摘要： A Lorentz force-driven mechanical resonator apparatus that utilizes a high-Q resonant structure as both a mixing device and a high-Q bandpass filter. Specifically, an external time varying, but quasistatic, magnetic field is applied to the resonating device while simultaneously running a time varying electrical current through the device. The resulting Lorentz force (I×B) is proportional to the vector product of the electrical current in the bar (I) and the external magnetic field (B). Integrating such a resonant device with a magnetic field coil produces the functionality of an ideal radio frequency (RF) mixer coupled with a high-Q intermediate frequency (IF) filter. Wide tunability provides the capability to scan, or even step, an array of filters having very narrow bandwidths via a common local oscillator to a desired frequency range.

摘要： Current is sensed in a physically large conductor by a pair of noncontacting, magnetically responsive corrected current sensors. The sensors each have a preferred magnetic sensing axis. A holding arrangement, which may be a printed-circuit board, holds the two current sensors with their axes spaced apart and parallel, to thereby define a sensing plane. The holding arrangement is placed near the conductor in which current is to be sensed, with the sensing plane parallel to a tangent to outer surface of the conductor. The current in the conductor is represented by the sum of the signals of the sensors. In the case of alternating current and sensors responsive to the absolute value of magnetic field, the summing includes subtraction.

摘要： A Hall effect sensor or device may be used in a variety of embodiments, such as measuring current within an associated conductor by helping to measure flux density within a gap of a ferromagnetic power meter core, such as in a power meter. A high linearity interface for a Hall effect device is provided for minimizing offset effects without using complicated electronic circuits. Hall effect device is characterized by first and second opposing surfaces, first and second device inputs, and first and second device outputs. A substrate is layered adjacent to one of the first and second opposing surfaces of the Hall effect device and is electrically connected to an output pin of the Hall effect device to eliminate any effects caused by asymmetry of the voltage appearing in the channel relative to the substrate. The net effect of the high linearity interface is to eliminate any adverse effects to linearity of the system, especially at low magnetic flux levels where the output voltage of the Hall device would be relatively small compared to the offset voltage levels involved. The interface virtually eliminates adverse effects from operational amplifier input offset voltages, Hall effect device output offset voltages, and any common mode voltages.

摘要： A solid state motor starter, commonly referred to as a soft starter, is constructed in a manner to be easily manufacturable while at the same time combining all the required components in a relatively small package. A solid state power switch is clamped between a pair of bus bars in an offset manner to accommodate a discrete switching relay mounted in an inverted manner between the line input and the bus bar in communication with the load outputs. When in a motor run mode, current is shunted away from the solid state power switching device and through the switching relay, a substantially linear current path is achieved to reduce power loss and heat buildup. The arrangement allows for a heat sink mounted to one of the bus bars with adequate spacing between the heat sink and the discrete relay for insertion of a cooling fan. Current sensing is achieved with a Hall effect sensor mounted to the bus bar in a small current sensing region that is created by having a pair of slots in the bus bar to direct current. A pair of magnetic pins extend perpendicular from the bus bar to create the magnetic flux for the Hall effect sensor to sense current flow through the current sensing region. The Hall effect sensor circuit board also contains a thermistor which is mounted with adequate insulation yet in thermal communication with the bus bar.

摘要： A magnetic sensor apparatus comprises a magnetic detector (101) that outputs a signal responsive to a magnetic field and a magnetic substance (110) having a cavity (111) in which the magnetic detector (101) is placed. The magnetic detector (101) is placed in the cavity (111) of the magnetic substance (110). The ratio between a magnetic field (H) to be measured and a magnetic field applied to the magnetic detector (101) is set to a specific value, based on at least one of a first demagnetizing factor depending on the shape of the magnetic substance (110) and a second demagnetizing factor depending on the shape of the cavity (111). The magnetic sensor apparatus further comprises a feedback coil (112) that applies a negative feedback magnetic field to the magnetic detector (101) and a reference magnetic field coil (113) that applies a reference alternating magnetic filed to the magnetic detector (101) for controlling the property of the magnetic detector (101).

摘要： A closed loop Hall effect current transformer in which the Hall effect device has an input resistance which varies with its operating temperature. The Hall effect device is driven by a fixed voltage passing through a current limiting a resistor with variations in voltage across the resistor being indicative of the operating temperature of the device. Further, variations in the input resistance of the device caused by variations in its operating temperature is corrected for by mixing a correcting signal with the outputted signal from the device, said correcting signal being derived from a voltage signal taken across the resistor at the driving input of the device.
