摘要
An American style football including an inflatable bladder, a cover surrounding the bladder, and an electronic circuit. The bladder includes first and second side walls defining an expandable cavity and a cross-member configured to extend through the expandable cavity. The side walls and cross-member are coupled together to form a bladder seam. The electronic circuit is coupled to the cross-member and produces a signal to enable the position and movement of the football to be monitored during use.
