Apparatus to be detachably fixed on a mounted glazing panel and associated method

An apparatus configured to be detachably fixed on a glazing panel mounted on a stationary object or on a mobile object, the apparatus comprising:

• a fixing frame having a fixing frame plane, FFplane, defined by a longitudinal axis X and a transversal axis Y,
• a light emission element,
• at least a first motor configured to move the light emission element in a first direction essentially parallel to FFplane,
• at least a second motor configured to move the light emission element in a second direction that is orthogonal to the first direction and essentially parallel to FFplane,
• wherein the apparatus further comprises:
• at least N suction means, wherein N is a positive integer (N>0), comprising:
• a suction end, detachably fixed to the glazing panel, defining a resting distance, Drest, between the FFplane and the suction end, measured in a direction normal to FFPlane, when the apparatus is not fixed to the glazing panel, also defining a working distance, Dwork, between the FFplane and the suction end, measured in the direction normal to FFPlane, when the said apparatus is detachably fixed to the glazing panel;
• at least M rigid pushing means, wherein M is a positive integer (M>0), comprising:
• a pushing end defining a pushing distance, Dpush, between the FFplane and the pushing end, measured in the direction normal to FFPlane;
• wherein a sum of the positive integers M and N is equal to or greater than 3 (M+N≥3) and wherein Dpush is equal to or greater than Dwork (Dpush≥Dwork).
