Publication number: 20240117720Abstract: A plunger for use in an oil or gas well that includes a mandrel and a hollow body with radial directed ports disposed therein. The plunger also includes a variable flow mechanism that can be adjusted to achieve a desired fall rate for the plunger for a particular oil and gas operation. A method of lifting fluids from an oil and gas well using the plunger includes the step of employing an adjustable plunger to lift fluids from the oil and gas well wherein the adjustable plunger has a desired fall rate in the well.Type: ApplicationFiled: October 9, 2023Publication date: April 11, 2024Inventors: Jack Rogers, Travis Bayer, Ryan Gernentz

Patent number: 11601280Abstract: A first string, having a first string value, that is associated with a sample set of material is received, wherein a second string, having a complementary value relative to the first string value, is also associated with the sample set of material. A determinative hash is generated using the first string value and a symmetric generator polynomial. A second hash, corresponding to the second string, is generated directly from the determinative hash. A canonized hash is generated using the determinative hash and the second hash. It is determined whether at least one of the first string or the second string is stored in string storage that is configured to store a plurality of strings, including by searching a hash table for the canonized hash; in the event it is determined that at least one of the first string or the second string is not stored in the string storage, at least one of the first string or the second string is stored in the string storage.Type: GrantFiled: February 25, 2021Date of Patent: March 7, 2023Assignee: OmniTier Storage, Inc.Inventors: Jonathan Darrel Coker, Travis Roger Oenning, Balamurugan Anandan

Patent number: 10965467Abstract: A first string, having a first string value, that is associated with a sample set of material is received where a second string, having a complementary value relative to the first string value, is also associated with the sample set of material. A reversible hash generator is used to generate a determinative hash using the first string value, where a second hash, corresponding to the second string, is able to be determined directly from the determinative hash and without the reversible hash generator processing the complementary value of the second string. It is determined whether at least one of the first string or the second string is stored in a memory using the determinative hash.Type: GrantFiled: October 13, 2020Date of Patent: March 30, 2021Assignee: OmniTier Storage, Inc.Inventors: Jonathan Darrel Coker, Travis Roger Oenning, Balamurugan Anandan

Publication number: 20170318338Abstract: The present principles of the embodiments generally relate to an apparatus and a method for downloading of media content. In one exemplary embodiment, a mechanism for downloading multiple media assets in the form of a batch download is dependent on a profile of user which takes into account of media content consumption habits or behavior of a user. The mechanism can be used, for example, to efficiently download multiple episodes of a show such as, e.g., a television series.Type: ApplicationFiled: October 19, 2015Publication date: November 2, 2017Inventors: Travis ROGERS, Arnaud RETUREAU

Publication number: 20170230706Abstract: The present principles of the embodiments generally relate to an apparatus and a method for downloading of media content and particularly for downloading a plurality of episodes for a show such as e.g., a television series. In one exemplary embodiment, if sufficient space is not available for the selected plurality of episodes of the show, then at least one already downloaded and watched episode of same show is deleted. Another episode not yet downloaded will then be downloaded to fill a space vacated by the deleted downloaded and watched episode of the same show.Type: ApplicationFiled: July 28, 2015Publication date: August 10, 2017Inventors: Travis ROGERS, Arnaud RETUREAU

Patent number: 9059737Abstract: Disk drives are described in which blocks of data spanning multiple sectors are encoded into a plurality of codewords which are then divided into segments that are physically separated (distributed) on the disk surface over multiple sectors in a distributed codeword block so that the codewords have an improved worst case SNR in comparison to individual sectors. This results in more even SNR performance for each codeword, which improves the performance for portions of a track which have lower than the average SNR. Embodiments are described in which the distributed codeword blocks span across tracks.Type: GrantFiled: May 1, 2013Date of Patent: June 16, 2015Assignee: HGST Netherlands B.V.Inventors: Jonathan Darrel Coker, Richard Leo Galbraith, Weldon Mark Hanson, Travis Roger Oenning, Roger William Wood

Publication number: 20150116860Abstract: Techniques for processing signals read-back from a disk of a hard disk drive are described. In one example, a hard disk drive device generates a signal associated with a first position within a width of the data track. The first position may correspond to the center of a data track. The hard disk drive device generates a signal associated with a second position within a width of the data track. The second position may be located at a distance of approximately 10% of the track width from the track center. The hard disk drive device combines the signals and applies as signal conditioning technique to the combined signal.Type: ApplicationFiled: October 28, 2013Publication date: April 30, 2015Applicant: HGST Netherlands B.V.Inventors: Jonathan Darrel COKER, Richard Leo GALBRAITH, Travis Roger OENNING, Roger William WOOD

Patent number: 8988807Abstract: A hard disk drive has disks with data sector preambles that allow for inter-track interference. The same data sector preamble is used for all data sectors in a track but the preamble in each track is different from the preamble in radially adjacent tracks. In a first embodiment each preamble includes a synchronization field (SF) and synchronization mark (SM) that are the same in each track but different from the SF and SM in radially adjacent tracks. Only two unique SFs and two unique SMs are required, with the two SFs and two SMs alternating in radially adjacent tracks. In a second embodiment the preambles are “integrated”, meaning that the preamble is a sequence of bits that does not include separate dedicated fields, like SF and SM. The preamble bit sequences are decoded using matched filters to provide bit synchronization and start-of-data information.Type: GrantFiled: September 19, 2013Date of Patent: March 24, 2015Assignee: HGST Netherlands B.V.Inventors: Jonathan Darrel Coker, Richard Leo Galbraith, Weldon Mark Hanson, Travis Roger Oenning, Srinivasan Surendran

Patent number: 8649215Abstract: A Flash memory system and a method for data management using the system's sensitivity to charge-disturbing operations and the history of charge-disturbing operations executed by the system are described. In an embodiment of the invention, the sensitivity to charge-disturbing operations is embodied in a disturb-strength matrix in which selected operations have an associated numerical value that is an estimate of the relative strength of that operation to cause disturbances in charge that result in data errors. The disturb-strength matrix can also include the direction of the error which indicates either a gain or loss of charge. The disturb-strength matrix can be determined by the device conducting a self-test in which charge-disturb errors are provoked by executing a selected operation until a detectable error occurs. In alternative embodiments the disturb-strength matrix is determined by testing selected units from a homogeneous population.Type: GrantFiled: December 22, 2010Date of Patent: February 11, 2014Assignee: HGST Netherlands B.V.Inventors: Luiz M.
