This disclosure describes apparatus and method for powered pens used in conjunction with inductive proximity sensors. The powered pens and proximity sensors can provide information related to user input with the pen (such as positional information), which makes them very useful in portable applications such as handheld computing devices. The disclosure further describes how pens can communicate with their proximity sensors, and how their proximity sensors can communicate with each other to enable data transmission. The disclosure also describes potential additional pen functionality such as speech recording, security, scanning, and bar code reading.
