Systems and methods for dynamic resistance training are provided that include the use of a dynamic force module. The dynamic force module includes an actuator and controller adapted to control the actuator according to a force profile that specifies the relationship between an operational parameter of the actuator and a measured parameter associated with a user performing an exercise. The dynamic force module is also capable of communicating with a broader network system to facilitate storing and distribution of force profiles and user profile information. The network system further includes features for, among other things, generating and managing force profiles, uploading multimedia content, and tracking user progress.

Embodiments described herein relate to methods, systems, and devices that can be leveraged to retrieve pickleballs from a court surface. More particularly, the present embodiments relate to a portable, light-weight, hand-held pickleball collector.

To provide a highly reliable, cost-effective traveling collector that can determine the positions of fallen objects, such as balls, on the ground using a simple method, or determine the correct positions of fallen objects, such as balls, on the ground only by improving software and without the need for significant changes to hardware. The traveling collector includes a count sensor as a sensor for detecting the position of each collected ball at a position detected by a satellite positioning system, for example. A controller determines a position, which is obtained by reflecting, based on the positional information on the ball collector at a time point when the ball was counted by touching the count sensor, the movement distance of the ball collector from the time each ball was picked up from the ground by a ball collection wheel till the ball was counted by touching the count sensor in a direction opposite to the traveling direction of the ball collector at that time, as the actual position where each ball was picked up.

A golf ball having a compressible core with an RFID tag embedded therein is described. The compressible core comprises an outer core that surrounds an inner core and the RFID tag. The outer core has a hardness that is greater than the inner core. The RFID tag is composed of a planar carrier, a planar RFID integrated circuit, and an RFID antenna. The RFID integrated circuit includes a memory that stores at least one unique identifier. The RFID antenna is electrically coupled to the planar RFID integrated circuit. The planar carrier includes a first carrier surface that is parallel to a second carrier surface, and the planar carrier receives the RFID antenna and the RFID integrated circuit on the first carrier surface to form the RFID tag. Additionally, the molded shell encapsulates the compressible core.

A golf club head has a body defining a ball striking face. The body further has a rear portion comprising a plurality of side walls and a planar lower portion. The plurality of side walls extend downward from a top of the golf club head towards the planar lower portion. The body further comprises a cover extending over the rear. The body further defines a gap between the cover and the planar portion.

Methods, systems, and techniques for automated detection of goals and announcement of same are provided. The system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and, when an infrared signal is received, the microcontroller automatically triggers one or more annunciator devices, such as visual, auditory, or haptic devices, to automatically indicate that a goal has been scored without human intervention.

The present invention relates to an elastic band apparatus for assisting a human user in properly aligning body members during exercise, supporting a head of a user when lying down during exercise, and angling at least one elastic band at a predetermined angle. In order to do so, an elastic band apparatus is provided having a platform, at least two handles extending outward from the front surface of the platform and at least one slot arranged through the platform.

A system and method of linking a product to product information comprises a physical product configured for use by a user and a scannable identifier associated with the physical product. The scannable identifier is accessible to the user, and the scannable identifier is configured to cause a user device to navigate to content related to use of the physical product in response to scanning of the scannable identifier with a scanning sensor associated with the user device.

A system for recognition of objects in a game, the system has a table with playing board for pucks on which the game is played, and reference markings distributed across the playing board that are used together with corner of the playing board in a surface mapping process. At least one area scan camera acquires images of the playing table during a game and reads fiducial marker of pucks that have the fiducial markers. The at least one area scan camera is arranged to cover the playing board and the reference markings. A processing unit processes the images acquired by the at least one camera.
