An identification system includes several sheets formed of digital paper each having a unique identifier on a writing surface thereof. Each digital paper may have a form printed on the writing surface. Data representing the form and the location thereof relative to the writing surface is stored in a computer. A digital pen connectable to the computer is compatible with the digital paper for recording pen strokes made by the digital pen and the location of the pen strokes relative to the writing surface. The digital pen includes an ink dispensing tip for marking the writing surface according to the pen strokes. The computer is connectable to the digital pen for retrieving and storing the data representing the pen strokes for each sheet. Upon completion of a form, the computer compares the data representing the pen strokes with the form data and determines the user input to the form.

One embodiment of the present invention sets forth a technique for providing an end user with a spatially-aware projector combined with a spatially-aware digital pen for use in a design environment. Paper documents are augmented to allow a user to access additional information and computational tools through projected interfaces. Virtual ink may be managed in single and multi-user environments to enhance collaboration and data management. The spatially-aware projector pen provides end-users with dynamic visual feedback and improved interaction capabilities.

Using solar energy as power supply, the digital card-reading manager in not contacted type is an exchanging intermediate device. The card-reading manager demodulates the received radio frequency wave so as to obtain information, and then stores the information in memory. Through blue teeth, infrared communication, USB interface, 1394 interface, the said information is transferred to PC, personal data processor or mobile phone or handset. The invention includes RFID digital business card, RFID digital card-reading manager. The card includes a microprocessor chip powered by solar energy. The said manager includes a microprocessor possessing function of send receive in use for reading information of dada stored in the business card.

The invention discloses a digital electronic pen which is used for writing on a piece of ordinary digital paper and recognizing the writing. The digital electronic pen comprises an ordinary writing pen, a writing picking-up camera (1) and a core circuit; the core circuit is arranged in the ordinary writing pen; the ordinary writing pen is internally provided with a refill used for finishing ordinary writing; the core circuit comprises a microprocessor (2), a memory (3) and a USB transceiver (4); the output end of the writing picking-up camera (1) is connected with the microprocessor (2); the microprocessor (2) is connected with the memory (3) through an internal bus; and the microprocessor (2) is also connected with the USB transceiver (4). When the digital electronic pen is used for writing and leaves the ordinary ink writing, the microprocessor can obtain the writing data according to the information picked up by the writing picking-up camera and stores the writing data in the memory, and the USB transceiver can be connected with a computer to transmit the writing data into the computer to be stored and read. The digital electronic pen disclosed by the invention has the characteristics of being convenient to use and safe and reliable.

The present invention provides a paper-based meeting service management tool for meeting support functions. The paper-based tool includes a digital pen that can be used to make strokes which can be transmitted from the digital pen to services that provide the meeting support functions. The paper-based tool also includes digital paper that has an underlying image pattern. The digital pen can locate itself on the digital paper by recognizing underlying dot patterns and transmitting the location information to a computer through a Bluetooth connection.

The invention relates to a digital paper marking method based on paper and pen improvement. The method comprises the steps of acquiring an electronic teaching aid test paper file by a first terminal;generating a dot matrix teaching aid electronic file; cutting the dot matrix teaching aid electronic file according to the area of the test questions to obtain a plurality of correction units; one correction unit is a form item; the form item has a form item attribute; performing attribute extension on the form item attributes; wherein the attribute extension comprises setting a standard score anda standard answer of each test question; storing form item attributes for attribute extension; sending the form item attribute, the form item attribute with the expanded attribute and the dot matrixteaching aid electronic file to a server; and determining a corresponding correction unit by the server according to the pen point track information, sent by the data acquisition device, on the dot matrix teaching aid paper file after the question is answered by the first user, and then obtaining the score of the test question corresponding to the correction unit. Therefore, the correction resultof each question on the homework or test paper of the student is obtained, and the score of the student is automatically counted.

A label on an electronic product may be written electronically and maintains the last display state when power is removed from the label. There are many different types of digital paper and electronic paper known in the art that would be suitable for use as such labels. The label includes multiple defined regions that may be independently written, with one of the regions defined to display failure information for the electronic product. In one implementation, the failure information is available on the electronic product itself. In another implementation, the failure information includes information received from a source external to the electronic product. The display of failure information on the label may be in human-readable and/or machine-readable form. The result is a label on an electronic product that provides reliable information regarding a failure of the electronic product.

The invention relates to the technical field of sublimation transfer printing and discloses instant dry type sublimation transfer digital paper. The instant dry type sublimation transfer digital paper comprises perforated PP paper, a water absorbing and permeable layer, a porous layer and a surface channel layer which are sequentially arranged from bottom to top; the porous layer is made of interpenetrating network resin formed by crosslinking of cellulose or sodium carboxymethylcellulose or starch and modified cationic polyacrylamide, or formed by crosslinking of polyacrylamide or cellulose or sodium carboxymethylcellulose and modified cationic starch; on one hand, the interpenetrating network resin can swell to 'catch' a dye for quick ink absorption, and on the other hand, components of the resin are adjusted and the network density is controlled to improve the water permeability, so that water molecules can quickly enter the water absorbing and permeable layer; and the perforated PP paper has excellent flexibility and mechanical strength and is stable in size in the printing process, so that the problem of shrinkage, caused by weather, of the conventional paper base material is solved. The instant dry type sublimation transfer digital PP paper has the characteristics of being instant in drying, quick in ink absorption, good in size stability and low in cost, and can meet the requirements for quick printing and efficient manufacturing at present.
