  • Patent number: 10806374
    Abstract: A wearable system and method for providing BCG data from a user including a wearable sensor configured to receive cardiogenic surface vibration waveforms, a calibrating sensor configured to receive cardiogenic center-of-mass (COM) vibration waveforms, and a processor configured to use the COM vibration waveforms as a template for modifying the surface vibration waveforms to provide health-related outputs. A systematic approach for elucidating the relationship between surface vibrations of the body in the head-to-foot direction from the wearable sensor, and the movements of the whole body as measured by the calibrating sensor is disclosed. Additionally, a methodology for converting the wearable acceleration signals to BCG signals such that the same analysis and interpretation tools can be used for both measurements is presented.

  • Patent number: 10796190
    Abstract: A sensor may measure light reflecting from a multi-layered object at different times. A digital time-domain signal may encode the measurements. Peaks in the signal may be identified. Each identified peak may correspond to a layer in the object. For each identified peak, a short time window may be selected, such that the time window includes a time at which the identified peak occurs. A discrete Fourier transform of that window of the signal may be computed. A frequency frame may be computed for each frequency in a set of frequencies in the transform. Kurtosis for each frequency frame may be computed. A set of high kurtosis frequency frames may be averaged, on a pixel-by-pixel basis, to produce a frequency image. Text characters that are printed on a layer of the object may be recognized in the frequency image, even though the layer is occluded.

  • Patent number: 10787703
    Abstract: Genomic DNA contains embedded ribonucleotides (rNMPs) that are incorporated during DNA replication and repair, or formed during DNA damage. The modifications have been linked to genome instability and disease, but no method currently exists to profile their locations genome-wide. rNMP incorporation has been extensively studied in recent years; however, locating sites of rNMP incorporation in genomic DNA has not yet been possible. Disclosed herein is a unique method for mapping rNMPs in genomic DNA that exploits the unique ligation mechanism of Arabidopsis thaliana tRNA ligase (AtRNL), normally involved in tRNA maturation. As disclosed herein AtRNL captures 2?,3?-cyclic phosphate or 2?-phosphate termini of DNA derived from alkaline cleavage of a DNA oligonucleotide (oligo) at an embedded rNMP, ligating the 2?-phosphate end to the 5?-phosphate terminus of the same DNA molecule and producing a ssDNA circle containing an embedded rNMP.

  • Publication number: 20200269322
    Abstract: Scanning Laser Epitaxy (SLE) is a layer-by-layer additive manufacturing process that allows for the fabrication of three-dimensional objects with specified microstructure through the controlled melting and re-solidification of a metal powders placed atop a base substrate. SLE can be used to repair single crystal (SX) turbine airfoils, for example, as well as the manufacture functionally graded turbine components. The SLE process is capable of creating equiaxed, directionally solidified, and SX structures. Real-time feedback control schemes based upon an offline model can be used both to create specified defect free microstructures and to improve the repeatability of the process. Control schemes can be used based upon temperature data feedback provided at high frame rate by a thermal imaging camera as well as a melt-pool viewing video microscope. A real-time control scheme can deliver the capability of creating engine ready net shape turbine components from raw powder material.
