Abstract: PROBLEM TO BE SOLVED: To provide a superior power supply system for electric/electronic apparatuses, such as a notebook computer and its extention unit which can be coupled/decoupled with/from each other. SOLUTION: When an external DC power is inputted only to a DC-inlet, an FET switch is in a closed state, and the power supplied to the DC-inlet A is supplied to both DC-DC converters A and B. On the other hand, when external DC powers are inputted to both DC-inlets A and B, the FET switch is opened, and the power supplied to the DC-inlet A is supplied to the DC-DC converter A, and the power supplied to the DC-inlet B is supplied to the DC-DC converter B. A user may attach adaptor/adaptors to the DC-inlet A only or to both DC-inlets A and B according to a system construction, for instance the types of apparatuses attached to open slots.

Abstract: PURPOSE: To improve operability by electrically connecting a signal which can actively be inserted/extracted with a portable computer among signals and electrically separating and connecting the signal which cannot actively be inserted/extracted with the portable computer. CONSTITUTION: A sub-bus separation device 32 electrically connects the signal which can actively be inserted/extracted with the portable computer 50 among more than one signals and a main bus separation device 31 can electrically separate and connect the signal which cannot actively be inserted/extracted to the portable computer 50. Even if all the signals can mechanically and collectively be connected, the signal which can actively be inserted/extracted is electrically connected and a user can immediately use it. The signal which cannot actively be inserted/extracted is in an electrically separated state and the destruction of a system can be prevented. Consequently, operability can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive extended unit having a security function against WOL under a multi-user environment where one extended unit is shared by many and unspecified notebook PCs. SOLUTION: This extended unit 200 is provided with an LAN adapter with WOL function for LAN connection. Power is always fed to the LAN adapter 300 by an auxiliary power source 370 and it asserts a WOL signal in response to the reception of a wake-up packet via LAN. The extended unit 200 is provided with a WOL state register and a logic circuit. Thus, network security is provided for an information processing system. An information processing system-side can give an instruction for permitting or inhibiting WOL by writing a prescribed value in the WOL state register. When the logic circuit receives the WOL signal from the LAN adapter, it refers to the WOL state register. When wake-up is permitted, power supply is instructed to the notebook PC 100, and the WOL signal is ignored and WOL is not executed when wake-up is inhibited.

Abstract: PROBLEM TO BE SOLVED: To provide a system where DMA transfer is correctly executed even when DMA controllers exist in a self system and also in a docking station by adding the respective specified first and second DAM controllers and a control circuit. SOLUTION: This system includes a first and second DMA controllers where prescribed IO addresses are respectively assigned and the control circuit which responds to CPU 11 in place of the first and second DMA controllers when IO access to the prescribed IO address occurs. A bridge circuit 20 is constituted by adding the first DMA controller, an interrupting controller and a programmable interval timer. The bridge circuit 51 has almost the same configuration as the bridge circuit 20 at a PC side and also incorporates the second DMA controller for managing a DMA request and an interruption request which are generated on a secondary ISM bus 53 and an interruption controller.

Abstract: PROBLEM TO BE SOLVED: To reduce waste when testing operations of a plurality of releases of software using two or more pieces of test data.SOLUTION: In a test execution device 10, when a test execution part 14 tests the latest release of the software using two or more pieces of test data, a test result analysis part 15 groups the two or more pieces of test data on the basis of the test result and a test result history of the releases until then stored in a test result storage part 16, and calculates a test result stability index and a module stability index for each group. When the test result stability index and the module stability index of a certain group exceed thresholds, a list preparation part 18 prepares a list in which the test data of the group is aggregated. The test execution part 14 tests the software using the test data in the list prepared by the list preparation part 18 among the test data stored in the test data storage part 11.

Abstract: PROBLEM TO BE SOLVED: To manage the existence of an information processing system by forming the installation message of identifier data of an extension unit and an information processing system and transmitting the installation message to a management server. SOLUTION: When note PC 100 being an information processing system is installed in an extension unit 200, sub-CPU 40 reads UUID (identifier data) of note PC 100 from EEPROM 39 and writes UUID into EEPROM 916 via SM buses 38 and 238. Dock CPU 211 writes UUID of the extension unit 200 held in EEPROM 215 into AOL-ASIC (IC for special purpose) 914, issues a prescribed message transmission processing command to AOL-ASIC 914 via the SM bus 238, forms the installation message and transmits it to a management server via a network 400.
