  • Publication number: 20200174142
    Abstract: The present disclosure provides a system and method for efficiently mining multi-threshold measurements acquired using photon counting pixel-array detectors for spectral imaging and diffraction analyses. Images of X-ray intensity as a function of X-ray energy were recorded on a 6 megapixel X-ray photon counting array detector through linear fitting of the measured counts recorded as a function of counting threshold. An analytical model is disclosed for describing the probability density of detected voltage, utilizing fractional photon counting to account for edge/corner effects from voltage plumes that spread across multiple pixels. Three-parameter fits to the model were independently performed for each pixel in the array for X-ray scattering images acquired for 13.5 keV and 15.0 keV X-ray energies. From the established pixel responses, multi-threshold composite images produced from the sum of 13.5 keV and 15.

  • Patent number: 10609454
    Abstract: Assisted viewing of an indexed audio video stream is accomplished by enabling natural language command of an audio video stream repository to control the positioning of or selection within, manner of playback from, or other characteristic or action related to the viewed stream. Embodiments process spoken or textual commands, couched in ordinary natural language, which may include descriptive prose, or references to named persons or entities depicted in the stream. Both pre-recorded and live action audio video streams can be processed. Such processing can include creation anew or augmentation of an associated audio video stream index. Numerous particular useful commands, especially those pertinent to audio video streams of sports contests, are described. Embodiments may set alerts that are triggered by notable events within live action audio video streams, with notification of the user when they occur.

  • Patent number: 10416068
    Abstract: A quantitative optical microscopy arrangement is described. Specifically, a digital filter derived from linear discriminant analysis is described for recovering impulse responses in applications that may include photon counting from a high speed photodetector and applied to remove ringing distortions from impedance mismatch in multiphoton fluorescence microscopy. Training of the digital filter is achieved by defining temporally coincident and non-coincident transients and identifying the projection within filter-space that best separates the two classes. The training allows rapid data analysis by digital filtering. The LDA filter is also capable of recovering deconvolved impulses for single photon counting from highly distorted ringing waveforms from an impedance mismatched photomultiplier tube.

  • Patent number: 10410462
    Abstract: An exchangeable electric vehicle battery receptacle, kiosk is disclosed herein. The kiosk includes a receptacle, a bell crank and solenoid that lock a battery in the receptacle, and circuitry that dispenses the battery. The bell crank includes a first arm extending into the receptacle and a second arm coupled to an extension spring that is coupled to a fixed point on the kiosk. The battery includes a form factor dimensioned to fit at least partially around the first arm. The solenoid has an armature and is positioned adjacent to the second arm. The armature fixes the bell crank and fixes the extension spring in an extended state, thereby locking the battery in the receptacle slot. The circuitry retracts the armature into the solenoid. A retraction force on the second arm by the extension spring rotates the bell crank, at least partially dispensing the exchangeable battery from the receptacle slot.

  • Patent number: 10409047
    Abstract: A beam-scanning optical design is described for achieving up to kHz frame-rate optical imaging on multiple simultaneous data acquisition channels. In one embodiment, two fast-scan resonant mirrors direct the optical beam on a circuitous trajectory through the field of view, with the trajectory repeat-time given by the least common multiplier of the mirror periods. Dicing the raw time-domain data into sub-trajectories combined with model-based image reconstruction (MBIR) 3D in-painting algorithms allows for effective frame-rates much higher than the repeat time of the Lissajous trajectory. Because sub-trajectory and full-trajectory imaging are different methods of analyzing the same data, both high-frame rate images with relatively low resolution and low frame rate images with high resolution are simultaneously acquired.
