Patent number: 11953377Abstract: Aspects relate to an integrated and compact attenuated total internal reflection (ATR) spectral sensing device. The spectral sensing device includes a substrate, a spectrometer, and a detector. The substrate includes an ATR element, a microfluidic channel, and a channel interface at a boundary between the ATR element and the microfluidic channel formed therein. The ATR element is configured to receive input light and to direct the input light to the channel interface for total internal reflection of the input light at the channel interface. An evanescent wave produced by a sample contained within the microfluidic channel based on the total internal reflection of the input light attenuates the light output from the ATR element and the resulting output light may be analyzed using the spectrometer and the detector.Type: GrantFiled: February 15, 2022Date of Patent: April 9, 2024Assignee: SI-WARE SYSTEMSInventors: Yasser M. Sabry, Amr O. Ghoname, Momen Anwar, Diaa Khalil

Publication number: 20230014558Abstract: Aspects relate to a compact and low-cost gas analyzer that can be used for different types of gas analysis, such as air quality analysis. The gas analyzer can include a light source, a gas cell configured to receive a sample (e.g., a gas under test), a spectral sensor including a spectrometer and a detector, and an artificial intelligence (AI) engine. Light can enter the gas cell and interact with the sample to produce output light that may be measured by the spectral sensor. The resulting spectrum produced by the spectral sensor may be analyzed by the AI engine to produce a result. The gas analyzer further includes a self-calibration component configured to enable calibration of the sample spectrum to compensate for spectral drift of the spectral sensor.Type: ApplicationFiled: July 5, 2022Publication date: January 19, 2023Inventors: Yasser M.
