  • Publication number: 20240004749
    Abstract: Methods and apparatus for detecting a failed temperature sensor within a data storage device and for mitigating the loss of the sensor are provided. One such data storage device includes a non-volatile memory (NVM), a set of temperature sensors, and a processor coupled to the NVM and the temperature sensors. The processor is configured to detect failure of one of the temperature sensors and obtain temperature data from the other temperature sensors. The processor is further configured to estimate, based on the obtained temperature data, the temperature at the failed sensor, and then control at least one function of the data storage device based on the estimated temperature, such as controlling entry into a Read Only mode. In some examples, the processor estimates the temperature at the failed sensor or at various virtual sensor locations using pre-determined formulas having offsets and coefficients determined during an initial machine learning calibration procedure.

  • Publication number: 20190311886
    Abstract: Plasma source assemblies, gas distribution assemblies including the plasma source assembly and methods of generating plasma are described. The plasma source assemblies include a powered electrode with a ground electrode adjacent a first side, a first dielectric adjacent a second side of the powered electrode and at least one second dielectric adjacent the first dielectric on a side opposite the first dielectric. The sum of the thicknesses of the first dielectric and each of the second dielectrics is in the range of about 10 mm to about 17 mm.
