Abstract: A hydraulic system includes a poppet control valve having an inlet workport, a function workport, a control chamber, and a poppet arranged between the inlet workport and the control chamber. The poppet is movable between an open position and a closed position. The hydraulic system further includes a pilot control valve. A pressure correlated to the function workport is supplied to a first side of the pilot control valve and a pilot source pressure is supplied to a second side of the pilot control valve. When a pressure in the function workport reaches a setpoint pressure, the pressure correlated to the function workport forces the pilot control valve to a position that increases a flow restriction between the control chamber and the function workport, so that the poppet moves in a direction toward the closed position and limits the pressure in the function workport to the setpoint pressure.

Abstract: Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Abstract: An offloading system for use with a treadmill includes an air chamber configured to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber and adapted to receive a user so that, in the operating condition, at least a portion of the user is received in the user seal and positioned within the air chamber, a pump operable to inflate the air chamber, and a controller configured to determine an occurrence of a loss of pressure in the air chamber and, in response to the occurrence, cause a reduction of speed of a running belt of the treadmill.

Abstract: An exercise and therapeutic device includes a treadmill comprising a running belt coupled to a treadmill frame and an offloading system coupled to the treadmill. The offloading system includes an air chamber surrounding the running belt adapted to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber, adapted to receive a user so that, in an operating condition, at least a portion of a user is received in the user seal and positioned within the air chamber and to seal the air chamber around the user, a pump operable to inflate the air chamber, at least one strap coupled to the treadmill frame and adapted to restrict the expansion of the air chamber and adjust a spacing of the user seal relative to a running surface of the running belt when the air chamber is inflated.

Abstract: A retainer with a closure mechanism not removable from the retainer is bonded to each of the air inlet openings of an inflatable convective thermal blanket. The bottom surface of the retainer is bonded to the blanket so that its orifice is in alignment with the opening into the blanket. The closure may be a flexible layer or sheet that is adhesively attached to the top surface of the retainer. An end portion of the flexible layer away from the orifice of the retainer may be press or die cut into the retainer so that the flexible layer is non-removably attached to the retainer when the user peels the releasably secured portion of the flexible layer away from the retainer to expose the air inlet opening. The closure can also be an extension of the retainer that is hingedly connected to the retainer so as to be able to be moved pivotally to cover the retainer. The closure has a configuration that allows it to be releasably secured to the retainer when it covers the orifice opening of the retainer.
