Abstract: A non-copyable data storage disk (NCDisk) that may be used in a secure data storage system. Stored data items on the NCDisk may only be used through the data storage system, and cannot be copied to and used by any other devices. Digital data written to the NCDisk is automatically converted to a new format by the NCDisk itself before being stored on it. Similarly, when reading a data item out from the NCDisk, the NCDisk itself automatically converts the stored data item to a new data format that a reading device can recognize. Data conversion does not involve the computer operating system. The data conversion unit may include a chipset level 2 secure key management module that generates and manages the keys used for the data conversion.

Abstract: The present invention, in one or more embodiments, provides an apparatus comprising an optical transmitter and an optical receiver located in a pen shaped housing. The apparatus may be further comprised of a processor. The optical transmitter may send out optical signals toward a surface and the optical receiver may receive the optical signals reflected off of the surface. The processor may process the optical signals received by the optical receiver to determine the location or movement of the pen shaped housing.

Abstract: A pen-like apparatus is used to rotate a computer mouse ball. The pen-like apparatus may be comprised of a plurality of balls, wherein the rotation of the balls controls the movement of a computer cursor on a computer monitor. A device may be provided for substantially fixing a computer mouse at a location. A device may be provided for rotating a ball of the computer mouse, while the computer mouse is substantially fixed at the location. A computer keyboard is also provided comprising a typing area, an area in which a computer mouse can be fixed in a location, the computer mouse including a ball, and an area which is responsive to the movement of an implement so that the movement of the implement causes movement of the ball of the computer mouse and thereby controls a computer cursor on a computer monitor.
