Light energy absorbing and filtering device for a motorcycle helmet
Abstract
Abstract A DEVICE THAT ADJUSTS THE TYPE AND DEGREE OF SHIELDING OF THE EYES FROM ELECTROMAGNETIC RAY ENERGY FROM THE SUN BY PRESENTING DIFFERENT DEGREES OF SCREENING AND FILTERING OF THE DRY ENERGY, THE DEVICE HAVING A WINDOWTYPE SHIELD THAT IS FORMED FROM SPACED LAYERS OF TRANSPARENT MATERIAL THAT ARE EDGE SEALED TO PROVIDE A THIN LIGHT TRANSMISSION CAVITY THEREBETWEEN AND A CONNECTING STORAGE CONTAINER WITH VALVE MEANS AT THE CONNECTION BETWEEN THE CAVITY AND THE CONTAINER. THE DEVICE HOLDS TWO IMMISCIBLE LIQUIDS OF SUBSTANTIALLY EQUAL VOLUME THAT HAVE DIFFERENT SPECIFIC GRAVITIES SO AS TO MAINTAIN SEPARATE LIQUID BODIES WITHIN THE DEVICE. BY OPENING THE VALVE MEANS COMMUNICATION IS ESTABLISHED BETWEEN THE CONTAINER AND THE CAVITY AND TILTING THE DEVICE EXCHANGES THE LIQUID BY GRAVITY, AT WHICH TIME CLOSING OF THE VALVE MEANS MAINTAINS THE EXCHANGED LIQUID IN THE CAVITY TO PRODUCE THE DESIRED CHANGE IN SHIELDING EFFECT.
