20090235048 | INFORMATION PROCESSING APPARATUS, SIGNAL TRANSMISSION METHOD, AND BRIDGE - Introduced is an end-point bridge that relays an end point—formed by an external bus in a device tree managed by a first processor unit and an end point formed by an external bus in a device tree managed by a second processor unit. A conversion unit in the end-point bridge replaces a requestor ID contained in an access request packet, for example, which has reached the end point, to the ID of the end point from the ID of a host bridge. The ID of the host bridge is stored in a memory in a manner that the ID of the host bridge is associated with a tag of the packet, and is used to return the requestor ID when a response packet to the request reaches the end point. | 09-17-2009 |
20090311584 | ELECTRIC STORAGE DEVICE - An electric storage device is provided with a battery cell, a collector foil having a first metal plate and a second metal plate laminated together, and a voltmeter for measuring potential difference between the first metal plate and the second metal plate.

20100070675 | BRIDGE, INFORMATION PROCESSING SYSTEM, AND ACCESS CONTROL METHOD - Transparency of resources is provided and ordering in an access is guaranteed between nodes on a computer network. In an information processing system in which a plurality of processor units are connected to each other by a switch, a global address space is introduced into which effective addresses of the processor units are mapped and which is shared by the plurality of processor units. In response to an access request packet issued by a processor unit and designating an effective address of a target node, a bridge for routing an input and output bus of a processor unit to an input and output bus of the switch converts the effective address of the target node into a global address by appending to the packet a node identification number identifying the target node, and outputs the access request packet designating the global address to the switch. After an access request packet for a write operation is output, the bridge confirms whether the write operation is completed in a target node. | 03-18-2010 |
