An organization in the USA is striving to improve acceptance of alco-lock sensors. Since before they have had a close cooperation with Senseair as well as other Swedish companies within the field of automotive safety. One key issue is to improve the detection limit of the sensor in order to minimize the inconvenience of the driver.
A one-year project was formed with the goal to improve the resolution of the sensor by adjusting the optical setup, trimming the signal chain, improving signal stabilization and switching key components. The budget for Senseair was 900 000 USD, and the project was closely coordinated with other partners that also improved driver convenience.
The project is carried out in close cooperation with the financing organization, resulting in three times improvement of the detection limit. Scientists from the research department and sub-contractors are involved, as well as hardware-, software and test engineers. Also close collaboration with several sub suppliers is required in order to get maximum gain from each critical sub-component. In-house designed optical test equipment has to be built and shipped to sub suppliers for process optimization. As of now 200 sensor prototypes have been produced and shipped to the funding partner for further evaluation and field tests in the USA.
The project also presented a pre-study showing how to further gain three times more as well as the estimated effort to reach that. A new one-year research project with new goals and a new budget was formed.
This sensor can now be found under our breath sensing product Sober Workplace and Sober Transportations. More about the research under over Driver / Sensor inVehicle
