  • Tunneling magnetic sensing element including non-magnetic metal layer between magnetic layers
    Patent number: 7787221
    Abstract: A first pinned magnetic sublayer 4a has a multilayered structure including a first insertion subsublayer disposed between a lower ferromagnetic subsublayer and an upper ferromagnetic subsublayer. The first insertion subsublayer has an average thickness exceeding 3 ? and 6 ? or less. This results in an interlayer coupling magnetic field Hin lower than a known art while RA and the rate of resistance change (?R/R) substantially identical to those of the known structure are maintained.

  • System for detecting packetization delay of packets in a network
    Patent number: 7646726
    Abstract: A system is disclosed for detecting packetization delay of packets in a network. The system includes a router to receive at least one packet containing data. A detection system, which is in communication with the router, extracts a codec information and a packet length information from the packet. A management system, which is in communication with the router, receives the codec information and the packet length information and determines packetization delay based on the codec information and the packet length information.
