Abstract
A system and a method for aligning two devices with respect to each other are presented. A first device is provided with a proximity switch and the second device is provided with a reference mark. When the second device enters a detection area of the proximity switch, a first state of the proximity switch changes to a second state, thus indicating a position of the second device with respect to the proximity switch. When the position of the second device is known with respect to the proximity switch, the devices may be positioned to a desired position with respect to each other. The proximity switch may be used to determine the position of the other device in a number of directions. Both the position and the orientation of the first device with respect to the second device may be determined using the proximity switch.
