This disclosure relates to using a hand held target (e.g. tae kwon do paddle) as a tool for providing physical performance instructions according to a digital workout performance template loaded in advance.

A method, including scanning a golf club to obtain scanning information; inputting the scanning information into a processing system; using at least one camera positioned behind and in-line to a golf swing direction and at least one lighting unit to obtain a series of images of a golf club during the golf swing; converting the series of images into parameterized motion representations; using at least one radar to obtain a radar signal; inputting the parameterized motion representations and the radar signal into the processing system; receiving golf club parameters and golf swing parameters as an output of the processing system; and generating a visual model of the golf club and the golf swing in a virtual space using the golf club parameters and the golf swing parameters.

A handheld exercise device is an apparatus that enables the user to exercise the upper body due to the load applied on the user's arms from the centripetal force created by moving the apparatus using one or two hands. To do so, the apparatus may include an O-ring housing, a crossbar, a bearing assembly, and a control system. The O-ring housing is designed to retain the bearing assembly in such a way that the user can move the bearing assembly in a circular motion within the O-ring housing. The crossbar facilitates the handling of the O-ring housing with one or two hands in order for the user to move the bearing assembly in a circular motion within the O-ring housing. The control system helps the user keep track of the movement of the bearing assembly so that the user can measure the exercise progress while handling the apparatus.

The present invention provides system and method for tracking and analyzing golf shot, the method comprising: turning on a light source; a capturing a pair of images of the golf shot using a pair of stereo cameras having a same focal length and triggered by single signal; a analyzing a disparity between the pair of images; a producing a disparity map, a three dimension simulation, and a first motion analysis data; a capturing an image of the golf shot from before to after contact between a golf club and a golf ball using a single camera; a analyzing image sequences captured by the single camera; a producing a second motion analysis data including at least one of ball spinning, club face angle, and swing, and displaying the three dimension simulation, the image sequence, and the first and the second motion analysis data.

The present disclosure is directed to climbing wall assemblies having a variety of improvements. For instance, the climbing wall assemblies may include connectors to attach the surface panels to the framework, in which the connectors may be mounted substantially anywhere along the front of the framework and at substantially any angle, providing for the securement of climbing panels in various geometries. The climbing wall assemblies may also include braces that may easily be adjusted to a desired length and configuration during construction of a climbing wall. The climbing wall assemblies may also include variable-angle, integral front posts, which provide for the easy and stable securement of climbing panels in various geometries. These improvements provide climbing wall assemblies that may be easily assembled to produce a desirable climbing wall structure having few framework components.

A handheld underwater aircraft includes a battery compartment (12) and propellers. There are at least two propellers, which are symmetrically distributed on both sides of the battery compartment (12), and are connected to the battery compartment (12). A special design with axes of the propellers being unparallel with an axis of the battery compartment (12) is adopted, and unparallel included angles make component forces generated by the various propellers in a direction of motion of a non-underwater aircraft offset each other, and enable the underwater aircraft to maintain balanced and forward-forward motion. The design with the axes of the propellers being unparallel with the axis of the battery compartment (12) leads to a little power loss, but avoids a larger power loss caused by the impact of water on the human body, thereby comprehensively improving the thrust of the underwater aircraft in use.

Embodiments of the present invention are directed to an adjustable-incline climbing wall. The climbing wall includes one or more climbing panels supported by a frame and a system for adjusting the incline of the frame to provide a climbing wall of a desired incline. The incline of the climbing wall may be adjusted by activating an actuator, which extends the frame a distance from a support wall, tilting the climbing wall to a desired incline. Further, by providing a plurality of attachment points between the actuator and the frame (and/or between the actuator and a support), the adjustable-incline climbing wall may be provided with a wider range of incline angles, as well as increased control over those angles.

A putting training device and method for monitoring and tracking a golfer's putting activities.

A device for generating virtual golf holes on a green includes a housing configured for coupling to a golf pin at a distance above a green, one or more cameras located within the housing, the one or more cameras configured to gather data from an area of the green surrounding the golf pin, one or more speakers located within the housing and a processor located within the housing and communicably connected with the one or more cameras and the one or more speakers, the processor configured for generating an internal representation of one or more virtual golf holes around the golf pin, reading the data from the one or more cameras, determining whether a golf ball detected by the one or more cameras has entered the one or more virtual golf holes, and activating the one or more speakers to play one or more audible sounds if the golf ball detected by the one or more cameras is determined to have entered the one or more virtual golf holes.

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