  • Patent number: 10301792
    Abstract: A dampener includes an external reservoir which stores hydraulic fluid due to fluid expansion caused by heat generated by fluid flow through valves that cause a drop in fluid pressure. The primary manifold controls hydraulic fluid flow within the dampener. A diverter valve communicates with the passageways between the dampener and the external reservoir. Hydraulic flow is bi-directional between the primary manifold and the accumulator. Hydraulic fluid flow is restricted when flowing from the primary manifold to the accumulator but is unrestricted when flowing from the accumulator back to the primary manifold and dampener.

  • Patent number: 10295007
    Abstract: A load absorber dampens relative movement between subsea bodies. The load absorber is cooperable with an actuating member such as a male piston element or a female cup on an opposed subsea body. The load absorber comprises a hollow structure defining an internal flow path for water. A flow restrictor acting on the flow path restricts a distal flow of water along the flow path from a proximal opening, caused by convergence between the actuating member and the load absorber. The flow restrictor comprises a shuttle element to restrict the flow path that is mounted to the structure for automatic movement from a first state to a second state in response to an increase in water pressure at the proximal opening. In the first state, the shuttle element effects greater restriction of the flow path than in the second state.

  • Patent number: 10286890
    Abstract: A wake-up device for a brake system component of a vehicle includes a magnet that is arranged to be set, via a transmission device, in rotational motion jointly with a shifting of a driver brake force transmission component, thereby effecting a relative motion between the magnet and an electrical conductor. The relative motion induces an induction voltage. An output device outputs the induction voltage or a wake-up signal generated based on the induction voltage to the brake system component, thereby controlling the brake system component to transition from a first energy use mode to a second energy use mode. A method includes controlling the brake system component to transition from the first energy use mode to the second energy use mode by outputting the induction voltage or wake-up signal generated as described above.

  • Patent number: 10232832
    Abstract: An emergency breakaway system having an integral electrical testing system for confirming the functionality of a trailer's electric brake solenoids and electric lights includes housing enclosure having interface screen, a testing battery, and a testing controller. The trailer electrical system testing device is operative to replace a conventional emergency breakaway system, supplying the emergency breakaway functionality while also enabling real time, on demand testing of the trailer's electric brakes and lights. An integrated activation routine causes electricity to be supplied directly to the electric brakes in periodic, on/off intervals, thereby operating the electric brakes intermittently, for a predetermined time period. The activation routine thus allows a user to walk around the trailer and listen for activation of the electric brake solenoids as well as check and verify the functionality of the brake components.
