  • Patent number: 8352203
    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 previous and current time samples of the signals, along with the pre-warped frequency of interest, may be input into a digital tracking filter. 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.

  • Patent number: 8347970
    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.

  • Patent number: 8342150
    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.

  • Patent number: 8345991
    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.

  • Patent number: 8338971
    Abstract: A system and method are provided for controlling an internal combustion engine driving a generator/welder or a stand-alone generator. Controlling the engine may include altering the engine speed based upon a detected demand on the generator and/or operating parameters of a welder. For example, the engine speed may be increased based on a detected draw on the generator and/or the operating parameters of the welder. In addition, the engine speed may be automatically decreased to a non-standard idle speed or the engine may be automatically turned off if no demand is detected for a period of time. Additionally, the engine speed may be increased if only frequency-insensitive demands are detected on the generator. Combinations of these and further methods may be executed. Various devices are provided for implementing the above methods.

  • Patent number: 8338986
    Abstract: A method for providing power to devices in a network and coordinating actions of multiple power supplies on the network is described. The method may include maintaining connectivity of communication signals and ground between upstream and downstream portions of the network relative to a power supply, while terminating power from an upstream power supply and taking over power supply functions for downstream devices. This may be achieved by including a logic feature within one or more of the multiple power supplies that monitors a power status of an upstream power supply and/or the power status of the associated power supply. When the logic feature detects a power cycle, it initiates a coordinated power cycle of the associated power supply and/or other networked power supplies.

Each rectifier circuit may also include three inputs for three-phase AC power coupled to alternating vertices of the hexagonal representation and nine outputs for AC power coupled between each node that is not a vertex of the hexagonal representation and a respective diode bridge. Outputs of the diode bridges for the rectifier circuits may be coupled to a DC bus. In addition, a means for reducing circulating current between the parallel rectifier circuits and for promoting load sharing between the parallel rectifier circuits is also provided.
