Some disclosed golf club heads include body having at least one raised sole portion and a cantilevered ledge extending down around a perimeter of the club head below the level of the raised sole portion. Some disclosed golf club heads include one or more sole openings in the body and a sole insert that is mounted inside the body over the sole openings. The sole can include weight tracks as well, and a rear weight track can extend between a toe side sole opening and a heel side sole opening. A crown insert can also be included that is mounted over an upper opening in the body.

Articles of sports equipment, such as striking implements (e.g., sticks) and wearable articles (e.g., skates, helmets) for playing hockey or other activities, in which at least one of the characteristics (e.g., stiffness) of the articles of sports equipment is adaptable and can be altered during use of the sports equipment, such as by comprising an alterable component coupled to a controller, by comprising an alterable component that is autonomously alterable, and/or by an alterable component that can be altered in response to a command of a remote device.

A golf swing training apparatus has a shaft, a housing with a top cap and a bottom cap, and a plurality of weighted discs receivable within the housing. A golfer may adjust the weight of the head of the club by adding or removing weighted discs in the housing. The golf swing training apparatus may comprise an accelerometer within the housing so as to measure the speed, acceleration, and swing path that the club takes for feedback and analysis to improve the golfer's swing.

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

A method of predicting the likelihood of a post T-off golf swing or consecutive swings resulting in a ball being sunk in a hole; the method utilizing communication equipped cameras or communication equipped laser rangefinders at known locations to determine accurate ball lie information. Transmission of this location information in real time to a processing facility linked to a database of historical play information incorporating at least ball position information and golf course in order to calculate odds of success of the upcoming swing and/or subsequent swings.

A system including a computing device and camera is disclosed; the system configured for measuring three-dimensional attributes and associated performance measurements of a mechanical device. Some embodiments comprise a camera configured to capture images of the mechanical device and a computing device in communication with the camera. In some embodiments, the computing device is configured to access a first set of pixels associated with a first plurality of fiducials to calibrate a spatial resolution of the camera. A second image from the camera can be converted into a second set of pixels associated with each of the plurality of fiducials, which are attached to the mechanical device. The computing device can be further configured to compare the first and second set of pixels to determine the location of the plurality of fiducials on the mechanical device.
