  • Determining redundancy in transformed sensor data
    Patent number: 10701363
    Abstract: Two or more video signals are received at respective two or more peer-level storage nodes. Discrete wavelet transformations are performed on the two or more video signals via the two or more peer-level storage nodes. Temporally stationary background data is determined from the discrete wavelet transformations at each of the two or more peer-level storage nodes. Redundancies are determined using the temporally stationary background data, the redundancies indicating an overlap between the two or more video signals. A storage size of two or more video signals is reduced by not storing the redundancies on at least one of the peer-level storage nodes.

  • Mitigation of error correction failure due to trapping sets
    Patent number: 10666295
    Abstract: An apparatus includes an interface and a control circuit. The interface may be configured to process transfers to/from a medium. The control circuit may be configured to generate a trapping set list of trapping sets of a low-density parity check code, classify bit positions of the trapping sets as belonging to either a user bits field or a parity bits field of a codeword, encode data using the low-density parity check code to generate the codeword, and present the codeword to the interface to transfer the codeword to the medium. The generation of the codeword may include at least one of a shortening or a puncturing of bit locations in the codeword in response to the classifying of the bit positions of the trapping sets. All of the data may be held in the bit locations of the codeword other than the bit locations that are shortened or punctured.
