The described embodiments relate to systems, methods, and apparatuses for providing an adjustable amount of tension to various portions of a body of a user. The tension can be exhibited by cables that extend from the body mounted device. The cables can be routed through a pulley assembly located with cables guides of the body mounted device. A user can adjust the tension of the cables using knobs located at the ends of the cable guides. The cables can terminate at bands, which can be attached to appendages of the user during training. When the user is wearing the body mounted device, a mounting plate of the body mounted device can conform to the shoulders of the user, and a separate plate of the body mounted device can be depressed against a back side of the user.

A swing analysis method includes acquiring measurement data measured by an inertial sensor in a swing motion with a golf club, and calculating torque data indicating a temporal change of a torque exerted on the golf club by analyzing the measurement data using a head speed coordination system having a first axis including a speed vector of a head of the golf club, a second axis being orthogonal to the first axis and extending along a shaft of the golf club, and a third axis orthogonal to both the first axis and the second axis.

This disclosure relates to a relatively compact smart ball launching system and associated methods for using the same. In various embodiments, the disclosed ball launching system may comprise a collapsible ball hopper that can store a larger number of balls while maintaining a relatively compact size. In certain embodiments, brushless motors may be used to improve power efficiency while allowing for accurate launch speeds and/or spins. In some embodiments, a pre-launch chamber may be included in a ball dispensing mechanism that may facilitate on-demand shots and/or power savings by shutting the ball launching system down when the ball hopper is empty. In further embodiments, the ball launching system may be controlled, at least in part, via a mobile device. In some implementations, the ball launching system may include and/or otherwise interface with a camera system to facilitate improved calibration and/or record user actions.

Disclosed is a posture coaching method for weight training, which includes sensing an exercising motion of a user by a sensor module that is attached to a part of the body of the user or exercise equipment gripped by the user for exercising; calculating an inherent angle of the sensor module and a linear acceleration of each axis of a user-based coordinate system based on the user by using the sensed value; analyzing an exercising posture of the user by detecting and classifying a pattern of the linear acceleration and the inherent angle; and generating exercising posture correction data based on the classified pattern.

Systems and methods for identifying a condition of a user. A treatment apparatus is configured to be manipulated by the user for performing an exercise, and an interface is communicably coupled to the treatment apparatus. One or more sensors are configured to sense one or more characteristics of an anatomical structure of the user. A processing device and a memory is communicatively coupled to the processing device. The memory includes computer readable instructions, that when executed by the processing device, cause the processing device to: receive, from the sensors, one or more sensor inputs representative of the one or more of characteristics of the anatomical structures; calculate an infection probability of a disease based on the one or more characteristics of the anatomical structures; and output, to the interface, a representation of the infection probability.

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 ground traversing, electrically driven drone travels along a preprogrammed path that corresponds to pass catcher's travel path during a play, matching the pass catcher's speed and run cuts. The play is wirelessly communicated to the drone by a handheld electronic device located remote of the drone. A target is located on the drone so that a quarterback can throw a football at the target in order to refine the quarterback's timing and accuracy for the play. Sensors onboard the drone track both the football's and quarterback's speed and travel trajectories so that such data can be collected, along with the drone's travel path, and stored onboard the drone's control unit and eventually fed into 3-D reconstruction software for analysis by the quarterback and coaching staff. The target rotates so that the target either faces in a fixed direction or constantly faces the quarterback during execution of drone's maneuvers.

A gymnastic machine for weightlifting includes: a load-bearing frame, two opposite first lateral guides, upward-downward, developed according to a first direction, two first slides each slidingly constrained on a corresponding first lateral guide, two opposite second lateral guides, developed according to a second direction transversal to the first direction, and each defined on board of one of the first slides, two second slides each slidingly constrained on a corresponding second lateral guide, a lifting bar, each of the ends of the lifting bar being constrained to a corresponding second slide, a motorised transmission configured for applying to the first slides either an opposing force to an upward thrust force, or a downward traction force.

A training device and a training method for reducing hypertonic are disclosed. The training device includes a base, a driving circuit, two pedals, a control circuit, and a switch circuit. The driving circuit is fixed on the base. Each of the two pedals is coupled to the base. The driving circuit drives each of the two pedals to swing repeatedly between a first position and a second position relative to the base. When the control circuit executes a training program, the control circuit actuates the driving circuit.
