Abstract: Apparatus and methods for expandable storage and metering are disclosed. In some embodiments, the expandable storage and metering device comprises a body with a storage cavity therein, a chassis upon which the body is mounted, and at least one port in communication with the storage cavity, wherein the body is expandable and collapsible to change the internal volume of the storage cavity. Some method embodiments for operating the expandable storage and metering device comprise expanding the device and collapsing the device, wherein said expanding and said collapsing comprises utilizing actuators to raise/lower or extend/retract the walls of the device. In other method embodiments for operating the device, said expanding comprises removing the roof of the device and positioning at least one stackable module on top of the device and said collapsing comprises removing the at least one stackable module and replacing the roof.

Abstract: An equalizer receives an analog input signal and filters the signal to undistort the input signal. A converter stage converts the analog input signal into a digital output signal for use in a digital system. A bit sequence indicator analyzes the structure of the digital output signal to determine whether any errors have occurred in transmission and conversion. An adaptor state machine causes the modification of the analog signal based on a feedback loop including information on the errors detected in the packets of digital signals, rather than the analog data itself.
