Abstract: A system and method for codebook-based data encoding. Portions of the data are encoded by different encoding libraries, depending on which library provides the greatest compaction for a given portion of the data. This methodology not only provides substantial improvements in data compaction over use of a single data compaction algorithm with the highest average compaction, but provides substantial additional security in that multiple decoding libraries must be used to decode the data. In some embodiments, each portion of data may further be encoded using different sourceblock sizes, providing further security enhancements as decoding requires multiple decoding libraries and knowledge of the sourceblock size used for each portion of the data. In some embodiments, encoding libraries may be randomly or pseudo-randomly rotated to provide additional security.

Abstract: A system and method for distributed node-based data compaction. The system uses machine learning on data chunks to generate codebooks which compact the data to be stored, processed, or sent with a smaller data profile than uncompacted data. The system uses a data compaction in an existing blockchain fork or implemented in a new blockchain protocol from which nodes that wish to or need to use the blockchain can do so with a reduced storage requirement. The system uses network data compaction across all nodes to increase the speed of and decrease the size of a blockchain's data packets. The system uses data compaction firmware to increase the efficiency at which mining rigs can computationally validate new blocks on the blockchain. The system can be implemented using any combination of the three data compaction services to meet the needs of the desired blockchain technology.

Abstract: A system and method for manipulation of compacted data files, utilizing a reference codebook, a random-access engine, a data deconstruction engine, and a data deconstruction engine. The system may receive a data query pertaining to a data read or data write request, wherein the data file to be read from or written to is a compacted data file. A random-access engine may facilitate data manipulation processes by accessing a reference codebook associated with the compacted data file, a frequency table used to construct the reference codebook, and data query details. A data read request is supported by random-access search capabilities that may enable the locating and decoding of the bits corresponding to data query details. A random-access engine facilitates data write processes. The random-access engine may encode the data to be written, insert the encoded data into a compacted data file, and update the codebook as needed.

Abstract: A system and method for data compression with encryption, that produces a conditioned data stream by replacing data blocks within an input data stream to bring the frequency of each data block closer to an ideal value, produces an error stream comprising the differences between the original data and the encrypted data, and compresses the conditioned data.

Abstract: A system and method for compacting data that uses mismatch probability estimation to improve entropy encoding methods to account for, and efficiently handle, previously-unseen data in data to be compacted. Training data sets are analyzed to determine the frequency of occurrence of each sourceblock in the training data sets. A mismatch probability estimate is calculated comprising an estimated frequency at which any given data sourceblock received during encoding will not have a codeword in the codebook. Entropy encoding is used to generate codebooks comprising codewords for data sourceblocks based on the frequency of occurrence of each sourceblock. A “mismatch codeword” is inserted into the codebook based on the mismatch probability estimate to represent those cases when a block of data to be encoded does not have a codeword in the codebook. During encoding, if a mismatch occurs, a secondary encoding process is used to encode the mismatched sourceblock.

Abstract: A system and method for data compaction and encryption of anonymized data records. A dataset may be pre-processed by dividing into a plurality of sourceblocks at all reasonable sourceblock lengths, and then counting how many times each sourceblock occurs in the dataset, resulting in a tally record of tokens and their count value. This tally record may then be anonymized and transmitted to a data deconstruction engine which combined with a library manager creates a codebook and performs optimization techniques on the codebook. The received anonymized tally record may be parsed into individual tokens by identifying the tokens with the highest count value. The tokens may then be sent, in descending order of count value, to the library manger where each token may be assigned a codeword. A half-backed codebook is then created using the tokens and each token's unique codeword, before sending the half-backed codebook to a system user.

Abstract: A system and method for encrypted data compression, which uses frequency analysis on data blocks within an input data stream to produce a prefix table, representing a first layer of transformation, and which applies a Burrow's-Wheeler transform (BWT) to the data inside the prefix table, representing a second layer of transformation, and which compresses the transformed data. In some implementations, the system and method may further include applying the BWT to a conditioned stream of genomic data, wherein the conditioned stream of data is accompanied by an error stream comprising the differences between the original data and the encrypted data.

Abstract: Systems and methods presented herein include sidewall coring tool assemblies used to return core plugs of rock from a sidewall of a wellbore as part of a data collection exercise for exploration and production of hydrocarbons. A coring bit and a coring shaft of the present disclosure allow space for cuttings to move away from the bit face when drilling into a formation. In addition, certain embodiments include a plurality of inlets disposed circumferentially on an external surface at a first axial end of the coring shaft, a plurality of internal grooves disposed on an internal surface of the coring shaft, and/or a plurality of fins disposed on the external surface to direct flow of drilling and debris away from the coring bit. In addition to providing more space for cuttings to move away from the coring bit, the torque needed to drive the bit is lessened as the surface area of the bit contacting or engaging the formation is reduced.

Abstract: A vehicle bumper that incorporates a "C" section face bar attached to a truss-formed backplate to achieve a box section construction. The face bar, although a conventional "C" section, has more nearly horizontal upper and lower shelves combined with a reduced frontal face height to offer, when further combined with the backplate, a nearly square box beam. Functional height is extended beyond the beam section with a plurality of strategically located underride stops drawn from the lower shelf. These stops provide low pendulum impact performance at minimal weight while facilitating forming of the bumper beam ends. The stops preferably are concealed with a flexible shield which provides conventional appearance in addition to opportunities of cost, weight, airflow and model appearance differentiation when replacing separate air deflectors and sight shields. The bumper assembly configuration provides a highly weight efficient section modulus, improved torsional stiffness and improved dent resistance.

Abstract: A self-deployable front air spoiler assembly mounted beneath a vehicle underbody, the air spoiler assembly comprising a laterally extending airfoil which in non-deployed condition is situated in a semi-concealed position. The airfoil is supported at each side of the longitudinal center of the vehicle on swingable links, each link being pivotally coupled at one end to the airfoil and at the other end to the vehicle underbody. The pivot axes of the links are substantially parallel to the airfoil. Biasing means interposed between the air spoiler assembly and the vehicle underbody normally biases the airfoil toward its deployed condition. As the air pressure against the front face of the airfoil increases as the speed of the vehicle is increased, the airfoil swings downwardly increasing the frontal area impacted by the airstream and restricting the flow of air beneath the vehicle underbody.

Abstract: The combination of a laterally extending bumper mounted on the front end of a vehicle and a chin spoiler mounted beneath the bumper, the vehicle bumper having an ornamental face bar and a reinforcement member concealed therebehind. The chin spoiler comprises a support means fastened by conventional fastening means to the bumper reinforcement and an airfoil. The airfoil is contoured along its leading edge to complement the frontal contour of the bumper face bar. A hinge means secures the airfoil along its rear edge to the support means rearwardly of the bumper reinforcement. Biasing means interposed between the support means and the airfoil normally biases the latter towards the underside of the bumper face bar in a concealed position beneath the vehicle. The hinge means provides a hinge axis extending laterally of the vehicle about which the airfoil is deployable.
