20080225019 | Electronic ink pen structure with an immediate charging function - An electronic ink pen structure with an immediate charging function includes a casing, a refill, a light-emitting element, a double-layered capacitor, two conductive pieces, and a repositioning module. The refill is movably disposed in the casing, and has a pen nib on a front side that is exposed outside a front side of the casing. The light-emitting element is disposed in the casing, next to one side of the refill. The double-layered capacitor electrically connects with the light-emitting element. One side of each conductive piece is exposed outside the casing and the other side is disposed in the casing for electrically connecting with a positive side and a negative side of the electrode of the double-layered capacitor. The repositioning module is disposed between the light-emitting element and the double-layered capacitor, and the repositioning module has a magnetic repulsor for making the refill stay in its original position. | 09-18-2008 |
20080291179 | Light Pen Input System and Method, Particularly for Use with Large Area Non-Crt Displays - The invention relates to a light pen input system with a light pen which is adapted to generate at least one scanning light line sweep for scanning a surface such as for example a display screen. The time from starting a scan until a light sensing element placed at a known position detects a scanning light line is measured and processed for determining the coordinates of the pointing position of the light pen. Thus, an “inverse” light pen is provided which may be implemented at low costs and which may be used with non-CRT displays. Furthermore, the system is independent of the display screen size. | 11-27-2008 |

20090115747 | Digital notebook - This invention relates to a digital notebook which comprises a pen, a USB storage unit and paper. The pen is provided with a wireless transmission module. The USB storage unit is provided with a wireless reception module, a processing module and a data storage module, and the USB storage unit is fixed on the paper. When a writing action is conducted by the pen on the paper, the wireless transmission module of the pen continuously transmits signals which are then received by the wireless reception module of the USB storage unit. The signals are stored in the data storage module after they are operationally processed by the processing module. After the digital notebook is connected to a personal computer through the USB port on the USB storage unit, the data written on the paper can be displayed on the personal computer. | 05-07-2009 |
20110069041 | Machine-differentiatable identifiers having a commonly accepted meaning - Embodiments include an article of manufacture, apparatus, device, system, computer-program product, and method. In an embodiment, system is provided that includes at least two machine-differentiatable identifiers, each identifier of the at least two machine-differentiatable identifiers being respectively keyed to a data recipient and associatable with a hand-formed mark on a surface. The system also includes a commonly accepted meaning respectively associated by a group of users with each machine-differentiatable identifier of the at least two machine-differentiatable identifiers. The system may include a surface displaying the at least two machine-differentiatable identifiers. The system may include a surface displaying the at least two machine-differentiatable identifiers and the commonly accepted meaning respectively associated by a group of users with each machine-differentiatable identifier of the at least two machine-differentiatable identifiers. | 03-24-2011 |
20110128258 | Mouse Pen - A mouse pen includes a pen pipe having a touch device with a touch board module and an up-down event module, and the controlling circuit mainly controls a circuit board with a micro processor as well as connects to the battery module, the touch device, and a detective device. While moving the pen pipe, the detective module detects signals on a moving track; thence the touch board module and the up-down event module would affect an auxiliary function and executive command. After processed by a processor, signals are wirelessly transmitted to an outer electronic device for controlling the cursor and other related operations on a screen. | 06-02-2011 |
20150130773 | CRT Light Pen Interface For Flat Panel Displays - A CRT light pen emulating interface with power save and remote access for flat panel displays includes a pen flat panel display that indicates at least one of a user action with a light pen switch or other device and a presence of a light pen emulating object positioned on or proximate to a display surface of the electromagnetic pen flat panel display. A light pen emulating object is positioned proximate to the electromagnetic pen flat panel display. A processor generates a light pen emulation signal comprising position data for the light pen emulating object relative to the display surface of the electromagnetic flat panel display. A light pen CRT electronic interface converts the position data for the light pen emulating object into a corresponding signal that is comparable to a signal generated by a CRT light pen viewing a scanning dot on the CRT screen. | 05-14-2015 |
