Latest Patents
Ohlgren holds a patent for a "Control system for optical zoom and focus for miniature camera modules." This invention describes a method for driving an optical lens system that includes a first and a second group of optical lenses. These lenses are movable along a linear path parallel to an optical axis by respective motors. The system reads the present position of the lens groups and communicates this information to a drive unit. The drive unit receives commands for the desired optical zoom degree and focusing distance, deducing the requested positions of the groups based on predetermined lens positioning data. The motors are then driven to move the groups to their respective positions, utilizing voltage signals over electromechanical materials.
