Electronic pen and method for recording of handwritten information
First Claim
2. An electronic pen for recording of handwritten or hand-drawn information, comprising:
- a memory; and
a control unit configured to register pen movements across at least one base during a plurality of unique working sessions formed sequentially in time, and to store the registered pen movements as a plurality of digital pen strokes in the memory;
wherein the control unit is further configured todetect a current working session of the pen for each digital pen stroke in the plurality of digital pen strokes, wherein the control unit is operable to detect the same current working session for more than one of the digital pen strokes; and
store session information in the memory identifying the current working session for said each digital pen stroke.

Abstract
An electronic pen for recording of handwritten or hand-drawn information has a control unit and a memory. The control unit registers pen movements across at least one base, stores a plurality of digital pen strokes in the memory as a function of said movements, and supplies a set of the digital pen strokes for processing. The digital pen strokes include a first type, which is processed as graphical information constituting the information to be recorded, and a second type, which is processed as instructions for the processing of digital pen strokes of the first type. The electronic pen also has session-determining means adapted to detect a current working session of the pen. The control unit indicates, for the processing of the set of digital pen strokes, the working session during which the respective digital pen strokes have been input.
