Abstract: A sports object comprises an electronic circuit having a power source and a transmitter and arranged to transmit a signal identifying the sports object. The sports object has an inner core encapsulating the electronic circuit. The inner core is configured such that the inner core and electronic circuit are balanced. There is at least one outer core layer encapsulating the inner core. The sports object is used in a system for providing sports game information. The system comprises the sports object and a portable computing device including a receiver responsive to the signal and a location means for determining the location of the computing device. The computing device records the signal received at two or more different locations and records the location of the computing device at each of the different locations to enable estimation of a location for the sports object identified by the received signal.
