Abstract: The adjustable mount comprises a baseplate, a platform separated from the base by at least three columns, and a mounting element adapted for engagement with the image projector. The columns are at a first end connected to one of said platform or said baseplate, and remote from said first end pass through apertures in the other. The apertures comprise, a first circular aperture with a diameter corresponding essentially to the diameter of the column passing through it, a second circular aperture with a diameter larger than the diameter of the column passing through it, a third elongate aperture having a length and a width, where length is longer than the diameter of the column passing through it and where the width corresponds essentially to the diameter of the column passing through it.

Abstract: A system and a method for securing electric apparatus, that includes at least one transmitter transmitting at least one coded signal, and where the system includes at least one electric apparatus interacting with at least one decoder. To prevent electric apparatus from being used in other places than where intended, a one-way communication system causes the apparatus to lose their practical value if they are stolen. Activation of the electric apparatus is conditional on the transmitter transmitting a coded signal to at least one decoder that receives the coded signal and interacts with at least one electronic switch for establishing power supply to the apparatus. By using a device that switches off the power supply or other essential electric circuit for the electric apparatus in case that the decoder does not receive and decode the transmitted signals, it is possible to protect electric apparatus very efficiently against theft.
