Pen cartridge that transmits acceleration signal for recreating handwritten signatures and communications
First Claim
1. An ink cartridge for a pen comprising:
- a cartridge having a writing tip;
an ink reservoir contained within the cartridge and communicating with the writing tip for allowing ink transfer from the ink reservoir through the writing tip;
a microelectromechanical (MEMS) accelerometer sensor mounted within the cartridge in a position for generating an acceleration signal indicative of movement of said writing tip; and
a transmitter operatively connected to said microelectromechanical (MEMS) accelerometer sensor for receiving the acceleration signal from said microelectromechanical (MEMS) accelerometer sensor and transmitting the acceleration signal to a remote processor where the acceleration signal is processed for recreating handwritten signatures and communications.

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.
