Abstract
A dual mode apparatus for writing on paper, inputting information to a host electronic device, and/or controlling applications on a host electronic device. The apparatus is preferably constructed and arranged as a combination pen and active stylus that includes a pen refill cartridge and an active stylus module. The pen refill cartridge comprises a body configured for storing ink and a ball-point assembly for dispensing the ink on a writing surface or physical media. The active stylus module is configured to transmit signals to the ball-point assembly of the pen refill cartridge. The ball-point assembly may include an antenna, optical transducer or ultrasonic transducer. In one expedient, the signals may be radio signals characterizing a force applied to the ball-point assembly, the level of a battery or the level of ink in the pen refill cartridge.
