An accuracy ball has a target strike cover, sensors, grips, and a data core that function in combination to provide a device that a trainer can hold and a fighter can practice striking accurately. The accuracy ball has target aim points that a user attempts to strike. The ball can gather data concerning the user's performance during a workout, including strike: accuracy/precision, strength/force, number and velocity, etc. The target strike cover can provide cushioning, as needed. Internal grasp handles allow the accuracy ball to be held safely by providing protection from errant strikes. Sensors including force plates, accelerometers, gyroscopes, location sensing, temperature, pressure, humidity, etc. can all be incorporated. On/off switch, IO port (such as micro-USB), wireless communication devices, display screen, control switches, etc. can be integrated therein as well. Exported data can be tracked, analyzed, graphed, and used to enhance learning and improve skill-sets.

In one general aspect, an apparatus to monitor movement of an object may include an input device configured to trigger pre-selection of a type of performance of the object, at least one sensor used to measure a motion parameter of the object, a controller configured to receive the motion parameter of the object and compare the measured motion parameter with a motion reference, and an output device configured to display, in real-time, a feedback information based on the comparison.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

The present invention discloses an intelligent household air purification cabinet type body-building apparatus, comprising a box body, a running machine, an air purifier and a power supply.

The intermediate striking assembly includes a body having a target area and at least one sensor. The sport combat training machine further includes a top plate assembly having at least one sensor.

A method for identifying and correcting muscular and skeletal disbalances through exercise includes recording, by a processor, using at least one sensor coupled to the processor, an exercise motion performed by a user, identifying, by the processor, a motion deficiency of the user based on the detected exercise motion, formulating, by the processor, a corrective motion based on the detected motion deficiency, and providing, by the processor, the corrective motion to the user, which also includes identifying motion deficiencies as far as range of motion, balance, symmetry, smoothness, strength, stamina and other motion characteristics, formulating corrective exercise program that involves multiple training machines, formulating exercises in terms of number of repetitions, cadence (frequency) or motion, range of motion, added resistance levels, communicating the corrective exercise program via the screen embedded on each machine, and guiding the user through each exercise, directing user to change exercise machines.

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

In some aspects, the disclosure is directed to methods and systems for determining ballistics of golf balls in different atmospheric conditions. The system can receive a set of characteristics for a plurality of golf swings of a golf ball under baseline atmospheric condition. The system can generating a player profile comprising an average of each of the set of characteristics for the plurality of golf swings. The system can identify a second atmospheric conditions different from the baseline atmospheric conditions. The system can calculate a predicted distance traveled by the golf ball if hit by a golf swing under the second atmospheric conditions. The system can present, in a graphical user interface, the predicted distance traveled by the golf ball under the second atmospheric conditions.

An American style football including an inflatable bladder, a cover surrounding the bladder, a battery carried by the football, and a light emitter. The light emitter is carried by the football and is electrically connected to the battery. At least a portion of the cover transmits light from the light emitter.

Techniques for automatic tracking of user data for exercises are disclosed. In one aspect, a method of operating a wearable device may involve determining that a user of the wearable device has started an exercise, activating the GPS receiver in response to determining that the user has started the exercise, and detecting a time at which the GPS receiver achieves an initial GPS fix of a location of the wearable device. The method may further involve logging, based on output of the one or more biometric sensors, a first set of user data during a first time interval between the start of the exercise and the detected time of the initial GPS fix, and back-filling an exercise route of the user during the first time interval based on the first set of user data.
