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.

A system includes an electronic contact lens that obtains sensor measurements from integrated motion sensors or other types of sensors and a processing module that estimates a mental state of an individual based on the sensor measurements. The processing module identifies patterns of eye movements and analyzes how these patterns change over time. Based on anatomical relationships between eye movement and mental state, the processing module estimates characteristics of the individual such as fatigue, intoxication, injury, or a medical condition that have known effects on eye movement patterns. The electronic contact lens system generates an output indicative of the estimated mental state to alert the individual to the detected condition or to initiate an automated action.

An advice target location at which a user had a predetermined emotion, for example, is determined based on location information, user biological information, and user transportation means information, which have been acquired by a terminal device (20) being used by the user. Advice information containing information indicating an advice presentation region set by a server device (50) is generated based on the advice target location. This advice information is supplied from the server device (50) to the terminal device (20), so that the terminal device (20) presents advice. With this, advice as to locations pedestrians find dangerous can be presented to drivers, and advice as to locations drivers find dangerous can be presented to pedestrians. Accordingly, accidents and the like can be prevented.

An assessment system is provided for assessing a performance of at least one autonomous actor in a dynamic environment. The system includes a computer program which, when operating on a data processing system, retrieves input selected from digital information, sensor data and a combination thereof, for detecting and classifying the at least one autonomous actor present in the dynamic environment; sets up a virtual reality simulation of the environment, and synchronizes the simulation with the environment. The program evaluates behavior of the actor in the environment, including measuring, analyzing and classifying actions and reactions of the actor in the simulation while the actor performs at least one predefined procedure in the environment; compares the behavior of the actor with a curriculum including at least one documented procedure and at least one documented performance value of the at least one predefined procedure; and outputs a qualification for the performance.
