Apparatus for sensing user input

The invention relates to a device for sensing an user input. An apparatus comprising an electronic circuit electrically coupled to a first strain gauge, the electronic circuit configured to: (i) receive a first parameter signal from the analog-to-digital converter in response to user input that interacts with the housing over a location of the first strain gauge, (ii) determine a value for the first parameter signal, (iii) compare the determined value of the first parameter signal to a maximum value associated with the analog-to-digital converter, and (iv) adjust an amplification level of theamplifier in response to comparing the determined value of the first parameter signal to the maximum value associated with the analog-to-digital converter. 本申请涉及用于感测用户输入的设备。一种设备，包括电耦合至第一应变计的电子电路，所述电子电路被配置为：(i)响应于在所述第一应变计的位置上与所述壳体交互的用户输入，从所述模数转换器接收第一参数信号，(ii)确定所述第一参数信号的值，(iii)将所述第一参数信号的所确定的值和与所述模数转换器相关联的最大值相比较，以及(iv)响应于将所述第一参数信号的所确定的值和与所述模数转换器相关联的所述最大值相比较，调整所述放大器的放大水平。
