Embodiments of the present invention are related to a football training tool with an angled head, a rectangular frustum body, a pair of upper lateral rails, a pair of bottom lateral rails and a bottom. The upper later rails, defined as arms, include foot angle guides. The football training tool may also include a top alignment notch on its head and a bottom alignment notch on its bottom.

Golf balls including one or more layers having at least one radar detectable mark disposed on the surface thereof are provided.

Golf balls including one or more layers having at least one radar detectable mark disposed on the surface thereof are provided.

Golf balls including one or more layers having at least one radar detectable mark disposed on the surface thereof are provided.

Golf balls including one or more layers having at least one radar detectable mark disposed on the surface thereof are provided.

A golf instruction method, apparatus and analytics platform for determining the state of a putted golf ball relative to a target using information about the golf ball and external variables and remotely displaying the same, comprising a base unit, a mobile device or terminal, and an associated computer program including an analytics engine for analyzing a user's performance. The computer program determines whether and how a putted golf ball has missed said target and then stores, aggregates and displays that information for a user. The analytics engine is operable to aggregate data, analyze data and then correlate a user's actual skill proficiency to ball performance.

An information processing system includes processing circuitry that is configured to receive input data from a shock sensor which outputs data based on a shock on the shock sensor, and identify a target segment of time-series data that is output from a motion sensor that senses a motion of an object. The target segment includes a pre-shock portion that occurs before the shock event and a post-shock portion that occurs after the shock event, the shock event is recognized based on the data from the shock sensor.

A golf ball is disclosed herein that includes at least one radar detectable mark such that a projected pattern is formed when the at least one radar detectable mark is radially projected onto an outer surface of the golf ball. The projected pattern can have a first wave profile mapped along a path defined by a first spherical arc on the outer surface of the golf ball. The projected pattern can comprise at least one first crest and at least one first trough. The projected pattern can have a periodic function selected from: a sine wave, a sawtooth wave, a triangle wave, or a square wave.

The disclosure is directed to systems and methods for providing a user with key performance indicators of a basketball player relating to accuracy, precision and improvement. Specifically, the disclosure is directed to a system of sensors coupled to a basketball backboard adapted to provide an accurate tracking of a shot in a given three-dimensional space and extract features manipulated to yield key performance indicators based on establishing whether, how often and where the ball center passes the rim plane at a sub-cm resolution over a period of no more than 200 msec.

Systems for assisting a user with programming of a custom basketball shots made in a row practice arrangement includes a control system which receives data from a user interface indicating a user selection of a number of shots to be made in a row at each of a subset of pass receipt locations in the custom basketball shots made in a row practice arrangement and command a ball ejector to launch basketballs to a particular one of the pass receipt locations in the subset until data is received indicating that the number of shots is made in a row is made, and instead begin launching basketballs to a second particular one of the plurality of pass receipt locations in the subset. The control system also generates data for a report indicating performance feedback for the user during the custom basketball shots made in a row practice arrangement.
