A smart collar for a weight lifting bar includes: a body defining a passage for receiving the weight lifting bar; a sensor coupled to the body for sensing motion of the body and generating data related to the motion; and, a processor coupled to the body for receiving the data from the sensor and for processing the data for at least one of storage and transmission.

A training system includes a launching device house a computer electrically connected to a mechanical hopper and a plunger disposed within a casing sized to launch a lacrosse ball. The casing is structured and arranged to be movably connected to the housing such that at least one of a launch angle, speed, direction, distance and spin can all be selectively chosen by a user. At least one sensor is designed to be placed onto at least one of a player, the lacrosse ball, or a lacrosse net such that the sensors are structured and arranged to relay metric data to the computer in connection with a training program software operating on the computer, wherein the sensor(s) are wirelessly connected to the computer. A mobile device software application communicates with the computer for tracking the metric data and selective programming of the lacrosse ball tossing and training system by the player.

A balance and/or gait perturbation system is disclosed herein. The balance and/or gait perturbation system includes a balance and/or gait perturbation device and a data processing device. The balance and/or gait perturbation device includes one or more displaceable components configured to be displaced at a plurality of different positions, and having one or more surfaces for receiving one or more respective limbs of the person; and one or more first actuators coupled to the one or more displaceable components to adjust the displacement position of the one or more displaceable components. The data processing device is configured to generate a stochastic signal for introducing a perturbation to the one or more displaceable components, and to control the displacement position of the one or more displaceable components using the stochastic signal such that the one or more displaceable components perturb a balance and/or gait of the person.

Tracking and monitoring athletic activity offers individuals with additional motivation to continue such behavior. An individual may track his or her athletic activity by completing goals. These goals may be represented by real-world objects such as food items, landmarks, buildings, statues, other physical structures, toys and the like. Each object may correspond to an athletic activity goal and require an amount of athletic activity to complete the goal. For example, a donut goal object may correspond to an athletic activity goal of burning 350 calories. The user may progress from goal object to goal object. Goal objects may increase in difficulty (e.g., amount of athletic activity required) and might only be available for selection upon completing an immediately previous goal object, a number of goal objects, an amount of athletic activity and the like.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

An Internet of Thing (IoT) device includes a sensor coupled to a processor; and a transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

The disclosed physical exercise apparatus (2) comprises a frame (2′) equipped with a crankset and a saddle (26), the saddle itself comprising a chassis (262) fastened to the frame, two saddle parts (266) and articulation members (267, 268) for articulating each saddle part relative to the frame around a pitch axis (A26), about a roll axis (B26) and about a yaw axis (L26). This apparatus (2) also comprises sensors (30, 50) for detecting a pitch movement (T), a roll movement (R), and a yaw movement (L) of each saddle part respectively about the pitch, roll, and yaw axes, these movements resulting from pedaling made by a user. At least one calculation unit (40) is configured to determine, from output signals (S.sub.30, S.sub.50) of the sensors, angular amplitudes (α, β, γ) of the pitch (T), roll (R), and yaw (L) movements. At least one screen (29) is provided in order to display, depending on the angular amplitudes determined by the calculation unit (40), the position on each saddle part of a bearing point (P.sub.G, P.sub.D) of an ischium of a user in the process of pedaling.

A locking device for an exercise system may include at least one moveable assembly that is in communication with a resistance mechanism. The locking device has an actuating device for selectively engaging the locking device, a locking member having a contact portion, wherein the contact portion of the locking member is not in contact with the resistance mechanism of the exercise system when the actuating device is in a first position, thereby allowing movement of the at least one moveable assembly, and wherein the contact portion of the locking member is in contact with the resistance mechanism of the exercise system when the actuating device is in a second position, thereby preventing movement of the at least one moveable assembly.

An elliptical exercise device has a frame and guide link pivotally attached thereto. A foot support link is pivotally connected to a lower attachment point of each guide link so that when the guide links pivot relative to the frame, foot receiving areas of the foot support links move in a path of travel having a horizontal component of motion. A cam drive has cams supported for rotation about an axis of rotation and pivoting arms each engaging one of the cams such that rotation of the cams causes movement of the pivoting arms. Flexible elements couple the foot support links to the pivoting arms such that rotation of the cams moves the foot receiving areas of the respective foot support links in a path of travel having a vertical component of motion.

The disclosure is directed at a system and method of automated object launching, for replicating ball trajectories, for example with a baseball. The system receives an input from a user that includes trajectory information and then launches an object based on that trajectory. The system includes subsystems that control the orientation of the object to be launched and the position of the system itself. The system also includes a results tracking database to provide analytics and the like for the user.
