The present invention provides a life jacket. In an embodiment, the life jacket includes a jacket member; and an air blowing member which is provided in the jacket member to inject air to the jacket member, wherein the air blowing member includes a base part coupled with the jacket member; and a tube part extending from the base part, wherein a flexible portion is formed in a part or the entire of the tube part.

The present disclosure provides a balloon dilation catheter that includes a handle (102), a substantially rigid inner guide member (108) coupled to the handle, a shaft (118) arranged over the inner guide member, a balloon (120) coupled to the inner guide member, and a polymer ball tip (122) positioned at a distal end of the balloon. To treat a sinus drainage pathway of a subject using the balloon dilation catheter, the substantially rigid inner guide member is positioned into the drainage pathway of the sinus of the subject via a nasal passageway. The balloon is then inflated to expand or otherwise remodel the drainage pathway.

The invention relates to the use of a low Tg compatible resin as an adhesive layer for the welding of a thermoplastic composite structure to a thermoplastic or thermoset structure. The invention is especially good for the welding of large parts, such as wind turbine halves and spar caps. A useful thermoplastic composite is one formed by the infusion and curing of long fibers by a reactive acrylic liquid resin system, such as ELIUM® resin systems from Arkema.

A protective guard for a hand, finger or thumb includes a first thermoplastic layer heat welded to second thermoplastic layer. The second thermoplastic layer has a thickness that is greater than the thickness of the first thermoplastic layer.

According to one aspect of the present invention, provided is a method of attaching an emblem to a vehicle seat, the method including providing a seat and an emblem, the seat having an outer surface on which a coating layer is formed, removing the coating layer to correspond to an edge of the emblem, aligning the emblem with the seat to correspond to a portion in which the coating layer is removed, and attaching the emblem to the seat by pressing the emblem using a mold unit and applying a high-frequency current.

An apparatus for forming a weld between a first portion of a biocompatible conductive thermoplastic material and a second portion of a biocompatible conductive thermoplastic material comprises a first electrode, a second electrode, and a structure for holding said first and second electrodes in opposition to one other with a space therebetween for receiving said first portion and said second portion in contact with one another. The structure is electrically non-conductive and an electrical circuit comprising a power source and a switch arranged such that closure of said switch applies a voltage potential across said first electrode and said second electrode so as to generate heat via electrical resistance, the heat being sufficient to melt regions of said first and second portions.

A cushioning article comprises a first and a second polymeric sheet bonded to one another and enclosing an interior cavity. The polymeric sheets retain a gas in the interior cavity. A tensile component disposed in the interior cavity includes a first tensile layer, a second tensile layer, and a plurality of tethers spanning the interior cavity and connecting the first tensile layer to the second tensile layer. An inwardly-protruding bond joins the first polymeric sheet to the first tensile layer, protrudes inward from the first polymeric sheet toward the second polymeric sheet, and partially traverses the plurality of tethers. The first polymeric sheet is displaced from the first tensile layer adjacent to the inwardly-protruding bond by the gas. A method of manufacturing a cushioning article is disclosed.
