Patent number: 11723564Abstract: A compact optical sensor is used to determine heart rate, hemoglobin, hydration, peptides, or oxygen saturation using a light source and a single photodiode. The single photodiode has a first filter and a second filter. The first filter is closer to the light source and is transparent to green light and blocks red light. The second filter is farther from the light source and is transparent to red light and blocks green light. This arrangement of the filters facilitates acquisition of backscattered light from desired depths of measurement within the body of a user. At a first time, the light source emits red light and first output from the photodiode is determined. At a second time, the light source emits green light and second output from the photodiode is determined. The optical sensor determines oxygen saturation using the first output and heart rate using the second output.Type: GrantFiled: February 1, 2021Date of Patent: August 15, 2023Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Miro Yakov Shverdin, Nevzat Akin Kestelli

Patent number: 11717234Abstract: A decision support tool is provided for predicting the neonatal vitality scores of a fetus during delivery, the scores being an indicator of future health for the infant anticipated to be born within a future time interval, measured as time to birth. The predicted neonatal vitality score is determined from measurements of physiological variables monitored during labor, such as uterine activity and fetal heart rate. Fetal heart rate variability and patterns may be detected and computed using the monitored physiological variables, and neonatal vitality scores may be predicted based, at least in part, on the variability metrics and fetal heart rate patterns. Scores may be predicted for different delivery methods, such as vaginal delivery or cesarean delivery, for different time-to-birth intervals. In this way, these scores may be used for decision support for care plans during labor, such as increased monitoring and/or modifying the delivery type.Type: GrantFiled: June 16, 2021Date of Patent: August 8, 2023Assignee: Cerner Innovation, Inc.Inventors: Andrew Roberts, Sasanka Are, Jeffrey W.

Patent number: 11701035Abstract: The blood glucose (BG) detector (BGD) stores baseline BG data therein. The BGD has a housing with legs forming a U-shaped sensing channel for a finger web or ear antihelix. The sensory channel limits insertion of the web/antihelix. A positional light sensor subsystem audibly and/or visually indicates a test-to-test detection position. A BG sensor on the legs uses IR 1550 bandwidth light to detect BG by transmission through the web/antihelix ro generate a detected BG signal. A comparator (in processor-memory system) compares detected BG signal to baseline BG data and generates a displayable BG level to the user via a display module. Alternatively, a leg-to-leg distance sensor may be used. A keypad enables upload of the BD baseline data (or an I/O port).Type: GrantFiled: October 28, 2019Date of Patent: July 18, 2023Inventor: Bruce M. Landy
