  • Publication number: 20220019925
    Abstract: The invention is ontology-based architecture for performing semantic data mining for insights. The major components of the architecture are illustrated using Network Ontology (NO), an ontology generated for the network domain for delivering improved network management. In addition, algorithms for summarizing performance profiles in the form of rank tables and for extracting insight rules (concrete action plan) from the rank tables are presented. By using this approach, an actionable plan for assisting decision maker can be obtained, as domain knowledge is incorporated in the system. Experimental results on a network dataset show that this model provides an optimal action plan for a network to improve its performance by encoding data-driven rules into the ontology and suggesting changes to its current network configuration.

  • Publication number: 20210389931
    Abstract: Disclosed herein are three context-aware architectures to accelerate the three state-of-the-art deterministic methods of SC. The proposed designs employ a control unit to extract the minimum bit-width required to precisely represent each input data. The lengths of bit-streams are reduced to the minimum lengths required to precisely represent each input data. The noise-tolerance property of the designs is preserved as each bit-flip can only introduce a least significant bit error. The proposed designs achieve a considerable improvement in the processing time at a reasonable hardware cost overhead. The proposed designs make the deterministic bit-stream processing more appealing for applications that expect highly accurate computation and also for error-tolerant applications.

  • Publication number: 20210383264
    Abstract: Efficient hardware design of the fuzzy-inference engine has become necessary for high-performance applications. The disclosed technology applies unary processing to the platform of fuzzy-logic. To mitigate the latency, the proposed design processes right-aligned bit-streams. A one-hot decoder is used for fast detection of the bit-stream with maximum value. Implementing a fuzzy-inference engine with 81 fuzzy-inference rules, the disclosed architecture provides 82%, 46%, and 67% saving in the hardware area, power and energy consumption, respectively, and 94% reduction in the number of used LUTs compared to conventional binary implementation.

  • Patent number: 11166057
    Abstract: Video streams, either in form of on-demand streaming or live streaming, usually have to be transcoded based on the characteristics of clients' devices. Transcoding is a computationally expensive and time-consuming operation; therefore, streaming service providers currently store numerous transcoded versions of the same video to serve different types of client devices. Due to the expense of maintaining and upgrading storage and computing infrastructures, many streaming service providers recently are becoming reliant on cloud services. However, the challenge in utilizing cloud services for video transcoding is how to deploy cloud resources in a cost-efficient manner without any major impact on the quality of video streams. To address this challenge, in this paper, the Cloud-based Video Streaming Service (CVSS) architecture is disclosed to transcode video streams in an on-demand manner.

  • Patent number: 11098836
    Abstract: The disclosed invention provides a device and method to detect leaks in pipelines and heal them instantly using twin ball technology. The device comprises two twin balls of novel construction inserted into the pipeline. The sensor ball receives acoustical data through internal sensors. Once the threshold of the sound level is surpassed, the smart ball will send a signal to the second flowing ball. The second ball will flow towards the leaking outlet and eject a healing fluid to close the leak and prevent further damage. The sensor ball will also alert the user to the size and location of the leak via Wi-Fi monitoring and text messaging. This twin balls technology could be used in pipelines of varying sizes and flow rates.

  • Patent number: 11028306
    Abstract: GSH Dry Lubricant Additive is, chemically, magnesium aluminum silicate. It is a clay rich in titanium, magnesium, and aluminum. As an inanimate object, it does not “function” per se, but rather its properties are as such that it is highly beneficial to the drilling industry. It has a naturally high lubricity, a high stall torque, high gel strength, but a low plastic viscosity. This means that it effectively cools the bit while drilling, reduces friction in the system, supports cuttings better, but is easier to break out of a static gel strength than traditional engineered muds. Finally, as a high suspendability, low solids content material, it acts as a natural gel-state cement for unconsolidated LCM particles, effectively strengthening the wellbore.

  • Patent number: 11020758
    Abstract: Flow blurring injection utilizes a two-phase concept to generate fine sprays immediately at the interior exit, rather than a typical jet which gradually disintegrates into ligaments and then finer droplets for a conventional injector. Therefore, clean combustion is achieved with the FB injection for fuels with distinct properties without fuel preheating or hardware modification. However, in addition to the droplets, the FB injection also produces ligaments for highly viscous liquids and relatively larger droplets at spray edge, resulting in difficulty in sustaining the flame and performs incomplete combustion and higher emissions close to the combustor all. The disclosed swirl burst injector and method utilizes the advantages of FB injection and swirl atomization to further improve atomization, and overcomes the limitations of FB injection, providing a sustainable way to use both conventional and alternative fuels with improved efficiency and minimized emissions.

  • Patent number: 10970453
    Abstract: The method for creating integrated circuits (IC) protects the design of a manufactured IC from being copied or counterfeited. This method protects the design of an IC chip from deliberate copying and counterfeiting by reverse engineering to gain access to the critical points in the IC chip and to siphon its functions and design. The method makes the copying, counterfeiting, and controlling by addition of Trojan circuits during manufacturing almost impossible task. It also allows chip designers to outsource the final bonding of the tiers without any fears that their design may get compromised.

  • Patent number: 10946126
    Abstract: A positive displacement pump that triggers with the beating of a mammalian heart, through the monitoring of an ECG signal is disclosed. A programmable delay from the detection of the forthcoming contraction of the heart enables the pump to syncopate the ejection of the fluid with the events occurring in the cardiovascular system. This delayed ejection could be used to overlay the ejected fluid from the pump with a pressure wave in the artery of systemic circulation through a catheter connection between the pump and a physiological model (e.g., cow, dog, human). The outcome of this use could be to raise the pulse pressure in the system to take advantage of physiological pathways that respond to this transient change in blood pressure. The novelty of this system stems from the adaptable control architecture designed to augment the pulsatile characteristics of the cardiovascular system.

  • Patent number: 10918651
    Abstract: The inventor has discovered that a particular dosage of Alpha Glycerylphosphoryl Choline administered to adult males results in a reduction of thyrotropin serum. Thytotropin levels are depressed with increased dopamine levels in the brain, and CDP-choline has been shown to increase dopamine and dopamine receptor density in the CNS. By suppressing the TSH levels in the brain to increase dopamine levels, this invention can assist in the treatment of depression, as well as symptoms of hyperthyroidism such as chills, depression, sluggishness, or feelings of weakness.
