Patent number: 11609219Abstract: A gas analyzer uses continuous sonic signals through a conduit to determine the composition of a gas in the conduit. A transmitting transducer drives sonic signals at a fixed frequency and a second transducer receives the sonic signals. The phase shift between two signals corresponds to the speed of sound through the gas and is related to the composition of the gas. The electronic versions of these signals are processed by lowering, or dividing, the fixed frequency which expands the range of phase shift measurement and allows the determination of an expanded range for the gas composition. In an ozone generation system, the gas analyzer is highly suitable for determining the composition of gases derived from air as a gas of known composition and a calibration point.Type: GrantFiled: August 1, 2019Date of Patent: March 21, 2023Assignee: Evoqua Water Technologies LLCInventor: Philip Tinsley Dempster

Patent number: 10488397Abstract: Improved sensor assemblies are provided. More particularly, the present disclosure provides improved and highly advantageous metal oxide based sensor assemblies configured to sense low concentration of specific gases, and related methods of use. The present disclosure provides improved physical forms of metal oxide films (e.g., WOx films, CeOx films). The exemplary metal oxide films can be fabricated by a Reactive Spray Deposition Technology (RSDT). The highly advantageous films/materials can be utilized in sensor assemblies to detect simple chemical components of the breath that correlate with human health conditions (e.g., the presence of acetone in diabetic patients). These films/materials demonstrate improved thermal stability under the sensor's operating conditions, as well as improved sensitivity to low concentration of the analyte, selectivity and quick responsiveness.Type: GrantFiled: April 4, 2017Date of Patent: November 26, 2019Assignee: University of ConnecticutInventors: Radenka Maric, Rishabh Jain

Patent number: 10467460Abstract: In devices that determine levels of substance use, a substance level in a test sample provided to the testing device by a test subject is determined. A sequence of images are captured to include a portion of the face of the test subject providing the test sample and a display of the testing device. A value indicative of the substance level detected within the test sample is determined. A validity indicator indicating validity of the value indicative of the substance level is determined. A current location is determined. The value indicative of the substance level, the validity indicator, and the current location are sent to a remote server.Type: GrantFiled: December 29, 2016Date of Patent: November 5, 2019Assignee: ROBERT F. NIENHOUSE 1997 DECLARATION OF TRUSTInventor: Robert Frank Nienhouse

Patent number: 10222357Abstract: The monitoring breathalyzer has an alcohol sensor, a processing unit or processor, and a screen. The processing unit determines the accuracy of the breathalyzer using the user's body as a simulator. In monitoring mode, the processing unit receives a BAC measurement from the alcohol sensor based on the breath sample provided by the user at a sample time and determines a reference point from the BAC measurement. The sample time is determined based on a time to a predetermined calibration point from a drink start time.Type: GrantFiled: February 3, 2017Date of Patent: March 5, 2019Assignee: AK GLOBALTECH CORP.Inventors: Matthew Hogyun Son, Jung Hoon Son

Patent number: 9921140Abstract: A system for tracking one or more subjects for collecting airborne contaminants. The system includes one or more subjects configured to collect air contaminants. Each of the one or more subjects includes an identification tag encoded with identification information identifying the each subject. The system further includes an identification reader configured to decode the identification information encoded within the identification tag of a scanned one of the one or more identification tags. A computer receives and stores the decoded identification information in a record in a database. The computer may also receive and stored an identification code for a user who scanned the scanned identification tag in the record in the database. Additional records in the database are created each time the identification tag of one of the one or more subjects is scanned. The one or more subjects are thereby tracked as they collect airborne contaminants and are incubated.Type: GrantFiled: May 18, 2017Date of Patent: March 20, 2018Assignee: Veltek Associates, Inc.Inventors: Rosario S. Calio, Mark A. Phillips, John Joyce

Patent number: 9897591Abstract: The system is of the type for use by a person and including a handpiece and an imaging device, the handpiece containing a breath alcohol tester and the imaging device being adapted to capture an image including the handpiece when a breath sample is delivered to the handpiece. The improvement includes a sensor arrangement and a computing functionality. The sensor arrangement is adapted to provide information from which an orientation and position of the handpiece can be calculated. The computing functionality is adapted to: generate a calculated orientation and position of the handpiece; and if a face appears in the image, precisely locate the features thereof. The features of the face are located using the calculated orientation and position of the handpiece.Type: GrantFiled: September 21, 2015Date of Patent: February 20, 2018Assignee: Alcohol Countermeasure Systems (International) Inc.Inventor: Exequiel Rarama

Patent number: 9696294Abstract: A breath alcohol testing device has a removable tamper-resistant sampling chamber assembly that provides a disposable interface between the test subject and the alcohol sensor, other sensors and electronics of the testing device. Hydrophobic membranes prevent bodily fluids and other liquids from entering the alcohol sensor and other sensitive components of the testing device. A set of chambers with one-way valves direct the gas flow within the sample chamber assembly to ensure the breath sample delivered to the alcohol sensor is not diluted by the subject inhaling, and is a deep-lung breath sample.Type: GrantFiled: June 3, 2015Date of Patent: July 4, 2017Assignee: Integrated Monitoring Systems, LLCInventor: Brian K.
