  • Patent number: 11000209
    Abstract: The present disclosure relates to methods and systems for estimating an efficiency of lungs of a patient receiving respiratory care. A blender has a primary input port for receiving a first gas to be delivered to the patient and one or more secondary input ports for receiving a second gas to be delivered to the patient from one or more gas sources. A patient-side port of the blender delivers the first and second gases to the patient. A gas composition sensor measures a fraction of the first gas and a gas flow sensor measures a flow of the first gas. A controller causes a sequential delivery of the first and second gases to the patient and estimates a functional residual capacity of the patient based on measurements from the gas composition sensor and from the gas flow sensor. The controller may also estimate a cardiac output of the patient.

  • Patent number: 10983218
    Abstract: Methods and systems for performing three-dimensional (3-D) LIDAR measurements with multiple illumination beams scanned over a 3-D environment are described herein. In one aspect, illumination light from each LIDAR measurement channel is emitted to the surrounding environment in a different direction by a beam scanning device. The beam scanning device also directs each amount of return measurement light onto a corresponding photodetector. In some embodiments, a beam scanning device includes a scanning mirror rotated in an oscillatory manner about an axis of rotation by an actuator in accordance with command signals generated by a master controller. In some embodiments, the light source and photodetector associated with each LIDAR measurement channel are moved in two dimensions relative to beam shaping optics employed to collimate light emitted from the light source. The relative motion causes the illumination beams to sweep over a range of the 3-D environment under measurement.

  • Patent number: 10353067
    Abstract: A multistatic array topology and image reconstruction process for fast 3D near field microwave imaging are presented. Together, the techniques allow for hardware efficient realization of an electrically large aperture and video-rate image reconstruction. The array topology samples the scene on a regular grid of phase centers, using a tiling of multistatic arrays. Following a multistatic-to-monostatic correction, the sampled data can then be processed with the well-known and highly efficient monostatic Fast Fourier Transform (FFT) imaging algorithm. In this work, the approach is described and validated experimentally with the formation of high quality microwave images. The scheme is more than two orders of magnitude more computationally efficient than the backprojection method. In fact, it is so efficient that a cluster of four commercial off-the-shelf (COTS) graphical processing units (GPUs) can render a 3D image of a human-sized scene in 0.048-0.101 seconds.

  • Patent number: 10261298
    Abstract: Disclosed are methods and devices for confocal microscopy in the near-infrared. wavelength. The device uses a near-infrared (NIR) light producing source such as laser; optical components designed to reflect and transmit NIR from a sample; and an NIR detector coupled to a computer for constructing a focal plane image from a raster scan. The detector may be a photodiode or photo-multiplier tube for detecting fluorescence signals in the NIR (800-1700 nm) wavelength range using a variety of NIR-I (800-1000 nm) and NIR-II (1000-1700 nm) dyes and nanomaterials. An imaging method is described using the NIR-confocal microscope for slice by slice 3D imaging of biological tissues throughout a thickness up to, for example, 5 mm in the NIR-II window. The reduced scattering in NIR-II allows for tissue penetration up to about 5-10 mm, superior to ˜0.2 mm afforded by conventional imaging.

  • Patent number: 10229486
    Abstract: A method automatically separates out the defect image from a thermogram sequence based on the physical characteristics of the defect of a conductive material in electromagnetic field. Defect area radiates more heat than other area, when it is mapped to the histogram of the image to be separated, the defect area is located in the top-end of histogram, and the proportion of defect area is smaller to the background or other area. The method equally divides the histogram of the image to be separated into multi groups, and calculates the first derivative ki of total pixel number Si of group i, finds the maximum absolute value of ki, i.e. |ki|max, where i is expressed as imax; if imax is the last group, Wn is regarded as threshold T, otherwise, Wimax+1 is selected as threshold T. The pixels that less than threshold T are removed to obtain the defect image in ECPT.

  • Patent number: 10041889
    Abstract: A system and method for the detection of foreign object debris materials or defects on and/or under a surface (e.g., outer ply) of a composite part being formed by a composite layup machine. A gantry moves over the composite part along a predetermined length thereof. A thermal excitation source fixed to the gantry directs infrared radiation across the width of the surface of the composite part. A infrared camera fixed to the gantry a predetermined distance away from the thermal excitation source scans the surface as the gantry moves to detect and output scan information thereof. A controller is coupled to the thermal excitation source and to the infrared camera. The controller processes the sequence of infrared images to identify a foreign object debris material or defect located on and/or under the surface.

  • Patent number: 9983056
    Abstract: An operating value of a first laser parameter of a laser device in a laser absorption spectrometer is optimized. The wavelength of laser device emitted light is adjusted by the first or a second laser parameter. The laser absorption spectrometer comprises a light intensity detector measuring the laser light intensity from the laser device. For each of multiple values of the first laser parameter: the light intensity detector measures light intensity obtained across a range of second laser parameter values, and an extremum in the light intensity measure and a peak position for the extremum are identified. A range of first laser parameter values is identified within the values of the first laser parameter for which there is a continuous trend in changes to the identified peak position with changes to the first laser parameter. The first laser parameter operating value is set to be within the identified range.

  • Patent number: 9977512
    Abstract: An optical proximity detector includes a driver, light detector, analog front-end, sensor(s) that sense correction factor(s) (e.g., temperature, supply voltage and/or forward voltage drop), and a digital back end. The driver drives the light source to emit light. The light detector produces a light detection signal indicative of a magnitude and a phase of a portion of the emitted light that reflects off an object and is incident on the light detector. The analog front-end receives the light detection signal and outputs a digital light detection signal, or digital in-phase and quadrature-phase signals, which are provided to the digital back-end. The digital back-end performs closed loop correction(s) for dynamic variation(s) in gain and/or phase caused by a portion of the analog front-end, uses polynomial equation(s) and sensed correction factor(s) to perform open loop correction(s) for dynamic variations in temperature, supply voltage and/or forward voltage drop, and outputs a distance value.
