Abstract: In one embodiment, a female electrical connector comprises a socket having slots and electrical contacts. At least one of the electrical contacts can be movable between an open electrical circuit position where the electrical contacts are not in electrical communication and the socket is electrically inactive and a closed electrical circuit position where the electrical contacts are in electrical communication and the socket is electrically active. In one embodiment, an electrical box can comprise a container formed from a base having sides extending therefrom to define a cavity and the female electrical connector.

Abstract: In one embodiment, a light comprises: a body portion, a base, and an electrical power cord connected to the body and capable of establishing electrical communication between the light source and an electricity source. The body portion can comprise a lens, a light source, a reflector, a body connection, and a focusing element. The focusing element can be configured to create relative movement between the light source and the reflector, such that, when in use, a spread of a light beam from the light source can be adjusted. The base comprise can comprise a mounting element and a base connector capable of connecting to the body connection.

Abstract: In one embodiment, an electrical box can comprise: a container formed from a base having sides extending therefrom to define a cavity; a cover configured to cover the cavity when in a closed position; and a female electrical connector disposed in the cavity when the cover is in the closed position. A socket of the female electrical connector can be capable of receiving a male electrical connector. Even when the electrical box is connected to live wiring, when the cover is in an open position, current cannot flow to the socket, and when the cover is in a closed position, current can flow to the socket. In another embodiment, an electrical box can comprise: a container; a cover configured to cover the cavity when in a closed position; and a female electrical connector physically connected to the cover such that the female electrical connector moves as the cover is opened.

Abstract: A system for displaying images on a basketball goal is disclosed. The system comprises a basketball backboard comprising at least a portion of a laminated panel that appears frosted. An electrical source is electrically coupled to the laminated panel such that the electrical source is configured to transmit a voltage to the laminated panel to render it clear. A projector is configured to project an image onto the laminated panel when the laminated panel appears frosted. A controller is configured to transmit signals to the electrical source and the projector. The signals relay information to activate and deactivate the electrical source and the projector.
