People who wear full-face motorcycle helmets usually have some difficulty making themselves understood by the unhelmetted subspecies of people. This can lead to unfortunate hand gesturing etc.
Today’s invention is a microphone to be worn inside a helmet which then feeds to a loudspeaker on the outside. This allows better communication with fellow road users and pedestrians (eg ‘Get out of the way please’).
In the event of an accident, the system could be arranged so that when in a lying down orientation for more than say 30 seconds, it issues certain messages automatically eg ‘Do not remove helmet’ ‘Call 999’ ‘My name is Tom, call 0181 223 334’ etc pre-recorded in the voice of the wearer.
