  • Patent number: 11971309
    Abstract: A system includes an antenna having a predetermined directivity and a measurement data processing device that modifies spatial resolution of measurement data received from the antenna. The device includes a plurality of multipliers that multiply together measurement values, which are the signal intensity of the microwave output by the microwave radiometer, and weighting coefficients to be an element of a weighted vector a and output multiplication results; and an integrator that integrates the multiplication results of the plurality of multipliers. The weighted vector a modifies the accuracy of the corrected sensitivity function ?(x,y) with performance of the arithmetic processing of the inverse problem in order to reduce integrated values of a positive value region and a negative value region present on an outer side of the sensitivity distribution of the target antenna sensitivity distribution function F(x,y) in the corrected sensitivity function ?(x,y).

  • Patent number: 11633172
    Abstract: An ultrasound imaging system which uses multiline receive beamforming for synthetic transmit focusing are phase adjusted to account for speed of sound variation in the transmission medium. The phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the frequency domain for both the transmit angular spectrum and the receive angular spectrum. The phase variation is removed in the frequency domain, then an inverse Fourier transform is used to transform the frequency domain results to the spatial domain. In another implementation, the phase discrepancy of the received multilines is estimated and corrected entirely in the spatial domain.

  • Patent number: 11614367
    Abstract: Apparatus and methods are disclosed utilizing selected infrared waveband observations to determine selected profiles of interest. A correlative system is constructed and installed at a processor. Thermal and refractivity profiles and structure in a waveband of interest are extracted from observed infrared spectrum single waveband observations received for processing at the processor by the correlative system. The output provides the selected profiles of interest in the waveband of interest. The apparatus includes an infrared receiver and means for measuring angular displacement of received emissions relative to a horizon. The processor converts received emission into equivalent Planck blackbody temperatures across the observations and correlates structure and vertical distribution of the temperatures to provide thermodynamic and refractivity profiles of interest.

  • Patent number: 11586152
    Abstract: An ensemble of spin defect centers or other atom-like quantum systems in a solid-state host can be used as a compact alternative for an atomic clock thanks to an architecture that overcomes magnetic and temperature-induced systematics. A polariton-stabilized solid-state spin clock hybridizes a microwave resonator with a magnetic-field-insensitive spin transition within the ground state of a spin defect center (e.g., a nitrogen vacancy center in diamond). Detailed numerical and analytical modeling of this polariton-stabilized solid-state spin clock indicates a potential fractional frequency instability below 10?13 over a 1-second measurement time, assuming present-day experimental parameters. This stability is a significant improvement over the state-of-the-art in miniaturized atomic vapor clocks.

  • Patent number: 11441951
    Abstract: Apparatus and methods are disclosed for highly accurate remote measurement of sea surface skin temperature. Thermal band 8 to 14 micron images of the surface of the ocean taken by a downward looking infrared camera are processed to determine the optimum segments of the image to utilize. The influence of contaminating reflection of the downwelling flux from the sky and other error sources are removed and from the data and/or otherwise corrected for making sea surface temperature accuracy within several tenths of a degree possible.

  • Patent number: 10791283
    Abstract: An imaging device for imaging of a local area surrounding the imaging device. The imaging device includes a lens assembly, a filtering element and a detector. The lens assembly is configured to receive light from a local area surrounding the imaging device and to direct at least a portion of the received light to the detector. The filtering element is placed in the imaging device within the lens assembly such that light is incident at a surface of the filtering element within a range of angles determined by a design range of angles at which the filtering element is designed to filter light. The detector is configured to capture image(s) of the local area including the filtered light. The imaging device can be integrated into a depth camera assembly for determining depth information of object(s) in the local area based on the captured image(s).

  • Publication number: 20090147821
    Abstract: A method and device are described for controlling and/or attenuating aiming laser beam brightness in a hand held radiometer. The beam from the laser is directed at a target measurement surface and a transversely movable element member is interposed between the laser and the target to change the beam brightness on the target. In a preferred device a slidable or rotatable element intercepts the beam between the laser and target and a calibrated opening in the element of selected size and/or shape allows part of the beam to pass through the element to provide a safe brightness at the target.
