An automatic inflator device includes a housing that houses various operational components of the automatic inflator device such as a power source that is electrically coupled to a pump. A coupling portion attached to the housing selectively secures the automatic inflator device to an inflatable object, such as an inflatable watercraft, where the automatic inflator device may remain secured even while the inflatable object remains fully operational, such as while the inflatable object is in use. The pump may be selectively energized to pump air into the inflatable object via a fluid conduit. For example, the pump may be energized or de-energized based on user input or automatically based on a measured pressure of the inflatable object. Optionally, the automatic inflator device may be incorporated into an inlet valve of the inflatable object as the inflatable object is originally manufactured.

An apparatus for a shoe sole with an air pump for adjusting pressure levels in air chambers distributed throughout the sole, and a battery. A sole system cloud based application remotely connects to and adjusts the air chambers according to user preferences.

A pressure cell for sum frequency generation spectroscopy includes: a metal pressure chamber; a heating stage that heats a liquid sample; an ultrasonic stage that emulsifies the liquid sample; a chamber pump that pressurizes an interior of the metal pressure chamber; and a controller that controls the chamber pump, the ultrasonic stage, and the heating stage to control a pressure of the interior of the metal pressure chamber, an emulsification of the liquid sample, and a temperature of the liquid sample, respectively. The metal pressure chamber includes: a liquid sample holder that retains the liquid sample; a removable lid that seals against a base; a window in the removable lid; a sample inlet that flows the liquid sample from an exterior of the metal pressure chamber to the liquid sample holder at a predetermined flow rate; and a sample outlet.

A pump communicates with a waste fluid storage container and generates a negative pressure to draw waste fluids into the waste fluid storage container. A sensor measures a negative pressure. A driving unit performs driving control upon the pump. A computation unit detects, for example, the amount of air leak from the change in negative pressure. The driving unit performs driving control using an ON period Ton in which the pump operates and an OFF period Toff in which the pump stops. The computation unit detects the amount of air leak using the change in negative pressure in the OFF period Toff.

A vehicle system for a vehicle includes a controller. The controller is configured to transmit a first control signal to a transmission device of the vehicle to engage a first mode of the transmission device, acquire information regarding a pressure of an inlet flow of water received by a pumping system of the vehicle, and transmit a second control signal to the transmission device to engage a second mode of the transmission device based on the information.

Provided is a pressure balancing device, having a mounting seat and a cover, wherein an accommodating cavity is formed between the mounting seat and the cover. The pressure balancing device may also have a partition member, wherein the partition member divides the accommodating cavity into first and second accommodating cavities. The partition member may also include a support portion and an elastic portion, the support portion being disposed on the elastic portion and having a vent hole capable of fluidly communicating the accommodating cavities. The elastic portion is elastically deformable so as to move the support portion relative to the cover. The pressure balancing device may also have a breathable film that is disposed on the support portion and covers the vent hole, and that is movable as the support portion moves.

A system (15) regulates a temperature of fluid in a sector of a fluid distribution network, including a feed line (11) transporting fluid from a thermal energy source (3) to a thermal energy consumer (7) within the sector and a return line (13) transporting fluid back. A bypass line (17) connects the return line to the feed line, mixing fluid from the return line into the feed line. A pump is at the bypass line. A temperature sensor determines a temperature of fluid in the feed line downstream of the bypass line. A pressure sensor determines an uncontrolled pressure difference between the feed line and the return line, or an uncontrolled pressure difference correlated therewith. A control unit controls the speed of the pump with a closed-loop control for achieving a target feed line temperature based on the determined temperature, and a feed-forward control compensating fluctuations of the pressure difference.

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network.
