Abstract: Systems, methods, and non-transitory computer readable media are configured to determine an optical length of an event in a cable. A physical length of the event in the cable can be determined based on a correlation between optical lengths and physical lengths in the cable. A geographic location of the event can be provided based on the physical length of the event.

Abstract: In example implementations, an integrated characterization vehicle is provided. The integrated characterization vehicle includes a memristor, a configuration cache and an analog measurement tile. The memristor has a driving unit to limit an amount of current that is driven through the memristor during testing. The configuration cache provides test parameters to control the testing of the memristor. The analog measurement tile provides a voltage to the memristor in accordance with the test parameters and to record a response of the memristor.

Abstract: A digital level shifter is disclosed that receives an input voltage from a first voltage domain, and provides an output voltage to a second voltage domain. The level shifter includes transistors configured in parallel with input transistors of the level shifter in order to place the output of the level shifter in a determinate state when one of the voltage domains is placed in a low power state. Further, the level shifter includes output transistors configured to equalize a rise time slew rate and fall time slew rate, improving the reliability of the level shifter as the voltage in each voltage domain varies.
