Techniques are provided for implementing a system for determining the range to a target object and orienting a map. In implementations, GPS data is used to determine the location of the system and an approximate distance from that location to the target. Based on the approximate distance, one or more parameters of operation of the system may be set. Modes of operation may be entered to further adjust parameters of operation. An optical pulse may then be projected at the target and its reflections collected and analyzed to calculate a distance measurement. A visual display may be adjusted based on the calculated distance estimate to the target.

This disclosure relates to systems, media, and methods for quantifying and monitoring exercise parameters and/or motion parameters, including performing data acquisition, analysis, and providing scientifically valid, clinically relevant, and/or actionable diagnostic feedback. Embodiments may be related to systems, devices, methods, and computer-readable media for providing baseline-adjusted real-time feedback to a user. Embodiments may include determining a type of activity for the user. Embodiment may include receiving data from the one or more motion sensors indicating a time-dependent series of three axis acceleration data and three-axis orientation data. Embodiments additionally may include providing a graphical user interface with a real-time representation of the received data. The real-time representation may include a scaled representation of at least one dimension of the time-dependent series of three axis acceleration data and three-axis orientation data for at least one of the one or more motion sensors based on the updated baseline adjustment.

The present disclosure relates to systems and methods for elastic delivery, processing, and storage for wearable devices based on system resources. For example, a wearable apparatus may have at least one battery; at least one sensor configured to measure at least one property associated with a user of the wearable apparatus; at least one memory storing measurements from the at least one sensor and instructions; at least one transmitter configured to send data to a device remote from the wearable apparatus; and at least one processor configured to execute the instructions to: receive, from the at least one battery, an indicator of a charge; and based on the received indicator, sending a command to the at least one sensor to operate in a low-power mode or a high-power mode, the low-power mode having. a lower sampling rate than the high-power mode.

A golf club head includes a body defining an exterior surface having a forward-most point and a rearward-most point that define a horizontal club head length therebetween that extends parallel to a ground plane. The body includes a face, a sole, and a crown. A front weight assembly having a first weight is secured with at least one fastener and defines a first center of gravity, and a rear weight assembly having a second weight is coupled with the body and defines a second center of gravity. A sole gap formed between an underside of the first weight and the sole defines a height of between 0.5 millimeters and 6 millimeters, the first center of gravity and the second center of gravity define a horizontal weight system length, and a ratio between the horizontal weight system length and the horizontal club head length is between 80% and 99%.

A golf club head formed of an alloy of steel that is capable of improving the center of gravity (CG) location while maintaining traditional external dimensions of the golf club head. More specifically, the golf club head in accordance with the present invention achieves a relatively low CG while maintaining traditional external dimensions by reducing the amount of mass contributed by the crown, the striking face, and the hosel, and strategically reallocating this mass within and/or proximate the sole of the golf club head.

Embodiments of portable electronic device holders and methods of manufacture of portable electronic device holders are generally described herein. Other embodiments may be described and claimed.

A training bat assembly for improving a user's swing of a baseball bat is provided. In one embodiment, the assembly includes a bat portion and a plug or cap portion, where the plug or cap portion is configured to mate with a distal end of the bat portion. For example, the bat may include a circular opening, and the plug may include a circular rod that is configured to fit within the opening. Alternatively, a cap with a circular opening can be used, where the cap is configured to fit over a distal end of the bat. By mating the plug or cap with the bat, and swinging the bat from a first position to a second position, the plug or cap is propelled from the bat, where the resulting location of the plug or cap can be used to determine the correctness of the user's swing was.

A divot repair tool for fixing divots in the playing surface made while playing golf. The tool is attached to the grip of a golf club and used to replace and fix divots in the grass. The club allows the tool to be extended to the ground without bending over or squatting down, thus reducing sports related injuries. The divot repair tool includes removable prongs and blade that can be used to fix the divot holes using a levering motion or a rotational motion. The divot repair tool can include an automated motorized embodiment that can rotate the tool and the individual prongs to repair the divot holes. Both versions can press the divot material up against a flat surface of the tool to further flatten the playing surface.

Described herein are devices and systems relating to sports training equipment, for example, for baseball. These devices and systems can comprise a mat with markers identifying a plurality of positions on the mat. In some embodiments, the system can comprise removably attachable footpads to identify ideal foot positions for an athletic performance. In some embodiments, the footpads comprise one or more pressure sensors. The system can comprise one or more position sensors on a ball, and one or more position sensors removably attachable to a hand-held sports instrument. In some embodiments, the system can comprise a memory, communicatively coupled to a processor and a camera, with executable instructions to implement a set-up component, a user recognition component, a practice component, and instructional component, and a play component.

A method for estimating information on a golf swing is provided. The method includes the steps of: estimating a three-dimensional position of at least one joint of a user, when two or more two-dimensional photographed images of the user's golf swing taken from different directions are acquired, by deriving probability information on a two-dimensional position of the at least one joint of the user from each of the two or more two-dimensional photographed images using an artificial neural network model, and combining the derived probability information on the two-dimensional position of the at least one joint; and estimating information on the user's golf swing with reference to the estimated three-dimensional position of the at least one joint.
