  • Publication number: 20210341392
    Abstract: Methods for laser induced ablation spectroscopy (LIBS) are disclosed. Light from laser ablation can be gathered into a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a broadband spectrometer operable to analyze a relatively wide spectral segment, and a different branch can convey a second portion of the light to a high dispersion spectrometer operable to measure minor concentrations and/or trace elements. Emissions can be analyzed using a plurality of spectrometers having distinct and/or complementary capabilities, and with a synergistic method using inductively coupled plasma mass spectrometry.

  • Patent number: 11081158
    Abstract: Methods, systems, and devices for a source follower-based sensing architecture and sensing scheme are described. In one example, a memory device may include a sense circuit that includes two source followers that are coupled to each other and to a sense amplifier. A method of operating the memory device may include transferring a digit line voltage to one of the source followers and transferring a reference voltage to the other source follower. After transferring the digit line voltage and the reference voltage, the source followers may be enabled so that signals representative of the digit line voltage and the reference voltage are transferred from the outputs of the source followers to the sense amplifier for sensing.
