Combined writing instrument and digital documentor apparatus and method of use
First Claim
1. A handheld, self-contained, communication device that is used to create a written document and to create a digital copy of said document comprising, a writing means, and a position-sensing means that functions by capturing and comparing serial images of the surface imperfections on the document surface, comprising an imaging means to capture images of the imperfections on the document surface, an illumination means to highlight imperfections on the document surface a microprocessor means to compare the serial images of the document surface for measuring positional change of the device, a data storage means for input and/or output from the microprocessor means, and an energy means to power the illumination, imaging, memory, and microprocessor means.

Abstract
A device and method is disclosed for the contemporaneous creation of a digital copy of a written document using a self-contained, hand-held communications device. The self-contained device functions as a writing device and as a digital documenter. It allows for maintenance of position sense within a document thus enabling the user to write cursive, print, draw, write mathematical formulas, draw symbols, punctuate, edit and the like. The invention discloses a self-contained apparatus and method for determining position sense without reliance on special paper, pads, or attachments to the document. The system provides position sense during writing by quantitative comparative analysis of serial images of the surface imperfections of the document. Character generation is discriminated from noncharacter-generating positional changes such as spacing between words. Encryption of data output from the device provides privacy. Encryption and attachment of the device'"'"'s unique identifying code to a digital copy of a document created by the device provides for confirmation of the source. Uses of the device include short text messaging for cell phones, email composition, note taking in business and education, medical records, and electronic commerce. The imaging system can also be used to read barcodes on documents, allowing for applications to inventory control. Transmission of the digital copy of the document can be through a wired or wireless connection to external digital devices such as cellular phone, personal digital assistant, netpliance, or computer.

- 12. A method for producing a digital copy of a written document by using a self-contained pen device that records digitally the position of said device in a document by using a microprocessor to analyze serial images captured by a camera of the document'"'"'s surface and then transmitting said digital document to an external digital device, wherein a loss of position sense of said device within a document is communicated to the user by an audio or light signal from said device.
- 15. A method of producing a digital copy of a written document by using a self-contained pen device that records digitally the position of said device in a document by using a microprocessor to analyze serial images captured by a camera of the document'"'"'s surface and then transmitting said digital document to an external digital device, wherein a loss of position sense within a document is regained by positioning the pen device at the last point of character generation in said document and then signaling to the device by a predetermined manipulation such as double depressing the writing tip that the device is at a specific location within the document.
