Abstract: A movable barrier operator comprising a motor, communication circuitry configured to receive a control signal and communicate with a door lock associated with a passageway door, and a controller. The controller is configured to authenticate the control signal, wherein authenticating the control signal includes associating the signal with a first level of access or a second level of access. The controller is further configured to communicate with the door lock via the communication circuitry to permit opening of the passageway door in response to associating the control signal with the first level of access and inhibit opening of the passageway door in response to associating the control signal with the second level of access. The controller is configured to cause the motor to open the movable barrier regardless of association of the control signal with the first level of access or the second level of access.

Abstract: A system and method recover process gas from a source volume at a source pressure to a destination volume at an equal or greater pressure. A regulation process receive the process gas from the source volume and steps down the pressure. Each regulation uses one or more stage each using a pressure control valve for pressure step down and a heat exchanger for reheating the process gas thereafter. A gas scrubber receives the process gas from the regulation stages and collecting liquid from the process gas. A compression process receives the process gas from the gas scrubber and steps up the intermediate pressure to a final pressure. The compression can use one or more compression stages, each having a compression cycle for pressure step up and a heat exchanger for cooling the process gas thereafter. A discharge vessel receives the process gas from the compression process and discharges the process gas at the final pressure to the destination volume.

Abstract: A fuel vapor recirculation system includes a filler neck adapted to receive a refueling nozzle that dispenses fuel into the filler neck. A fuel tank receives fuel from the filler neck through an inlet check valve. The check valve is disposed in the fuel inlet opening and is normally closed. The check valve opens when fuel is dispensed into the fuel tank. The check valve defines a vent hole that is always open. The fuel tank also includes a fuel limiting vent valve and a grade limit vent valve. A fuel vapor cannister collects fuel vapor and selectively supplies fuel vapor to an intake manifold of a vehicle. The fuel vapor recirculation manifold receives fuel vapor only from the fuel limiting vent valve and the grade limit vent valve in the fuel tank and does not receive fuel vapor directly from the filler neck.
