Abstract: A device for detection of tampering with the interior of sports implements or other hollow opaque objects. The device is inserted in the interior of the object and includes an RFID tag with supporting microcircuitry for transmission of a signal. The signal can be detected outside of the device. Persistence of the signal indicates that the body of the object has not been breached or otherwise adulterated. The microcircuitry includes a kill switch that terminates the signal when the interior of the object has been compromised. Inability to detect a signal indicates tampering of the object. The device enables quick and easy screening of objects for compliance with rules or performance standards.

Abstract: A rubber or synthetic texture sleeve that fits loosely over the existing grip. It is made from typical grip material for the application with the exception of having a smooth or textured interior and being oversized for the handle. The sleeve may be used with an interior liner between the handle and the grip for additional cushioning. The length of the sleeve will vary, but can be cut to fit the specific application. The sleeve fits loosely around the bat grip and does not replace or modify the existing grip or bat handle. The degree of twist is determined by the give in the material used allowing for a stronger grip because the friction normally generated from rotating hands around a stationary grip is reduced dramatically. The sleeve reduces vibration because of the increased padding and ability to have a stronger grip.
