KEY CONTROL DEVICE AND KEY CONTROL METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17641131 titled 'KEY CONTROL DEVICE AND KEY CONTROL METHOD
Simplified Explanation
The abstract describes a key control device and method that includes an encoder circuit, a first interface extension circuit, and a main control circuit.
- The encoder circuit outputs voltage signals in response to a rotational operation.
- The first interface extension circuit receives the voltage signals and generates an interrupt signal and voltage state transition data.
- The main control circuit determines the rotation direction based on the interrupt signal and voltage state transition data.
Potential Applications:
- Key control systems for electronic locks or security systems.
- Input devices for electronic devices such as keyboards or game controllers.
Problems Solved:
- Provides a reliable and accurate method for determining the rotation direction of a key control device.
- Simplifies the process of generating interrupt signals and voltage state transition data.
Benefits:
- Improved security and accuracy in key control systems.
- Enhanced user experience with input devices.
- Simplified design and implementation of key control devices.
Original Abstract Submitted
A key control device and a key control method are disclosed. The key control device includes: an encoder circuit including a first output terminal and a second output terminal and configured to output a first voltage signal and a second voltage signal through the first output terminal and the second output terminal respectively, under triggering of a rotational operation; a first interface extension circuit configured to receive the first voltage signal and the second voltage signal, and generate an interrupt signal and voltage state transition data in response to the first voltage signal or the second voltage signal output by the encoder circuit; and a main control circuit configured to determine a rotation direction of the rotation operation according to the interrupt signal and the voltage state transition data.
