Abstract: Method and apparatus for providing self-contained brake release capabilities in a tractor trailer to facilitate autonomous movement of the trailer within a controlled environment such as in a yard, depot or other facility. Pressurized air is stored in a reservoir of the trailer while the trailer is in a stationary, parked position. Upon receipt of a wirelessly transmitted brake release command, a trailer controller circuit transitions a flow valve to interconnect the reservoir to a brake assembly to apply pressure sufficient to release the brake assembly and enable rolling movement of a wheel assembly of the trailer. In this way, a yard shifter or other transport vehicle can mechanically engage and move the trailer without the need to provide pressurized air or electrical power to the tractor trailer in order to release the brakes. Security protocols can be used to ensure the brake release operation is performed under authorized conditions.

Abstract: Method and apparatus for dynamic inflation control in a vehicle rotary environment. A supply conduit supplies pressurized fluid from a source to a hub assembly having a rotary union and a hub, with the supply conduit passing through the rotary union to the hub. The hub includes a diaphragm disposed between the supply conduit and a lead conduit coupled to an inflatable member. The diaphragm is normally biased against a sealing surface using a biasing mechanism, such as a spring. The biasing mechanism facilitates selective bi-directional fluid flow between the supply conduit and the lead conduit during inflation and deflation of the inflatable member. A supply reservoir and at least one condensation recess may be placed adjacent the diaphragm. The rotary union may be coupled to the hub using a pin and a circumferentially extending slot.

Abstract: A vehicle operational diagnostics and condition response system includes at least an axle supporting a cargo transport unit frame, a suspension disposed between and secured to each the cargo transport unit frame and the axle, a load detection device interacting with the suspension and communicating with a system controller, wherein the system controller is supported by the cargo transport unit frame, and a cargo transport unit health status system supported by the cargo transport unit and configured to communicate with the system controller. The cargo transport unit health status system provides state status information for monitored operational elements of the cargo transport unit.

Abstract: An inflation system can be configured for a rotary environment with a supply conduit passing through a rotary union to a hub. The hub can consist of a diaphragm contacting a force mechanism with the diaphragm separating the supply conduit from a lead conduit. The force mechanism may allow selective bi-directional fluid flow between the supply conduit and the lead conduit in response to fluid pressure that differs from a predetermined threshold pressure.

Abstract: A tire pressure management system includes at least an axle, which houses pressurized fluid, and is supported by a tire. A vehicle frame supported by the axle, by way of a suspension is disposed between frame and the axle. Also included is a pressure management controller (PMC) supported by the frame, which communicates with the tire. A load detection device (LDD) interacting with the suspension determines a value for a load supported by the suspension. The PMC provides at least a central processing unit (CPU) programmed with a lookup table that associates the value determined by the LDD with a predetermined pressure for the tire. The CPU directs an inflation, else a deflation of of the tire based on the determined value.

Abstract: A metal insert, in particular a threaded metal insert, adapted to be embedded in a receiving bore of a plastic part. The insert has a sleeve-like body member. At least one row of teeth projects from the peripheral surface of the body member, which teeth are circumferentially spaced with respect to each other. Each tooth is of a shape such that it diverges from a tooth front end in an axial direction and terminates in an end face extending transverse to said axial direction at a tooth terminal end. Between the teeth are gaps which taper in said axial direction while they remain open between said end faces of adjacent teeth. The teeth ensure that insertion forces for urging the insert into the plastic part are minimal, while resistance to withdrawal of the insert is maximal.
