| 20100212412 | METHOD OF DISPLAYING CONTOURS OF A SURFACE OF A BEARING - Contours of a surface of a bearing which extends about an axis are displayed on a grid. To visualize the contours, points on the surface are measured at a plurality of angular positions to determine the corresponding measured values. The measured values at each angular position are normalized to determine a normalized measurement datum corresponding to each angular position. The normalized measurement datum is subtracted from each of the measured values to determine a plurality of deviations of the corresponding points. Shades are assigned that correspond to a range of possible deviations. Each of the deviations are displayed as a data segment on a grid that represents the shape of the surface of the bearing. Each data segment is shaded on the grid to the corresponding shade to provide a topographical representation of the contours of the surface of the bearing. | 08-26-2010 |

| 20110095791 | LOW-POWER OSCILLATOR - Techniques for synthesizing a signal having a desired frequency from an oscillation signal. In an aspect, a reference signal having a known frequency may be periodically used to determine a ratio between the desired frequency and the frequency of the oscillation signal. The oscillation signal may be decimated by the ratio to generate a synthesized signal having approximately the desired frequency. In an aspect, the decimation may be performed by generating a pulse in response to the output of an accumulator that accumulates in steps of the ratio. To save power, the oscillation signal may be derived from a low-power oscillator, while the reference signal may be turned on only during periodic calibration. Further aspects for improving the frequency accuracy of the synthesized signal are disclosed. | 04-28-2011 |

| 20090108949 | TEMPERATURE COMPENSATION FOR CRYSTAL OSCILLATORS - Methods and apparatus for generating a temperature compensated frequency estimate for a crystal oscillator, wherein the temperatures of the crystal and oscillator are both accounted for. A crystal temperature measurement is used to generate a first frequency component. The difference between the oscillator temperature measurement and a second temperature is scaled, and used to generate a second frequency component. The first and second frequency components may be summed to produce a frequency estimate for the crystal oscillator. In an embodiment, the computations may be performed in the slope domain. | 04-30-2009 |
| 20090195322 | CRYSTAL OSCILLATOR FREQUENCY CALIBRATION - Techniques are disclosed for estimating a frequency of a crystal oscillator based on temperature. In an embodiment, the oscillator frequency is computed using a polynomial approximation. Techniques are disclosed for deriving and periodically updating the coefficients used in the polynomial approximation. | 08-06-2009 |
| 20090279591 | FREQUENCY SPUR DETECTION AND SUPPRESSION - Techniques for identifying and suppressing frequency spurs in a signal are disclosed. In an embodiment, an incoming signal is rotated by a frequency related to a spur frequency, and an estimate of the content of the rotated signal is derived. The estimate may be subtracted from the rotated incoming signal, and the result de-rotated by the spur frequency. In an embodiment, the incoming signal may be rotated such that the spur is centered at DC. In an alternative embodiment, the estimate may be de-rotated before being subtracted from the original incoming signal. Techniques for addressing multiple spurs using serial and parallel architectures are disclosed. Further disclosed are techniques for searching for the presence of spurs in an incoming signal, and tracking spur frequencies over time. | 11-12-2009 |
