  • Patent number: 11978506
    Abstract: This document describes a spatial light modulator that comprises a pixel array having a plurality of pixels whereby each pixel in this array is communicatively coupled to a digital pixel circuit which are in turn all coupled to a bit-plane control circuit. The bit-plane control circuit is configured to generate, using a Pulse Code Modulation (PCM) algorithm, bit-plane signals that are used to control the sample and hold functions performed by each of the digital pixel circuits so that the pixel array may carry out its scanning function accurately and in a power efficient manner.

  • Patent number: 11948144
    Abstract: Systems and methods for recovery access to lost blockchain wallet seed phrases are disclosed. The systems and methods can store seed phrases for users for future retrieval. In some examples, a decentralized oracle creates an oracle private key that can be used to authenticate a user who is requesting the seed phrase. In some examples, the oracle creates a private/public key pair that can be used to transmit and store an encrypted version of the seed phrase. The authentication steps described herein also include knowledge-based authentication questions about the wallet, e.g., prior transactions using the wallet, value of the wallet, and the like.

  • Publication number: 20240104599
    Abstract: A system may verify a plurality of electronic utility data records to determine when each of the plurality of electronic utility data records is authentic. The system may determine a proportion of sustainable energy utilization data in each of the verified plurality of electronic utility data records. The system may assign a weighting factor to the determined proportion of the sustainable energy utilization data for each the verified plurality of electronic utility data records. The system may generate a sustainable energy score from the assigned weighting factor for each of the verified plurality of electronic utility data records. The system may rank each of the verified plurality of electronic utility data records by the generated sustainable energy score. The system may determine one or more of the ranked plurality of electronic utility data records above a predefined threshold level, and may provide incentives to computing device(s) associated with such records.
