  • Patent number: 10718660
    Abstract: A system and method for verifying a connection between a first and second connector. The system includes a transducer and a processor. The processor is configured to determine a velocity of the first connector when the first connector is moved to the second connector to form a coupling, calculate a time interval to the coupling based on the velocity detected at the set point and a position of the second connector, and receive, from the transducer, a signal during the time interval. The signal includes the sound generated when the coupling is formed. The processor analyzes the signal and identifies the sound of the coupling within the signal. The signal is filtered in the frequency domain and in the time domain, resulting in a filtered spectrogram. The spectrogram is compared to a pattern. The processor determines if the first and second connector are properly coupled based on the comparison.

    Abstract: This disclosure is directed to fiber optic pulsed polarimeters based on either streak camera or photodiode detection using a backscatter tailored optical fiber and the polarization optical time domain reflectometry technique for conducting remote diagnostic measurements of inducing fields along the fiber. The backscatter tailored optical fiber comprises a single mode fiber with an array of fiber Bragg gratings written to produce a predetermined distribution of backscatter signal in intensity and spectral content in response to a pulse propagating along the array. The fiber optic pulsed polarimeter includes a directional coupler that diverts the backscatter from the backscatter-tailored optical fiber to a polarization detection system for determining the polarization state of the backscatter as the polarized light pulse transits the backscatter-tailored optical fiber.

  • Patent number: 10386300
    Abstract: Methods are provided to identify spatially and spectrally multiplexed probes in a biological environment. Such probes are identified by the ordering and color of fluorophores of the probes. The devices and methods provided facilitate determination of the locations and colors of such fluorophores, such that a probe can be identified. In some embodiments, probes are identified by applying light from a target environment to a spatial light modulator that can be used to control the direction and magnitude of chromatic dispersion of the detected light; multiple images of the target, corresponding to multiple different spatial light modulator settings, can be deconvolved and used to determine the colors and locations of fluorophores. In some embodiments, light from a region of the target can be simultaneously imaged spatially and spectrally. Correlations between the spatial and spectral images over time can be used to determine the color of fluorophores in the target.

Operation of the dispensing device may be enabled based upon the refill material being the valid refill material. If the refill material comprises the invalid refill material, then operation of the dispensing device may be disabled and/or a flush option (e.g., evacuating the invalid refill material from the dispensing device) may be activated.
