Abstract: A system to determine a relative position between a moveable part and a working surface is disclosed. The system comprises a controller to control a light emitter from an array of light emitters to emit a signal at a setting, the setting being indicative of a position associated with the light emitter. The controller further to receive a signal from the sensor indicative of the setting. The controller also to determine the relative position between a moveable part and the working surface based on the signal.

Abstract: In an example, a method comprises receiving a digital representation of a floor plan to be printed by a surface marking robot guided using a remote guiding system, receiving guiding system position information, and receiving obstacle information identifying an obstacle. The method also comprises identifying a specific floor plan feature of the digital representation which intersects a shadow region of the obstacle from a guiding system point of view, and, in response to this, modifying the digital representation to produce a second digital representation, whereby the specific floor plan feature is either deleted or modified in the second digital representation, the modified floor plan feature excluding at least a portion of the specific floor plan feature in the shadow region. The method also comprises operating the surface marking robot to print the second digital representation using the guiding system.

Abstract: Methods and apparatus for sublimation printing are described, in which a printed textile medium with a sublimating printing substance on a print side is positioned in correspondence with a heating device, with the print side facing away from the heating device, and a negative pressure is caused on the print side of the textile medium, to cause heated air to flow through the printed textile medium thereby sublimating the sublimating printing substance on the printed textile medium.
