Abstract: A floating solar photovoltaic device includes a plurality of solar photovoltaic modules, each of the solar photovoltaic modules being connected by cords to an internal frame and the internal frames being arranged in an array of rows and columns. The cords can permit movement of one of the solar photovoltaic modules to be independent of movement of another of the solar photovoltaic modules. The cords can restrict movement of one of the solar photovoltaic modules to prevent collision with another of the solar photovoltaic modules. The cords can diminish transfer of forces bearing on one of the solar photovoltaic modules to another of the solar photovoltaic modules.

Abstract: Provided herein is a floating photovoltaic solar device designed to reduce the effect of wind forces without the use of external control or power. The device includes a floating anchored frame with a means for connecting an internal corded lattice; a corded lattice suspended within the floating frame and forming a set of polygonal cells in which independently floating solar photovoltaic modules are positioned. Access for scheduled and unscheduled maintenance may be provided by a floating service gantry. The system is modular and several devices may be connected in a honeycomb-like structure.

Abstract: Disclosed herein is method of locking and unlocking a door that is equipped with an electronic lock, to be locked and unlocked with a removable mechanical lock, enabling orthodox Jews that observe the Sabbath laws to use the door on Saturdays. Also disclosed herein is how to fortify a hotel room door by adding a removable mechanical proprietary lock over the built-in electronic lock. These modifications can be done without damaging the door.
