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. Phillips

Patent number: 9575470Abstract: A biometric identity confirmation system is based on both pulse wave shape data and spirometric data for the subject. During an initial enrollment mode, pulse wave shape and spirometric data for a known subject are used to generate subject characterization data for the known subject by computing an exemplar and selectively weighting portions of the exemplar based, for example, on repeatability or distinguishing characteristic features over the population of known subjects. During a subsequent identity authentication mode, pulse wave shape and spirometric data for a test subject are analyzed using the subject characterization data to confirm whether the identity of the test subject matches the known subject.Type: GrantFiled: February 24, 2016Date of Patent: February 21, 2017Assignee: Integrated Monitoring Systems, LLCInventors: Brian K. Phillips, Geoffrey A. Wilson

Patent number: 9398858Abstract: A portable testing unit for biometric identity confirmation includes a housing with an orifice to receive a breath sample from the test subject, a spirometric sensor, and a pulse sensor adjacent to the orifice. A processor analyzes spirometric data from the spirometric sensor and simultaneous pulse wave data from the pulse sensor during the breath sample, together with stored subject characterization data for a known subject to confirm whether the identity of the test subject matches the known subject. A communications link enables the processor to communicate to the external station whether the identity of the test subject matches the known subject. For example, this portable testing unit can be used to control access to a secure facility or computer, authenticate the identity of a party in a financial transaction, or confirm the identity of the subject of an alcohol monitoring test.Type: GrantFiled: December 6, 2012Date of Patent: July 26, 2016Assignee: Integrated Monitoring Systems, LLCInventors: Brian Kirby Phillips, Geoffrey A.

Patent number: 9223298Abstract: A biometric identity confirmation system is based on pulse waveform data for the subject. During an initial enrollment mode, pulse waveform data for a known subject are used to generate subject characterization data for the known subject. The subject characterization data includes an exemplar created by synchronous averaging of pulse waveform data over multiple pulse cycles. A number of trigger candidate are identified for the start point of each pulse cycle. The time delay between trigger candidates is analyzed to discard false trigger candidate and identify true candidates, which are then used as the start points for each pulse cycle in synchronous averaging of the pulse waveform data. During a subsequent identity authentication mode, pulse waveform data for a test subject are analyzed using the subject characterization data to confirm whether the identity of the test subject matches the known subject.Type: GrantFiled: June 13, 2013Date of Patent: December 29, 2015Assignee: Integrated Monitoring Systems, LLCInventors: Brian K.

Patent number: 8773239Abstract: A method and system for biometric identity confirmation is based on the pulse wave of a subject. During an initial enrollment mode, pulse wave data for a known subject are used to generate subject characterization data for the known subject. During a subsequent operational mode, pulse wave data for a test subject are analyzed using the subject characterization data to confirm whether the identity of the test subject matches the known subject. The subject characterization data can be a probability density in a phase space in which at least two quasi-periodic variables based on the pulse wave (e.g., blood pressure and volume time-series data) are correlated.Type: GrantFiled: April 4, 2011Date of Patent: July 8, 2014Assignee: Integrated Monitoring Systems, LLCInventors: Brian K.

Publication number: 20120330175Abstract: An system for monitoring alcohol in the breath of a test client confirms the identity of the test client based on spirometric data. The system includes a sample chamber receiving a breath sample, an alcohol sensor measuring the alcohol content of the breath sample, and a spirometric sensor generating spirometric data from the breath sample over the test clients entire exhalatory phase. A processor analyzes the spirometric data with stored client characterization data for a known client to confirm the identity of the test client. The client characterization data can be a probability density in a phase space in which at least two spirometric variables (e.g., flow and volume time-series data) are correlated.Type: ApplicationFiled: June 27, 2011Publication date: December 27, 2012Applicant: INTEGRATED MONITORING SYSTEMS, LLCInventors: Brian K.
