Abstract: An automobile windshield rain deflector which functions as a result of a mathematical relationship between rain deflector, forward velocity of vehicle windshield and downward velocity of rain drops; and comprises a shield arranged above the driver's line of vision and is positioned substantially in front of the windshield, with a substantial gap between the deflector shield and the windshield. The shield is connected to a support means for movement between an inoperative orientation to an operative orientation by which a substantially rain free clear vision zone is provided on the windshield. In addition, the support means is movable relative to the windshield to adjust the position of the shield in its operative orientation so that the substantially rain free clear vision zone always coincides with the driver's line of vision regardless of the vehicle's speed or rainfall quantity.

Abstract: A relatively light, compact and variable neck exerciser which is worn and automatically functions throughout the entire range of neck motion as a result of natural effort an individual performs in his or her particular activity; and simultaneously acts as a neck exerciser and neck protector through the entire range of neck motion during this activity, thereby, being a neck rehabilitator. The device includes a looped spring element fastened, in the case of a football player, between the back of the player's helmet at the apex of the looped spring and the back of the player's shoulder pads at the legs of the looped spring. The spring includes compression, torsion and extention spring sections.
