American-style football including electronics
An American style football including an inflatable prolate spheroidal shaped bladder, a cover assembly, a lacing and an electronic circuit. The bladder includes a valve assembly and a pocket that are symmetrically spaced about a longitudinal plane. The cover assembly includes at least first, second, third and fourth cover panels collectively positioned over the bladder. One of the first and fourth cover panels extending over the valve assembly and the other of the first and fourth cover panels extending over the pocket. The lacing extends along the longitudinal plane and coupled to the first and fourth cover panels. The electronic circuit is retained by the pocket. The electronic circuit includes at least one sensor and the electronic circuit being configured to produce a signal to enable at least one characteristic of the football to be monitored during use.
1. An American-style football comprising:
an inflatable prolate spheroidal shaped bladder including a valve assembly and a pocket, the valve assembly and the pocket being positioned symmetrically about a longitudinal plane;
