Collapsible structure for optical navigation system

摘要

A system for optical navigation includes an optical navigation sensor integrated circuit (IC) configured to generate image information for use in navigation sensing and a collapsible structure which sets the distance between the optical navigation sensor IC and a navigation surface and which can be expanded or collapsed as needed. The collapsible structure includes a collapse system configured to allow the collapsible structure to be in an expanded state or a collapsed state. The collapse structure has a smaller profile dimension in the collapsed state than in the expanded state. The collapsible structure is placed in the expanded state for navigation sensing and in the collapsed state for storage and/or charging.
