  • Patent number: 11036267
    Abstract: In the event of a TDM failure, the associated computing device is either discarded or sent back to an original equipment manufacturer's facility for refurbishment. Field replacement of TDMs is typically not possible due to the lack of a secure process to recalibrate the touch controller to function properly with a replacement TDM. The presently disclosed systems and methods enable secure recalibration of a touch controller within a computing device to operate correctly with a new TDM field installed in the computing device. More specifically, the presently disclosed systems and methods provide a mechanism for detecting that a TDM has been field replaced, unlocking calibration data, performing a calibration process, and locking the new calibration data.

  • Patent number: 11010845
    Abstract: Improvements to IEC 61968-9:2013 meter reading schemas. These include significantly compressing messages into a single integer number which, when transmitted over a utility's communication system, is used to configure meters at utility user locations, obtain meter data, command and control operations at a utility location, and expand messaging capabilities. A method is disclosed for simplifying the IEC 61968-9:2013 schema for communications between a HeadEnd utility communications facility and the meter at an EndPoint so to enable use of the schema for operations it could not previously perform. While providing this enhanced capability, the IEC 61968-9:2013 schema's ability to function for its intended purpose; i.e., meter reading and control, is not compromised or impeded.
