Patent ID: 8355010

Claim:
A load cell touch control device, comprising: a touch panel which receives a stress applied to a special position thereon; a plurality of load cells which are implemented at predetermined positions in the touch panel to detect respective components of the stress applied to the touch panel; and a control unit which is connected to the load cells in order to receive magnitudes of the respective components detected by the load cells to thereby calculate the special position and a magnitude of the stress applied to the touch panel based on the respective components and the predetermined positions of the load cells in the touch panel; wherein the control unit receives the respective components detected by the load cells at a plurality of continuous time points in order to thereby calculate the special position on the touch panel applied at each time point to thereby obtain a motion trace applied to the touch panel, and the control unit comprises a multiplexer connected to the load cells, an analog-to-digital converter connected to the multiplexer, and a central processing unit (CPU) connected to the analog-to-digital converter, and wherein the respective components of the stress detected by the load cells are sent through the multiplexer to the analog-to-digital converter to thereby convert into digital signals which are further sent to the CPU to calculate the magnitude, the special position and a motion speed of the stress.
