Abstract:
Apparatus (1) comprises a standing surface (2) for the player; a communication means (27); and a plurality of sensors (11) which are operable to measure force. The standing surface (2) comprises two separate foot platforms (3, 4) for the player's feet. Each foot platform (3, 4) comprises a supporting structure or supporting members where vertical forces are distributed to a plurality of discrete positions (5). The sensors (11) are located at the discrete positions (5) to which the vertical forces are distributed. The sensors (11) are operable to measure vertical forces. The apparatus also comprises a computing means (26) which is operable to analyse the swing, and includes means to receive and separately process signals from individual or groups of sensors (11); means to determine the relative magnitudes and positions of resultant forces by balance-resolution of forces, including individual forces, measured by the sensors (11) in relation to the discrete positions of the sensors (11); and means to analyse and evaluate numerical data related to the measured positions and magnitudes of the forces.
Abstract:
The system automatically or partly automatically coaches and assesses a non-putting golf swing to increase the strength or distance of the swing. Increases are coached in the components of energy generated across specific individual joints of the player's body during the downswing. Increases are also coached in the efficiency at which the generated energy is transmitted to the clubhead. Fast or near-instantaneous feedback is provided to the player, based on measured changes in the components of energy generated in the specific individual joints and on the efficiency at which the generated energy is transmitted to the clubhead. Changes in 3D positions of the player's body segments or joints are tracked by inertial sensors or optical sensors and used in the calculation of the components of energy generated across the specific individual joints utilising an artificial intelligence system.
Abstract:
A system or apparatus (1) determines movement characteristics of a golf club (19) and ball (13), including spin characteristics of the ball, without addition or detection of marks or markers on the ball. A beam interrupt system measures club movement up to and including impact and ball movement at and following impact. Spin characteristics are determined, including spin components and causes of spin.
Abstract:
A method of an apparatus for measuring or determining the movement characteristics of an object uses the detection of changes in beams. A set of beams F1-B1, F2-B2, F3-B3 is disposed in the movement path of the object; at relative angles to each other; and at acute angles to the intended direction of the object. The number of changes in the beams or durations between changes in the beams are recorded. The relative times, durations or differences in relative times, at which different beams of the set are changed are measured. The resulting measurements are associated with the relevant movement characteristics of the object.

Abstract:
An apparatus for adding an additive, such as a marker, to a base fluid, such as oil, includes a blender having a receptacle or diffusion chamber in which mixing of the additive and the base fluid occurs. The additive is injected in discrete amounts. Resistances to fluid flow in the receptacle or chamber cause fluid flow to occur at different rates in order to reduce the slugging effect caused by additive injection in discrete amounts.
