    Abstract: A position detection device configured for use with a locking differential is configured to determine a position of an armature in relation to a stator. The stator has a primary coil. The armature moves relative to the stator between engaged and disengaged positions corresponding to the locking differential being in a locked and unlocked state. The position detection device includes a secondary coil disposed proximate to the primary coil. The secondary coil is configured to determine a change in inductance based on movement of the armature. The change in inductance is indicative of a change in position of the armature relative to the stator.

  • Patent number: 10987557
    Abstract: A flexible elastomeric grip for the shaft of a golf club having an end cap with a cavity for receiving a sensor and/or counterweight. The cap has a durometer hardness equal to or greater than the tubular body portion of the grip and a flange sized to match the larger diameter of the body, with a sleeve engaging the inner periphery of the larger end of the tubular body. In one version of the cap, the sleeve portion is extended in length and has stiffening ribs on the outer surface of the sleeve; and, in another version, the sleeve is shorter and may also have stiffening ribs on the outer surface of the sleeve. In another version of the cap, fibrous material is disposed in the flange and sleeve to increase lateral stiffness without increasing durometer.

  • Patent number: 10992126
    Abstract: A method involves a circuit interrupter installation having a circuit interrupter with a plurality of poles and an ETU electrically connected with a neutral current sensor situated in proximity to a neutral conductor. The method includes determining that a plurality of fundamental frequency phase current vectors, when summed, are substantially equal to a fundamental frequency neutral current vector, and/or that a plurality of triplen odd-numbered harmonic phase current vectors, when summed, are substantially equal to a triplen odd-numbered harmonic neutral current vector. Responsive to the determining, the method includes outputting a notification which represents a possibility that a neutral current detection apparatus is mis-wired, and/or employing with the ETU a reverse vector that is an opposite of the fundamental frequency neutral current vector in the ongoing monitoring for an event that would trigger the movement of the circuit interrupter from the ON condition to the OFF or TRIPPED condition.
