A method of treating obstructive sleep apnea includes providing an elongated element having a central buttress area and first and second arms extending from opposite ends of the central buttress area. The method includes implanting the central buttress area in a tongue so that a longitudinal axis of the central buttress area intersects an anterior-posterior axis of the tongue. The first and second arms are advanced through the tongue until the first and second arms engage inframandibular musculature. Tension is applied to the first and second arms for pulling the central buttress area toward the inframandibular musculature for moving a posterior surface of the tongue away from an opposing surface of a pharyngeal wall. The first and second arms are anchored to the inframandibular musculature for maintaining a space between the posterior surface of the tongue and the opposing surface of the pharyngeal wall.

A case includes a case body, a lid, hinges supporting the lid on the case body and a waterproof seal placed on the joining surface of the case body. The lid can be turned for closing on the hinges so as to compress the waterproof seal perpendicularly to the joining surface of the case body. Each hinge is provided with a hinge pin having opposite cylindrical end parts and an offset middle part defining a groove together with the cylindrical end parts. The grooves of the hinges permit first knuckles formed integrally with the lid to sink therein so that the lid held with its joining surface parallel to the joining surface of the case body can be moved toward the case body perpendicularly to the joining surface of the case body to compress the waterproof seal perpendicularly between the joining surfaces of the lid and the case body. The hinge pin is restrained from coming off by the first knuckles when the first knuckles are engaged in the groove.

The invention is a method and system for continuously tracking the movement of cargo in domestic and international shipping from point of departure to point of destination and to prevent hijacking of the same. The system uses one or more wireless electronic seals which can communicate with a central computer system, such as by satellite, providing the current location of the cargo at regular intervals or upon demand. The electronic seals are provided with a unique identification number and are activated upon locking of the seal to the closed cargo container. During shipment, the seal transmits its location to the central computer which compares the location of the shipment to a calculated expected route, notifying the parties to the shipment and government authorities in the event that the cargo is found to deviate from the expected route. The electronic seal is also capable of signaling the central computer when the cargo is opened. If the opening is premature, a second seal hidden within the cargo can be activated to enable tracking of the cargo which may be removed from the container. The system also provides a consolidated, verifiable record of the shipping history of a shipment which can facilitate government clearance and inspections of potentially dangerously handled cargo.

A perforation blade is used for cutting a perforated tear line in a bag to form an easy-open corner portion. The perforation blade includes a base formed to span the corner portion of the bag. The base has a first end adapted to extend to the end edge of the bag proximate a seal line, and a second end adapted to extend to one side edge of the bag. A series of closely spaced perforation teeth are formed with the base, and are adapted to penetrate the first and second walls of the bag to form a corresponding series of perforations at the corner portion of the bag. A starter tooth is formed at the first end of the base, and is adapted to cut a starter nick in a skirt of the bag between the end edge and the proximate seal line. A burst protection gap is formed between the starter tooth and a first of the series of perforation teeth. The burst protection gap is adapted for safely receiving the seal line of the bag to prevent severing the seal line when cutting the perforations.

A down hole tool or plug includes a segmented back up ring acting to minimize extrusion of a seal in an axial direction thereby promoting radial expansion of the seal into engagement with the internal diameter of a casing string. The segments of the ring are joined to a ring body having a passage thereby by a junction having, as its outer dimension, the outside diameter of the tool and an inside dimension provided by a groove opening into the passage.

A wellhead seal assembly forms a metal-to-metal seal between inner and outer wellhead members. A metal seal ring has inner and outer walls separated by a slot. A lock ring has grooves for locking the inner wellhead member to the outer wellhead member during installation. An energizing ring has a C-ring captured on its inner surface. When the energizing ring is moved further into the slot, the C-ring is forced from its pocket and engages the surface of the inner wellhead member, locking the seal assembly to the inner wellhead member.

According to an embodiment of the present invention, a rotating nozzle assembly includes a rotatable shaft having a bore to transport a cryogenic fluid therethrough. The rotatable shaft has an upstream portion associated with a feed chamber and a downstream portion. The nozzle assembly further includes a seal disposed within the feed chamber and surrounding at least a portion of the rotatable shaft, and a seal backup disk disposed proximate the seal. The seal backup disk includes an orifice surrounding an outside diameter of the rotatable shaft, the orifice having a diameter such that, when the cryogenic fluid is flowing through the bore of the rotatable shaft, the rotatable shaft can freely rotate while the seal prevents the cryogenic fluid from seeping past the seal.

The present invention provides a technique for improving the reliability of a semiconductor device where spreading of cracking that occurs at the time of dicing to a seal ring can be restricted even in a semiconductor device with a low-k film used as an interlayer insulating film. Dummy vias are formed in each layer on a dicing region side. The dummy vias are formed at the same intervals in a matrix as viewed in a top view. Even in the case where cracking occurs at the time of dicing, the cracking can be prevented from spreading to a seal ring by the dummy vias. As a result, resistance to moisture absorbed in a circuit formation region can be improved, and deterioration in reliability can be prevented.
