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.

Various embodiments of a golf club senor housing are described herein. The sensor housing can include a cover and a base that enclose a sensor therebetween. The sensor housing can be designed to sit on the end of a grip in a position that is non-obtrusive to the user. The sensor housing can further be configured to minimizes the impact on the center of gravity (CG) of the golf club by including mass reducing features. The sensor housing is also configured to sit lower on the grip and reduce the length that it projects outward from the grip butt end. Reducing the added length from the sensor housing creates a less-obtrusive feature.

An impact label for use as a baseball training aid includes a deformable layer and an incompressible layer which may include aluminum foil and paper, respectively. The incompressible layer includes voids distributed in a regular pattern. A first side of the incompressible layer is adhered to the deformable layer. A second side of the incompressible layer is formed around the barrel of a baseball bat, e.g., via an adhesive on a base layer. Areas of the deformable layer proximate to the voids and within an area of contact with a baseball during a swing of the bat are adapted to deform in response to contact with the baseball, thereby creating dimples that are indicative of the area of contact and force of contact.

A racket dampener swing sensor apparatus to obtain measurements of parameters relative to the player's performance while reducing vibration includes a dampener body having a body front side, a body back side, and a body perimeter. The body perimeter has a string channel to selectively engage a plurality of strings of a tennis racket. The dampener body absorbs vibration from the plurality of strings. An accelerometer and a microcontroller with memory are coupled within the dampener body to measure hit velocity for each shot type (forehand, backhand, serve, topspin, slice, or flat). A vibration sensor is provided to detect when a ball is struck. A transceiver is coupled within the dampener body to wirelessly communicate with an app on a smartphone or computer. A battery is coupled within the dampener body and a charge port is in operational communication with the battery.
