    • Low cost apparatus and methods of detecting arc faults for better discriminating electrical events. The arc fault detection apparatus includes a current sensor, a di/dt input sense circuit, a dv/dt input sense circuit, and a processing unit. The current sensor monitors a power line current, and provides high frequency components of the power line current to the di/dt input sense circuit. The dv/dt input sense circuit monitors a power line voltage. The di/dt and dv/dt input sense circuits generate signals carrying information relating to changes in the power line current and the power line voltage, respectively. The processing unit analyzes these changes in the power line current and the power line voltage to discriminate detected electrical arcing events from nuisance loads with increased accuracy.

    • An electrical signal processing device includes at least one thin film flux generator and at least one thin film magnetic sensor. Each flux generator includes at least one conductive induction line that is connected to at least one lead of a pair of input leads, and a yoke that surrounds the conductive induction line. The yoke has at least one pair of pole tips, and a gap is disposed between the end surfaces of each pair of pole tips. A magnetic sensor is disposed in the gap, and a pair of output leads is connected to the sensor. An alternative embodiment may include two or more conductive induction lines that are connected to respective separate pairs of input leads. Alternatively, two or more conductive induction lines may connect to one another to form an induction coil. The flux generator and magnetic sensor are preferably formed on a single substrate to create an integrated device.
    • 电信号处理装置包括至少一个薄膜通量发生器和至少一个薄膜磁传感器。 每个通量发生器包括连接到一对输入引线的至少一个引线的至少一个导电感应线和围绕导电感应线的磁轭。 轭具有至少一对极尖,并且间隙设置在每对极尖的端面之间。 磁传感器设置在间隙中,并且一对输出引线连接到传感器。 替代实施例可以包括连接到各个分立的输入引线对的两个或多个导电感应线。 或者,两个或更多个导电感应线可以彼此连接以形成感应线圈。 通量发生器和磁传感器优选地形成在单个基板上以形成集成装置。
