Patent number: 11841268Abstract: Aspects relate to a compact material analyzer including a light source, a detector, and a module including a first optical window on a first side of the module, a second optical window on a second side of the module opposite the first side, and a light modulator. The light source produces input light at a high power that is passed through the first optical window to the light modulator. The light modulator is configured to attenuate the input light, produce modulated light based on the input light, and direct the modulated light through the second optical window to the sample. The modulated light produced by the light modulator is at a lower power safe for the sample. The detector is configured to receive output light from the sample produced from interaction with the modulated light through the second optical window and to detect a spectrum of the output light.Type: GrantFiled: February 1, 2022Date of Patent: December 12, 2023Assignee: SI-WARE SYSTEMSInventors: Yasser M. Sabry, Bassem A. Mortada, Khaled Hassan, Abdelrahman Ahmed Maher Mohamed Elsayed Salem, Diaa Khalil, Mohamed H.

Publication number: 20230076993Abstract: Aspects relate to a handheld spectroscopy scanner including an optical window configured to receive a sample and a housing having the optical window thereon. The housing further includes therein a light source and a spectral sensor including a light modulator and a detector. The scanner housing further includes a processor configured to receive a spectrum of the sample from the spectral sensor based on interaction of light produced by the light source with the sample on the optical window. The processor is further configured to produce spectral data based on the sample spectrum for input to an artificial intelligence engine to produce a result based on the spectral data. In addition, the scanner housing may include a flange holding the light source and a heat sink configured to dissipate the internal heat generated. The housing further includes a cavity forming a handle for easy operation of the handheld spectroscopy scanner.Type: ApplicationFiled: September 6, 2022Publication date: March 9, 2023Inventors: Botros George Iskander Shenouda, Tarek Mohamed Zeinah, Bassem Mortada, Yasser M.

Publication number: 20230036551Abstract: Aspects relate to a spectral analyzer that can be used for biological sample detection. The spectral analyzer includes an optical window configured to receive a sample and a spectral sensor including a chassis having various component assembled thereon. Examples of components may include a light source, a light modulator, illumination and collection optical elements, a detector, and a processor. The spectral analyzer is configured to obtain spectral data representative of a spectrum of the sample using, for example, an artificial intelligence (AI) engine. The spectral analyzer further includes a thermal separator positioned between the light modulator and the light source.Type: ApplicationFiled: July 28, 2022Publication date: February 2, 2023Inventors: Yasser M. Sabry, Mohamed H. Al Haron, Bassem Mortada, Ahmed Othman, Diaa Khalil, Bassam Saadany, Ahmed Shebl, Botros George Iskander Shenouda

Patent number: 9013233Abstract: In a high-performance interface circuit for micro-electromechanical (MEMS) inertial sensors, an excitation signal (used to detect capacitance variation) is used to control the value of an actuation signal bit stream to allow the dynamic range of both actuation and detection paths to be maximized and to prevent folding of high frequency components of the actuation bit stream due to mixing with the excitation signal. In another aspect, the effects of coupling between actuation signals and detection signals may be overcome by performing a disable/reset of at least one of and preferably both of the detection circuitry and the MEMS detection electrodes during actuation signal transitions. In a still further aspect, to get a demodulated signal to have a low DC component, fine phase adjustment may be achieved by configuring filters within the sense and drive paths to have slightly different center frequencies and hence slightly different delays.Type: GrantFiled: September 13, 2011Date of Patent: April 21, 2015Assignee: Si-Ware SystemsInventors: Ahmed Elmallah, Ahmed Elshennawy, Ahmed Shaban, Botros George, Mostafa Elmala, Ayman Ismail, Mostafa Sakr, Ahmed Mokhtar, Ayman Elsayed
