An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

The scorekeeping system includes a plurality of scoring elements. An upper bracket can be secured a first string having a first portion of the plurality scoring elements and a second string having a second portion of the plurality of scoring elements. The first string can have a first thread and a second thread, each of the first thread and the second thread being threaded through the first portion of the plurality of the scoring elements. The second string can have a third thread and a fourth thread, each of the third thread and fourth thread being threaded through the second portion of the plurality of the scoring elements.

Provided is an apparatus, method, and system for simulating a defender of a sport activity.

A basketball training system includes a server computer and a basketball training machine. The server computer executes a workout module that manages operation of a graphical user interface that presents a graphical representation of a portion of a basketball court and receives user inputs that define a workout program that includes selected ball delivery locations relative to the visual representation. The basketball training machine receives the workout program and delivers basketballs to the selected ball delivery locations.

An exercise training system is provided having a system controller and a plurality of stimulant target units connected via a wireless network to the system controller. Each stimulant target unit has a light source providing light to stimulate a user, a proximity sensor providing an output of a distance between the proximity sensor and an object external to the unit, and means for providing feedback to the user to signal that the unit has been actuated by the user. The system controller includes a program for activating the stimulant target units in a sequence. The reaction by the user to the illumination is registered when the user brings a body part or other object to within a selected distance of the proximity sensor, this distance being programmable by the user.

A volleyball statistic keeping user interface provides rapid identification of players and volleyball actions without needing to display pre-set buttons for every player currently on the court. In some embodiments, a virtual court representing a volleyball court is generated. A state machine determines the most likely volleyball action to occur at any point in the virtual court during gameplay. Thus, when a user selects a location in the virtual court, the state machine automatically triggers a highest probable action for the location which may be confirmed by the user and the statistic is automatically logged into the record. The entire process may occur in split seconds allowing the user intuitive touch and record keeping alongside the pace of real-time volleyball play.

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

Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a server processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the server processor with time stamps. The server processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

A sports ball may include a bladder having one or more inserts attached to or imbedded therein. The inserts may include a battery, a charging element, one or more microprocessors/sensors, memory and/or a speaker. The bladder may include pockets formed into the bladder either extending from the outside into the bladder and/or pockets disposed on the inside of the bladder. A hub for communicating with several balls and/or display devices may also be included.

A system for coordinating radar data and image data to track a flight of a projectile includes a radar, an imager, and a controller. The imager provides an image of an area into which a projectile is to be launched. The controller receives the image and an identification of a target within the image and identifies a target line connecting the target and a launch position of the projectile. The controller also receives data from the radar relative to at least a portion of a trajectory of the projectile, generates image based trajectory data by correlating the radar data and the image, and alters the image to include the image based trajectory data within the image and the target line within the image.
