Docking alignment sensor

摘要

A docking station for an electronic device senses the position of the electronic device and provides an electronically-generated feedback signal to a user indicating whether the device and the docking station are in proper alignment for docking. The sensing may optionally be accomplished by electrical contacts or may optionally be accomplished by sensing a magnetic field using a Hall effect sensor. The feedback signal may be visible or may be audible. The feedback signal may provide instructions to the user indicating which direction one of the components should be moved to achieve proper alignment. A simple backstop arrangement may provide proper alignment in one axis, while the feedback signal provides information about the alignment in a second axis, preferably generally orthogonal to the first. The electronic device may be a laptop portable computer.
