Patent number: 11754482Abstract: This disclosure relates generally to a method and system for determining viscosity information of fluids. The present disclosure utilizes an intensity modulated continuous wave (CW) laser diode-based PA sensing method to obtain a continuous wave photoacoustic (CWPA) spectra. Through this CWPA spectra, a full width half maximum (FWHM) and a spectral area is determined to obtain the information about the viscosity of fluids. Although, the CWPA based sensing technique is used for distinguishing different types of abnormalities in tissues, so far it is not used for measuring viscosity which is an important thermo-physical property. The viscosity information of the fluids from the normalized Gaussian fitted CWPA spectra is based on a viscosity feature computed from a FWHM, and a spectral area. The viscosity feature improves the good of fit parameter (R2) significantly to 0.98 as compared to the traditional only FWHM based viscosity determination for which R2 is 0.91.Type: GrantFiled: November 22, 2021Date of Patent: September 12, 2023Assignee: Tata Consultancy Services LimitedInventors: Abhijeet Gorey, Arijit Sinharay, Chirabrata Bhaumik, Tapas Chakravarty, Arpan Pal

Patent number: 11754437Abstract: Disclosed are methods that, by not physically touching the material being measured, can measure the material's differential, response quite accurately. A collimated light shines on the material under test, is reflected off it, and is then captured by a recording device. The position where the reflected light is captured is used to calculate the deflection of the material. Dynamic characteristics of the material under test may be determined from the deflection measurement. The vibration frequency or vibration amplitude of a cantilever can be determined by repeated deflection measurements, all without physically touching the cantilever during the measurement process.Type: GrantFiled: September 30, 2019Date of Patent: September 12, 2023Assignee: UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: Benjamin C Masters, Rebekah C Wilson
