Methods and devices are disclosed for manipulating the tongue. An implant is positioned within at least a portion of the tongue and may be secured to other surrounding structures such as the mandible and / or hyoid bone. In general, the implant is manipulated to displace at least a portion of the posterior tongue in an anterior or lateral direction, or to alter the tissue tension or compliance of the tongue. Methods and devices for tensioning a glossopexy system are also disclosed. A tether can include a tether protection element configured to prevent overextension of the tether.

It is the object of the invention to provide a knee bracing system that bolsters the body's natural ligaments to reduce the knees proneness to injury or re-injury. The invention is a cable system that acts much like the body's natural ACL and MCL. The cables are routed around the knee joint in a way that resists the forces that cause excessive joint movement and injury to the ACL and or MCL. As the leg travels through the range of motion the cables provide external hyper extension, bending, and rotation support preventing the tibia bone from moving forward (hyper extending) or twisting (lateral rotation) and or laterally bending with respect to the femur.

The invention relates to a backpack with a extendable left leg exoskeleton and a extendable right leg exoskeleton which can be extended from the backpack and attached to the appropriate leg of wearer whereby transferring the load of the backpack to the ground surface therefore reducing the weight of the backpack. The backpack exoskeleton also contains a shoulder strap and a waist belt, which also contribute to the load bearing functions of the backpack.

Backpacks, even those for outdoors sports, generally comprise an envelope of relatively flaccid textile material attached to a structured back-engaging frame, board or pad. Extreme sports such as skiing, motorbike racing, snow boarding, heli-skiing and such would benefit from greater protection to the person's back, as well as to the contents of the backpack. The disclosed backpack 2 includes a segmented and shaped back board 40 which permits limited flexing in certain directions to help protect the user's back from overextension. The container or packing portion 24 of the backpack 2 has corresponding rigid segments 16 interconnected by flexible textile portions 20. The segmented packing portion 24 and the segmented safety board 40 work together to protect both the contents of the backpack 2 and the back of the user.

A remedial hand wear article is for use by individuals who have suffered nerve damage which diminishes use of the hand. The article comprises (a) a glove for comfortably fitting onto a hand of an individual, (b) an enclosure permanently attached on the glove's top side and superimposed over at least one finger of the glove, and (c) a substantially rigid member positioned within the enclosure and contoured to follow the shape of a top of the individual's hand and to be operably associated with at least one finger of the individual to hold the at least one finger in a desired position and so that full finger flexure at proximal and distal knuckles is retained. The hand wear article is designed to remedy problems caused by different nerve damage in that one to five enclosure elongated sections are permanently attached over glove fingers depending on which finger(s) of the individual is affected by the damaged nerve. The glove portion of the hand wear article provides comfort to the user while also serving to lessen the noticeability of any hand or finger grotesqueness.

A football glove and method of use that protects a player's digits from hyperextending without impairing the player's ability to grasp objects and other players includes a hand covering portion for covering a palm and back of a user's hand. A plurality of form fitting finger receiving receptacles extend from the hand covering portion, and are in communication with the hand covering portion, each of the finger receiving receptacles includes a front and a back for receiving therebetween a finger of the user's hand covered by the hand covering portion. A unidirectional stiffener is fixed relative to at least one of the finger receiving receptacles adjacent the back of the at least one finger receiving receptacle, and extends toward the hand covering portion. The unidirectional stiffener is bendable toward the front of the at least one finger receiving receptacle to allow the user's finger to naturally curl toward the user's palm, and is substantially rigid in an opposing direction to prevent hyperextension of the user's finger.

The electronic unit is configured to receive a set threshold value on maximum squat count from a user. The electronic unit records the squat count and provide an alert when the squat count exceeds the set threshold value on maximum squat count to be performed by the user, thereby it prevents injuries caused due to over enthusiastic during the exercise session.

A brace for supporting a knee joint is disclosed which is specifically adapted to restrict lateral movement of the knee joint in addition to preventing hyperextension of the user's leg. The brace is formed by a rigid proximal member that fully covers the front and sides of the knee and extends partially over the tibia and a rigid distal member which overlaps the proximal member in the area of the knee joint while additionally extending over a portion of the upper leg of the user. The rigid members are attached together with a pair of hinge pins disposed on opposite sides of the knee with a primary pivot axis to allow bending of the knee joint. Attached to the inner surface of the proximal member is a knee pad which is used to provide a firm interface between the proximal member and the area of the knee joint. The knee brace further comprising at least two strap members attached to said shell members and extensible about the leg of the user.

A foldable drain pipe for draining effluent from a decanter in a settling tank in a water treatment system, comprising a plurality of pipe sections sealingly connected together end to end by pivotable elbow coupling pairs to form an articulated drain foldable in a vertical direction. The drain pipe is attachable at an upper end to the decanter and at a lower end to a tank outlet in the tank wall. The drain pipe can support its own weight and cannot come into contact undesirably with any other portion of the tank wall. The pipe unfolds upward as needed when the decanter and effluent level are high, and folds compactly between the decanter and the tank outlet when the decanter and effluent level are low. Multiple hobble apparatus options may be selected as defined herein to prevent rotational hyperextension of any of the elbow coupling pairs to assure that the pipe folds correctly.
