The methods enable direct extraction of proteins from microorganisms without the need for liquid protein extraction methods and yields positive identification results for gram-positive bacteria, gram-negative bacteria and yeast in minutes.

  • Patent number: 11169484
    Abstract: A cell visualization system includes a digital holographic microscopy (DHM) device, a training device, and a virtual staining device. The DHM device produces DHM images of cells and the virtual staining device colorizes the DHM images based on an algorithm generated by the training device using generative adversarial networks and unpaired training data. A computer-implemented method for producing a virtually stained DHM image includes acquiring an image conversion algorithm which was trained using the generative adversarial networks, receiving a DHM image with depictions of one or more cells and virtually staining the DHM image by processing the DHM image using the image conversion algorithm. The virtually stained DHM image includes digital colorization of the one or more cells to imitate the appearance of a corresponding actually stained cell.

  • Patent number: 11163048
    Abstract: Various sensors, sensor controllers, and sensor control methods are provided with model-based sideband balancing. In one illustrative embodiment, a controller for a piezoelectric transducer includes a transmitter, a receiver, and a processing circuit coupled to the transmitter and receiver. The processing circuit performs calibration and echo detection, the calibration including: sensing the piezoelectric transducer's phase response as a function of frequency; deriving equivalent circuit parameters for the piezoelectric transducer from the phase response; and determining a sideband imbalance based on one or more of the equivalent circuit parameters. Once the sideband imbalance is identified, the processing circuit may perform echo-detection processing that accounts for the sideband imbalance.

  • Patent number: 11160893
    Abstract: A method for controlling infections in a facility such as a hospital or foodservice establishment is provided. The method comprises tagging assets, monitoring asset location and pathogen contamination for each asset over time, analyzing data sets to identify which assets are the critical control points for pathogen transfer, and coating a residual self-sanitizing coating composition on each asset identified as a critical control point. The infection control method shuts down pathogen transfer routes by mitigating or eliminating pathogen growth on the critical control points.

  • Patent number: 11162852
    Abstract: A sensor to sense pressure in a pressure bottle and a method of assembling the sensor involve two or more fiber Bragg gratings (FBGs) affixed to a different radial location of a diaphragm seal of the pressure bottle. The sensor includes a light source to provide incident light to the two or more FBGs, and a photodetector to detect reflected light resulting from the two or more FBGs. Processing circuitry determines a pressure change in the pressure bottle based on the reflected light resulting from each of the two or more FBGs.

  • Patent number: 11149268
    Abstract: The present invention is based on the advantageous use of single-stranded oligonucleotides in the in vivo (within a cell) assembly of double-stranded oligonucleotides into a single double-stranded nucleic acid construct. The present invention relates to the use of at least a first and a second single-stranded oligonucleotide in the assembly within a cell of at least two double-stranded nucleic acid molecules into a single double-stranded nucleic acid construct of pre-determined sequence, wherein the first and second single-stranded oligonucleotide are essentially complementary to each other.

  • Patent number: 11105742
    Abstract: Disclosed are nucleated red blood cell warning devices and methods, and flow cytometers using the same. The devices, methods and flow cytometers can warn whether nucleated red blood cells exist in a blood sample. The warning device may obtain forward-scattered light information, side-scattered light information and fluorescence information when cells in the blood sample pass through a detection region of the flow cytometer. The warning device may generate a side-scattered light-fluorescence dot plot, so as to classify leucocytes into four groups, and may generate a forward-scattered light-fluorescence dot plot, where the forward-scattered light-fluorescence dot plot can include a leucocyte group region. The warning device may obtain a predetermined feature region located at the left side of the leucocyte group region, perform statistics on the amount of characterization cells in the predetermined feature region, and provide a warning when the number of the characterization cells exceeds a threshold value.

  • Patent number: 11083053
    Abstract: A process for heating articles in a heating system includes passing an article in a carrier through a heating chamber that is at least partially filled with a liquid medium to form a liquid bath. The process further includes heating the article in the carrier by at least partially submerging the article into the liquid bath during heating, the heating being performed, at least in part, using microwave energy. The process further includes one or more of adding fluid into and removing fluid from at least one location in the heating chamber to maintain a temperature profile across the heating chamber. In one implementation, the temperature of the liquid bath at an inlet area of the heating chamber is at least 10° C. cooler than a temperature of the liquid bath at an outlet area of the heating chamber.
