Title (EN) AUTONOMOUS LOW-POWER VOICE COIL MOTOR PARKING
(FR) MISE AU REPOS AUTONOME DE MOTEUR À BOBINE MOBILE BASSE PUISSANCE
Abstract:
(EN) A camera module includes an optics assembly, an actuator module, and detection circuitry for preventing the optics assembly from colliding with a mechanical stop due to physical impacts and disturbances. The actuator module includes a magnet and a coil. The detection circuitry detects an induced current caused by movement of the coil with respect to the magnet. The direction of the detected induced current indicates movement of the optics assembly in a particular direction along an optical axis. The detection circuitry provides a current to the coil to cause the optics assembly to move toward a particular position or direction. In some cases, the provided current may cause the optics assembly to move in a direction opposite of the movement that caused the induced current.
(FR) L'invention concerne un module de caméra qui comprend un ensemble optique, un module d'actionneur et un ensemble de circuits de détection permettant d'empêcher l'ensemble optique d'entrer en collision avec une butée mécanique due aux impacts physiques et aux perturbations. Le module d'actionneur comprend un aimant et une bobine. L'ensemble de circuits de détection détecte un courant induit provoqué par le mouvement de la bobine par rapport à l'aimant. La direction du courant induit détecté indique le mouvement de l'ensemble optique dans une direction particulière le long d'un axe optique. L'ensemble de circuits de détection fournit un courant à la bobine pour amener l'ensemble optique à se déplacer vers une position ou une direction particulière. Dans certains cas, le courant fourni peut amener l'ensemble optique à se déplacer dans une direction opposée au mouvement qui a provoqué le courant induit.
