摘要： A system for a sports activity, which system is adapted to detect potential game contacts that include contacts between games equipment (1) and a games object (2) and/or contacts between a games object (2) and a target surface (5), and the system comprises sensor means (3a, 3b) adapted to detect vibrations caused by potential game contacts and to convert these vibrations into sensor signals. The system is adapted to define the value of the sensor signal at several consecutive discrete time instants, define for a sensor signal section within a time frame k that contains N sensor signal values an energy value quantity E[k] that is related to the energy of the sensor signal section, repeat the above step of defining the energy value quantity of the sensor signal section for several consecutive time frames, and detect a potential game contact by utilizing a detection function D that is obtained by a linear combination of energy value quantities of sensor signal sections contained in consecutive time frames by using the formula D  [ k ] = ∑ i = 0 K - 1   c i  E  [ k - i ] , wherein K is the number of energy value quantities used in calculation and an integer equal to or greater than two, and ci is a weighting coefficient for the energy value quantity E[k−i], whereby the detection of a potential game contact in the time frame k is based on comparing the value D[k] of the detection function D corresponding to the time frame k is compared with a threshold value.
