Patent number: 11317834Abstract: An analyte sensor incorporates one or more techniques for discriminating between different optical signals. In one embodiment, the sensor includes a photodetector that detects a narrow band optical signal. In another embodiment, the sensor includes a multilayer filter including an absorption filter, a reflection filter, and a transparent layer between the absorption and reflection filters. In another embodiment, the sensor employs an indicator that emits light for a period of time after an excitation source is turned off. In another embodiment, the sensor employs a first indicator that is excited by an excitation light source and a second indicator that is excited by light emitted by the first indicator. The second indicator emits light for a period after the excitation source is turned off. In another embodiment, excitation light is polarized by a first polarizer, and a second polarizer at a photodetector passes only light polarized by the first polarizer.Type: GrantFiled: August 14, 2018Date of Patent: May 3, 2022Assignee: Senseonics, IncorporatedInventors: Bill Jenkins, Szymon Tankiewicz

Publication number: 20210177311Abstract: Apparatuses and methods for improving the accuracy of an analyte sensor are disclosed. The sensor may include a photodetector and a low angle sensitive (LAS) optical filter. The photodetector may be configured to convert received light into current indicative of the intensity of the received light. The LAS optical filter may be configured to prevent light having a wavelength outside a band pass region from reaching the photodetector and to pass light having a wavelength within the band pass region to the photodetector. The percentage of light passing through the LAS optical filter may decrease as the angle of incidence of the light increases.Type: ApplicationFiled: March 1, 2021Publication date: June 17, 2021Applicant: Senseonics, IncorporatedInventors: Joshua C.
