Abstract: A treadmill assembly that includes a frame and a treadmill belt. In addition, a sensor produces a signal representative of an aspect of the user's position relative to at least one point on the frame. A belt rotation assembly turns the belt with a speed related to the signal. In one preferred embodiment the speed of the belt is inversely proportional to the distance between the user and the front of the treadmill. In another preferred embodiment the treadmill is sized to support a cycle.

Abstract: The present invention is a device to simulate balance and motion activities of a user in response to the user's movements. The device has a curved sloping base with a top central area, a user support portion with a top and a bottom, a plurality of rolling elements coupled to the bottom of the user support portion, and a resilient element biasing the user support portion towards the top central area of the curved sloping base. The orientation of the user support portion relative to the top central area of the curved sloping base is responsive to movements of the user. The device provides a simple easy to use way to simulate balance and motion activities and thus condition and train a user conveniently and efficiently. The device conditions muscles in the legs and trunk as well as the balance mechanism while increasing endurance.

Exercise devices, such as resistive elements, may be connected to the tower and/or the platform at various points of connection for performing a variety of exercises.

Abstract: This invention relates to a whole body vibrator platform which is attachable to a treadmill. The treadmill belt provides the power to move the platform, translating the horizontal, linear, belt movement into vertical oscillations through one or more eccentrically mounted rollers which support the platform. A person standing on the vibrator platform experiences a vertical vibration at frequencies established by the linear velocity of the treadmill belt.

Abstract: A rotary rehabilitation apparatus is presented for rehabilitation of a person's extremity, including the joints and assorted muscles, tendons, ligaments, that can be tailored to the person's needs based upon their physical size, type of injury, and plan for recovery. The apparatus facilitates the adjustment of the range of motion of the user's extremity in a cycling action by offsetting a moveable lever from a fixed lever at a plurality of angles. As the user's extremity moves in a circular path, the extremity engages in extension and flexion to cause movements in the articulations formed at the user's joints.

The bench further includes left and right leg support sections, pivotally coupled to the torso support section, to support at least the user's thighs. The apparatus also includes a coupling member extending forward from the base, and configured to interchangeably couple with an exercise module.

Abstract: A method and apparatus for increasing locomotor muscle size and strength at low training intensities using eccentric ergometry.

Abstract: The invention concerns an improved hydrocracking process having a step for eliminating polyaromatic compounds from at least a portion of a recycled fraction by adsorption on a particular adsorbent based on alumina-silica with a limited macropore content.

Abstract: A bicycle simulation apparatus includes: a steering angle sensor which detects a steering angle of handlebars; a visual display which displays scenes based on a simulated travel speed and the steering angle of the handlebars; and a crank position detector which detects rotational positions of cranks. The crank position detector includes two detected protrusions on a crankshaft and left and right approach sensors. A warning section of a main controller issues warnings if it is determined that the steering angle exceeds a predetermined angle to the left or right during simulated traveling, and if it is also determined by the crank position detector that the crank is directed downward during a sharp turning operation of the handlebars. The bicycle simulation apparatus enables a more realistic driving simulation in consideration of rotational positions of simulator pedals and cranks.

Abstract: A swimming simulation system is provided, aspects of which include a dynamic bench, an arm cable pulley system coupled with hand grips, a foot cable pulley system coupled with a foot hold, and a resistance mechanism with attached gearing systems. All of the assemblies are operatively connected to a support frame. A user may lay face forward on the dynamic bench, or on their back on the dynamic bench, and pull the hand grips and/or foot holds to simulate swimming. The dynamic bench comprises a fixed center portion and independently rotatable sides that are interconnected at an interior edge to the fixed center portion and to biasing members at a point away from the interior edge. The side portions move independently of each other and provide a simulation of the yaw a swimmer experiences while swimming.

Abstract: A training bench for cyclists includes a framework. The framework has rollers on which the wheels of a bicycle rest. The framework also has a central support including a platform which is connected to the framework with transverse bars, on which it can move. The platform has an elastically deformable anchoring system serving as a holding base for holding a column. At its free end, the column supports the frame of the bicycle. The anchoring system acts as an absorption member for controlling the movement of the bicycle with regard to the platform and the framework.

Abstract: An integrated folding mechanism of a treadmill having a slide pusher supported by a pneumatic cylinder at the bottom of a platform frame thereof.
