Patent number: 10267743Abstract: Color quantification of chemical test pads and titration of analytes can be performed under different lighting conditions. In one embodiment, the lighting condition is estimated under which a digital image is captured and utilized to select a set of reference colors from which the quantified color is compared to determine the titration. In another embodiment, a plurality of comparisons are made with different lighting conditions with the result having the highest confidence level being selected to determine the titration.Type: GrantFiled: February 29, 2016Date of Patent: April 23, 2019Assignee: Scanadu IncorporatedInventors: Bernard Burg, Martin Zizi, Aaron Alexander Rowe, Anthony Smart, Walter De Brouwer

Patent number: 9863811Abstract: In one embodiment, a diagnostic system for biological samples is disclosed. The diagnostic system includes a diagnostic instrument, and a portable electronic device. The diagnostic instrument has a reference color bar and a plurality of chemical test pads to receive a biological sample. The portable electronic device includes a digital camera to capture a digital image of the diagnostic instrument in uncontrolled lightning environments, a sensor to capture illuminance of a surface of the diagnostic instrument, a processor coupled to the digital camera and sensor to receive the digital image and the illuminance, and a storage device coupled to the processor. The storage device stores instructions for execution by the processor to process the digital image and the illuminance, to normalize colors of the plurality of chemical test pads and determine diagnostic test results in response to quantification of color changes in the chemical test pads.Type: GrantFiled: August 15, 2015Date of Patent: January 9, 2018Assignee: SCANADU INCORPORATEDInventor: Bernard Burg

Patent number: 9690904Abstract: In accordance with one embodiment, a method for a health scanning system is disclosed. The method includes receiving at least one electrical physiological data signal (PDS); suppressing a Direct Current (DC) signal component of the PDS to emphasize the Alternating Current (AC) signal component of the PDS; isolating the signal noise in the AC signal component of the PDS; and extracting a noise signature from the signal noise in the PDS. The noise signature, after calibration, can be used to uniquely identify a known user from other users.Type: GrantFiled: February 2, 2015Date of Patent: June 27, 2017Assignee: Scanadu IncorporatedInventor: Martin Zizi

Patent number: 9607380Abstract: Methods and electronic devices for performing color-based reaction testing of biological materials. The method includes capturing and interpreting digital images of an unexposed and later exposed paddle at various delay times within an automatically calibrated environment. The test paddle includes a unique identification mechanism (UID), a Reference Color Bar (RCB) providing samples of standardized colors for image color calibration, compensation and corrections, and several test-specific sequences of Chemical Test Pads (CTP). The method further includes locating the paddle in the image, extracting the UID and validating the paddle, extracting the RCB and locating the plurality of CTP in each image. The method further reduces image noise in the CTP and calibrates the image automatically according to lighting measurements performed on the RCB.Type: GrantFiled: March 26, 2016Date of Patent: March 28, 2017Assignee: Scanadu IncorporatedInventors: Bernard Burg, Martin Zizi, Aaron Alexander Rowe, Anthony Smart, Walter De Brouwer

Patent number: 9528941Abstract: In one embodiment, an apparatus for automatic test diagnosis of a test paddle is disclosed. The apparatus comprises a personal computing device including: a camera to capture images over time of test pads of a test paddle, a processor coupled to the camera, and a display device coupled to the processor. The processor analyzes the color changes over time of each test pad to determine a color trajectory over time for each test pad. The processor compares the color evolution trajectory for each test pad with color calibration curves for each test pad to determine an analyte concentration of a test biological sample, such as urine. During the analysis by the processor, the display device displays a user interface with results of the analyte concentration in response to the analysis over time.Type: GrantFiled: March 5, 2015Date of Patent: December 27, 2016Assignee: SCANADU INCORPORATEDInventors: Bernard Burg, Martin Zizi, Walter De Brouwer, Anthony Smart
