to the flow of heated fluid facilitates a reduction of the moisture content of a portion of the sample while substantially preserving one or more chemical and/or physical properties of the portion.

  • Patent number: 10234554
    Abstract: Embodiments described herein simplify the recognition of objects in synthetic aperture radar (SAR) imagery. This may be achieved by processing the image in order to make the shadow caused by the object appear more similar to the object. Alternatively, this may be achieved by processing the image in order to make the layover caused by the object appear more similar to the object. Manipulation of the shadow caused by the object and the layover caused by the object may comprise altering the aspect ratio of the image, and in the case of manipulating the shadow caused by the image, may further comprise transforming the image by reflection or rotation. The aspect ratio of the image may be altered based on information about the image collection geometry, obtained by the SAR.

  • Patent number: 8390358
    Abstract: Integrated jitter compliant clock signal generation apparatus and methods are provided. Input signals having different frequencies are used to generate respective clock signals having closely spaced frequencies. The input signals might be generated, for example, in adjacent Phase Locked Loops (PLLs) which receive reference clock signals. The reference clock signals, or signals from which the reference clock signals originate, are also closely spaced. The closely spaced reference clock signals are effectively separated for cleanup and then brought back together to provide the closely spaced clock signals. This allows cleanup of the closely spaced reference clock signals to occur at staggered and more widely spaced frequencies. These techniques could also be applied to reference clock signals which are harmonically related and are used to generate harmonically related output clock signals.

  • Patent number: 8384452
    Abstract: A phase difference between a reference clock signal and a feedback signal is digitally detected. A resultant phase detection signal is digitally filtered, and a PLL (Phase Locked Loop) output signal is synthesized in a fractional synthesizer under control of the digitally filtered phase detection signal. A feedback path, which could include an integer divider and/or a fractional N divider, provides the feedback signal based on the PLL output signal. The combination of a wide bandwidth fractional synthesizer and a low bandwidth digital PLL provides for a low bandwidth jitter filtering function with a wide bandwidth PLL to suppress VCO (Voltage Controlled Oscillator) noise and crosstalk.

  • Patent number: 7848474
    Abstract: Signal timing phase selection and timing acquisition apparatus and techniques are disclosed. A timing phase that is most closely aligned with a phase of information carried by a received signal is selected from a plurality of timing phases. The selected timing phase may be used, for example, as a reference signal for a phase detector in a Phase-Locked Loop (PLL). The received signal may be sampled one or more times per timing phase. In a multiple-sample implementation, the samples may be used for timing phase selection, for detection of a known initial pattern of a burst of information to thereby detect the start time of a an information burst, or both.

  • Patent number: 7519750
    Abstract: The present invention discloses a host receiver synchronizer for passive optical networks, and in particular a burst clock data recovery circuit in a host receiver in a bursty asynchronous communication system having a non-data preamble of less than 250 ns, for recovering a clock signal from a subscriber data burst. The circuit comprises: an adjustable oscillator for generating an output clock signal in response to a signal at an input thereof; a first comparator for comparing a frequency and phase of the output clock signal to that of a reference signal and feeding back a first feedback signal to the oscillator input; and a second comparator for comparing the frequency and phase of the output clock signal to that of the data burst and feeding back a second feedback signal to the oscillator input once the output clock signal is locked in frequency with the reference signal. The output clock signal is locked in frequency and phase to the data burst before receipt of the last bit of the preamble.

  • Patent number: 7308060
    Abstract: An eye opener circuit is provided which performs a data re-timing/eye opening function on a data signal after having been corrupted by jitter. The circuit uses a PLL driven by a clock source which was the same clock source used in timing the data signal originally. The PLL generates a local clock used to re-time the data. A phase error may be introduced into the PLL, or into the data signal.
