Systems, apparatus, and methods related to recreational balls with illuminated surfaces are described herein. In some embodiments, an apparatus includes an air-tight object having an outer layer and an inner layer. The opacity of the outer layer is greater than the opacity of the inner layer. The outer layer defines an aperture. Additionally, a light module is configured to send light from an interior of the air-tight object through the aperture of the outer layer.

A measurement system for use in an exercise machine, which exercise machine comprises a lifting mechanism and an engaging member for selectively engaging a number of stacked weights to the lifting mechanism, the measurement system comprising a pair of cooperating members including a range meter and a reflector member, wherein one of the cooperating members is connected to the lifting mechanism and the other of the cooperating members is connected to the engaging member, wherein the range meter is directed to measure a distance to the reflector member to determine a distance which correlates to the weight of the selectively engaged weights.

Embodiments of the present disclosure are directed to playground climbing structures that provide a pathway defined by a lower surface and bound on each side by a sidewall. The structures may comprise sensory play activities on the interior of the sidewalls as well as on the exterior of the sidewalls. The climbing structure is also adapted so as to be accessible to children of varying physical abilities, including for instance children with disabilities, such as by having at least one platform configured for access from a wheelchair or other mobility device and incremental adjustments in elevation that may be navigated by a child with limited mobility. Embodiments of the climbing structures are assembled from a plurality of components, which can be connected together in a variety of configurations to provide custom modular structures.

The present disclosure relates to systems and methods for elastic delivery, processing, and storage for wearable devices based on system resources. For example, a wearable apparatus may have at least one battery; at least one sensor configured to measure at least one property associated with a user of the wearable apparatus; at least one memory storing measurements from the at least one sensor and instructions; at least one transmitter configured to send data to a device remote from the wearable apparatus; and at least one processor configured to execute the instructions to: receive, from the at least one battery, an indicator of a charge; and based on the received indicator, sending a command to the at least one sensor to operate in a low-power mode or a high-power mode, the low-power mode having. a lower sampling rate than the high-power mode.

A golf club head has a body defining a ball striking face. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The body further defines a cover that extends over the void. The golf club head may further have support structures and adjustable weight members.

A system that wirelessly integrates actual drum equipment and singing equipment with a computer and the internet to allow musicians and or singers remotely located from one another to play music and or a competitive real or simulated music and or singing competition. An individual musician may opt to play music solo or practice to improve basic music, drumming, and or singing techniques. The system includes smart music and drum systems, an audio detection system, and drum motion sensing devices, all containing circuits and contact sensors or motion sensors, coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicating game performance information to a remote receiver-computer. The computer displays musician and or singing information, and visually simulates and controls a music and or a singing competition between two or more musicians, via the internet, having similar equipment and remotely located from each other. Standard drum sets may be retrofitted with the sensors and associated circuitry to convert such drum sets into smart drum sets for use with the system. Standard microphones may be retrofitted with the sensors and associated circuitry to convert such microphones into smart microphones for use with the system. The system employs specially developed computer software to process musician performance data, control the music competition, communicate music and information between musicians and or singers, generate and control visual simulations, and display singer and or musician performance information.

According to an embodiment, a device for recognizing a free weight training motion comprises a depth camera obtaining image information for measuring a user's body information before exercise and obtaining image information including a unique identifier attached to a piece of exercise equipment and motion of each joint of the user and a variation in body surface due to a motion of the body of the user doing exercise using the piece of exercise equipment, a sensor unit measuring a state of the piece of exercise equipment and recognizing the user, and a controller controlling the depth camera and the sensor unit and processing various pieces of information obtained by the depth camera and the sensor unit.

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 system for measuring a rower profile of a rower; the system comprising one or more sensors located on an oar for measuring one or more forces imparted on the oar by the rower in use at a predetermined time; one or motion tracking devices for determining a position of the oar in space at the predetermined time; a processing module for interfacing with the one or more sensors and a remote monitoring device; and determining the rower profile from the sensor data and the one or more motion tracking devices.
