The invention relates to an inflatable ball bladder with two dual function valves (3) and a wired rechargeable electronic component (5). It provides an elastic cable (1) anchor mechanism to encapsulate an electronic device at the center of the bladder. The bladder includes an electrical connection in communication with the electronic device for charging the device as well as for exchanging data. The electronic device (5) comprises a sensor to sense speed, location, acceleration, and trajectory of the ball.
摘要:
An article includes a cushioning assembly which has a first bladder element forming a first fluid chamber, and a second bladder element within the first bladder element and forming a second fluid chamber sealed from and within the first fluid chamber. The first bladder element includes an inner surface having a first feature. The second bladder element includes an outer surface having a second feature. The first feature interfits with the second feature such that a first area of the inner surface of the first bladder element is aligned with a first area of the outer surface of the second bladder element at a bonded interface. The second bladder element is exposed to the first fluid chamber away from the bonded interface. A method of manufacturing the article includes interfitting the first feature with the second feature and bonding at the bonded interface.
