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 valvetrain includes a rocker arm assembly having an electromagnetic latch housed in a chamber formed by a rocker arm. The chamber may be a retrofit hydraulic chamber. A flux shifting bi-stable latch provides a sufficiently compact design. Isolation of the magnetic elements within the rocker arm chamber may provide protection from metal particles carried by oil in an operating environment for the rocker arm assembly. Wiring connections to the rocker arms may be made through spring posts on the rocker arms. Connection to the rocker arms may be made with springs that can endure the rapid motion induced by the rocker arms. A wiring harness for the rocker arms may attach to hydraulic lash adjusters of the rocker arm assemblies. The rocker arm assemblies and their wiring may be formed into a unitary module that facilitates installation.

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.
Abstract:
An internal combustion engine includes a valvetrain having a rocker arm assembly including a rocker arm on which a latch pin is mounted. An actuator for the latch pin, including an electromagnet, is mounted separately from the rocker arm. Therefore, the rocker arm is able to move independently from the electromagnet. The electromagnet is operative to cause the latch pin to actuate through magnetic flux following a magnetic circuit that passes through the rocker arm. Mounting the electromagnet apart from the rocker arm allows wires powering the electromagnet to be held in relatively static positions. The magnetic circuit is arranged to bring magnetic flux into the latch pin, or a co-acting part, within the volume of the rocker arm. This enables a compact design that is suitable for installation in engines where the available space under the valve cover may be very limited.

A current sensing apparatus is disclosed that provides improved immunity to external magnetic fields, enhanced resolution, and a wide sensing range. The current sensing apparatus includes a conductor having a plurality of current path regions formed therein, which are separated by a pair of slots formed through the conductor. A pair of magnetic field sensors is positioned relative to the pair of slots to sense a magnetic field produced by a current flow through one of the current path regions.
