Abstract: An electronic pen having a retractable nib for interacting with a surface. The pen comprises a slidably movable cartridge having a nib for contacting the surface, a retraction mechanism for retracting the cartridge, an actuator coupled to the retraction mechanism, a force sensor providing a reaction to an axial force transmitted from the cartridge, and a processor configured for generating force data indicative of a force detected by the force sensor. The retraction mechanism comprises a barrel for receiving the cartridge, which is adapted for seating the cartridge in either an extended position or a retracted position, whereby the axial force from the cartridge is transmitted to the barrel in the extended position. A biasing mechanism biases the cartridge towards the extended or retracted positions.

Abstract: A method is described for positioning an image sensor at a point of best focus for a lens. The lens has an optical axis and the image sensor is moved to a plurality of positions along the optical axis. The image sensor captures an image of a target image at each of the plurality of positions through the lens. A measure of blur in the image captured is derived at each of the plurality of positions from pixel data output from the image sensor. A relationship is derived between blur and position of the image sensor along the optical axis. The image sensor is then moved to a position on the optical axis that the relationship indicates as the point of best focus where the image sensor is fixedly secured relative to the lens.
