The present invention is a portable rowing machine that allows a user to perform rowing, skiing, paddling, or any other physical activities at any suitable location. The portable rowing machine contains a housing, a pulley, a flywheel, a planetary gear assembly, an anchor, a retraction mechanism, and a pull cord. The housing contains a central gear support. The pulley, the flywheel, the planetary gear assembly, and the retraction mechanism are positioned within the housing. The central gear support is positioned within the housing. The planetary gear assembly is positioned within the central gear support. The pulley and the flywheel are axially connected opposite to each other along the planetary gear assembly. The retraction mechanism is operatively connected to the pulley, where the retraction mechanism is configured to retract the pull cord into a spooled state around the pulley. The anchor is externally connected to the housing.

A mobile molding system, comprising a vehicle and one or more molds arranged on the vehicle configured for receiving one or more expandable nonwoven substrates, heating said one or more expandable nonwoven substrates so as to cause said one or more expandable nonwoven substrates to expand and fill the one or more molds with one or more expanded nonwoven containing articles of three dimensional shape, and releasing said one or more expanded nonwoven containing articles of three dimensional shape from the one or more molds is provided. Methods for manufacturing three dimensional objects using the mobile molding system are also provided.

An apparatus comprising a practice device for practice of hitting a tennis ball includes a server configured for serving the tennis ball to a user, a net disposed to intercept a flight of the tennis ball after the tennis bell has been hit by the user using a racket and to direct the captured tennis ball back towards the server to be served again to the user, an image detector configured to observe the tennis ball as the tennis ball hurtles towards the net, and a processor. The processor determines, based at least in part on image frames received from the image detector, data indicative of the tennis ball's virtual landing spot. This virtual landing spot is an estimate of where the tennis ball would have landed on an opposing court had the tennis ball not been intercepted by the net.

A barbell rack (1) installable on a wall, comprising: a first upright (2) and a second upright (3) fixable to the wall and distanced from one another; a first pole (5) and a second pole (6) respectively associated to the first upright (2) and second upright (3), each of said poles (5, 6) having a plurality of holes (7) adapted to receive a support shelf (8), means for hinging (9; 10) each pole (5, 6) to the corresponding upright (2, 3) in such a way that each pole (5, 6) is movable between a use position, in which it is at a maximum distance from the corresponding upright (2, 3), and a rest position, in which it is at a minimum distance from the corresponding upright (2, 3).

An indoor golf tee includes a tee base and a tee shaft. The tee base has a base top portion and a base bottom portion. The base top portion has a connecting hole therethrough. The tee shaft has a shaft top portion, a shaft bottom portion, and a shaft body. The shaft body is connected between the shaft bottom portion and the shaft top portion. The shaft top portion is configured to hold a golf ball thereon. The shaft bottom portion is removably connected in the connecting hole of the tee base in a perpendicular orientation to the tee base. When the base bottom portion of the tee base is positioned on a surface, and the shaft bottom portion is connected in the connecting hole of the base top portion, the tee base orients the tee shaft in the perpendicular orientation to the surface.
