Patent number: 10802589Abstract: A method of driving an actuator using a shape memory alloy is provided. An impact-driven actuator is activated by a pulse voltage generated by an action of a transistor. A keyboard outputs a key event at the timing of an input operation. A stress monitoring unit calculates a stress amount of an impact-driven actuator based on parameters of a key event and a pulse voltage. A stress adjustment unit changes the parameter of the pulse voltage when the stress amount reaches a permissible value. The parameter may be a wave crest value or a pulse width of the pulse voltage. The stress adjustment section is also able to stop the action of the impact-driven actuator in response to a key event corresponding to a break code.Type: GrantFiled: May 25, 2017Date of Patent: October 13, 2020Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Mitsuhiro Yamazaki, Kenji Yanai, Fusanobu Nakamura, Yasushi Tsukamoto
