Patent number: 11666253Abstract: Continuous glucose monitoring (CGM) may include applying a periodic excitation signal via an electrode of a CGM sensor to human interstitial fluid to drive an oxidation/reduction reaction, and measuring the current through the electrode. In some embodiments, the measured current is sampled and digitized, and various harmonics of the excitation signal's fundamental frequency are extracted. A set of relationships of at least two harmonics each is generated from the spectral amplitudes of a set of pairs, triplets, etc., of the harmonics, and the set of relationships is mapped to a glucose concentration such as based on the contents of a harmonic relationship database having a pre-existing set of harmonic relationships and glucose concentrations to which those sets of harmonic relationships correspond, for example. Numerous other embodiments are provided.Type: GrantFiled: February 20, 2020Date of Patent: June 6, 2023Assignee: Ascensia Diabetes Care Holdings AGInventors: Juergen J. Zach, Daniel V. Brown

Publication number: 20180348193Abstract: Systems and methods employ a test sensor that includes an identification feature, such as a resistive element or other detectable circuit element, which allows a measurement device to interrogate the test sensor and to determine whether the correct test sensor type is being used to collect a fluid sample. For example, some embodiments employ test sensors that a measurement device can identify according to a response received from the test sensors when the measurement device applies an electrical signal to the test sensors. By facilitating identification of a test sensor, embodiments help ensure that the desired test type, calibration codes, and/or assay sequence are applied to the fluid sample collected by the test sensor.Type: ApplicationFiled: August 17, 2015Publication date: December 6, 2018Inventors: Daniel V.

Patent number: 7945394Abstract: A method of detecting incomplete filling of an electrochemical biosensor by collecting a series of electrical current values when a constant electrical potential is applied across the working and counter electrodes during a preliminary burn period. The slope of a line determined by linear regression based on the series of current values is used to determine whether or not the biosensor is incompletely filled. If the line has a positive slope, the biosensor is reported to be under filled. If the slope is not positive, the correlation coefficient of the current values is used as a supplemental test to indicate whether or not the biosensor is incompletely filled.Type: GrantFiled: June 16, 2005Date of Patent: May 17, 2011Assignee: Bayer Healthcare LLCInventors: Daniel V.

Patent number: 7367424Abstract: A muffler system is provided for use with an auxiliary power unit. In one embodiment, and by way of example only, the system includes an outer can, an annular baffle, and a tube. The outer can has a sidewall including a forward end, an aft end, and a cavity extending therebetween. The sidewall is disposed about a first longitudinal axis, and the cavity has a first cross-sectional area and a smaller second cross-sectional area. The annular baffle is coupled to and extends radially inward from the outer can sidewall and has an opening that is disposed about a second longitudinal axis that is non-coincident with the first longitudinal axis. The tube extends through the annular baffle opening and is spaced apart from the annular baffle to define a radial gap therebetween, comprises acoustic material, and has a length and a substantially uniform cross-sectional area along the length.Type: GrantFiled: August 5, 2005Date of Patent: May 6, 2008Assignee: Honeywell International, Inc.Inventors: Daniel V.
