A head-gear mounted bone-conducting microphone includes a housing attachable to a helmet and a transducer housed in a flexible shroud. The shroud is attached to the housing. A resilient material is disposed within the shroud. A void is provided between the resilient material and the housing to prevent the transducer from transmitting vibrations directly from the housing to the transducer. This configuration allows the microphone to effectively mechanically isolate the minuscule vibrations associated with speech from the enormous vibrations associated with most loud environments (machinery, equipment, transportation, aircraft, tanks, construction, sporting events, etc.).

An apparatus, system and method for ski training are disclosed herein for providing feedback to a skier regarding the orientation of their skis. The apparatus, system and method measure various distances between a first ski and a second ski, determine an angle between the first ski and the second ski based on information representative of various distances; and provide an indication of the measured angle.

The flexible electronic control unit 61 for helmet strap with safety, emergency and driving assistance functionalities can be installed around helmet strap 62, independently from helmet configuration. The electronic control unit is structured to execute Emergency Call or its equivalent in case of accident or fall, taking account of the related European and International regulations, with real-time transmission of user's blood pressure profile and/or derived measures to PSAP and the like while emergency call is ongoing as to support rescue organization. The electronic control unit implements also driving assistance functionalities and remote connection with vehicle control units, such as the peculiar generation of sound alert to reduce vehicle speed as a consequence of uneven bumpy street asphalt detection, as well as the peculiar generation of a synthetized voice message to the user for indications coming from the vehicle about adherence conditions and further information about its own status while travelling.
