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.

The present disclosure relates to systems and methods for balance index determination. For example, a wearable apparatus may have at least one gyroscope configured to measure angular velocity about a first axis; at least one inertial measurement device (IMU) configured to measure deviation along a second axis and a third axis; at least one memory storing instructions; and at least one processor configured to execute the instructions to: receive angular velocity measurements over a period of time from the at least one gyroscope; receive deviations from the second axis and from the third axis over the period of time from the at least one IMU; weight the deviations based on directions associated with the deviations; and generate a composite balance index based on the angular velocity measurements, the weighted deviations from the second axis, and the weighted deviations from the third axis.

A muscle activating and exercising device and a method of activating and exercising muscles of the human body. The device includes an outer material and at least one flexible inner material. The device is an elongated device that is pliable enough to be wrapped around an object. The device also has an outer surface that creates a frictional fit between the device and the wrapped object. The wrapped object could be, for example, a wrist or ankle on a human limb or a location on a portion of sports equipment (e.g., a lacrosse stick, baseball bat, hockey stick, golf club or tennis racket). The method includes a method of activating muscles using the device. Through such a method, a user can, for example. build muscle strength and/or reduce muscle tremors.

A wearable training apparatus has a vision-control assembly and a head-mounting assembly coupled to the vision-control assembly. The vision-control assembly has a see-through area corresponding to a central portion of the human field of vision (FOV), and a vision-blocking area for blocking the human peripheral FOV except the central portion thereof. The wearable training apparatus may be in the form of a pair of eyeglasses with lenses provided with reduced FOV or alternatively, may be in the form of a goggle with reduced FOV. A training system may comprise one or more wearable training apparatus, one or more imaging devices for recording images and/or video streams of the performance of users wearing the training apparatuses, and one or more computing devices for playing back and analyzing the recorded images and/or video streams.

The present invention pertains to a ball-striking aid apparatus or simulator that includes a chassis for holding a ball and allowing rotation thereof, one or more sensors for detecting one or more ball stroke parameters and optionally a computing device being in communication with the one or more sensors and adapted to provide an input with respect to the one or more parameters.

Disclosed is a combined digital scorekeeper and vibration dampener device. The device is encased in a housing fabricated from a vibration dampening and/or shock absorption material. The device includes a plurality of string channels for attaching directly to the strings of a racket, and provides a miniature scoreboard that is operated by a simple mechanical or touch button system, so as not to distract the player's from the game. In an embodiment, the device is includes wireless technology to exchange scores and other data with other digital scorekeeper devices used by other players during a game, or via a network to a remote device to document the statistics from the match or provide data for other applications or sharing with others. In an embodiment, the digital scorekeeper includes one or more inertial sensors configured to detect and/or measure various data associated with the player's performance, which can be synced to video and used with training applications.

In a first aspect, a method for monitoring a golf swing is provided that includes coupling a mobile telephone to a golf club and employing the mobile telephone coupled to the golf club to monitor acceleration of the mobile telephone as the mobile telephone swings while a user swings the golf club, collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings, analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information, and output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone. Numerous other aspects are provided.
