A massage device for massaging a body part of a person in an unsupervised and unattended setting. The massage device includes a garment, shaped to provide a snug fit and having a plurality of bladders arranged along the garment to massage the body part. An inflation assembly supplies fluid pressure to each of the bladders to inflate the respective bladders. The bladders may have approximately the same inflated volume thereby equalizing the inflation volume of the respective bladders whereby substantially even inflation timing, with substantially even applied pressure, and, thus, overall smooth massage dynamics may be provided without overly complicated inflation fluid control (e.g., an inflation assembly which supplies a substantially constant inflation capacity to each of the bladders). The garment may include a pocket having an opening communicating with the respective bladders and tubing from the inflation assembly extends into this pocket. The inflation assembly may provide throttled deflation flow, tapered inflation / deflation patterns, and / or a zone selector which allows a user to select a certain zone of the garment.

A tire inflation system includes an air supply source in selective fluid communication with a tire via a pneumatic conduit. A method of inflating the system includes providing a tire pressure retention valve in the pneumatic conduit adjacent to the tire. An inflation pressure of the tire is determined with a step-up procedure, in which air bursts are communicated from the air supply source to a portion of the pneumatic conduit between the air supply source and the tire pressure retention valve. The volume of at least one selected communicated air burst is related to a volume of a section of the conduit. The tire is inflated with an extended-pulse procedure, in which extended bursts of air are communicated from the air supply source to the tire. A shut-down sequence is performed once a predetermined target inflation pressure in the tire is reached.

A two or more chambered airbag provides much improved safety and / or performance. A modified single chamber airbag can be used as the primary chamber of the two-chamber airbag. A piece of fabric of appropriate size is sewn to the inside or outside surface of the front panel of the primary chamber to create the secondary chamber. One or more apertures are opened between the primary and secondary chambers. In order for the secondary chamber to inflate properly, the tethers of the primary chamber are shortened to 50% to 80% of their original length. The size or location of the tether sewing to the inner surface of the front panel of the primary chamber is also adjusted to create a desired shape of the secondary chamber when deployed.

A self-propelled device for locomotion through a lumen, comprising a set of serially arranged inflatable chambers, adjacent chambers being fluidly connected, and a fluid source attached to one end of the set, such that the chambers inflate sequentially. The chambers are constructed of an elastic material and have a wall thickness and dimensions such that they have a characteristic with a non-monotonous relationship between the inflation pressure within the chamber and the chamber's inflated size. The characteristic is such that after an initial inflation pressure peak, the non-monotonous relationship adopts a negative slope, such that the volume of the chamber increases more rapidly than the volume of fluid flowing into it, and the inflation pressure of the chamber falls. This effect causes the chamber to inflate and anchor rapidly, while essentially slowing down the inflation of the succeeding chamber until inflation of the first is complete.
