    Abstract: Techniques are described for managing devices, such as Internet of Things (IoT) devices, using smart contract(s) on a distributed ledger (e.g., blockchain). Smart contract(s) executing on a distributed ledger may control access to one or more devices in a home or other environment. The smart contract(s) may employ information stored on the distributed ledger and information in a transaction sent to the smart contract(s) to determine whether particular user(s) and/or process(es) may access the device(s), issue commands to the device(s), access data generated by the device(s), and/or control the device(s). The smart contract(s) may provide a secure portal through which user(s) and/or service(s) may access device(s) for command and control of such device(s), and secure access may be based on permission information that is specified or provided by an owner or operator of the device(s) and that is stored on the distributed ledger.

    Abstract: A memory device includes at least one memory bank comprising a set of redundant word lines, a set of normal word lines, and row hammer refresh logic. The RHR logic comprises a first input to receive a first signal indicative of whether a match was generated at a fuse of the memory device, a second input to receive a redundant row address corresponding to a first location of a memory array of the memory device, a third input to receive a word line address corresponding to a second location of the memory array of the memory device. The RHR logic also comprises an output to transmit at least one first memory address adjacent to the first location or at least one second memory address adjacent to the second location based on a value of the first signal.

    Abstract: An electronic device may include an electronic display having a pixel and that displays an image based on compensated image data. The electronic device may also include image processing circuitry communicatively coupled to the electronic display. The image processing circuitry may receive image data and determine a gain value for the pixel based on an aging value of the pixel that is based on previously displayed pixel values of the pixel. The image processing circuitry may also adjust the gain value based on a pixel value of the image data corresponding to the pixel to generate an updated gain value and adjust the pixel value of the image data based on the updated gain value to generate, at least in part, the compensated image data.

    Abstract: Aspects herein relate to storing information concerning rights and liabilities or other records on distributed ledgers. A method disclosed can include identifying a transferor blockchain associated with rights and liabilities for transfer from a transferor to an acquirer, identifying an acquirer blockchain associated with the acquirer, creating an interim blockchain including the rights and liabilities, generating entries to the transferor blockchain removing the rights and liabilities, and generating entries to the acquirer blockchain adding the rights and liabilities. Another method disclosed can include identifying a critical record of a party, identifying a blockchain associated with the party, and generating an entry on the blockchain associated with the critical record, the entry having permissions related to at least the party.

    Abstract: Systems and devices are provided for tracking bandgap current generated by a bandgap circuit and mitigation of leakage current regardless of variations in PVT conditions. An apparatus may include one or more power amplifiers that powers components of the apparatus and comprising a transistor. The apparatus may also include bandgap current mirroring circuitry that generates a mirrored current that mirrors a received current that is process, voltage, and temperature (PVT) independent. The apparatus may also include a bulk voltage generator circuit including an amplifier having an input coupled to the bandgap current mirroring circuitry. Bulk voltage control circuitry is coupled to an output of the amplifier and generates a bulk voltage based on the relationship between the mirrored current and the leakage current.

    Abstract: Large sized electronic displays may include a backlight that generates light to illuminate a display panel. The backlight is divided into tiles that each includes a set of backlight elements that are driven by respective tile driver circuitry. Based on receiving brightness data and/or control signals from a backlight controller (BCON) of the backlight, the respective tile driver circuitry drives corresponding backlight elements such that the backlight elements suitably illuminate the display panel.
