Siva Hari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11409597
    Abstract: An error reporting system utilizes a parity checker to receive data results from execution of an original instruction and a parity bit for the data. A decoder receives an error correcting code (ECC) for data resulting from execution of a shadow instruction of the original instruction, and data error correction is initiated on the original instruction result on condition of a mismatch between the parity bit and the original instruction result, and the decoder asserting a correctable error in the original instruction result.

  • Publication number: 20220048525
    Abstract: Systems and methods for detecting hardware faults in computer-based feedback control systems. Multiple instances of the system control program(s) are run on system processors. System sensor data are input to each instance, and the control commands output by each instance are compared. As instantiations of the same programs receive largely the same sensor data, differences between output commands may indicate the presence of one or more hardware faults.

  • Patent number: 10817289
    Abstract: Software-only and software-hardware optimizations to reduce the overhead of intra-thread instruction duplication on a GPU or other instruction processor are disclosed. The optimizations trade off error containment for performance and include ISA extensions with limited hardware changes and area costs.

  • Patent number: 10621022
    Abstract: A family of software-hardware cooperative mechanisms to accelerate intra-thread duplication leverage the register file error detection hardware to implicitly check the data from duplicate instructions, avoiding the overheads of instruction checking and enforcing low-latency error detection with strict error containment guarantees.

  • Publication number: 20060106093
    Abstract: A formulation to deliver a full-spectrum of Vitamin E isomers for improved antioxidant capacity, bioavailability, dissolution and efficacy. The formulation includes dl-?-tocopheryl acetate or dl-?-tocopheryl succinate (synthetic Vitamin E), natural Vitamin E and mixed tocopherols, such as ?-, ?-, ?- and ?-tocopherol, as well as four isomers (?, ?, ? and ?) of tocotrienols. This formulation is designed to deliver at least 17-times the antioxidant capacity of synthetic Vitamin E (dl-?-tocopheryl acetate), and at least twice the antioxidant capacity of natural Vitamin E (d-?-tocopherol) as measured by oxygen radical absorbance capacity (ORAC) assay. The potent antioxidant capacity of this formula affords protection against oxidative damage of cell membranes, heart disease, cancer and eye and skin disease.
