  • Patent number: 9519036
    Abstract: Provided is a magnetic sensor for detecting a magnetic field. The magnetic sensor includes a magnetic layer of a closed loop shape; a pair of current terminals which face each other contacting with the closed loop and through which current is input/output; and a pair of voltage terminals which face each other contacting with the closed loop and from which output voltage is detected. Both an anisotropic magnetoresistance effect (AME) and a planar Hall effect (PHE) contribute to the output voltage and a hysteresis of the output voltage is eliminated by exchange coupling of a ferromagnetic layer by a ferromagnetic-antiferromagnetic layer structure and a ferromagnetic-metal-antiferromagnetic layer structure. Accordingly, it is possible to minimize a hysteresis due to a demagnetization factor of the closed loop, stabilize the output voltage of the magnetic sensor and enhance sensitivity.

  • Patent number: 8719916
    Abstract: The present invention periodically monitors the amount of packets flowing into a packet inspection apparatus, i.e., a load level, and compares the load level with a predetermined upper or lower limit value. Accordingly, the present invention blocks some of the packets or passes along some of the packets through the packet inspection apparatus when the load level exceeds a certain level, and thus the load controlling method and apparatus guarantees continuous operation of the packet inspection apparatus even in an overloaded state. In addition, the load controlling method and apparatus according to the present invention effectively selects packets to be blocked or passed without departing from the original functions of the packet inspection apparatus. The load controlling method and apparatus is configured simply so as not to additionally induce a load in the process of selection, and the load controlling apparatus selectively operates only in an overloaded state.
