  • Patent number: 11915698
    Abstract: A system configured to improve track selection while performing audio type detection using sound source localization (SSL) data is provided. A device processes audio data representing sounds from multiple sound sources to determine SSL data that distinguishes between each of the sound sources. The system detects an acoustic event and performs SSL track selection to select the sound source that corresponds to the acoustic event based on input features. To improve SSL track selection, the system detects current conditions of the environment and determines adaptive weight values that vary based on the current conditions, such as a noise level of the environment, whether playback is detected, whether the device is located near one or more walls, etc. By adjusting the adaptive weight values, the system improves an accuracy of the SSL track selection by prioritizing the input features that are most predictive during the current conditions.

  • Patent number: 9696391
    Abstract: A precision high-speed shuttle device for transporting samples between different positions of a superconducting magnet with different magnetic field strength is provided. The sample equilibrated at the center of the magnet, where the magnetic field is the highest and homogeneous, is shuttled to a higher position above, where the fringe field is lower, for a defined period of time and shuttled back to the center for detection. By shuttling the sample to different positions in the magnet in different experiments one can obtain a field-dependent profile of particular physical parameters. The position and timing of the sample are precisely under the experimental controlled. In this way various magnetic field-dependent nuclear magnetic resonance (NMR) experiments can be conducted in a single high-field NMR spectrometer.

  • Patent number: 9285486
    Abstract: The invention relates to a method for radiation detection signal processing, and more particularly to a method capable of using a periodic signal to control the time of charging/discharging to a capacitor of an integrator. The method can be used for detecting the energy of incident photon of Gamma ray during the happening of an event while reducing dead time, and thereby, the count rate is increased. As the periodic signal is used as the signal for controlling the time of charging/discharging to a capacitor, the charging/discharging time of the integrator is no longer being controlled by the triggering time of the event, and thus, the present method is advantageous in that: the control method and circuit architecture are comparatively simpler since the charging/discharging time of the integrator no longer required to be controlled precisely, and thus the integration error due to insufficient resolution in delay element can be avoided.
