The present invention is a device for measuring and displaying the speed, force, rate and/or frequency that an object or a body part strikes a target. The present invention includes an impact sensor, transmitter, computer and display. The sensor includes layers of alternating conductive and non-conductive material that are wrapped around the target. The conductive layers of fabric generate electrical impulses when they come into contact with each other through perforations in the non-conductive material. These signals are interpreted by the computer to derive information about the speed of the strike against the target.

A pressure sensor for being mounted in a vehicle door includes a housing, a pressure transducer, an elastomeric connector, and electrical conductors for facilitating an electrical connection to the pressure sensor. The pressure transducer is mounted in the housing adjacent the elastomeric connector. The housing is configured to exert a force that presses the pressure transducer against the elastomeric connector. The elastomeric connector comprises electrically conductive regions configured to be pressed against electrical contacts of the pressure transducer and the electrical conductors to establish and maintain an electrical connection between the pressure transducer and the electrical conductors.

A mouth guard senses an impact event and generates impact data associated with the impact event. The impact data can be analyzed to determine whether the impact event is a true impact event or a false impact event. The impact data can be analyzed by a trained model. The impact data can be labeled after independently determining whether the impact event was a true impact event or a false impact event. The labeled impact data can be used to update the model.
