Abstract: The lens of the subject corrective eyeglasses obstructs the vision of a preselected area but not the whole of the wearer's stronger eye, either by impairing his vision or entirely blocking it. When the vision is so obstructed, the wearer's weaker eye is forced to compensate for the stronger eye's loss by taking over the area of sight not visible by the stronger eye. The lens may be obstructed by applying over the preselected area of the lens a coating which distorts or blurs the object seen by the eye. Alternatively an opaque coating may be applied to the preselected area to entirely block the object. In either case, the wearer is forced to use his weaker eye to see the object impaired or blocked by the coating.

Abstract: The invention relates to a solar power system comprising a plurality of mounting supports (50), a plurality of photovoltaic modules (1) mounted on the mounting supports (50), a plurality of holding elements (60, 100) for holding the photovoltaic modules (1) on the mounting supports (50) and a plurality of electric connecting elements (60) for electrically interconnecting the photovoltaic modules, and wherein the electric connecting elements (60) comprise two electrically contacting connecting plugs (40-43, 70-74) which can be plugged together and which are designed such that they are plugged together with the mounting movement of the respective photovoltaic module when mounting it on a mounting support (50).

Abstract: An apparatus for handling tubular goods which includes an elongate body having a coupling end adapted for mating engagement with a tubular good. The coupling end includes a structural member, a flexible cylindrical cage and a pressure member. Longitudinal strips joined at their opposed ends form the cage coaxial with and connected to the structural member of the body. The coaxial pressure member is disposed in an annulus between the structural member and the cage. The pressure member is adapted to cause radial displacement of the cage, thereby exerting a gripping force to maintain the mating engagement between the tubular good and the coupling end enabling a transfer of force between the body and the tubular good.
