Filling methods and systems are provided for a conformable fuel tank. In one example, a system comprises an active thermal management arrangement for the conformable fuel tank. The active thermal management arrangement comprises one or more recirculation passage for mixing hot fuel distal to an inlet port of the conformable fuel tank with cool incoming fuel flowing to the inlet port.

An electronic faucet that has a controller module cartridge that is detachably connected to a spout assembly by an adapter.

A method for controlling one or more scent delivery units includes maintaining one or more scheduled events, maintaining one or more scheduled anti-events, and generating, based on the one or more scheduled events and the one or more scheduled anti-events, command data to be communicated to the one or more scent delivery units to control their activation and deactivation. Generating the command data includes identifying a conflicting period of time during which control specified by the one or more scheduled events differs from control specified by the one or more scheduled anti-events and also includes generating command data that gives priority to control specified by the one or more scheduled anti-events. Control for the one or more scent delivery units during the conflicting period of time is in accordance with control logic of the one or more scheduled anti-events and not the one or more scheduled events.

A hydraulic lockout lever failure detection system preferably includes a first analog sensor, a second analog sensor, at least one electronic control module (ECU) and a solenoid valve. The voltage output level of the first and second analog sensors is monitored by the ECU. The solenoid valve controls the flow of hydraulic fluid to operate an excavator or other equipment. The operation of the solenoid valve is controlled by the ECU. However, a second ECU may be used to control the operation of the solenoid valve. A hydraulic lockout lever causes the first and second analog sensors to output either a low voltage to indicate a closed position, or to indicate an open position to the ECU. If the first and second analog sensors output a voltage that is above a low set value or above a high set value, a fault is detected.

A water heater system and method of operating such a system are disclosed herein. In an example embodiment, the water heater system includes a heat exchanger. a heat source inlet by which heated heating fluid can be provided to the heat exchanger, a heat source outlet by which cooled heating fluid can be communicated from the heat exchanger, a water supply inlet by which supply water can be provided to the heat exchanger, and a water supply outlet by which heated water can be communicated from the heat exchanger. Additionally, the system includes a controller, a water supply outlet temperature sensor, a water supply flowmeter, and an actuator. The controller is configured to generate control signals based at least indirectly upon temperature measurements and flow measurements and to provide the control signals to the actuator to regulate a fluid flow of the heated heating fluid into the heat exchanger.

A flow management system includes an expandable device that is configured for attachment to a wall surface of a conduit and that is adjustable between an expanded configuration and a collapsed configuration. The flow management system further includes a fluidic actuator in fluid communication with the expandable device and a control module. The control module is configured to control the fluidic actuator to deliver actuation fluid to the expandable device to expand the expandable device for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to withdraw actuation fluid from the expandable device to collapse the expandable device for opening the channel to a fluid flow within the conduit.

A flow management system includes an expandable device configured for attachment to a wall surface of a conduit and being adjustable between an expanded configuration and a collapsed configuration, an electric actuator in fluid communication with the expandable device, and a control module. The control module is configured to control the electric actuator to flow a current to the expandable device to expand the expandable device for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to terminate a flow of the current to the expandable device to collapse the expandable device for opening the channel to a fluid flow within the conduit.

A flow management system includes an adjustable compactor configured for attachment to a wall surface of a conduit and being adjustable between an extended configuration and a reference configuration, an electric actuator in fluid communication with the adjustable compactor, and a control module. The control module is configured to control the electric actuator to flow a current to the adjustable compactor to generate an electric field that causes extension of the adjustable compactor for compacting a flow blockage within the conduit to create a channel adjacent the flow blockage and to terminate a flow of the current to remove the electric field at the adjustable compactor to cause the adjustable compactor to return to the reference configuration for opening the channel to a fluid flow within the conduit.

A method of managing a fluid flow within a conduit includes determining a presence of a flow blockage within the conduit, the conduit being equipped with an expandable device, controlling a fluidic actuator to deliver an actuation fluid to the expandable device to expand the expandable device radially, compacting the flow blockage radially along a length of the expandable device to create a channel adjacent the flow blockage, controlling the fluidic actuator to withdraw actuation fluid from the expandable device to collapse the expandable device radially, and exposing the channel to open the conduit to fluid flow.
