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.

摘要： A dual-channel optical navigation system with vertically aligned sensors. The dual-channel optical navigation system includes a circuit board, a contact navigation sensor, and a free-space navigation sensor. The circuit board mechanically supports and electrically connects multiple navigation sensors on opposing sides of the circuit board. The contact navigation sensor is coupled to a first side of the circuit board. The contact navigation sensor generates a contact navigation signal based on contact navigation images of a contact navigation surface approximately adjacent to the dual-channel optical navigation system. The free-space navigation sensor is coupled to a second side of the circuit board. The free-space navigation sensor generates a free-space navigation signal based on free-space navigation images of an operating environment of the dual-channel optical navigation system.

摘要： An apparatus having a coherent light source, an optical sensor, and a controller that can be utilized in optical mice and the like is disclosed. The coherent light source emits coherent light in a cone of angles about an illumination direction. The optical sensor includes an array of photodetectors disposed on a die having a surface substantially perpendicular to the illumination direction. The controller compares first and second images recorded by the optical sensor at different times and determines a displacement indicative of the direction and distance the apparatus has moved between the two different times. A portion of the coherent light source is bonded to the die at a location within the array of photodetectors.
