    摘要: The present invention relates, in various embodiments, to automated detection of head and/or head-affecting body impact events in data collected via instrumented mouthguard devices. For example, in some embodiments the invention relates to training and operation of an impact classifier system, which is configured to identify head affecting impacts from time-series data collected by an instrumented mouthguard device. Some embodiments relate to a two-stage method for processing impacts, including a first stage in which a set of data is classified by such an impact classifier system, and a second stage whereby impacts classified as head affecting impacts are designated a numerical value based on a predefined scale.

    摘要: At least one detector (2) for visible and/or IR radiation on board of a vehicle (100) is used to determine if an entity (200) is approaching the vehicle (100). If so, sensors (4) for vibration and/or acceleration are activated. Signals from these sensors (4) are used to determine if a contact between the entity (200) and the vehicle (100) has occurred. The contact may be classified based on these signals. The at least one detector (2) may include a camera (21). At least one camera (5, 21) on board of the vehicle may be used to record image data pertaining to a time-interval about the contact. A warning may be triggered if a contact between the entity (200) and the vehicle (100) is likely.
