Publication number: 20150330828Abstract: A fuel-gauge system detects the angular position of a float-based fluid-level-detecting mechanism's magnet and determines the level of liquid fuel remaining within a cylinder. The system wirelessly transmits to an app or application running on a multipurpose, consumer computing device fuel-remaining information, either in terms of percentage of maximum fluid level or, preferably, in terms of actual fluid volume remaining. The system determines fluid temperature and compensates for variation in the fluid-level attributable to temperature fluctuation.Type: ApplicationFiled: May 15, 2015Publication date: November 19, 2015Inventor: Arthur E. Colvin, JR.

Publication number: 20140088383Abstract: An implantable device with in vivo functionality, where the functionality of the device is negatively affected by ROS typically associated with inflammation reaction as well as chronic foreign body response as a result of tissue injury, is at least partially surrounded by a protective material, structure, and/or a coating that prevents damage to the device from any inflammation reactions. The protective material, structure, and/or coating is a biocompatible metal, preferably silver, platinum, palladium, gold, manganese, or alloys or oxides thereof that decomposes reactive oxygen species (ROS), such as hydrogen peroxide, and prevents ROS from oxidizing molecules on the surface of or within the device. The protective material, structure, and/or coating thereby prevents ROS from degrading the in vivo functionality of the implantable device.Type: ApplicationFiled: September 11, 2013Publication date: March 27, 2014Applicant: Senseonics, IncorporatedInventors: Arthur E.

Patent number: 8648356Abstract: A light emitting diode for harsh environments includes a substantially transparent substrate, a semiconductor layer deposited on a bottom surface of the substrate, several bonding pads, coupled to the semiconductor layer, formed on the bottom surface of the substrate, and a micro post, formed on each bonding pad, for electrically connecting the light emitting diode to a printed circuit board. An underfill layer may be provided between the bottom surface of the substrate and the top surface of the printed circuit board, to reduce water infiltration under the light emitting diode substrate. Additionally, a diffuser may be mounted to a top surface of the light emitting diode substrate to diffuse the light emitted through the top surface.Type: GrantFiled: April 8, 2013Date of Patent: February 11, 2014Assignee: Senseonics, IncorporatedInventors: Jason D.

Publication number: 20140018644Abstract: Methods, sensors, and systems for determining a concentration of glucose in a medium of a living animal are disclosed. Determining the glucose concentration may involve emitting excitation light from a light source to indicator molecules, generating a raw signal indicative of the amount of light received by a photodetector, purifying and normalizing the raw signal, and converting the normalized signal to a glucose concentration. The purification may involve removing noise (e.g., offset and/or distortion) from the raw signal. The purification and normalization may involve tracking the cumulative emission time that the light source has emitted the excitation light and tracking the implant time that has elapsed since the optical sensor was implanted. The purification and normalization may involve measuring the temperature of the sensor. The purification, normalization, and conversion may involve using parameters determined during manufacturing, in vitro testing, and/or in vivo testing.Type: ApplicationFiled: July 9, 2013Publication date: January 16, 2014Applicant: Senseonics, IncorporatedInventors: Arthur E.

Publication number: 20130324819Abstract: Apparatuses and methods for limiting the angle of incidence (AOI) of light reaching a dichroic filter. The apparatus may include an AOI filter element and the dichroic filter. The apparatus may be a sensor and may include a photodetector. The dichroic 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. Physical limitations of the dichroic filter may preclude the dichroic filter from preventing high AOI light having a wavelength outside a band pass region from reaching the photodetector. The AOI filter element may be configured to prevent light having a high AOI from reaching the dichroic band pass filter and to propagate light having a low AOI to the dichroic band pass filter. The AOI filter element may be a fiber optic bundle comprising a plurality of optical fibers.Type: ApplicationFiled: April 24, 2013Publication date: December 5, 2013Applicant: Senseonics, IncorporatedInventor: Arthur E.

Publication number: 20130241745Abstract: Systems and methods for automatically triggering wireless power and data exchange between an external reader and an implanted sensor. The implanted sensor may measure the strength of an electrodynamic field received wirelessly from the reader and convey field strength data based on the measured strength of the received electrodynamic field to the reader. If the field strength data indicates that the strength of an electrodynamic field received by the sensor is sufficient for the implanted sensor to perform an analyte measurement, the reader may convey an analyte measurement command to the sensor, which may execute the analyte measurement command and convey measurement information back to the reader. The systems and methods may trigger the analyte measurement as the reader transiently passes within sufficient range/proximity to the implant (or vice versa).Type: ApplicationFiled: October 11, 2012Publication date: September 19, 2013Applicant: Senseonics, IncorporatedInventors: Arthur E.

Patent number: 8233953Abstract: An optical-based sensor for detecting the presence or amount of an analyte using both indicator and reference channels. The sensor has a sensor body with a source of radiation embedded therein. Radiation emitted by the source interacts with indicator membrane indicator molecules proximate the surface of the body. At least one optical characteristic of these indicator molecules varies with analyte concentration. For example, the level of fluorescence of fluorescent indicator molecules or the amount of light absorbed by light-absorbing indicator molecules can vary as a function of analyte concentration. In addition, radiation emitted by the source also interacts with reference membrane indicator molecules proximate the surface of the body. Radiation (e.g., light) emitted or reflected by these indicator molecules enters and is internally reflected in the sensor body.Type: GrantFiled: October 26, 2007Date of Patent: July 31, 2012Assignee: Sensors for Medicine and ScienceInventor: Arthur E.

Publication number: 20110064617Abstract: An electro-optical sensing device for detecting the presence and concentration of an analyte in a liquid or gaseous medium includes a pair of indicator elements positioned to receive radiation from a radiation source and transmit radiation to a pair of photosensitive elements. The indicator elements each contain indicator molecules having an optical characteristic responsive to the presence of an analyte; however, one of the indicator elements is covered by an analyte-impermeable chamber that renders the indicator element insensitive to the presence of the analyte in the medium outside the chamber so that it can be used as a reference to cancel environmental and systemic variables that affect both indicator elements. The chamber preferably holds an analyte-containing fluid in contact with the reference indicator element so that the indicator elements operate under nominally identical conditions.Type: ApplicationFiled: November 23, 2010Publication date: March 17, 2011Applicant: Sensors for Medicine and Science, Inc.Inventors: Arthur E.

Publication number: 20100298674Abstract: An implantable device with in vivo functionality, where the functionality of the device is negatively affected by the inflammation reaction generally associated with tissue injury, encapsulated by a protective coating that prevents damage to the device from any inflammation reactions. The protective coating is designed to persist for a set period of time, generally until after the inflammation reaction of the surrounding in vivo environment in response to the injury caused by the implantation procedure has concluded. The protective coating is further designed to “resorb” (i.e. to dissociate from the device, dissolve, and be absorbed into the surrounding environment) after a set period of time, allowing the device to perform its in vivo functionality unhindered without loss of performance.Type: ApplicationFiled: April 21, 2010Publication date: November 25, 2010Applicant: Sensors for Medicine & Science, Inc.Inventors: Arthur E.
