Abstract: An exercise machine which is capable of having its lift, roll, or pitch adjusted with respect to a base so as to provide a plurality of positions of the exercise machine with respect to the base. The exercise machine generally includes a base and an exercise machine movably connected to the base. The exercise machine may include a track, a carriage slidably connected to the track, and a biasing member attached to the carriage to apply a resistive force to the carriage. A plurality of actuators may be connected between the base and the exercise machine. The plurality of actuators may be utilized to adjust a pitch angle or a roll angle of the exercise machine with respect to the base. The plurality of actuators may also be utilized to lift or lower the exercise machine at a constant angle of pitch and/or roll inclination.

Abstract: Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include: providing a thrombus extraction device including a proximal self-expanding member formed of a unitary fenestrated structure, a distal substantially cylindrical portion formed of a net-like filament mesh structure, and an inner shaft member connected to a distal end of the net-like filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction; retracting the thrombus extraction device to separate a portion of the thrombus from the vessel wall and to capture the portion of the thrombus within the net-like filament mesh structure; and withdrawing the thrombus extraction device from the body to remove thrombus from the patient.

Abstract: An adjustable control link for transferring rotor shaft rotation to a rotating swashplate, the adjustable control link includes an elongate element rotatable with the rotor shaft, the elongate element having a first end. A structure has an opening and a second end. At least one cam component is disposed within the opening and is rotatable relative to the structure about a central axis of the opening. A pin is configured to couple the elongate element to the at least one cam component. The pin is eccentrically rotatable about the central axis to move the first end of the elongate element relative to the second end of the structure.

Abstract: A tunable mass damper assembly is attachable to a rotor blade. The tunable mass damper assembly comprises a base configured to be attached to the rotor blade and a pendulum mass structure movably attached to the base and configured to move relative to the base in accordance with a rotational speed of the rotor blade about a rotor axis. The pendulum mass structure is configured to reduce vibratory forces of the rotor blade induced by a rotation of the rotor blade about the rotor axis. An entirety of the pendulum mass structure being configured to be contained within and enclosed by the rotor blade.

Abstract: An upgrade arrangement wherein the switching functions of an in-service switch or cross-connect system are transferred or "re-homed" onto a new, larger capacity switch via the existing input and output ports of the original system. The re-homing can be performed without loss of service, even if the original system is operating at full-capacity. By exploiting the protection redundancy engineered into existing telecommunication switching systems, all of the signals being routed through the original switch are temporarily consolidated onto only one-half of the switching fabric normally required to accommodate such connectivity. This signal consolidation allows half of the original switch ports to be brought off-line (without a service disruption), and linked to the new, higher capacity switching fabric.

Abstract: Aqueous solutions of partial hydrolysates of algae, optionally labelled with stable isotopes, are used as growth media for cells.

Abstract: The vanes of a radial turbine have pressure surfaces which are convex when viewed in a plane normal to the axis of rotation of the radial flow rotor and suction surfaces which are concave when viewed in the same plane. The curvature acts to promote favorable radial surface pressure gradients to assist the control of boundary layer migration in the intervane passages and also increase the structural integrity of the vane members. The otherwise flexible extremities of the vane members are stiffened by introducing the curvature, as the natural resonant vibration frequencies of the vanes are changed. The invention is also applicable to the vane members of a radial or mixed flow impeller in gas or other fluid applications.

Abstract: To minimize secondary losses and flow maldistribution, an aerofoil such as a gas turbine nozzle guide vane, is designed so that in the throat defined by the trailing edge of one aerofoil and the flank of the adjacent aerofoil, the local gas flow streamlines are normal to the trailing edge of the aerofoil at the point of intersection.
