Latest Patents

One of his latest patents is a stylus pen featuring an automatic consecutive tapping function. This innovative stylus pen includes a pen unit, a switch, and a control unit. The pen unit consists of a tip and a shaft connected to the tip. The control unit can switch between a default mode and an alternative mode based on the operation of the switch. In the default mode, the control unit emits a default-mode wave of a specific frequency to the shaft. Conversely, in the alternative mode, the control unit emits an alternative-mode wave to the shaft in a pulsating pattern. This pulsating pattern includes a working period where the control unit emits the alternative-mode wave and a non-working period where it stops emitting the wave.

Another significant patent is for a touchpad device designed to be operated using a stylus pen. This device comprises a touchpad and a controller that are interconnected. The controller connects to an electronic device with a display panel and operates in a stylus-pen mode, presenting a handwriting area on the display. When the distance between the stylus pen and the touchpad is less than a preset pen-hover distance but not zero, the controller enters a hover-move sub-mode. In this mode, the controller outputs a control signal that enables the electronic device to present a moving cursor in the handwriting area without displaying a trace of the cursor.
