The processor determines the touch location of the contact object based on the aspect ratios of the image and the contact surface, the location of the infrared portion on the image, the area of the infrared portion and the area of the touch portion of the contact object on the contact surface. The controller executes an instruction according to the determined location of the contact object.

Abstract: A printing method for three-dimensional painting by UV digital printing device has acts of: First, preparing a printing device having a white print set and a color print set. Second, moving the printing device transversely from one side to the other side of an object for multiple times, wherein the two print sets respectively print on two adjacent zones. Third, moving the printing device longitudinally to next zone on the object. Fourth, repeating the second and third acts until the printing device moves over a last zone on the object. The printing device moves longitudinally after the printing device moves transversely to and fro to finish the height of a zone. Thus, the printing device completes all the heights and the colors in one time of longitudinal moving. Then printing consumes less time and the printing device therefore does not have to be orientated again.

Abstract: An exemplary gear transmission device includes a driving assembly including a driving shaft, a shaft coupling, a circular driving gear, a resilient mechanism and a driven gear engaging with the driving gear. The shaft coupling is fixed to the driving shaft and rotatable in unison with rotation of the driving shaft. The circular driving gear substantially surrounds and is operatively coupled to the shaft coupling and rotatable under urging of the shaft coupling. The resilient mechanism is held between the driving gear and the shaft coupling and is elastically deformable in circumferential directions of the shaft coupling. When the driving gear moves axially and collides with the driven gear without meshing with the driven gear, the driving gear rotates slightly relative to the shaft coupling thereby elastically deforming the resilient mechanism and the driving gear reaches a position where it can mesh with the driven gear.
