Abstract: An apparatus for shielding a sensitive file includes a client computer having various units. An encryption-decryption unit performs a cryptographic operation on the sensitive file with a cryptographic key, which corresponds to the encryption key ID. An encryption key ID is associated with the sensitive file. A key storing unit stores the cryptographic key. A compliance requirements storing unit stores security compliance requirements from the server computer, which define a plurality of compliant operating conditions of the client computer. A security requirements monitoring unit determines whether the client computer complies with the security compliance requirements in response to a file access instruction for the sensitive file by application software, and passes the cryptographic key from the key storing unit to the encryption-decryption unit in response to a determination that the client computer complies with the security compliance requirements.

Abstract: Techniques to manage position information of parts such that, if discrepancy of the parts occurs, the discrepancy can be detected and corrected while the advantages of using the constraint conditions can be offered. In one embodiment, when an input unit receives information of an icon click, a receiving section receives the information of the click, and a saving section saves the position and the angle of geographic data indicating the three-dimensional geometry of the part as absolute-position information calculated with reference to the absolute origin into the storage unit.

Abstract: Embodiments of the invention provide for shielding a sensitive file on a computer that can connect to a server computer via a network. The computer may determine whether it complies with security compliance requirements sent from another computer or not in response to a read instruction or a write instruction of the sensitive file by application software, and encrypt the sensitive file with an encryption key.

Abstract: A modular personal computer of the present invention includes inlet and outlet openings for a cooling air flow, which are provided on a side portion of a housing disposed opposite to a desktop connection device, with the openings being spaced from each other across a central processing unit, and air passages extending between the inlet and outlet openings in an overlapping manner. Static pressure near the outlet opening is reduced by a diffuser. Air inside the modular personal computer is drawn out through the outlet opening to create negative pressure inside the modular personal computer, so that the cooling air flow is introduced from the inlet opening.

Abstract: A modular computer system includes a core unit comprising a processor and a memory; a removable modular accessory; a docking connector for connecting the accessory to the core unit; and one or more subsystems contained within the accessory. The system is partitioned such that any of the cooling, power or input/output subsystems can be disposed within the modular accessory such that these subsystems can be removed from the system by removing the accessory. The core unit by itself is not useful to a user because it lacks power, cooling, or a user interface. The core unit can be connected into any of a variety of accessories and it adapts its functions to the system resources provided by each type of accessory.
