Abstract: A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.

Abstract: A rocking chair mechanism (I) comprising a rotating rocker (2), a stationary support (3), a springing means (4), an upper assembly (5), and a lower assembly (6), such that rotating (rocker 2) and springing means (4) are laterally integrated. Rocking chair mechanism (1) is an independent unit that can be manufactured separately then supplied to rocking chair manufacturers for incorporation into rocking chairs such as rocking chair (7). Alternatively, a rocking chair such as rocking chair (7) can be constructed using a laterally integrated rocking chair mechanism within each arm.
