Electromagnetic scroll wheel control for peripheral devices
The granted patent US12032760B2 describes a sophisticated peripheral device featuring a scroll wheel that integrates advanced magnetic technology for enhanced user interaction. The device comprises a body and a rotatable scroll wheel, which includes a ferromagnetic rotor with an annular shape and an open interior. This rotor is equipped with a first set of teeth that align with a second set of teeth on a stator positioned within the rotor. The stator contains at least one permanent magnet and multiple electro-permanent magnets, each housed within a conductive coil. A position sensor detects the angular position of the rotor, while control circuitry manages the delivery of current pulses to the electro-permanent magnets, enabling the scroll wheel to rotate based on user input and predefined speed ranges.
Additionally, the patent outlines various functionalities of the control circuitry, including the ability to adjust the scroll wheel's speed based on user input and to stop the rotation when a screen's end is reached. The position sensor operates at a high sampling rate of at least 10 kHz, ensuring precise tracking of the scroll wheel's movement. The device also features an electric motor with two portions, one connected to the scroll wheel and the other to the body, allowing for dynamic control over the scroll wheel's acceleration, deceleration, and speed relative to external inputs. This innovative design aims to enhance user experience by providing responsive and adaptable scrolling capabilities, making it suitable for various computer peripheral applications.
