Patent number: 11964558Abstract: Methods and apparatus allow for passive determination of a driver's Breath Alcohol Concentration (BrAC). Alcohol concentrations can be determined from exhaled breath, however inconvenience to a driver is often a barrier for incorporation of BrAC sensors into vehicles. The methods and apparatus allow for passive determination of a driver's BrAC, while detecting and accounting for a wide range of environmental conditions that may reduce the accuracy of a passive BrAC reading.Type: GrantFiled: August 31, 2021Date of Patent: April 23, 2024Assignee: Automotive Coalition for Traffic Safety, Inc.Inventors: Bertil Hök, Raimo Gester, Jonas Ljungblad, Håkan Pettersson

Publication number: 20230286466Abstract: The present invention relates to a breath analyzing system and method. In particular the invention relates to a breath analyzing system and method arranged to provide tracer-aided determination and classification of the presence of a breath intoxicating substance facilitated by a user interaction scheme. If a determination may not be performed within a first compliant mode of operation an interactive mode is initiated wherein the user is stepwise instructed to perform actions that facilitate the classification. An action compliance value, representing how well the user follows issued actions/instructions, is determined and used to select actions.Type: ApplicationFiled: July 8, 2021Publication date: September 14, 2023Inventors: Bertil Hök, Jonas Ljungblad

Publication number: 20230051132Abstract: The present invention relates to a breath analyzing system and method. In particular the invention relates to a breath analyzing system and method arranged to provide tracer-aided classification of the presence of a breath intoxicating substance above a limit concentration and providing status to a user about the progression of the classification. The method/system detects a peak in the tracer signal and defines an evaluation period corresponding to the duration of the peak. Measurements classification of the concentration of the intoxicating substance is used for the evaluation period, and if required to achieve a result, for a plurality of evaluation periods.Type: ApplicationFiled: January 29, 2021Publication date: February 16, 2023Applicant: SENSEAIR ABInventors: Jonas LJUNGBLAD, Bertil HÖK, Martin ÅHLENIUS

Publication number: 20230043348Abstract: The invention relates to a breath test system that is unobtrusive in that it does not require a person subjected to the system to take any other action to breath. It comprises a sensor unit (5) configured to sense the presence or concentration of a volatile substance, present in air flowing through a predefined inlet area (4), and to generate a signal corresponding to the concentration of said substance. There is also provided an apparatus (2, 3) configured to detect the presence of a person at a position in the vicinity of said input area, and having means for registering said presence, and further configured to respond to said presence by delivering an output. This said apparatus includes a unit configured to call for immediate attention of said person, upon said registration of the presence of said person, and a unit configured to provide instructions to said person to direct an expiratory air flow towards said inlet area (4).Type: ApplicationFiled: July 19, 2022Publication date: February 9, 2023Inventors: Bertil Hök, Lars Tenerz, Leif Smith, Annika Kaisdotter Andersson
