US Patent 10098401 Augmented reality motorcycle helmet

An augmented-reality helmet which in one embodiment is a full-face motorcycle helmet with a look-down micro-display that projects a virtual image in-line with the helmet's chin bar. In order to accommodate the power requirements, the helmet includes a battery pack mounted at the base of the motorcyclist's skull. A wind turbine charges the batteries. Exhaust from the turbine is then deducted through the helmet to cool the battery pack and/or the motorcyclist's head. The turbine is controllable so that it can operate as a circulating fan to provide ventilation. A digital gyroscope provides a control input to a controller for operating a steerable headlight of the motorcycle to track the rider's head movements; and provides acceleration output to an algorithm that will contact emergency responders if the rider is non-responsive after a collision. A 170 degree rear-view camera is mounted within an aerodynamic fairing on the back of the helmet.
