Abstract: A diacritic chording system uses a single standard keyboard layout to generate diacritical characters used, for example, by Latin-based languages or languages based on a Roman character set, providing a universal keyboard The key combination required to select a diacritic is consistent, independent of the language the user is typing. The diacritic chording system uses chording to obtain characters modified by diacritics, i.e., diacritical characters. The key combinations in the diacritic chord are chosen in such a way to aid memorization by positional association of the keys or by logic association of the keys within the diacritic chord. The use of a combination of positional association and logical association eliminates conflicts in mapping diacritics for different languages. The diacritic chording system also provides a screen overlay as a mnemonic to illustrate which diacritic chords provide the desired diacritical character.

Abstract: Methods and arrangements are disclosed for secure single sign on to an operating system using only a power-on password. In many embodiments modified BIOS code prompts for, receives and verifies the power-on password. The power-on password is hashed and stored in a Platform Configuration Register of the Trusted Platform Module. In a setup mode, the trusted platform module encrypts the operating system password using the hashed power-on password. In a logon mode, the trusted platform module decrypts the operating system password using the hashed power-on password.

Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to minimize the performance impact on 802.11g clients in the presence of mixed in 802.11g/802.11b traffic by isolating wireless network traffic based on protocol. At least one 802.11g timer is maintained for 802.11g traffic. Request for transfers by 802.11b clients which are blind to 802.11g traffic are delayed until after the expiration of the 802.11g timer. Traffic for 802.11g clients proceeds unimpeded while the 802.11g timer is active. A similar timer is optionally maintained for 802.11b traffic.

Abstract: A method and system are disclosed for substituting an anonymous media access controller (MAC) address for a client computer system's real MAC address in order to disguise an identity of the client computer system when the client computer system is utilizing a network. The client computer system is coupled to a server computer system via the network. A primary storage device is established for storing a MAC address. A MAC address which is stored in the primary storage device is utilized as a network address for the client computer system when the client computer system is utilizing the network. An anonymous MAC address is generated. The anonymous MAC address is not associated with any particular client computer system. The anonymous MAC address is then stored in the primary storage device. The client computer system utilizes the anonymous MAC address as the network address for the client computer system when the client computer system is utilizing the network.

Abstract: To provide a method whereby unauthorized data access by an RFID data processing system is prohibited without any degradation of performance being incurred. An RFID data processing system 30 comprises a CPU 35, a EEPROM 34, communication devices 31 and 32, and power controllers 40 and 41. When an RFID data processing system 30 in the power-ON state that does not have access authorization passes through a portal gate located at the entrance to an unauthorized data access protection area, the portal gate transmits a signal to set ON a tamper bit 44 in the EEPROM 34. When the tamper bit 44 has been set ON, a tamper bit interrupt request signal is output by the EEPROM 34. Upon receiving this signal, the power controllers 40 and 41 power off the RFID data processing system 30.

Abstract: A portable information processor includes a computer main body and a digitizer connected by a flexible hinge defined in a cover. The hinge allows the computer main body and the digitizer to assume different superposed states by means of a flexible separable portion of the cover. In the superposed state of the computer main body and the digitizer, arbitrariness in folding back the separable portion causes runout between the computer main body and the digitizer. In spite of this runout, the superposed state can be accurately detected by means of an optical sensor, including an infrared radiator and an infrared-ray detector, disposed in the computer main body. A flexible reflection member is fixed to a predetermined surface of the separable portion of the leather cover, while assuring a predetermined area. If the computer main body and the digitizer assume a superposed state, light emitted from the infrared radiator is reflected by the flexible reflection member and is incident on the infrared-ray detector.

Abstract: A packet communications network includes a route management system in which routes can be remotely changed by using a simple set command to set a data value in the originating or terminating node of the route. Storage tables in the originating and destination nodes record the route changes and administrative data concerning the route. This administrative data can be retrieved from the originating node by simple get or get-next commands. The administrative data can include the specific specification of the route in links, the time of creation of the route, the route replaced and the reason for initiating the change in route. Together these capabilities permit centralized management of route changes in the entire network from a single manager node, and using only simple set, get and get-next command structures.
