  • Patent number: 11391667
    Abstract: A method of suppressing retroreflector fringe noise in TDL spectrometers (TDLS) that use a laser and retroreflector. The path between the laser and each retroreflector element is changed mechanically for example by using a movable support for the retroreflector. The phase of light reaching the retroreflectors is very sensitive to the pathlength. A pathlength change of a fraction of the light wavelength will significantly change the phase of the light. In this method the pathlength to each retroreflector is modulated by mechanical means and this modulation is both stronger and faster than atmospheric effects on phase. If mechanical modulation occurs at a sufficiently high frequency retroreflector fringe noise can be averaged by integration of the spectrometer output over a reading period of typically one second.

  • Patent number: 10661109
    Abstract: A method for detecting an event in or around a building. The method includes recording a baseline signal characteristic that characterizes a wireless signal transmitted between devices in or around the building during a baseline time period and recording a second signal characteristic that characterizes the wireless signal during a second time period after the baseline time period. An event in or around the building is detected in response to a determination that the second signal characteristic is abnormal relative to the baseline signal characteristic, the event degrading the wireless signal during the second time period. An alarm is triggered in response to detecting the event.

  • Patent number: 10641639
    Abstract: A liquid level sensing system provides a removable reservoir incorporating a reflective surface that can be interrogated by a stationary optical sensor in a receptacle receiving the removable reservoir. The optical sensor may detect the presence of the liquid within the reservoir without connection to the reservoir simplifying the process of making the reservoir removable while still allowing sensing of its contents. By aligning the optical axis with the insertion axis of the reservoir sensitive optical alignment problems are minimized.

  • Patent number: 10645378
    Abstract: A method and apparatus for characterizing a pixel of an image sensor is provided. The apparatus includes a narrowband, temporally incoherent, temporally stable illumination source. The narrowband light source generates a spatially coherent illumination beam. A variable optical attenuator attenuates the illumination beam resulting in an attenuated beam that does not alter the uniformity of the illumination. A focal plane integrator projects, expands, and homogenizes the attenuated beam to illuminate a focal plane of a sensor. Image sequences are collected to generate statistics for characterizing the sensor.

  • Patent number: 10571438
    Abstract: At least one baseline structural interrogation of a physical structure is performed in one or more corresponding baseline conditions of the structure. The one or more baseline conditions are stored, and one or more current conditions are sensed. It is determined whether a difference between the one or more current conditions and the one or more baseline conditions satisfies at least one threshold deviation criterion. A current structural interrogation of the structure is performed in response to determining that the difference between the one or more current conditions and the one or more baseline conditions satisfies the least one threshold deviation criterion. An indication that the at least one threshold deviation criterion is not satisfied is output in response to determining that that the difference between the one or more current conditions and the one or more baseline conditions does not satisfy the at least one threshold deviation criterion.

  • Patent number: 10495532
    Abstract: The optical fiber sensing method of the present invention includes steps of: joining heat shrinkable tubes to two ends of a sensing segment of an optical fiber; coupling a fixing element on the heat shrinkable tube below the sensing segment; detachably connecting at least one floating element to the fixing element; placing the floating element into a fluid; and providing an input signal to the sensing segment and generating an output signal after the input signal is processed by the sensing segment, wherein the tensile force applied to the sensing segment would change with variation of the buoyant force upon the floating element, resulting in change of the output signal. Accordingly, the optical fiber sensing method has numerous advantages, including rapid on-site construction, recyclability of components and changeability of design parameters.

  • Patent number: 10480975
    Abstract: The mass flow rate of milk flowing in a pipe in pulsed milk slugs is determined by sampling a signal from a microphone indicative of sonic signals produced by the milk flow. A microprocessor applies a Fast Fourier Transform to the sampled signal to produce the frequency domain of the sampled signal. The microprocessor computes the average energy value of the sampled signal in a relevant frequency band during consecutive monitoring periods. The average energy values are inserted into a calibration equation to convert the average energy value to a mass flow rate. The total mass flow of milk flowing through the pipeline during a period T1-T2 is determined by integrating the determined mass flow rate of milk from T1-T2. Disengagement of a milking cluster from the animal teats during milking is determined when the monitored microphone signal transitions to a continuous relatively high energy noise signal indicative of air.
