Abstract

The system (100) for positioning a movable electrical socket (133) comprises at least one planar support element; on a first side of each support element, a rail system comprising fixed rails extending in a first direction and at least one second rail extending in a second direction perpendicular to the first direction and connected to the first rails, wherein the at least one second rail is motor-driven and movable in the first direction relative to the first rails; a power transmission transmitter (120) connected to each of the second rails, each of said transmitters (120) is motor-driven and movable in the second direction along said second rail, and which transmitter (120) comprises a magnetic retainer (122); on each side of each support element opposite the first side thereof, at least one energy receiving receiver (130) comprising an electrical socket (133) and wirelessly connected to the transmitter (120) by resonant inductive coupling for receiving electrical energy to power an electrical appliance connected to said electrical socket (133), said receiver (130) being in a magnetic engagement through a magnetic retainer (132) with the magnetic retainer (122) of the transmitter (120) and is movable in a fixed position relative to said movable transmitter (120); a power transfer control unit (140) for supplying electrical power to the transmitter (120); a motion control unit (150) for operating the motor (107; 121) of the at least one second rail and the associated transmitter (120). The system further comprises a camera system (160) comprising cameras (162) for monitoring the movement of a user in the space defined by the second side of the at least one planar support element; a central computer (170) for receiving signals from the cameras (162) and determining at least the spatial position of the user on the basis of images provided by the camera system (160), the central computer (170) is configured to generate motion control signals for the motors (107; 121) of the second rail and the transmitter (120) based on at least the spatial position of the user and to send said motion control signals to said motion control unit (150) for moving the transmitter (120) into a target position according to the spatial position of the user, and further to send power control signals to the power transfer control unit (140). The central computer (170) is programmed to drive the motors (107; 121) of a second rail (106) and a transmitter (120) for moving the transmitter (120) along the support element so that the receiver (130) magnetically attached to the transmitter (120) always stay within a predetermined distance from the user.
