A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet of weldable material and welding of the second portions to a second sheet of weldable material.

A system for forming a tendon sleeve on an atmospheric balloon is described herein, the system comprising a coupling assembly including a seam coupling mechanism that forms a seam joint between a first gore panel and a second gore panel, the seam joint is spaced from respective first and second lateral edges of the first and second gore panels to form first and second edge flanges, and an edge coupling mechanism that forms an edge joint between the first and second edge flanges and closes a tendon sleeve, the edge joint spaced from the seam joint, the tendon sleeve includes a tendon sleeve passage between the seam joint and the edge joint and between the first and second edge flanges. The system also includes a tendon positioning mechanism that positions a tendon within the tendon sleeve passage. A tendon sleeve formed by this system is also described herein.

The blood pressure measuring device includes a device main body configured to form a flow path of a fluid and supply the fluid, and a cuff to be wound around a living body, the cuff provided with a bag-shaped connection portion with an opening and a connection plate with a hole communicating with the opening; the connection portion formed of a sheet member; the connection plate having a bending elastic modulus higher than that of the connection portion, bonded to the connection portion and adhered to the device main body; and the cuff configured to be inflated when the fluid is supplied to an internal space of the cuff.

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.

A fixture for heat pressing process is applied to a hot pressing machine for hot pressing two elastic plastic pieces so as to manufacture an airbag. The two elastic plastic pieces are disposed between the fixture and the hot pressing machine. The fixture includes a first frame, a second frame and a flexible heat blocking layer. The first frame includes two first brackets, which are separated from each other with a first distance. The second frame includes two second brackets, which are separated from each other with a second distance, and located at two ends of the first brackets, respectively. The flexible heat blocking layer is fixed by the first frame and/or the second frame.

Aspects of the disclosure relate to envelopes for aerial vehicle. The aerial vehicle may include an envelope including a plurality of gores. The aerial vehicle may also include a seal arranged between a pair of the plurality of gores, the seal including six layers of envelope material heat-sealed together.

A therapy wrap for treatment of at least a portion of an animate body having improved kink resistance. The therapy wrap may be selectively reinforced for improved kink resistance in only a portion of the wrap. The reinforcement may decrease the kink radius. The wrap may include a kink reducer in all or only a selected kink-prone region. The kink reducer may be selectively configured attachment points or spot welds. The therapy wrap may include a reinforcement layer of one or more discrete reinforcement members. The wrap may be formed by pre-tensioning the material layers while forming the fluid bladder and/or gas pressure bladder. The therapy wrap may be adapted to compensate for conditions that normally cause kinking of the wrap or buckling of the fluidic channels. Also disclosed are methods of manufacturing the wrap and methods of administering a temperature-controlled treatment to an anatomical body part.
