Publication number: 20220306347Abstract: A plug for a container for storing liquid includes a housing and an input end at an end of the housing, where the input end allows gas flow to pass through. A first sensor is in a first sensor chamber inside the housing, the first sensor being configured to detect a phenol. A first filter is between the input end and the first sensor, where the first filter selectively allows the phenol to pass through. A first flow pathway is between the first input chamber and the first sensor chamber.Type: ApplicationFiled: June 10, 2022Publication date: September 29, 2022Applicants: Simple Labs, Inc., KWJ ENGINEERING, Inc.Inventors: Michael Slone, Melvin Findlay, Joseph R.

Patent number: 11378569Abstract: A plug for a container for storing liquid includes a housing and an input end at an end of the housing, the input end having a liquid-impermeable membrane that allows gas flow to pass through. A first sensor is in a first sensor chamber inside the housing, the first sensor being configured to detect a smoke taint compound. A first filter is between the input end and the first sensor, where the first filter selectively allows phenols to pass through. A second sensor is in a second sensor chamber inside the housing, the second sensor being configured to detect a second substance different from the smoke taint compound. A second filter is between the input end and the second sensor, wherein the second filter selectively allows the second substance to pass through.Type: GrantFiled: August 30, 2021Date of Patent: July 5, 2022Assignees: Simple Labs, Inc., KWJ ENGINEERING, Inc.Inventors: Michael Slone, Melvin Findlay, Joseph R.

Patent number: 10966631Abstract: A breath sampling device including a housing having a fluid inlet positioned at a fluid inlet end, a fluid outlet positioned at a fluid outlet end, a fluid channel extending between the fluid inlet and the fluid outlet, and a sensor fluidly coupled to the fluid channel. The sensor is structurally configured to detect a presence of a target gas in a gas sample and a filter assembly fluidly coupled to the fluid channel and positioned between the fluid inlet and the sensor. The filter assembly is structurally configured to absorb heat, water vapor, or a combination thereof.Type: GrantFiled: September 11, 2015Date of Patent: April 6, 2021Assignee: Sensirion AGInventors: Joseph R. Stetter, Vinay Patel, Melvin Findlay

Patent number: 9213016Abstract: Systems and methods for automated self-compensation are described herein. Accordingly, some embodiments of a method may include measuring a signal from an electrochemical sensor device, where the signal relates to the presence of a predetermined gas, and where the electrochemical sensor device includes a potentiostat, measuring an internal property of the electrochemical sensor device by electronically pinging the potentiostat, and receiving a response from the potentiostat. In some embodiments, the method may include interpreting the response through an associative relationship between the electrochemical sensor device and a data acquisition and calculation module, determining an effect of an environmental factor from the response, compensating for effects of the environmental factor by adjusting the signal from the electrochemical sensor device and outputting the adjusted signal.Type: GrantFiled: August 21, 2014Date of Patent: December 15, 2015Assignee: SPEC Sensors, LLCInventors: Joseph R. Stetter, Melvin Findlay, Bennett J. Meulendyk

Patent number: 8795484Abstract: A printed gas sensor is disclosed. The sensor may include a porous substrate, an electrode layer, a liquid or gel electrolyte layer, and an encapsulation layer. The electrode layer comprises two or more electrodes that are formed on one side of the porous substrate. The liquid or gel electrolyte layer is in electrolytic contact with the two or more electrodes. The encapsulation layer encapsulates the electrode layer and electrolyte layer thereby forming an integrated structure with the porous substrate.Type: GrantFiled: January 14, 2013Date of Patent: August 5, 2014Assignee: KWJ Engineering, Inc.Inventors: Joseph R. Stetter, Edward F. Stetter, Daniel D. Ebeling, Melvin Findlay, Vinay Patel
