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. The headings of the various subsections are as follows: 1.1 Background, 1.2 SPIRAL advantages for PDA's, 2.1 Powered Pen, 2.2 Communications (2.2.1 Communication with the Pen, 2.2.2 Communication between PDA's), 2.3 Extra functionality in the Pen (2.3.1 Non-positional ideas, 2.3.2 Scanning), and 2.4 Input device (stand-alone, or when docked with a host).
