A circuit breaker with at least one disconnect mechanism and a smart monitoring system implements nuanced fault logic in order to minimize disruption to operation of the circuit breaker under a fault condition, and enables the circuit breaker to address nuisance or low severity faults separately from load switching. Under low severity or nuisance fault conditions, the smart monitoring system temporarily disconnects affected loads from the power supply rather than tripping the entire circuit breaker so that the loads can be reconnected to the power supply if the fault condition resolves within a short amount of time. In addition, the disconnect mechanism(s) that are used to temporarily disconnect the load(s) are configured to be re-closed after opening without requiring manual intervention. In high severity fault conditions, the smart monitoring system actuates tripping of the entire breaker, requiring manual re-closing of the circuit breaker.

One of the most important factors affecting the performance of athletes in club, bat or racket based sports is the athlete's swing or sporting action with their club, bat or racket. Minor changes in swing path and speed can have a significant impact on the outcome of a shot or other sporting action. As there are many factors affecting shot outcomes and small changes in the athlete's swing can have a large impact on the shot outcome, it is difficult for inexperienced athletes and coaches to correctly diagnose and fix grip faults. The present disclosure provides a tool movement analysis system 10 comprising a tool sensor positionable on a tool, a body sensor positionable on a user, and a processor configured and operable to collect and analyse data related to the user's movement with the tool and provide relevant feedback to the user.
