Patent number: 11231389Abstract: Embodiments relate generally to systems and methods for identifying the concentration of an electrolyte. A method may comprise scanning a diagnostic micro-electrode of an electrochemical sensor using scanning voltammetry at a plurality of electrolyte concentrations; generating a variable set of readings from the first scanning voltammetry scan using a potential difference between a strong hydrogen adsorption peak and an oxide reduction peak and/or oxide formation peak at each of the plurality of electrolyte concentrations; and determining a correlation by plotting the variable set of readings and the plurality of electrolyte concentrations.Type: GrantFiled: September 30, 2016Date of Patent: January 25, 2022Assignee: Honeywell International Inc.Inventors: Keith Francis Edwin Pratt, Martin Geoffrey Jones

Patent number: 10895562Abstract: A method and apparatus are provided to determine the composition of one or more gases. In the context of a method, a sensory assembly and at least one processor, the sensor assembly comprising a first gas sensor and a second gas sensor, includes causing the first sensor to be powered to detect a presence of one or more gas while the second sensor is unpowered. The method further includes detecting the presence of one or more gases while the second sensor is unpowered. In response to detecting the presence of the one or more gases, the method includes causing the second sensor to be powered. The method still further includes capturing sensor data corresponding to at least one of the one or more gases. The method also includes identifying the at least one of the one or more gases based on an analysis of the sensor data.Type: GrantFiled: October 15, 2018Date of Patent: January 19, 2021Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Keith Francis Edwin Pratt, Tom Gurd, Cristian Vasile Diaconu, Martin Geoffrey Jones

Patent number: 10191008Abstract: A gas sensor including a gas sensing electrode, a counter electrode disposed within a housing, and respective conductors that connect the gas sensing electrode to the counter electrode via a sensing circuit is disclosed. The housing includes a solid electrolyte in communication with the gas sensing electrode and counter electrode wherein the solid electrolyte further comprises one or more coatings or layers. The one or more coatings or layers have a lower water vapor transport rate than that of the electrolyte, such that, in use, water vapor transport between the electrolyte and atmosphere is reduced.Type: GrantFiled: December 19, 2014Date of Patent: January 29, 2019Assignee: Life Safety Distribution AGInventors: John Chapples, Keith Francis Edwin Pratt, Martin Geoffrey Jones
