    Abstract: A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle or a coupling between a vehicle body and a suspension of the vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow and vehicle weight sensing coupling devices installed on different types of automobile cars and trucks.

    Abstract: A washing device for a vehicle accessory that includes a washer housing with a ring portion and a fluid source attachment. The ring portion has a main opening for receiving a portion of the vehicle accessory, an attachment side configured for mounting the washer housing, a washing side configured to frame the vehicle accessory, and a transition portion between the ring portion and the fluid source attachment. A nozzle end of the fluid source attachment has at least one fluid channel defined by a nozzle protrusion on the nozzle end. The fluid channel is configured to discharge the fluid to the washing side for cleaning the vehicle accessory by creating a plurality of fluid flow pathways of the fluid between the nozzle end and the transition portion, wherein the plurality fluid flow pathways interact with one another to form at least one vortex in the flow of the fluid.

    Abstract: A system and method for controlling locomotives. The system includes a remote control unit (RCU) comprising a processing device and a computer-readable storage medium and a locomotive control unit (LCU) comprising a processing device and a computer-readable storage medium. The LCU is coupled to a locomotive control system of a locomotive for controlling the locomotive and acquiring data therefrom. The LCU is configured for listening to a common radio-frequency channel for a transmission by a network node, waiting for the channel to become free, and transmitting a message after the channel has become free. The RCU is configured for listening to a common radio-frequency channel for a transmission by a network node, waiting for the channel to become free, and transmitting a message after the channel has become free. The system may include one or more repeaters for extending an operational area of the system.

    Abstract: A magnetoelastic sensor. The magnetoelastic sensor uses strain-induced magnetic anisotropy to measure the tension or compression present in a plate. During construction, an annular region of the plate is magnetized with a circumferential magnetization. Magnetic field sensors are placed near this magnetized band at locations where the magnetization direction is non-parallel and non-perpendicular to the axis of tension. The strain-induced magnetic anisotropy caused by tension or compression then produces a shift in the magnetization direction in the plate regions near the field sensors, thereby causing magnetic field changes which are detected by the magnetic field sensors. The magnetic field sensors are connected to an electronic circuit which outputs a voltage signal which indicates the tension or compression in the plate.

    Abstract: A rack cabling system including a rack having mounted thereon a first hardware component and a patch panel housing mounted on the rack adjacent the first hardware component. The patch panel housing populates no more than a three rack unit (RU space), the patch panel housing including a first end having cable pathway openings and a second end having connector elements mounted therein. The patch panel may have a first cable pathway opening located adjacent the first side of the housing and defining a primary position and a first connector element mounted on the second end and the first connector element having a first position corresponding to the primary position of the first cable pathway opening. Cable harnesses axe routed with less than three bends of the cables between the first hardware component and the patch panel housing, so the first cable harness is terminated at the first connector element in the first position.
