  • Publication number: 20190278890
    Abstract: The present disclosure provides for improving security in a meter or an intelligent electronic device (IED) through the use of a security key which is unique to each meter or IED. Such a key may be used to prevent password reuse among multiple meters. Such a key may also be used to encrypt critical components of the software, such that only when running on the correct meter can the components of the software be decrypted. Such a key may also be used to uniquely identify the device in a larger data collection and management system. The security key can also be used to prevent the direct copying of meters. The present disclosure also provides for a meter or IED that stores functional software separately from core software.

  • Patent number: 10402709
    Abstract: Devices, systems, and methods provide direct digitization and encoding of a parameter to be sensed or measured. Digitized readings are encoded into binary bits, which are acquired and handled by digital devices. An all-digital sensing device can be implemented in passive, active, or semi-passive forms, and in some embodiments includes a transducer, digitizer/encoder, reader, and transmitter. A transducer converts the parameter to be measured into a digitizable quantity, based on such as mechanical deformation, dielectric properties, or electromagnetic wave or acoustic-wave properties. A piezoelectric material transducer converts stress/pressure into resistance or voltage. A fiber-optic interferometer transducer converts pressure/temperature/PH into irradiation amplitude or wavelength shift in spectrum domain. Encoded binary or quasi-binary states are identified by a reader. Binary states have resolutions arranged according to a 2N format.
