  • Patent number: 10864471
    Abstract: The present invention provides a smart air filter blockage detection and alert communication system for use with filters in air circulation systems such as HVAC, vehicles, server systems, and dryers. The system attached to the frame of a filter comprises a light source, a light sensor, two actuators and a control unit. The control unit based on a stored program or an external command activates the actuators to place the source and the sensor devices attached to the two arms of the actuators on the two sides of the filter membrane. The sensor measures the light intensity transmitted through the filter. The control unit upon receiving the intensity data determines the filter blockage level and communicates alert to the user when the blockage exceeds a predetermined value. The system uses a 4G or a 5G IoT network capability for data collection and communication with servers and user devices.

    Abstract: The invention is a gas flowmeter that produces precise flow measurements at low-flowrate ranges (for example, between 0.25 mL/min to 5,000 mL/min). It uses an infrared (“IR”) beam to detect the passing of a gas bubble through a liquid within a glass column. A “broken” beam is detected by the microcontroller for each passing of a bubble. This ability to allow the IR beam to be broken exactly at the passing of a bubble is made possible by the slit-over-slit design at the sides of the glass column and the column holder.

  • Patent number: 10488260
    Abstract: A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.

  • Patent number: 10451546
    Abstract: We present here systems and methods for generating a heterodyne signal using the naturally occurring chirp of a pulsed single-mode laser. The electrical square-wave pulse used to drive the laser heats the laser cavity, causing the laser frequency to change or chirp during the emission of the optical pulse. This chirped optical pulse can be split into a chirped signal pulse that interacts with a sample and a chirped reference pulse that interferes with the chirped signal pulse on a detector to produce a heterodyne modulation whose instantaneous phase and amplitude depend on the sample's dispersion and absorption, respectively. The chirp is reproducible, so the heterodyne modulation, instantaneous phase, and/or instantaneous amplitude can be average over many measurements, either with multiple pulses from the same laser or multiple pulses from different lasers, each emitting at a different wavelength.

  • Patent number: 10175384
    Abstract: A probe is provided that contacts the inner surface of the casing or other production tubing and imparts energy to the surface at the contact point, for example as heat energy or mechanical energy. Energy is imparted around the circumference of the casing, and a fiber optic distributed sensor located on the outer surface of the casing is used to measure and record the energy that it receives while the probe is moved to impart energy around the circumference. A record of energy versus position of the probe around the circumference can be obtained, from which maxima in the detected energy measurements can then be found. The position around the circumference which gave the maximum measurement should be the position at which the optical fiber of the fiber optic distributed sensor is located. In addition, an ultrasonic arrangement is also described, that relies on ultrasonic sound to provide detection.

  • Patent number: 10134570
    Abstract: Methods, systems, and computer programs are presented for reducing chamber instability while processing a semiconductor substrate. One method includes an operation for identifying a first recipe with steps having an operating frequency equal to the nominal frequency of a radiofrequency (RF) power supply. Each step is analyzed with the nominal frequency, and the analysis determines if any step produces instability at the nominal frequency. The operating frequency is adjusted, for one or more of the steps, when the instability in the one or more steps exceeds a threshold. The adjustment acts to find an approximate minimum level of instability. A second recipe is constructed after the adjustment, such that at least one of the steps includes a respective operating frequency different from the nominal frequency. The second recipe is used to etch the one or more layers disposed over the substrate in the semiconductor processing chamber.

  • Patent number: 9970876
    Abstract: A dual source system and method includes a high power laser used to determine elements in a sample and a lower power device used to determine compounds present in the sample. An optical subsystem directs photons from a sample to a detector subsystem after laser energy from the laser strikes the sample along an optical path. After energy from the device strikes the sample protons are directed to the detector subsystem along the same optical path. The detector subsystem receives photons after laser energy from the laser strikes the sample and provides a first signal, and receives photons after energy from the device strikes the sample and provides a second signal. A controller subsystem pulses the high power laser and processes the first signal to determine elements present in the sample, energizes the lower power device and processes the second signal to determine compounds present in the sample.
