Abstract
A drum has a body, a lid, and fastening structure cooperable with portions of the body and lid to effect a releasable coupling therebetween. A sensor is disposed between the two portions. According to a different aspect, a support member has a flange with a hole, and a pressure sensor on the flange. A tag on the support member has circuitry responsive to the sensor for transmitting wireless signals. According to yet another aspect, a drum has a body, a lid, and fastening structure to effect a releasable coupling between the lid and the body. A method involves monitoring with a pressure sensor a force produced by the fastening structure.
