Latest Patents

Chien-Ming Li holds a patent for a composite function keyboard circuit. This invention includes a first matrix circuit, a first bias resistor group, a second matrix circuit, a second bias resistor group, and a controller. Each switch unit in the first matrix circuit is an ink-type force sensing switch. The resistance of the ink-type force sensing switch varies according to the pressing mode of a keypress action. An electrical connection path is formed between the ink-type force sensing switch and the corresponding bias resistor of the second bias resistor group. When the ink-type force sensing switch is electrically conductive, a divided sensing voltage is generated by the electrical connection path. The controller then generates a corresponding key control instruction based on the level of the divided sensing voltage. Furthermore, the cooperation of the first matrix circuit and the first bias resistor group achieves a ghost key preventing function.
