A stepper exercise machine includes a machine body, a pedal linking rod, a pedal, a connecting assembly, a sliding rod, a sliding rod adjustment assembly, a connecting support, and a base. When in use, by adjusting the sliding rod adjustment assembly, the inclination angle of the sliding rod is adjusted, and the gradient for the pedal to be moved on the sliding rod is also adjusted, that is, the motion trajectory and exercise intensity of the stepper exercise machine is adjusted, thereby increasing the scope of use of the stepper exercise machine and meeting the diversified needs of the user.

A periodic mesoporous organosilica (PMO) nanoparticle functionalized nanocomposite membrane (NCM) for membrane distillation, the NCM including: polymer fibers such as polyetherimide fibers aggregated into a matrix; and hydrophobic PMO nanoparticles disposed on the polymer fibers. The PMO nanoparticles include a framework connected by organic groups and pentafluorophenyl groups. Good membrane flux and anti-fouling was demonstrated. Membranes can be prepared by electrospinning.

A treadmill includes a platform where the platform includes a first side panel and a second side panel spaced apart at a distance from the first side panel, and a gap defined between the first side panel and the second side panel. The treadmill also includes a running deck contained within the platform and exposed within the gap, a first pulley connected to the running deck, a second pulley connected to the running deck opposite the first pulley, a tread belt surrounding the first pulley and the second pulley, a first post removably connected to the platform, a second post removably connected to the platform, and a first rail transversely connected to the first post and the second post.

The invention concerns exercise apparatus having a weight source (18) operably connected to a plurality of manual actuators (28, 32) by a cable and pulley system. The cable and pulley system (12) has a plurality of pulley wheels (16), a supporting frame (10) for the weight source (18) and pulley wheels (16), and a cable (22) defining a force path from the weight source (18) over the pulley wheels (16). The pulley wheels (16) and frame (10) are provided in a common plane with the weight source (18) at least when the exercise apparatus is not in use. The manual actuators (28, 32) are provided at spaced locations along the path defined by the cable (22) and are actuatable in a direction away from the common plane when in use. The frame (10) may supported in an upright orientation for use by a support structure, e.g. a wall, and may occupy a minimal space/depth.

A stepping exercise machine includes a base and a pedal. The base is provided with an undulating slide rail. A top end of the slide rail is defined as a peak. Bottom ends of two sides of the peak are defined as troughs. The two sides of the peak or the bottom ends of the troughs are provided with stop blocks, respectively. An underside of the pedal is pivotally connected with rollers. Two sides of the underside of the pedal are fixedly connected with a pair of stretchable elastic members. The other ends of the pair of stretchable elastic members are fixed to two sides of the base. The rollers support and drive the pedal to reciprocate along the undulating slide rail ups and downs by means of the stretchable elastic members.

A composite motion exercise machine includes a control panel which provides a plurality of movement modes and allows a user to issue a command to change the configuration of linkage units of the exercise machine to have the machine perform a movement mode without manual adjustment, so that the pedal of each linkage unit can be moved along a closed trajectory. The control panel also allows the user to finely adjust the trajectory and the resistance associated therewith. The trajectory performed by each pedal of the exercise machine is ergonomic so that the user can be protected from exercise injury.

The present invention relates to the field of wearable robotic devices that physically interact with humans, and in particular refers to a wearable exoskeleton, in particular for the upper limb. The invention refers to an electro- or magneto-rheological fluid type semi-active joint purposely conceived to be used to make the exoskeleton. It comprises a first body and a second body, slidably coupled to each other, with a flow mode rotating configuration, which allows to have a fluid flow moved by a pressure gradient induced by the circular movement of a piston in a chamber, with constructive simplicity and decrease of wear.

A system may include a receiving module and a conversion module. The receiving module may be for receiving location data associating video data depicting a real-world route with topographical location of the real-world route. The conversion module may be for creating an exercise program. The exercise program could include control signals representing changes to be made to one or more operating parameters of an exercise device as the video data depicting the real-world route is displayed to a user of the exercise device. The control signals may be based at least in part on the location data. The changes to the one or more operating parameters may correspond at least in part to one or more aspects of the real-world route.

A free weight assembly includes a cradle, an aerobic exercise element that is movable with respect to the cradle during the performance of an exercise, at least one free weight removable from the cradle, an input in communication with a processor that determines a time to instruct a user to remove the free weight, and an indicator that activates when the time to remove the free weight arrives.
