Solution: 1> press the "reset" key to reset the system. 2> open the wind shield and enable the left and right pressure plates respectively. Perform the following checks in sequence: 3> check for fiber breakage. 4> check whether the optical fiber cutting length is too short. 5> check whether the fiber slot matches the optical fiber. And perform corresponding processing. 5. The optical fiber can be properly reset. When the gap is set

Finger-Friendly Interactive design: Designed for better clicks

When playing darts, the bull's eye is the most difficult position to hit, because the bull's eye is the smallest part of the entire target area. The smaller the goal, the more difficult it is to achieve. This guideline also applies to the touch screens of mobile devices. As we all know, for touch screen equipment users, small area of the target than the size of the target more difficult to manipulate. Therefore, in the design of mobile device interface, touch target must be sufficiently large e

common. 3. Touch Pad Area Size Key sensor disk Area size: Min 4mmx4mm, Max 30mmx30mm. The actual area size depends on the sensitivity, and the area size is proportional to the sensitivity. In general, the diameter of the key sensor disk is greater than 4 times times the thickness of the panel, and increase the size of the electrode, can improve the signal-to-noise ratio. The shape and area of each sensor disk should be the same, to ensure consistent sensitivity. Typically in most applications,
