  • SAFETY VERIFICATION FOR PROGRAMMABLE LOGIC DEVICES, AND RELATED METHODS, APPARATUSES, AND SYSTEMS
    Publication number: 20250208595
    Abstract: An apparatus comprises a programmable logic device including programmable logic elements. The programmable logic elements are configurable to implement functions according to configuration data stored in non-volatile memory cells of the programmable logic elements. The programmable logic device to store a digest value in memory, the digest value at least partially based on the configuration data stored in the non-volatile memory cells. The programmable logic service is also to perform an integrity check to verify whether a currently computed digest value matches the digest value, the currently computed digest value at least partially based on current configuration data stored in the non-volatile memory cells; read the digest value; determine a check value at least partially based on the digest value; and provide the check value at an output of the programmable logic device. The check value may be provided at the output for verification at a verification circuit.

  • Devices for detecting the presence of a source of power
    Patent number: 7129822
    Abstract: An apparatus is provided that includes an uninterruptible power supply (UPS) configured to be connected to a power distribution network. A communications circuit is also provided. The communications circuit is operatively associated with the UPS and operative to generate a power line carrier status signal on the power distribution network. The power line carrier status signal is indicative of a status of power delivered to the power distribution network by the UPS. Related methods of operating such apparatus are also provided.
