A pump head configured to secure various air valve types is disclosed. The pump head may include a housing defining an aperture sized and shaped to receive a valve head therein; a moveable pin disposed within the housing defining a pin notch disposed about an exterior circumference of the moveable pin; a first taper unit disposed in the housing; a second taper unit disposed in the housing and adjacent to the first taper unit, the second taper unit biased away the first taper unit; and an elastic ring disposed between the first and second taper units, wherein the second taper unit is moveable towards the first taper unit, thereby compressing the elastic ring circumferentially in at least one of two positions, the elastic ring compressed about the pin notch in the first position and about the valve head in the second position.

A tire-to-tire pressure equalizing system includes: (a) a flexible conduit providing an airflow passageway therethrough; (b) a first coupler configured to connect to a first free end of the flexible conduit and engage with an air valve of a low-pressure tire; and (c) a second coupler having a check valve configured to connect to second free end of the flexible conduit and engage with an air valve of a high-pressure tire. The check valve is configured to allow air to transfer from the high-pressure tire to the low-pressure tire until an equilibrium is reached. A tee joint includes a connection for a first coupler and one or more conduits to allow for three or more tires to connect until an equilibrium is reached.

A hose assembly utilizing an internal lumen connecting multiple end ports, with one end port of the assembly configured to be connected to the air stem of a deflated tire and the other end port (or ports if there are more than two) are configured to be connected to the air stem of one or more additional tires of higher pressure, such that upon the opening of the end ports, air is transferred through the internal lumen from the higher pressure tire(s) until a sufficient amount of air has been input into the deflated tire to allow usage of the vehicle. Various configurations including a single, straight hose configuration or various branched configurations may be used to transfer air between tires in different situations.

Methods and systems are provided for using a forced induction system of an engine on-board a vehicle as a source of compressed air to pressurize depressurized objects on-board and external to the vehicle. In one example, a method may include, in response to a pressure of the depressurized object being below a threshold pressure while the engine is off, fluidly coupling a discharge of a forced induction system to the depressurized object, wherein the engine includes the forced induction system, and pressurizing the depressurized object by supplying electrical power to the forced induction system.

A pressurized fluid supply apparatus and method of supplying pressurized fluid is provided. The pressurized fluid supply apparatus includes a housing configured to rotate about an axis, at least one fluid pump coupled to the housing and configured to pressurize a fluid therein, and at least one movable element disposed within the housing. The at least one movable element is configured to move within the housing when the housing rotates about the axis, which causes the at least one movable element to be in periodic driving engagement with the at least one fluid pump to cause the fluid to be pressurized.

A service robot can detect one or more makers positioned on relative surfaces of a vehicle. Each marker can include data corresponding to its location on the vehicle. The service robot can determine the location of the markers based on the data. The service robot can also determine the location of a service area proximate to the markers. The service robot can receive data generated by the vehicle corresponding to at least one maintenance condition for the vehicle related to the service area. The service robot can select a service to perform on the vehicle based on the at least one maintenance condition. The service robot can be controlled so as to perform the selected service on the vehicle.
