Abstract: A wireless beam-pen pointing device is proposed, which is designed for use with a computer unit, a presentation screen, and a beam pen. The presentation screen is coupled with a beam-spot position detector which is capable of detecting the beam-spot position where the light beam strikes on the presentation screen and transfer the beam-spot position data to the notebook computer. In response, the notebook computer will move the cursor to the detected beam-spot position. The beam pen is capable of emitting a light beam, such as a laser beam, which allows the speaker to point the light beam at a particular object displayed on the presentation screen that is currently being mentioned in the speaker's speech. The cursor movement is under control by the light beam, so that the cursor will be moved to the location currently pointed by the light beam.

Abstract: A shared input/output network management system is proposed, which allows a group of I/O-unequipped computer units, such as a group of servers, to share one single set of I/O devices, including keyboard, monitor, and pointing device, for the purpose of allowing the user to perform management tasks, such as system updates, file maintenance, and hardware/software testing, on these servers through the single set of I/O devices. The proposed shared input/output network management system is characterized by the use of USB (Universal Serial Bus) communication interface, rather than a keyboard/video/mouse (KVM) switch, for connecting all the servers in the server group to a notebook computer running a server group management program, whereby management tasks can be carried out through the I/O devices of the notebook computer and the server group management program running on the notebook computer.
