To determine the number of elements (A, B) and common elements (C) in the control panel descriptions provided, we need to analyze the content based on the unique identifiers given for buttons and knobs in each description. According to the definitions:
**First Description:**
1. Button with 'A lock with a water drop' icon
2. Button with 'A wrench' icon
3. Button with 'A square with a horizontal line in the middle' icon
- Total elements (buttons/knobs) in the first description: **3**
**Second Description:**
1. Button '标识(杯子图标)'
2. Button '标识(温度计图标)'
3. Button '标识(锁图标)'
- Total elements (buttons/knobs) in the second description: **3**
**Common Elements:**
To find common elements or overlap, we consider the uniqueness of button/knob characteristics in each description. Given the differences in icon descriptions (both languages and imagery), there are no common elements in terms of specific buttons or knobs as described.
- Total common elements: **0**
Thus, the output indication of how many elements are in the first and second descriptions, along with the number of elements present in both, is:
```
[3, 3, 0]
```
