A method of manufacturing a seamless inflatable ball contains: 1) inflating air into a preformed body so as to form a spherical body and covering a medium layer on the spherical body so as to form a semi-finished part; 2) forming a fluidic surface material on the medium layer of the semi-finished part in a predetermined thickness so as to produce a spherical portion with a covering layer; 3) placing the spherical portion into two ball molds; and 4) partially discharging air out of the spherical body and inflating the air into the spherical body repeatedly. In the step 3), the spherical portion is clamped in the two ball molds, and after the fluidic surface material is dried or is solidified to form a solid layer on the spherical portion, the spherical portion is removed from the two ball molds, thus forming a sphere.

A football device includes an outer skin and an inner bladder to be inflatable and substantially resemble and perform like an actual football. The football device includes a sensor unit that can sense various performance metrics and wirelessly communicate data to another device such as a mobile device. To maintain a feel and performance as close to an actual football as possible, a battery powering the sensor unit is wirelessly recharged.

A throwing apparatus and method a throwing apparatus has a main body connected to a base. A cocking arm is connected with the main body at a main body axle and movably connected with a release arm. A throwing assembly is connected to a throwing assembly bracket connected to the main body at the main body axle, where the throwing assembly includes an adjustable angle assembly movably connectable with the throwing assembly, the throwing assembly configured to support a projectile, where the projectile is held at selected angles in relation to the throwing assembly by the adjustable angle assembly and where the release arm is configured to releasably connect with the throwing assembly. A power assembly is provided with a first end and a second end, where the first end is connected with the throwing assembly bracket and the second end is connected with the main body.

Systems and methods for sensing and monitoring various athletic performance metrics, e.g., during the course of a game, a practice, a training session, training drills, and the like, are described. These systems and methods can provide useful metrics for players and coaches relating to athletic performances in various sports, including various team sports.

A goal shooting target can be used to develop skills in many sports. The goal shooting target can include a panel that deflects objects when the panel is placed at a face or opening of a sports goal. The panel and sports goal can define target openings through which objects are capable of passing. The panel can be configured to carry a frame of the sports goal such that posts of the sports goal are held off of a support surface upon which the goal shooting target rests.

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

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 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 processor with time stamps. The 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 luminous leather for a sports ball includes a base fabric, a polyurethane (PU) layer, a luminous layer and a film. The base fabric, the PU layer, the luminous layer and the film are sequentially bonded by glue from bottom to top. The luminous layer is a fluorescent coating. The luminous leather for the sports ball has an enhanced luminous effect while being wear-resistant. In the new luminous leather, the luminous layer is added, and the luminous layer is a fluorescent coating. In this way, sports balls made of the new luminous leather come in different surface colors to be more entertaining. Meanwhile, a film is immediately coated onto the luminous layer by a roller before the glue gets dry to enhance the luminous effect and the color brightness, while making the entire leather more wear-resistant.

Systems and methods are described for generating a three-dimensional track a ball in a gaming environment from a single camera. In some examples, an input video including frames of a ball moving in a gaming environment recorded by a camera may be obtained, along with a camera projection matrix associated with at least one frame that maps a two-dimensional pixel space representation to a three-dimensional representation of the gaming environment. Candidate two-dimensional image locations of the ball across the plurality of frames may be identified using a neural network or a computer vision algorithm. An optimization algorithm may be performed that uses a 3D ball physics model, the camera projection matrix and a subset of the candidate two-dimensional image locations of the ball to generate a three-dimensional track of the ball in the gaming environment. The three-dimensional track of the ball may then be provided to a user device.
