System and method for welding a chamber
A method of forming a fluid-filled chamber for an article of footwear is provided and includes positioning a first sheet of material and a second sheet of material in a pressure chamber, increasing a fluid pressure within the pressure chamber to a first value, and coupling the first sheet of material to the second sheet of material within the pressure chamber to define a fluid-filled chamber defined by the first sheet of material and the second sheet of material and having a fluid pressure equal to the first value. The method also includes decreasing the fluid pressure within the pressure chamber to a second value.

Rearview assembly housing with radio frequency activated bond
A method of making a rearview assembly includes operably coupling a rearview device with a front housing. A bonding material is applied to the front housing and a printed circuit board is operably coupled with the front housing. A rear housing is engaged with the front housing. Energy is applied to bond the front housing with the rear housing.
Bleach compatible polyolefin mattress cover
A bleach compatible mattress cover made of a non-woven polyolefin material and defining an interior cavity. The interior cavity configured to receive a mattress structure which may include a first and second support structure disposed in the interior cavity. In certain embodiments, the mattress cover has a Moisture Vapor Transfer Rate of greater than or equal 400 to less than 10,000, 7500 or more particularly less than 5000 grams per square meter per day and a hydrostatic head of 100 cm or greater and passes ASTM 1670 and ASTM 1671.

HIGH FREQUENCY ADHESIVE BONDING
A system and method for bonding a first layer of material to a second layer of material includes a first electrically conductive plate, a second electrically conductive plate spaced apart from the first electrically conductive plate. The second electrically conductive plate is electrically grounded. A high frequency generator in electrical communication with the first electrically conductive plate supplies high frequency electrical signals to the first electrically conductive plate. An adhesive applied to one of the first and second layers of material has an electromagnetic susceptor material that when subjected to the electric field heats the adhesive to an adhesive curing temperature to bond the first layer of material to the second layer of material. A clamping mechanism applies pressure to one of the first and second layers of material to maintain contact between the first and second layers until an adhesive cure time has lapsed.
MOLDED BODY, JOINING METHOD, AND METHOD FOR PRODUCING MOLDED BODY
A molded body includes: a first portion including a first material that contains a first thermoplastic resin and a dielectric filler that generates heat upon application of a high-frequency electric field; and a second portion including a second material different from the first material of the first portion.

MATTRESS RETENTION ASSEMBLY AND RADIOFREQUENCY WELD IN SURFACE COVERS
A mattress assembly includes a mattress and an outer mattress shell that covers the mattress and has a patient support portion and a sleep deck portion. The outer mattress shell defines an interior surface and an exterior surface. A bonding strip is coupled to the interior surface of the outer mattress shell and a fastening strip is coupled to the exterior surface of the outer mattress shell. A weld extends through the exterior surface and through the interior surface of the outer mattress shell. A clasp locker is operably coupled to the fastening strip and detachably couples the patient support portion to the sleep deck portion of the outer mattress shell.
CUSHIONING ARTICLE WITH TENSILE COMPONENT AND METHOD OF MANUFACTURING A CUSHIONING ARTICLE
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.
