A portable pitching mound that offers the strength and durability of a traditional dirt mound that is compatible with turf fields and will not create an edge lip on a baseball field.

A pole vault swing-up rack includes a frame body with upper hooks and a lower push bracket. The rack is designed to hang vertically from a horizontal bar—as a pull-up bar—by the hooks. An athlete hanging from the pull-up bar in an upright vertical position may kick his/her legs and torso up to an inverted vertical position to simulate movement of a pole vault. The athlete's shoulders rest against vertical uprights of the rack to maintain the athlete's shoulders and body in front of a vertical plane as in a pole vault movement. A trainer can use the lower push bracket to assist the athlete in the kicking motion. The parts of the rack that come into contact with the athlete may be covered in foam padding and a rubber coating.

Enclosures for facilitating activities in space, and associated systems and methods, are disclosed. A representative system includes a spacecraft having an enclosed interior volume (which can be formed by an inflatable membrane) and one or more unmanned aerial vehicles (UAVs) carried by the spacecraft and positioned to deploy into the enclosed interior volume. The system can include a remote-control system to control the one or more UAVs from a terrestrial location while the spacecraft is in space. A wireless charging system can provide electrical power to the one or more UAVs. A representative method includes configuring one or more controllers to launch a first spacecraft to a first orbit, launch a second spacecraft to a second orbit, move the first spacecraft to the second orbit, dock the first spacecraft with the second spacecraft, and broadcast an event within an interior volume of the first spacecraft to a terrestrial location.

A self-contained, portable and retractable apparatus is described that transforms a sufficient smaller space into a suitable place, either indoors or outdoors, where a large space is unavailable, into a practice facility for sporting activity skills. This backdrop apparatus allows practice of hitting or throwing of a ball or other object in a contained environment and may also be used for virtually playing at any famous location.

A mobile-exercise trailer includes a platform having at least one exercise equipment arranged thereon. Two sidewalls each have a first end joined to the platform, and at least one of the two sidewalls has a window. A first door is arranged to cover the window in at least one sidewall. A roof is attached to a second end of each of the two sidewalls, and a first power rack is retractably extendable from one of the two side walls. Attachment strips may be arranged on one of the two sidewalls. At least one of dip bars, wall ball targets, a punching bag, and a virtual weight pulley machine can be connected to the attachment strips. Video monitors are arranged on at least one of the two sidewalls. Two wheels are axially arranged below a portion of the two sidewalls, and a manual and/or remote controlled trailer dolly extends from a front of the mobile-exercise trailer.

A trampoline comprising a trampoline mat defining a jumping area and supported via springs from a circumextending support structure, the support structure including a plurality of legs so that the trampoline mat is positioned at a height above ground or flooring; the trampoline being provided with a safety enclosure surrounding the jumping area. The safety enclosure comprises a net supported by a plurality of telescopically extendable poles, each pole when extended comprising a plurality of sections, each successive extended section with distance above the trampoline mat having a cross-section less than that that of the next less extended section whereby the sections nest when telescopically collapsed. The lowermost such section is supported at a position above the ground or flooring by the support structure.

The disclosure provides a badminton net rack, comprising a base, has an grounding side and a mounting side opposite to each other, the base comprises two seat bodies, a support rod connecting the two seat bodies, and a connector spanning the support rod, the connector comprises a first stuck part and a second stuck part, the first stuck part is used for stuck badminton racket; two telescopic rods, can be switched between an inverted trapezoidal state and a stuck state, in the inverted trapezoidal state, the two telescopic rods are respectively connected to the two seat bodies to form an inverted trapezoidal structure for installing a ball net, in the stuck state, the two telescopic rods are respectively stuck to the two second stuck parts of the connector. The above-mentioned badminton net rack has various functions, is more portable and has better stability.

A basketball training system includes a server computer and a basketball training machine. The server computer executes a workout module that manages operation of a graphical user interface that presents a graphical representation of a portion of a basketball court and receives user inputs that define a workout program that includes selected ball delivery locations relative to the visual representation. The basketball training machine receives the workout program and delivers basketballs to the selected ball delivery locations.
