  • Patent number: 10240966
    Abstract: A fluid level detecting system provides an input signal at a specific frequency to a sample in a container. A probe contacts the energized sample and provides a signal to a level sensing circuit. The level sensing circuit amplifies the signal from the probe and then bandpass filters, tuned to the specific frequency, the amplified signal. This filters out extraneous signals received from, for example, a cover on the container, and specifically identifies when the probe has contacted the sample fluid by comparing the filtered signal to threshold levels.

  • Patent number: 10209337
    Abstract: In a method and apparatus for acquiring magnetic resonance (MR) raw data, an MR data acquisition scanner is operated to execute a turbo spin echo (TSE) or a turbo gradient spin echo (TGSE) sequence wherein nuclear spins are excited in multiple slices of the examination object simultaneously by radiating at least one radio-frequency (RF) pulse from an RF radiator of the MR data acquisition scanner, thereby causing the excited nuclear spins in said multiple slices to produce an echo train. A multi-band refocusing pulse is radiated that refocuses nuclear spins in at least one of said multiple slices that follows a first of the multiple slices, and readout gradients are activated to acquire MR signals, with respectively different contrasts, at respectively different readout times of the echo train. The read out MR signals are entered into an electronic memory organized as k-space.

  • Patent number: 10187003
    Abstract: A system obtains respective measurements of relevant electrical parameters of a motor during operational stages including a start-up stage, a transition stage, a steady-state stage, idle stage, or a shutdown stage of the motor driven system driven by the motor. Based on the respective measurements, the monitoring system then determines respective electrical patterns corresponding to the operational stages. Next, the monitoring system compares the respective electrical patterns corresponding to the operational stages with respective baseline electrical patterns modeled for the operational stages to yield a comparison. Then, the monitoring system determines a status of the motor driven system based on a comparison between baseline and observed operating parameters. Trend pattern monitoring is used to eliminate storing massive volumes of trend data by capturing and characterizing the important moments when data values change in a significant manner.
