    Abstract: A current sensing assembly includes a conductor having a first side, a second side opposite the first side, a third side, and a fourth side opposite the third side. The first side has a first notch formed therein and the second side has a second notch formed therein opposite the first notch. The current sensing assembly also includes a sensor assembly including a first magnetic sensor disposed in the first notch or proximate to the third side of the conductor between the first and second notches, and a second magnetic sensor disposed in the second notch or proximate to the fourth side of the conductor between the first and second notches.

    Abstract: A force sensor can include a magnetic field generator, a magnetic flux return, and a magneto-elastic layer. The magnetic flux return can extend along a first portion of at least one pathway of magnetic flux generated by the magnetic field generator. The magneto-elastic layer can be operable to be in contact with a surface subjected to force and thereby strained. The magneto-elastic layer can extend along a second portion of the at least one pathway of magnetic flux distinct from the first portion.

    Abstract: A latching electromechanical actuator (9) includes a soft iron armature (31) movable between first and second positions, a permanent magnet (5A), a solenoid (23), and a soft iron external frame (11). The permanent magnet (5A) may be stationary relative to the solenoid (23) and operative to hold the armature (31) stably in either the first position or the second position. The actuator (9) provides two distinct magnetic flux paths (24A, 24B), one or the other of which is the primary flux path for the permanent magnet (5A) depending on whether the position of armature (31). Both flux paths pass through the armature (31). One of the flux paths may pass through the external frame (11). The other does not. The actuator (9) may include two permanent magnets (5) performing complementary roles for the first and second positions. The actuator (9) can be simply constructed, compact, and highly efficient.

    Abstract: Multi-layer capacitor divider voltage sensors include a plurality of voltage sensor conductive layers having sensor to ground interface surfaces. Respective voltage sensor conductive layers are connected to each other and sensor output voltage Vs by continuations of material forming the interface surfaces extending therebetween. The voltage sensors also include a plurality of conductive ground layers connected to electrical ground, the ground layers interleaved with the voltage sensor conductive layers so that a conductive ground layer resides between adjacent conductive voltage sensor layers. A first voltage sensor conductive layer (closest to a line conductor) is electrically connected to the other conductive voltage sensor layers and output voltage Vs and has a sensor to conductor interface surface with a corresponding interface area. The interface areas and the gap distances are configured to provide desired capacitance for attenuation of conductor voltage Vc for a suitably sized Vs in a compact sensor package.
