  • Computer with security function and method therefor
    Patent number: 7008456
    Abstract: A technique for prohibiting access to a computer having a security function when a security device is illegally removed from the computer. The security device is a hardware component that constitutes a part of a security function for a computer. When the security device is illegally removed from the computer, access to the computer is prohibited. Data indicating that the security device is attached to the computer are stored in a nonvolatile memory. Then, when a specific event, such as a power-ON event, is used as a trigger, the procedure for prohibiting the access to the computer is initiated. Following this, based on the data stored in the memory, it is detected that the security device was once attached to the computer and that it has now been removed. If currently the security device is not attached to the computer, although it was attached before, the access to the computer is prohibited.

  • Method for prohibiting unauthorized access in a non-contacting data carrier system
    Patent number: 6823459
    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.

  • Power generating mechanism that has a duct, heat pipe, or heat sink to efficiently diffuse heat generated by a heat
    Patent number: 6799282
    Abstract: In a power generating mechanism, a heat sink is mounted on a CPU of a notebook PC to diffuse heat generated by the CPU. A Seebeck element module is mounted in the heat sink to cause a large difference in temperature based on heat emitted from the heat sink and ventilation carried out by a fan unit. Electromotive force obtained from the Seebeck element module is used to drive selected components of the notebook PC.

  • computer in which an optional unit is installable
    Patent number: 6766402
    Abstract: The present invention is directed to a computer in which an optional unit such as a unit including a wireless LAN adapter is installable. The computer including at least a computer body, a display, and a keyboard. The invention is also directed to a note book computer 2, which includes a computer body with a keyboard, and a display workable as a lid being opened and closed free with the computer body. In these computers with an optional unit 14, the optional unit is detachably attached to the top of the display, or the optional unit is detachably attached to a portion of the display, the portion being at a side of the display when the lid is closed and being at a top of the display when the lid is opened.
