  • Patent number: 10564019
    Abstract: The invention is a gas flowmeter that produces precise flow measurements at low-flowrate ranges (for example, between 0.25 mL/min to 5,000 mL/min). It uses an infrared (“IR”) beam to detect the passing of a gas bubble through a liquid within a glass column. A “broken” beam is detected by the microcontroller for each passing of a bubble. This ability to allow the IR beam to be broken exactly at the passing of a bubble is made possible by the slit-over-slit design at the sides of the glass column and the column holder.

  • Patent number: 10488260
    Abstract: A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.

  • Patent number: 10451546
    Abstract: We present here systems and methods for generating a heterodyne signal using the naturally occurring chirp of a pulsed single-mode laser. The electrical square-wave pulse used to drive the laser heats the laser cavity, causing the laser frequency to change or chirp during the emission of the optical pulse. This chirped optical pulse can be split into a chirped signal pulse that interacts with a sample and a chirped reference pulse that interferes with the chirped signal pulse on a detector to produce a heterodyne modulation whose instantaneous phase and amplitude depend on the sample's dispersion and absorption, respectively. The chirp is reproducible, so the heterodyne modulation, instantaneous phase, and/or instantaneous amplitude can be average over many measurements, either with multiple pulses from the same laser or multiple pulses from different lasers, each emitting at a different wavelength.

  • Patent number: 10445880
    Abstract: Methods for label-free characterization of untagged molecules within a biological sample in-situ. The untagged molecules may be constituent of extracellular vesicles, and are excited in the biological sample with at least one wavelength band of light derived from a single stream of optical pulses. Light emitted by the untagged molecules by SHG, THG, 2PAF and 3PAF processes is detected. Separate measures of the biological sample corresponding to light emitted by the untagged molecules in each of the SHG, THG, 2PAF and 3PAF processes are derived. On that basis, normal extracellular vesicles may be differentiated from extracellular vesicles associated with a tumor on the basis of a specified signature of characteristics of images of SHG, THG, 2PAF and 3PAF processes.

  • Patent number: 10382684
    Abstract: An image capturing apparatus includes a sensor controller and a distance calculator. The sensor controller acquires a target image and a first reference image. The point spread function (PSF) of the target image is point-asymmetric, and the PSF of the first reference image being point-symmetric. The image sensor receives light having passed through a filter region that changes PSFs for sensor images of at least one kind into point-asymmetric forms, and then generates the target image for which a PSF has been changed into a point-asymmetric form by the filter region, and the first reference image that is not the target image. The distance calculator calculates the distance to an object captured in the target image and the first reference image, in accordance with the correlations each between an image obtained by convoluting a blur kernel to the target images and the first reference image.

  • Patent number: 10355446
    Abstract: A method for controlling an electromagnetic radiation source to produce single mode operation having an optimized side-mode suppression ratio over a set of wavelengths within a prescribed temporal profile. The electromagnetic radiation source is configured to output electromagnetic radiation at a given wavelength based upon parameters. The method includes determining a set of parameter combinations that satisfy a condition for a desired set of wavelengths and a minimum side mode suppression ratio over the range of wavelengths. The set of parameter combinations define sub-paths for nearly arbitrary transitions from one wavelength to another wavelength. Combinations of select sub-paths provide a multivariate path for transitioning over the range of wavelengths. The method also includes controlling the semiconductor laser to emit electromagnetic radiation over the range of wavelengths by traversing the multivariate path in a desired manner.
