Abstract: Methods and systems for tracking an electronic signal corresponding to an operating frequency of an electronic component are provided. A method may include sampling the signal to determine previous and current time samples of the signal. A frequency of interest in the signal may also be pre-warped to decrease adverse warping effects resulting from processing signals having relatively higher operating frequencies.

The digital tracking filter may be configured to execute one or more algorithms on the previous and current time samples and the pre-warped frequency of interest to estimate a current operating frequency.

Abstract: Systems and methods are provided that may include employing a lockscrew to provide radial and axial force in connecting tubular members in a mineral extraction system. The lockscrew may be angled relative to the tubular members, at an angle that is greater than 0 degrees and less than 90 degrees. Further, the lockscrew may have an end portion which mates with a slot in a locking segment, and the lockscrew and locking segment may be moved from an unlocked to a locked position. In a locked position, the lockscrew exerts force axially downward and radially inward to push the locking segment against a tubular member, locking the member in place. The interconnection between the lockscrew and the locking segment may enable easier installation and may utilize parts which may be easier to manufacture. Furthermore, the angle of the lockscrew may provide improved support for tubular members.

Abstract: A load control system, in certain aspects, may be configured to decrease the amount of noise pollution of a prime mover (e.g., engine) of a service pack in that it may not require the prime mover to operate at higher discrete operating speeds to deliver small amounts of air from the air compressor. The load control system may also only increase the speed of the prime mover to a minimum discrete speed required, keeping noise at a minimum. The load control system may also maximize fuel efficiency by not operating the prime mover at the highest discrete speed at all times. More specifically, the lower operating speeds may lead to less fuel consumption.

Abstract: A technique for selecting portions of a multi-resolution medical image data set to be stored and the portions of the multi-resolution medical image data set to be discarded in order to reduce the overall amount of image data that is stored for each image data set. The selection is based on the clinical purpose for obtaining the medical image data. The clinical purpose for obtaining the medical image is used to select a segmentation algorithm to segment the image data into several regions based on their relevance to the purpose for obtaining the image data. A mask is created from the segmented data. The mask is used to assign data compression quality factors to corresponding regions in the image data. The image data in each region is compressed based on their assigned quality factor. The image data that is highly relevant is compressed with lossless data compression. The image data in regions of lesser relevance are compressed with lossy data compression.
