Abstract
An ink cartridge for a pen includes a cartridge having a writing tip. An ink reservoir is contained within the ink cartridge and communicates with the writing tip for allowing ink transfer from the ink reservoir through the writing tip. A microelectromechanical (MEMS) accelerometer sensor is mounted within the cartridge in a position for generating an acceleration signal indicative of movement of the writing tip. A transmitter is operatively connected to the microelectromechanical (MEMS) accelerometer sensor and receives any acceleration signals generated from the microelectromechanical (MEMS) accelerometer sensor and transmits any acceleration signals to a remote processor, such as a Personal Digital Assistant (PDA) or a personal computer where any acceleration signals are processed for recreating handwritten signals and communications.
