Systems and methods for identifying golf equipment. The system may include one or more performance tracking devices, such as an optical sensor system or a radar sensor system for tracking at least one of a golf club swing or a golf ball flight. The system also may include at least one processor and memory storing instructions that, when executed by the at least one processor, cause the system to perform a set of operations. The operations include receiving current dynamic input for a golf shot from a golfer and current static input for the golfer. The operations also include executing a trained machine-learning model based on the received current dynamic input and current static input to generate predicted golf club properties and/or predicted golf ball properties for the golfer. The predicted golf club properties and/or predicted golf ball properties are displayed on a connected display.

Provided is a sensor device-equipped golf shoes comprising: golf shoes including a left and right pair of a first shoe and a second shoe to be worn by a golfer; and a sensor device attached to the golf shoes. The sensor device includes one or more sensor modules configured to measure sensor data pertaining to at least one of an orientation of the first shoe when the golfer takes a shot, an orientation of the second shoe when the golfer takes a shot, and a positional relationship between the first shoe and the second shoe when the golfer takes a shot.

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.

A method for unlocking a control unit of an exercise machine includes providing the exercise machine, having at least one sensor for detecting presence of a user on the exercise machine, with at least one electrical signal representative of a detection carried out at the time of the occupation of the exercise machine by a user. The method further includes switching, by the exercise machine, the control unit of the exercise machine from a first locking condition to at least a second operating condition in which the user may issue commands to the exercise machine by the control unit, based on the at least one electrical signal provided by said at least one sensor for detecting the presence of the user on the exercise machine.

Golf balls including a plurality of radar detectable marks disposed on any single layer or among two or more layers thereof are provided. When all of the radar detectable marks present on any layer of the ball are radially projected onto the outer surface of the ball, the resulting overall pattern of projected radar detectable marks includes a series of three or marks located on a 1.5 mm wide great circle band on the outer surface of the ball.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

A method includes identifying a first point on an object striking element in a first image and a second image from images. The first and second images are captured within a predetermined time span of an impact of the object with the element and determining an impact time of the impact in combination with determining a position in the first and/or second images corresponding to a location of the object at the impact time. Based on the positions of the first point in the first and second images, determining a position in the first and/or second images corresponding to a position of the first point at the impact time. The method also includes determining a distance from the imager to a location at which the object and the element impact one another and determining an impact location of the object relative to the first point.

An exercise machine comprises a motor. The exercise machine comprises a lockable translatable mount. The exercise machine comprises a cable coupled to the motor via the lockable translatable mount. The exercise machine comprises a sensor coupled to the lockable translatable mount. The sensor is used at least in part to determine mount lock state.

A system for measuring golf ball trajectory characteristics is disclosed. The system includes artificial grass with a launch location for a golf ball and a plurality of wide-angle distance optical sensors mechanically connected to the artificial grass positioned such that a field of measurement of each wide-angle distance optical sensors intersects. The system also includes a central processing unit connected to the wide-angle distance optical sensors, the central processing unit configured to collect distance measurements from the wide-angle distance optical sensors and to determine a velocity of a trajectory of the golf ball from the launch location to the intersection of the field of measurement of each wide-angle distance optical sensors given a distance between the plurality of the wide-angle distance optical sensors, a distance between the plurality of the wide-angle distance optical sensors and the launch location, and the distance measurements from the plurality of the wide-angle distance optical sensors. Once the velocity of the trajectory of the golf ball is determined, the central processing unit transmits the velocity to a display.
