A buoyancy method for deploying a plurality of floats of a buoyancy system of an aircraft. The plurality of floats comprises a plurality of main floats and a plurality of secondary floats that are folded in flight. The method comprises a step of deploying the main floats in flight prior to ditching, and a step of deploying the secondary floats after ditching.

A method for controlling a compressor system comprising a plurality of compressors, wherein the compressor system is intended to maintain a predefined excess pressure in a pressurized fluid system, wherein decisions are met at fixed or variable intervals as to switching operations for adapting the system to current conditions, wherein—in a pre-selecting step, switching alternatives are excluded from the plurality of combinatorially available switching alternatives, —in a main selecting step, remaining switching alternatives are weighed against one another while referring to one or more optimization criterion (criteria) and optimum switching alternatives are selected from among the given criteria, and—in a control step, the selected switching alternative is output for implementation in the compressor system.

Devices and methods for mass flow verification are provided. A mass flow verifier includes a chamber configured to receive a fluid, a critical flow nozzle upstream of the chamber, a chamber valve, a downstream valve, and a bypass valve. The chamber valve is configured to selectively enable fluid flow from the critical flow nozzle to the chamber. The downstream valve is configured to selectively enable fluid flow from the chamber to a downstream location. The bypass valve is configured to selectively enable fluid flow from the critical flow nozzle to a dump location. The mass flow verifier further includes a controller configured to verify flow rate of the fluid based on a rate of rise in pressure of the fluid as detected by a pressure sensor in the chamber.

A seat post assembly includes a seat post that is electrically adjustable in height. The adjustability may be based on one or more pressures sensed by one or more sensors within the seat post assembly, respectively. The disclosed seat post assembly includes an electronics module. The electronics module may be carried under the seat or saddle and may include a pressure sensor or pressure sensor circuitry.

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

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 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.

In a flow rate controller unit (1) it is thus provided to generate a temporal profile (22) of a volumetric flow, in which temporal profile (22) a switching profile by way of which at least one flow controller (6) is actuated for varying the defined volumetric flow is run.

The regulating second valve regulates the flow rate and/or the determined pressure according to the pressure measured. The regulating second valve is a proportional valve of electrically operated variable throughout PCV type.

Technical solutions are described for predicting linepack delays. An example method includes receiving temporal sensor measurements of a first fluid-delivery pipeline network and generating a causality graph of the first fluid-delivery pipeline network. The method also includes determining a topological network of the stations based on the causality graph, where the topological network identifies a temporal delay between a pair of stations. The method also includes generating a temporal delay prediction model based on the topological network and predicting the linepack delays of a second fluid-delivery pipeline network based on the temporal delay prediction model, where a compressor station of the second fluid-delivery pipeline network compresses fluid based on the predicted linepack delays to maintain a predetermined pressure.
