A portable inflation device having a pump, a control device, a user interface, and an inflation indicator. The pump includes an elongated hose with an inflation nozzle. The control device controls operation of the pump and is configured to sense a current pressure of an object, calculate the estimated remaining time to inflate the object to a target pressure, and display the remaining time using the inflation indicator. The user interface is configured to allow a user to enter the target pressure into the control device.

A vehicle operational diagnostics and condition response system includes at least an axle supporting a vehicle frame, a suspension disposed between and secured to each the vehicle frame and the axle, a load detection device interacting with the suspension and communicating with a system controller, wherein the system controller is supported by the vehicle frame, and a vehicle pairing circuit, the vehicle pairing circuit interacting with the system controller. The vehicle pairing circuit activated by the system controller in response to load detection data received by the system controller from the load detection device.

An apparatus for setting inflation pressure used to support a vehicle comprising a tire includes an air dispensary, a transponder, and a data-processing system. The transponder is coupled to the air dispensary and to the data-processing system. It receives, from the vehicle, a wireless transmission having first information. The data-processing system executes a host process that receives the first information, and that obtains, based at least in part on the first information, second information. The first information comprises information from which an appropriate inflation pressure for the first tire is obtainable. The second information comprises information indicative of an appropriate inflation pressure for the first tire.

Various multifunctional dispensing systems with overhead fuel/air delivery and methods for using the same are provided. Such a system can include a dispenser system and an overhead delivery unit suspended on tracks above a vehicle drive aisle at a fueling station. The overhead delivery unit can include a fuel dispensing nozzle and an air dispensing nozzle that can be moved about the tracks so as to optimally position the nozzles to be approximately overhead the fuel doors and tires, respectively. Such an arrangement allows a customer to refuel their vehicle and inflate their tire(s) without moving their car between each transaction.

A rotary air pipe connecting an air outlet of an inflator includes a pipe body, a sleeve with an inner wall and an outer wall, and a first sealing ring. The pipe body has main body and a bottom portion, a top of the main body is provided with a joint, a bottom portion has a front portion and a back portion. The bottom portion passes through the sleeve, the front portion fits the inner wall of the sleeve, the back portion extends out of the sleeve. The bottom portion can rotate around an axial direction of the pipe body in the sleeve; the bottom surface of the sleeve is provided with a thread connecting with the front wall. The back portion is movably inserted into the air outlet, the first sealing ring is sleeved with the back portion, the first sealing ring fits the back wall.

An air pressure maintenance apparatus and method uses one or more high-pressure gas storage tanks coupled to an inflation hose via a calibrated rigid measurement chamber and automated system of valves to permit rapid inflation of a tire or other inflatable device to an accurate target pressure accounting for temperature effects, and recording accurate pre- and post-inflation pressure for analysis of deflation over time.

A system and method provide automatic vehicle tire air pressure monitoring, warning, and maintenance for a vehicle. The vehicle includes a controller, wheel rims having tires coupled to wheel hubs, an air compressor configured to inflate the tires, a pressure sensor contained within each wheel rim on a vehicle for measuring air pressure within a tire located on each wheel rim, the compressor coupled to the tire rims for providing needed pressurized air, the compressor, an air pressure line connecting the compressor to the wheel rims, a driver display providing a warning to a driver, and a controller. The controller reads an air pressure value of the air pressure within each tire, determines whether the air pressure values within each tire, when one or more of the air pressure values are below the pre-determined value, activates the compressor to add air to each of the four tires needing the air pressure, and provides the driver a visual status of the air pressure values within in each of the tires and a visual status of the compressor state.

A compressor unit (38) for supplying pressurized medium to a tire mounted on a vehicle wheel rim (34), having a compressor (58) for exerting pressure on a fluid medium that is to be conveyed into the tire. The compressor unit (38) is dimensioned to be accommodated in a center bore (44) of the vehicle wheel rim (34) when the vehicle wheel rim (34) is in the mounted state on a wheel hub (62); and the compressor (58) can be driven by a drive unit (56) positioned in the vicinity of the center bore (44) of the vehicle wheel rim (34). The compressor unit (38) is usable with a vehicle wheel rim (34) having a pressurized medium supply device (22) for a tire that is mounted on the vehicle wheel rim (34), as well as a vehicle having a vehicle wheel that includes such a vehicle wheel rim (34).
