This product was jointly developed by Prediction of Sleep Research Group and commercialized by Delta Tooling.,Co,.Ltd. This technology received a Minister's Award of the Ministry of Land, Infrastructure, Transport and Tourism at the Merit Award of the Industry-Academia-Government Coolaboration 2010. |

Sleep Buster captures Aortic Pulse Wave (APW) which occurs in a driver's upper body by a sensor on a car seat. It judges the driver's fatigue state with 6 levels by fluctuation analysis of this APW. This system warns against a change of concentration or a sudden change of a physical condition such as hypnagogic signs phenomenon by using a display and sounds in order to encourage the driver to take a break or a nap. |
