A self-powered apparatus is used for various kinds of cycling and indoor exercise devices. The self-powered apparatus includes a pedal unit, a spindle, a generator and an energy storage element. The pedal unit includes an inner surface to form an accommodating space therein. The spindle is accommodated in the accommodating space. The generator includes a stator and a rotor. The stator is disposed on the spindle, the rotor is disposed on the inner surface of the pedal unit, and the rotor surrounds the stator correspondingly and is non-contact with the stator. The energy storage element is electrically coupled to the generator. When the pedal unit is being pedaled to rotate by a rider, the stator is fixed on the spindle, the rotor rotates relatively to the stator and along with the pedal unit, and a power is generated by the generator to charge the energy storage element.

According to one example, a training device includes a first set of time of flight sensors (ToF) positioned to face in a first direction, a plurality of addressable red, green, blue light emitting diodes (RGB LEDs) positioned to face in the first direction, and a second set of ToF sensors positioned to face in a second direction that is perpendicular to the first direction. The training device includes and/or is in communication with one or more processors that can determine a training program for a user that includes visual signals that represent a plurality of actions for performance by the user. Also, for each of the plurality of actions, the training device can cause a first set of the plurality of addressable RGB LEDs to provide a visual indication of the corresponding action for performance by the user, and detect whether the user performed the corresponding action.

The present invention relates generally to a bat hanger device comprised of a base plate with at least two curved protruding arms that secure a baseball bat vertically in the air. The base plate of the device also has at least one continuous opening that can be received by at least one clip, that allows the device to be secured to a chain-link fence. One embodiment of the device may also comprise at least one magnet in the base plate, which further aids in securing a baseball bat on the device. Accordingly, the device retains a baseball bat in a position above a ground surface and away from the fence to which the device is attached.

In one example, a muscle exercise device includes a first arm, a second arm rotatably connected to the first arm, and the second arm and first arm configured to cooperatively define a recess. The muscle exercise device also includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm, and a wireless transmitter disposed in either the first arm or the second arm, wherein the wireless transmitter is responsive to communications from an app residing on a user device.

A system for use in personal fitness can include: an article of clothing configured to be worn by a user during a personal fitness session, the article of clothing having a fabric layer and at least one weighted portion formed by either or both polyurethane (PU) and thermoplastic polyurethane (TPU) printed on the fabric layer; an electronic device having a processor; and a communication unit integrated with the article of clothing and configured to interact with the electronic device, wherein the communication unit includes a near field communication (NFC) device or a QR code, and further wherein the processor is configured to launch a personal fitness application responsive to the user interacting with the NFC device or QR code.

A tactical board includes embedded magnets secured therewithin the tactical board. A transparent cover overlays the magnets and substrate. A stylus is provided to manipulate the position of the magnets on the substrate. The tactical board preferably includes indicia in the form of common sorts playing surfaces or the like.

The present disclosure is directed to an exercise mat including a base layer, the base layer defining a recess therein configured to receive a cartridge holding paint and a painting surface, a top layer operatively connected to the base layer, at least one magnet or other fastening mechanism embedded within the base layer, and at least one magnet embedded within the top layer.

A surfing simulation device can be wirelessly connected with virtual reality (VR) glasses. The surfing simulation device includes a surfboard, a surfboard base, and a controller disposed in the surfboard base. The controller controls the actions of the surfboard based on scene information associated with a surfing scene displayed in the VR glasses, such that the actions of the surfboard are synchronous with the surfing scene displayed in the VR glasses. The surfboard of the surfing simulation device can make simulating actions in real time by synchronizing with a surfing scene displayed in VR glasses, such that users can experience the immersive feeling.

A holder for securing golf accessories therein and attaching to a belt, golf bag, waist band, piece of clothing or other article that is carried while golfing. The holder includes a housing having a base and a sidewall extending from the base toward an open face defining a compartment that can receive a ball divot repair tool. The sidewall forms a perimeter of the housing, wherein the open face extends the perimeter to allow the ball divot repair tool to be quickly and conveniently removed and inserted therefrom. A divot repair tool fastener is disposed on a surface of the housing to secure the ball divot repair tool thereto. In some embodiments, the divot repair tool is included and comprises a ball marker that is interchangeable with other ball markers in order to allow for a variety of colors or embodiments to be displayed on the divot repair tool.

The present disclosure includes apparatuses, devices, and systems for use and handling of sporting accessories, such as golfing equipment. Some of the systems may include a golf bag having an integrated magnetic plate that extends along a first side of the golf bag and is configured to interact with a first magnetic field, a magnetic hub configured to interact with a second magnetic field, the magnetic hub configured to be coupled to the golf bag via a fastener; a magnetic holder configured to hold a first golf accessory such that the first golf accessory is secured to the golf bag while the magnetic holder is coupled to the magnetic plate or the magnetic hub, or combination thereof.
