Embodiments of the invention include systems and methods for selective gripping andor releasing of media cartridges using a robotic ratcheting gripper mechanism. The receiver can then re-transmit the meter data through a wide area network such as the Internet to a web site operated by an organization marketing AMR systems. The adjustable torque is set to a minimum when the weight is in the working position in order to lower the band saw toward the workbench. A rectangular gasket is disposed on the second side of the filter flange assembly and circumscribes the central aperture.
