Abstract: The present invention discloses a system for remotely controlling a light. In the preferred embodiment, a standard remote control is used to turn a light level to a performance setting. The system has means for receiving (62), learning (64), locking and unlocking (66) the learning mode as well as a means to control (68). Importantly the standard remote control is used to configure the system, locking the device in and out of a learning mode as well as to control. This makes it possible for the device to be out of reach of the user with no need for a manual user interface. The invention does not require isolation for configuring the system which reduces cost and complexity and has safety advantages in certain cases. In the locked mode the device becomes highly immune from corruption such as infrared ‘noise’ and secure from being controlled inadvertently.

Abstract: A demountable hanger assembly, for mounting at various locations in a display panel, has a cylindrical socket of predetermined diameter, a magnet mounted within the socket; a hanger locating device mounted within the socket adjacent to the magnet; a hanger member having a cylindrical portion to make a snug sliding fit in the socket, the cylindrical portion at least being formed of a magnetically sensitive material, attracted to the magnet, a locating recess formed in the cylindrical member to interfit with the locating member in the socket; and a hanger extending outwardly from the cylindrical portion, the hanger member being demountable from and mountable in the socket by manually separating the cylindrical member from the magnet.
