Publication number: 20200257346Abstract: A system and method for controlling a SSD in response to a power failure event of a main power supply to the SSD. The method includes receiving and storing write commands and associated data payloads for execution on the SSD in volatile memory, detecting the power failure event on the SSD, supplying backup power to the SSD during the power failure event, and executing one or more write commands stored in the volatile memory by storing the associated data payloads in a non-volatile memory on the SSD using the backup power. In response to the execution, removing the one or more write commands from the cache such that one or more unexecuted write commands and the associated data payloads remain in the cache, and storing a list of the one or more unexecuted write commands, but not the associated data payloads, in non-volatile memory using the backup power.Type: ApplicationFiled: February 13, 2019Publication date: August 13, 2020Inventors: Steven Wells, Robert Reed

Publication number: 20200217698Abstract: A magnetic flowmeter assembly for measuring the velocity of a conductive fluid in a flow path. The flowmeter assembly includes a coil driver for providing a drive current to a coil assembly, an electrode for measuring an electrical signal created by the conductive fluid flowing through a magnetic field created by the coil assembly, and a micro-processor for controlling the magnetic flowmeter. The micro-processor determines the electrical conductivity of the fluid based on the sensed electrical signal. The micro-processor then modifies the frequency of the coil driver in response to the fluid's electrical conductivity to optimize the sampling rate of the flowmeter. The flowmeter assembly modifies the coil driver frequency by either increasing the drive frequency for highly conductive fluids or decreasing the drive frequency for less conductive fluids.Type: ApplicationFiled: January 9, 2019Publication date: July 9, 2020Applicant: Georg Fischer Signet LLCInventors: Calin Ciobanu, Steven Wells
