The present invention relates generally to display systems for helmets and in particular for display systems for motorcycle helmets.
Heads-up display is a display of instrument readings in an aircraft or vehicle that can be seen without lowering the eyes, typically through being projected on to the windscreen or visor. Heads-up displays have been suggested for implementation in a multitude of transportation applications including automobiles, aircraft and motorcycles. A typical heads-up display comprises of three primary components: a projector unit, a combiner, and a video generation computer. The projection unit in a typical heads-up display is an optical collimator setup having a convex lens or concave mirror with a Cathode Ray Tube, light emitting diode, or liquid crystal display at its focus.
The combiner is typically an angled flat piece of glass called a beam splitter which is located directly in front of the viewer that redirects the projected image from projector in such a way as to see the field of view and the projected infinity image at the same time. Combiners may have special coatings that reflect the monochromatic light projected onto it from the projector unit while allowing all other wavelengths of light to pass through.
A motorcycle helmet has to provide adequate deceleration for the human brain in massive impacts. In order to protect the head from the massive impact, various densities of styrofoam are layered between the motorist's head and the outer shell. The helmet is made from a strong material like carbon fiber or plastic, that shell deflects impacts and spreads their energy over a large area.
One of the biggest considerations in motorcycle helmet design is in delivering good crash protection in a package with the smallest possible external dimensions. The smaller a helmet is, overall, the more aerodynamic it will be, and the lower the force with which it may twist a user's head and neck. Heavier helmets also cause muscle fatigue and soreness.
Unlike micro displays, a real heads-up display works by projecting an image onto a clear surface in front of the eyes of the user. In this process, it overlays data on vision, without the wearer having to change his focal point. By making the projected image appear as if it's floating way out in front of you, you can see it without changing the focal distance of your eyes. A real heads-up display empowers users with data in a un-distractive way.
For motorcycles, however, installing a beam splitter in the limited space between the rider's face and the helmet windscreen presents significant design obstacles. Therefore, just sticking a set of big optics and a computer in an existing motorcycle helmet is not the solution to the problem. Also if more information has to be displayed, then there is requirement for increased processor speed and power consumption which is necessary to accommodate the demands. If the above has to be achieved in a wireless environment, then there is a requirement for larger and heavier batteries pack.
Hence there is a need for a motorcycle helmet which is light weight with different advanced features that enhances the usability of the helmet.
The primary objective of the present invention is to provide a motorcycle helmet with heads-up display.
Another objective of the present invention is to provide a motorcycle helmet with 5 inch wide angle rear view camera.
Another objective of the present invention is to provide a motorcycle helmet with technologies like GPS navigation, Bluetooth technology, internet phone chipset, Global system for mobile communications (GSM) Sim card slot, integrated radio with audio and hands-free calling.
Another objective of the present invention is to provide a motorcycle helmet with 3 dimensional laser-cut foam for a perfect fit.
Another objective of the present invention is to provide a motorcycle helmet with anti-fog, anti-scratch and anti-glare visor.
The present invention comprises of a motorcycle helmet having an augmented reality display. According to an illustrative embodiment, the helmet comprises of a full-face motorcycle helmet with heads up display. The motorcycle helmet comes with situational awareness feature wherein the motorcycle rider will be aware of the vehicles which are travelling along with him on the same road and at the same location. The helmet which is described in the present invention also comes with a five inch wide angle rear view camera which displays the live images of the scene behind the rider.
The helmet also includes some advanced technologies like the global positioning system (GPS) navigation which displays the position of the rider on the map along with the complete route map through which the rider can navigate through the location. The helmet is also featured with the Bluetooth technology, internet phone chipset, GSM Sim card slot, integrated radio, hands-free calling and Sirius XM radio. Sirius XM radio offers commercial-free music from every genre, live play-by-play sports, the biggest news and talk, and the hottest entertainment 24/7. The music can be heard at home or the office on the computer, or smartphone and tablet.
The present invention describes the motorcycle helmet with augmented display.
The motorcycle helmet includes a super vent 12, eye port gasket 13, conventional face shield 14, a breath deflector 15, a mouth vent 16, a side vent 17, a chin bar 18, rear vent 19, top pad 20, base gasket 21 and a chin strap 22. Chin bar 18 has a plurality of conventional ventilation intakes which are adjustable to allow a controlled amount of air to enter the helmet for the purpose of reducing fogging of face shield 14 in humid weather and/or for ventilation of the rider. The motorcycle helmet further includes a plurality vents like super vent 12, mouth vent 16, side vent 17, and rear vent 19 which are mainly used for air intakes and ventilation.
The motorcycle helmet includes a visor 2 which is scratch resistant, fog resistant and glare resistant which provides the rider with the clear vision of the vehicles which are moving forward. The helmet also includes an ultra-wide angle rear view camera 10 which captures the panorama view of the area behind the rider which can be enhanced and viewed by the motorcycle rider with the help of the synapse vision enhancement 3 feature which true to life imaging of the rear view panorama display.

The motorcycle helmet is provided with the device which helps in the audio/visual GPS navigation system 4 which displays the location and position of the rider when he is travelling. The display device which is the synapse smart heads-up display system 5 preferably comprises a virtual image display unit consisting of a liquid crystal display (LCD), backlight, collimating optics and magnification optics encased in a single device. In the illustrative embodiment, the VID unit comprises of a 0.59″ WVGA CyberDisplay® display unit manufactured by Kopin Corporation of Westboro, Mass. The motorcycle helmet also comprises of the quick release chin strap 18 which enables the rider to quickly fasten and release the helmet.
The motorcycle helmet is made of 3D laser cut foam 8 with superior quality which gives the rider's head a perfect fit inside the helmet. Also the helmet is provided with a fabric liner 20 for superior comfort. The helmet is certified by the Department of Transport (DOT) and the United Nations Economic Commissions of Europe (ECE) that the helmet is meeting the standard helmet specifications which can protect the rider as the main aim of the helmet is for head protection. The helmet is also provided with additional features like Bluetooth technology which can connect the helmet with other devices through Bluetooth, Internet phone Chipset, GSM SIM card slot in which a SIM card can be inserted, Integrated radio audio facility which provides the radio telecasting to the rider inside the helmet, hands-free calling facility as the rider can listen from inside the helmet.

The power requirements of the motorcycle helmet is fulfilled with the help of the high-capacity battery pack which is embedded in the helmet to provide reasonable service life between charges. The battery pack is rechargeable which has to be charged at regular intervals. The size and weight of the battery is kept in mind as the helmet must not become heavy after the rider wears it as it might cause adverse effects on the motorcycle rider which might damage the neck. The shape of battery pack allows it to fit low and close around the base of the rider's neck extending substantially from ear-to-ear, while the outer surface conforms to the helmet outline. By positioning battery pack low and close around the base of the rider's neck, the moment of inertia of battery pack is minimized relative to the normal turning and tilting motion of the rider's head. Battery pack is easily replaceable using conventional plug-in connectors and releasable catches.
