Abstract:
1. Device to use in sports and games for detecting the position of impact of a moveable object, comprising: a sheet or mat with an outer layer and an inner layer, the sheet or mat forming a target surface; a plurality of electrically conductive elements embedded in the sheet or mat and forming pressure sensitive switches distributed over the target surface and communicating with electronic circuits for outputting, processing and displaying electrical signals from pressure sensitive switches when activated by said impact or pressure, wherein the plurality of electrically conductive elements comprise a first pattern of electrically conductive elements provided at an underneath side of the outer layer of the sheet or mat at least at the positions of the pressure sensitive switches, and a second pattern of electrically conductive elements provided at an upper side of the inner layer of said sheet or mat at least at the positions of the pressure sensitive switches, the first pattern of electrically conductive elements and the second pattern of electrically conductive elements being arranged so as to enable temporary contact to be established at the positions of the pressure sensitive switches, and an insulation layer between said outer and inner layers is provided with cavities or holes at the positions of the pressure sensitive switches for establishing temporary contact therein, and from each cavity or hole at least one opening directed sideways for air movement during said impact or pressure activation, and wherein at least one of the first and second patterns of electrically conductive elements is subdivided into a number of individual zones, where each zone comprises a plurality of said pressure sensitive switches, and the electronic circuits have separate connections to each of said individual zones.
