Publication number: 20230375480Abstract: An image analysis system, a method and a point of care device are provided for determining, from an image of a cassette containing a sample, a concentration of one or more target analytes in the sample. The method includes identifying a region of interest (ROI) from the image corresponding to a result viewing area of the cassette, generating a unidimensional (1D) profile of the ROI, and probabilistically determining from the 1D profile, the concentration of the target analyte(s) in the sample based on a statistical model having one or more parameters of the 1D profile varying with respect to time and/or the concentration of the target analyte(s) in the sample.Type: ApplicationFiled: September 24, 2021Publication date: November 23, 2023Applicant: Siemens Healthcare Diagnostics Inc.Inventors: Siraj Issani, Simit Pradhan, Sudipa Bhattacharya, Manish Deshpande

Patent number: 10992176Abstract: A power harvesting system is provided for harvesting power from a current carrying conductor for powering a load. The power harvesting system includes an energy conversion module at least partially disposable on the current carrying conductor, and an impedance regulation module coupled to the energy conversion module. The energy conversion module couples an induced voltage proportional to a line current flowing in the current carrying conductor, for powering the load. The impedance regulation module dynamically regulates impedance in the power harvesting system for controlling transfer of the power harvested using the induced voltage and the line current, to the load.Type: GrantFiled: April 12, 2019Date of Patent: April 27, 2021Assignee: Siemens AktiengesellschaftInventors: Siraj Issani, Anand Venkatramani

Patent number: 10784807Abstract: A method and a parameter estimation system are provided for controlling an electrical machine, (e.g., an induction motor), powered by a drive unit. The method and the parameter estimation system disclosed herein detect a travelling wave generated on a linking element disposed between a first connection point, which is at least one terminal of the electrical machine, and a second connection point, which is at least one terminal of the drive unit. Further, the method and the parameter estimation system disclosed herein obtain at least one of a plurality of wave characteristics associated with the travelling wave, (e.g., an amplitude, a width, a frequency, a travel time of the travelling wave). Further, the method and the parameter estimation system disclosed herein determine one or more control parameters, (e.g., an operational torque and speed), of the electrical machine based on at least one of the wave characteristics.Type: GrantFiled: May 9, 2018Date of Patent: September 22, 2020Assignee: Siemens AktiengesellschaftInventors: Suryanarayana Bhamidipati, Siraj Issani, Anand Venkatramani

Patent number: 10298208Abstract: A dynamic impedance system deployable on a current transformer having a core and at least one winding element is provided. The dynamic impedance system includes a voltage reference module and a dynamic impedance module operably connected to one another. The voltage reference module defines a voltage threshold for regulating an output voltage of the current transformer. The dynamic impedance module regulates the output voltage based on the voltage threshold defined by the voltage reference module to maintain flux induced in the current transformer, thereby avoiding core saturation of the current transformer and enhancing accuracy of measurements.Type: GrantFiled: June 8, 2018Date of Patent: May 21, 2019Assignee: Siemens AktiengesellschaftInventors: Anand Venkatramani, Siraj Issani
