System for measuring fold angle in foldable devices
The patent US12072741B1 describes a sophisticated system designed to determine the fold angle of foldable devices using a network of electrodes and a processing system. The system operates by first detecting temperatures at various times and obtaining baseline absolute capacitance measurements that correlate with known fold angles. As the temperature changes, the system updates these baseline measurements and uses them to assess the fold angle based on subsequent capacitance readings. The processing system is also capable of detecting external inputs, such as a finger near the device's hinge, which can influence the fold angle calculations by incorporating transcapacitance measurements or pausing updates when necessary.
Additionally, the system includes mechanisms to ensure accurate measurements by distinguishing between capacitance changes due to folding and those caused by other factors, such as temperature drift. It can generate updated baseline capacitance measurements based on detected changes and can apply scaling factors to refine the fold angle determination. The integration of both absolute and transcapacitance measurements allows for a more nuanced understanding of the device's position, enhancing the reliability of the fold angle assessment. Overall, this patent outlines a comprehensive approach to improving the functionality and responsiveness of foldable devices through advanced capacitance measurement techniques.
