    • A modified hybrid Hall effect device is provided which is the combination of a conventional Hall effect device and a second Hall effect device having a Hall plate coupled to a ferromagnetic layer. The hybrid Hall effect device can be used to determine the independent magnetic field vector components comprising a vector magnetic field, such as for determining the x and the z components of a magnetic field, or for measuring the total magnitude of a vector magnetic field of any orientation. The modified Hall Effect device can be adapted for use as a magnetic field sensor for the detection of macroscopic objects that have associated magnetic fields, or for microscopic objects that have been tagged by microscopic magnetic particles. In one specific form, a plurality of hybrid Hall devices are electrically connected together to form an array in which a plurality of rows of hybrid Hall devices are electrically coupled to each other along a current axis, and the array is used for the detection of microscopic objects.
    • 提供了一种改进的混合霍尔效应装置,它是常规霍尔效应装置和具有耦合到铁磁层的霍尔板的第二霍尔效应装置的组合。 可以使用混合霍尔效应装置来确定包括矢量磁场的独立磁场矢量分量,例如用于确定磁场的x和z分量,或用于测量任意的矢量磁场的总大小 方向。 修改的霍尔效应装置可以适用于用于检测具有相关磁场的宏观物体的磁场传感器,或用于由微观磁性颗粒标记的微观物体。 在一个具体形式中,多个混合霍尔器件电连接在一起以形成阵列,其中多行混合霍尔器件沿着电流轴彼此电耦合,并且阵列用于检测微观 对象

    • A heat exchanger including a first header, a second header, and a third header. The third header includes a first plate including a generally planar face and a second plate including a generally planar face parallel to the planar face of the first plate and joined to the planar face of the first plate. The second plate includes an arcuate recess that extends from the planar face of the second plate to at least partially define a flow conduit between a first tube and a second tube. The arcuate recess has a radius of curvature measured from an axis generally parallel to the planar faces of the first and the second plates, and the axis is located within a first plane generally parallel to and midway between first and second opposing flat broad sides of the first tube and the second tube.

    • Methods and apparatus are provided to monitor and analyze activity occurring on a networked computer system. In some embodiments, a method is provided for capturing, in a data structure, at least a portion of a notification describing a network event provided by a node on a computer network, identifying a data element (e.g., an IP address of the node) within the notification, and updating an index and/or summary based on the data element. The data structure may be stored in a file system maintained on a site, and sites may exchange information related to the notification data stored on each. In some embodiments, a query which is issued to a site may be processed using data transferred from other sites, and/or may be split into one or more additional queries which may be transmitted for processing to other sites.
