Abstract: An input device may include various sensor electrodes that detect positional information of an input object in a sensing region of the input device. The input device may include a first sensor electrode that detects a first change in a first variable capacitance in response to a deflection of a conductive layer by the input object. The input device may include a second sensor electrode that detects a second change in a second variable capacitance in response to the deflection of the conductive layer by the input object. The first change in the first variable capacitance and the second change in the second variable capacitance may determine an acquired force image of the input force. An adjusted force image may be determined from the acquired force image using the positional information.

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 obstacle and cliff avoiding system is disclosed, which is substantially a movable chassis having at least a displacement sensor arranged thereon. In a preferred embodiment, each displacement sensor is tilted by a specific angle with respect to a surface detected thereby while being driven to move in circle by a rotating apparatus for enabling the same to scan a defined fan-like area or the circular area around the chassis in a circulating manner. As each displacement sensor is tilted by the specific angle and is initiated to issue a working signal, the paths of signal emission and reception of each sensor are defined by the specific angle, whereas the reflected working signal received by the sensor is sent to a control unit to be compared with the working signal so that the control unit is able to evaluate whether there is an obstacle or a drop in front of the moving direction of the movable chassis and thus control the chassis to maneuver around the obstacle or the drop.
