A method of constructing an inflatable fluidic actuator. The method includes coupling a first interface to a tube configuration of membrane material at a first tube end by coupling the first interface to the tube configuration at the first tube end by generating at least one of: a first bond between the membrane material and one or more first sidewalls of the first interface and a first external face bond between membrane material at the first tube end onto a first external face of the first interface.

A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.

The present disclosure is concerned with a method of forming a seal with a polyethylene based film structure. The polyethylene based film structure has at least one layer formed with an oriented polyethylene having a predetermined melting temperature (T.sub.m). A conductive heat sealing device provides heat to form the seal, where a first sealing bar of the conductive heat sealing device operates at a first operating temperature of at least 10 degrees Celsius (° C.) below the T.sub.m of the oriented polyethylene in the polyethylene based film structure and a second sealing bar of the conductive heat sealing device operates at a second operating temperature of at least 15° C. higher than the operating temperature of the first sealing bar. The seal formed with the polyethylene based film structure retains at least 99 percent of its original surface area prior to forming the seal.

An exoskeleton system comprising an inflatable actuator configured to be worn by a user. The inflatable actuator includes a fluid-impermeable member that defines a fluid chamber at least in part by a membrane material and a first and second interface that each define sidewalls, the membrane material is coupled to the sidewalls of the first and second interfaces.

A flexible container is provided. The flexible container includes four panels. The four panels form (i) a body portion; (ii) a neck portion, and a flare portion that extends from the neck portion; (iii) a tapered transition portion between the body portion and the neck portion; and (iv) the neck portion has a reduced width. The flare portion has an expanded end. The width of the flare portion gradually increases from the neck portion to the expanded end.

A joint apparatus that joins a pouch body to a spout, including: a spout holding unit that holds the spout; a positioning mechanism that positions the pouch body with respect to the spout; and a joint mechanism that joins a pouch mouth of the pouch body to the spout. The positioning mechanism has a pouch-body moving unit that moves the pouch body toward the spout a contact member having a contact part that comes into contact with an end of the pouch mouth, and an absorption mechanism that absorbs a part of a force acting on the pouch body when the end of the pouch mouth comes into contact with the spout or the contact member.

A stop system intended to engage with a tool for heating by direct contact for a machine for plastic welding of a component over an opening in a wall of a motor vehicle tank. The system contains a cam mechanism which includes a straight cam with a longitudinal axis and a follower coupled to the straight cam for converting a translational movement along the longitudinal axis of the follower into a straight or quasi-straight movement of a point of the follower in a direction non-parallel to the longitudinal axis. The cam mechanism of the follower is capable of moving from a rest position, where the stop system is configured to pass freely through an opening in a wall of a motor vehicle tank, to a working position. The stop system is configured to bear against an inner surface of the wall of the tank through which the straight cam passes.

C. higher than the operating temperature of the first sealing bar. The seal formed with the polyethylene based film structure retains at least 99 percent of its original surface area prior to forming the seal.
