Abstract: A method to be carried out at an electronic device for detecting proximity to another electronic device is described. The electronic devices are capable of interaction through both low-accuracy sensing and high accuracy sensing. Low-accuracy sensing is used until a potential proximity event is detected. High-accuracy sensing is then activated, and attempts are made using high-accuracy sensing to detect a further potential proximity event corresponding to the potential proximity event. A determination is then made as to whether a proximity event has taken place—this is done using the further potential proximity event if detected, and using the potential proximity event otherwise. A suitable electronic device is also described, as is a method of training electronic devices to detect proximity to other electronic devices using a proximity estimation algorithm.

Abstract: 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.

Minor changes in grip position and force can have a significant on the outcome of a shot or other sporting action. Typically, athletes receive feedback on their grip, and the resulting shot, through coaching or practice. However, it is difficult for inexperienced athletes and coaches to correctly diagnose and fix grip faults. The present invention provides a grip analysis system, and method of use thereof, including an array of pressure sensors configured to detect a grip of a user on an object and a processor operable to analyse data from the array of pressure sensors and output at least one grip quality indicator corresponding to the grip of the user on the object.

Abstract: Electronic training and feedback devices have been developed to provide accurate and impartial data or feedback to athletes of club, bat or racket based sports. However, the due to the requirements for these devices to be small and lightweight, their integral power sources typically have a small capacity and therefore require charging often. To charge these devices, the athlete must typically connect the device or their sports equipment to a mains power source after they have finished playing or practicing. However, the athlete may forget to charge their device, and the device may not hold enough charge to last the athlete's next session. Therefore, it is desirable to provide a charging system capable of simply and conveniently charging smart sports equipment.
