The pushing apparatus has a pushing portion adapted to drive the valve seat. The pushing apparatus engaging the valve engaging head includes the pushing portion pushing the first abutting portion, thereby driving the valve seat toward the second connection hole.

A device includes a balloon inflation module having an involuted balloon housed within a lumen, an integrated reservoir in fluid communication with the involuted balloon where the balloon inflation module is configured to selectively displace a volume of fluid from the integrated reservoir into the involuted balloon and from the involuted balloon into the integrated reservoir. The device also includes a port configured to receive an accessory module. In one embodiment, the accessory module is a communication module having a logic circuit coupled to an ambient microphone configured to pick up ambient audio content, an ear canal microphone configured to pick up audio in the proximity of an ear canal, and an ear canal receiver configured to provide audio content in the proximity of the ear canal. In some embodiments, the integrated reservoir is formed within portions of a push button spring-loaded pump assembly. Other embodiments are disclosed.

An assembly for a tire pressure management system includes a housing. The housing includes a first branch and a second branch. The second branch is oriented at an oblique angle with respect to the first branch. The first branch and the second branch are in fluid communication with each other and a main branch. The main branch is rotatable with respect to the first branch. A valve assembly is housed within the first branch. The valve assembly provides selective fluid communication between a portion of the tire pressure management system and the main branch. A pressure relief valve assembly is housed within the second branch. The pressure relief valve assembly provides selective fluid communication between the assembly and the atmosphere.

At least one exemplary embodiment is directed to earpiece devices that share information with other earpiece devices within range (e.g., GPS location and identity). For example multiple users can send signals to each individual earpiece when in range or to a mobile audio communications device via a wireless connection with each earpiece.

A fluid controller comprising a housing separating an interior of the housing from an inflatable bladder is disclosed, the fluid controller including a plurality of valves fluidly coupling the interior of the housing to the inflatable bladder through a respective opening in the housing, a pump located at least partly within an interior of the housing, wherein the plurality of valves and respective orifices are configured to provide a fluid path between the interior of the housing and the inflatable bladder during inflation of the inflatable bladder, and wherein a valve and respective orifice is biased open to provide a fluid path between the interior of the housing and the inflatable bladder for fluid release.

High-altitude balloons and apparatuses for filling such high-altitude balloons are provided. As an example, an apparatus for filling a high-altitude balloon includes a tube extending through envelope material of the balloon is provided. The apparatus also includes a flange connected to a first end of the tube. The flange is connected to an interior surface of the balloon. A fitting is connected to a second end of the tube. The fitting is configured for attachment with an apparatus for filling the balloon with lift gas. In addition, methods of filling high-altitude balloons with lift gas and methods of manufacturing balloons are also provided.

A valve assembly for controlling fluid communication between fluid chambers in a device such as an inflatable device includes a valve body having first and second ports for fluidly connecting to first and second fluid chambers, and defining a plurality of primary valve seats in series between the ports. A plurality of compound valves are within the valve body and each includes a primary valve member movable to close or open one of the primary valve seats, and a secondary valve member movable to close or open a secondary valve seat in the primary valve member.

A device provides a pneumatic pressure medium via a pressure medium source for at least one pressure medium chamber in particular of a vehicle seat of a motor vehicle. The device has a pressure medium source for the pressure medium and a pressure medium line disposed between the pressure medium source and at least one valve. At least one connection for a pressure medium line is disposed between the valve and the pressure medium chamber. A control module actuates the pressure medium source and the at least one valve. The device further has a housing. A motor of the pressure medium source is located between the control module and a pump of the pressure medium source.

A valve for an inflatable device is disclosed. The valve includes a base configured to seal to a fluid impermeable wall of a bladder of the inflatable device, a cap including a rim, and a seal. The bases defines an orifice for exhausting fluid from an interior of the inflatable device and a sealing surface. The rim can include a generally circular peripheral region including at least one rib located about an underside of the peripheral region and a cavity defined in part by at least one wall located radially inward of the rib. The seal can include a first end region secured to the cap within the cavity between the at least one wall and the at least one rib and a second end region configured to move with the at least one first end region secured to the cap.

An inflator valve connector includes a housing, a connection assembly, a valve seat, and a pushing member. The connection assembly is rotatably arranged in the housing and includes a first connection hole adapted to connect a Presta valve and a second connection hole adapted to connect a Schrader valve. The valve seat has a first abutting portion faced to the first connection hole and adapted to abut a lock nut of the Presta valve, and a second abutting portion faced to the second connection hole and adapted to abut a valve core of the Schrader valve. The pushing member removably contacts the connection assembly and has a pushing portion adapted to enter the housing via the first connection hole and to push against the first abutting portion, causing the valve seat to move relative to the housing and to close to the second connection hole.
