The present disclosure generally relates to a manifold valve assembly engaged to an inflatable apparatus, such as a cushion to prevent pressure ulcers, for example. The manifold valve assembly is also in communication with a processing device to determine an optimal immersion level for a user seated on the inflatable apparatus. Additionally the processing device, in communication with the manifold valve assembly may save optimal immersion or air pressure levels for comparison to future checks of cushion pressure and send that to a user interface at the processing device. The assembly and processing device may also save and display a history of pressure checks.

A system includes a client application executed by a client computing device for setting up an inflation level and checking an inflation level of an inflatable cushion having at least one air cell or zone and at least one pressure sensor within the cushion that detects air pressure. The client computing device communicates with the inflatable cushion and determines an optimal inflation level for a user of the inflatable cushion.

A bicycle tire pressure cap, used with a bicycle tire valve, comprising a metal case, an anti-leak washer, a ventilation disc, a rubber gasket, a floating holder, a warning plug, a spring and a transparent cover. The bicycle tire pressure has a simple structure, low failure rate, low cost, and can quickly indicate whether the tire pressure is sufficient and effectively enhance the riding safety.

A tire valve unit includes a tire valve and a sensor unit. The tire valve includes a valve stem and a rubber body located on the periphery of the valve stem. The sensor unit includes a sensor mounted on a wheel and a housing that accommodates the sensor and is secured to the tire valve. The tire valve unit is mounted on the wheel by press-fitting the tire valve into a mounting hole in the wheel. The body includes an attaching portion. The tire valve includes an attaching projection that projects in the axial direction of the tire valve from the inside of the attaching portion toward the outside. The tire valve unit further includes a fixture that secures the attaching projection to the housing.

A bicycle air pump includes an air cylinder; a joining member on the cylinder and including upper, intermediate and lower chambers, and a passageway communicating the cylinder with the lower chamber and a relief valve; an activation assembly on the joining member and including a hollow spring-loaded stem in both the intermediate chamber and the lower chamber, an end seal, a cap on the upper chamber, a push rod through the cap to urge against the seal and having an axial hole and a lateral hole communicating with the axial hole, a knob secured to the push rod and the cap, and an outlet; a pressure gauge on the joining member and communicating with the passageway; an inlet assembly secured to bottom of the cylinder and including a check valve; and a blocking member secured to bottom of the stem for blocking the passageway when in an inoperative position.

A wheel module for a tire pressure monitoring system includes an inflation valve of the snap-in type and an electronic casing fixed thereto in a reversible manner. This valve is produced from a resiliently deformable material and includes a valve body and a metal conduit extending therethrough for introducing inflation air. The valve body has a first end provided with a thread for receiving a closure cap and a second end with a hollow metal fixing rod provided with notches fixed thereto. The electronic casing is slidingly mounted on the fixing rod and includes an element for blocking the position of the casing relative to the valve in a reversible manner. The blocking element includes a substantially U-shaped metal wire, a first end and a second end of which are inserted below retention lugs produced on the same face of the casing. This metal wire is insertable into the notches.

A valve stem for mounting and supporting a tire pressure monitoring assembly includes a flange formed after insertion into the wheel rim for preventing movement caused by forces generated during wheel rotation.

Remote safety tire inflation apparatuses may be operable in a tire inflation mode to inflate a pneumatic tire to an initial tire pressure at a safe distance from the tire. The remote safety tire inflation apparatuses may be operable in a tire deflation mode to subsequently deflate the tire to a safe target tire pressure so a user of the apparatus can safely approach the tire to uncouple the apparatus from the tire.

A TPMS-sensor-integrated automatic tire inflation system hose is provided that includes an inspection valve and a TPMS sensor.

A hose kit. The hose kit includes a manifold. The manifold includes an air input, a first air output and a second air output. The hose kit also includes a first air output hose configured to attach to the first air output and a first tee fitting configured to attach to the first air output hose. The hose kit further includes a first tire whip configured to attach to the first tee fitting and a first tire hose configured to attach to the first tee fitting. The hose kit additionally includes a second air output hose configured to attach to the second air output and a second tee fitting configured to attach to the second air output hose. The hose kit moreover includes a second tire whip configured to attach to the second tee fitting and a second tire hose configured to attach to the second tee fitting.
