Patent number: 7869441Abstract: An input interface segments a variable length packet into plurality of fixed length cells and generates an internal switching information based on the header information of the variable length packet. The input interface transmits the information to a switch and, after that, transmits the cells as the following cells of the information to the switch. The switch performs switching processing to the succeeding cells based on the information. Therefore, the information is not added to the cells. When an input interface starts to transmit cells generated from a packet to its destination output interface through the switch, the switch is reserved until all the cells arrive at the output interfaces.Type: GrantFiled: August 17, 2004Date of Patent: January 11, 2011Assignees: Hitachi, Ltd., Hitachi Information Technology Co., Ltd.Inventors: Kenichi Sakamoto, Nobuhito Matsuyama, Takeshi Aimoto, Noboru Endo, Koji Wakayama, Norihiko Moriwaki

Patent number: 7518998Abstract: In an IP packet communication apparatus, an operation and maintenance function capable of monitoring a transmission path is provided to a layer used to process a packet, which corresponds to an upper layer of an optical network. As one method for applying the operation and maintenance function to the packet layer, in the case of IP over PPP over WDM, an operation/maintenance frame is defined to a PPP frame so as to realize the operation/maintenance function of a PPP connection. In the case that a plurality of connections are multiplexed on the same transmission path, a maintenance frame is conducted in order to operate/manage these connections by being grouped, so that a fault occurring in the optical network is monitored. As another method for applying the operation and maintenance function to the packet layer, an operation/maintenance frame is defined to an IP packet so as to realize an operation and maintenance function of an IP flow.Type: GrantFiled: April 27, 2005Date of Patent: April 14, 2009Assignee: Hitachi, Ltd.Inventors: Kenichi Sakamoto, Noboru Endo, Toshiki Sugawara, Koji Wakayama, Kazuyoshi Hoshino

Patent number: 7463633Abstract: Upon initialization, a VPC is set up between edge nodes. A control processor of each node creates an IP address/VPC mapping table using IP routing information and an address mapping table mapping correspondence between IP addresses and ATM addresses and supplied by a network management system. A gateway assigns a VCC to each packet input to the network. A sending-side edge node inputs the packet to the VPC corresponding to its destination by referring to the IP address/VPC mapping table. A transit node performs packet switching over VP. A receiving-side edge node transfers each packet to the gateway corresponding to its destination. If a series of packets meet a predetermined condition in a given edge node, its control processor sends VCC information to input interfaces of the edge node so that the packets are switched by an ATM switch in the edge node without intervention of the control processor.Type: GrantFiled: June 14, 2001Date of Patent: December 9, 2008Assignee: Hitachi, Ltd.Inventors: Noboru Endo, Akihiko Takase, Hajime Abe, Kazuho Miki

Patent number: 7365452Abstract: A pressure sensor device (1) includes a sensing element (2) for sending an analog signal according to pressure. The pressure sensor device (1) outputs the analog voltage to a microcomputer (20) through an input-output terminal (8). An input-output control circuit (4) monitors the voltage value in the input-output terminal (8). When the voltage of the input-output terminal (8) is set to high by the microcomputer (20) and is dislocated from a predetermined range, the input-output control circuit (4) functionally changes the input-output terminal (8) outputting a detecting signal to a terminal for inputting an external signal from the microcomputer. After the input-output terminal (8) is changed to the terminal for inputting the external signal, a range control circuit (7) fetches an external command signal through the input-output terminal (8) and switches the output characteristics.Type: GrantFiled: October 17, 2003Date of Patent: April 29, 2008Assignee: DENSO CORPORATIONInventors: Noboru Endo, Yasuaki Makino

Patent number: 7345614Abstract: An A/D converter has inverting elements and delay elements alternately disposed in series. Each inverting element receives an analog voltage signal as a power source and converts a pulse signal in an inversion operation time depending on the analog voltage signal. Each delay element delays transmission of the pulse signal. The transmission of the pulse signal is started from a starting inverting element at a start time, and a transit position of the pulse signal is detected at a detection time later than the start time by a predetermined time. A digital value indicating a level of the analog voltage signal is determined from the detected transit position of the pulse signal. Because transmission of the pulse signal is delayed by the delay elements, the transit position depending on the analog voltage signal can be correctly detected.Type: GrantFiled: October 26, 2006Date of Patent: March 18, 2008Assignee: DENSO CORPORATIONInventors: Yasuaki Makino, Noboru Endo, Takamoto Watanabe, Mitsuharu Kato
