The present disclosure is directed to a non-intrusive, integrated system comprising an umpire bot for automatically monitoring, umpiring, scoring, analytics, learning and coaching for players while eliminating need for human umpires and scorers. The automated umpire bot with intelligent telescopic function monitors, cognitively recognizes and captures movements from all equipment's, analyses them, moves up and down and even avoid ball collision travelling towards it. The non-intrusive real time system captures all the game moments right from players initiation, toss of coin, commencement of game, monitoring field positions, keeping scores, umpiring decisions, overs, valid/in-valid deliveries, validating balls per over, wickets, catches, boundaries, sixes and displaying scores and statistics all throughout the game.

A retractable exercise rack system for efficiently securing an exercise rack against or near a wall when the exercise rack is not in use. The retractable exercise rack system may thus be adjustable between a retracted position against or near the wall, and an extended position which is distally-positioned with respect to the wall. The retractable exercise rack system generally includes a first support member a second support member, with an exercise bar connected between the support members. Wall mounts may be secured to the wall, with the first and second support members being adjustably connected to the wall mounts by linkages, scissor connectors, or arms. Latches and strikers may be utilized to releasably lock the support members in the extended and/or retracted positions. One or both of the support members may include a button for releasing the latches from the strikers.

Systems and methods for tracking off of the dribble shooting statistics are provided. An ejector launches basketballs to a user selected subset of pass receipt locations spaced apart about a basketball playing area. A controller receives data from an interface representing the user selected subset of the pass receipt locations and certain of the pass receipt locations in the subset where the player intends to perform a pre-shooting basketball move immediately before receiving the pass or making the shooting attempt and commands the ejector to launch at least one basketball to each of the pass receipt locations in the subset. Data is received from a detector indicating made basketball shots, and a performance report is generated with feedback for each of the pass receipt locations in the subset with a qualifier associated with at least some of the feedback indicating off of the dribble shooting.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A portable exercise system that can be attached to the uprights on any commonly available training rig, squat stand, or power rack, and for resistance can use any attachable weight. The system includes an upper pulley assembly, a lower pulley assembly and an anchor assembly. The anchor assembly utilizes a wedge and block to set the cable length and is adapted to attach the weights. The upper pulley assembly includes pulleys to keep the cable aligned and the resistance coming from above. The lower pulley assembly could be hinged for an additional degree of freedom. The cable runs through the lower pulleys, to the upper pulleys, and down to the anchor and weights. The other end of the cable has a fixed loop for attaching a handle for the user.

A rowing machine exercise device includes a vertically adjustable rear support base. The vertically adjustable rear support base includes an outer vertical support beam extending down from the rowing machine frame; an inner vertical support beam received in a telescoping manner within the outer support beam through the bottom of the outer support beam; a latch pin assembly mounted to the outer vertical support beam, where the latch pin assembly includes a latch pin biased to extend through the latch pin hole and any of the adjustment holes that are vertically aligned with the latch pin hole, and where the latch pin assembly includes an actuating tab that overcomes the bias to pull the latch pin from the vertically aligned adjustment hole when actuated; and a lift handle mounted to or part of the outer vertical support beam and/or the rowing machine frame.

A multifunctional chair is provided. The multifunctional chair includes a supporting body, a telescopic structure, a seat body, and a pedal assembly. The pedal assembly includes a fixing rod, a movable rod, an operation portion, and an elastic resistance member. The telescopic structure is connected to the supporting body and configured to be operated to telescopically move relative to the supporting body. One end of the fixing rod is fixed to the supporting body. The movable rod is movably connected to the fixing rod. The operation portion is arranged at an end of the movable rod away from the fixing rod. Two ends of the elastic resistance member are respectively connected to the supporting body and the fixing rod. A user can push against the operation portion to rotate the movable rod and the fixing rod toward the ground, and the elastic resistance member provides an elastic resistance.

A punching-training device is provided, including: a seat portion; a support portion, connected with the seat portion; a punched portion, connected with the support portion; and an elastic assembly, disposed on the support portion, the elastic assembly including a first elastic member and a second elastic member, at least one of the first elastic member and the second elastic member being movably relative to the support portion between a first position and a second position to change a relative position of the first elastic member and the second elastic member.

The rotator cuff exercise device includes a ring unit, a mounting board, and a pair of mounting tracks. The rotator cuff exercise device may be adapted to exercise joints and muscles or may prevent the loss of flexibility in an elbow or a shoulder blade. The rotator cuff exercise device may be particularly suited for therapy after an injury involving a rotator cuff. A handle may detachably couple to an individual rotatable ring selected from one or more rotatable rings of the ring unit and may be adapted to be grasped by a hand of the user. The handle may be operable to move the individual rotatable ring in a circular motion. The circular motion of the handle may exercise the joints and muscles of the user.
