An elastic thermoplastic diaphragm for use in a vessel having an inner surface. According to the disclosed techniques, a local video communication device transmits PIP information to a remote video communication device. The ullage cooling assembly includes a turbine coupled in flow communication downstream of the heat exchanger, wherein the turbine is configured to further reduce the temperature of the ullage gas and facilitate channeling the ullage gas to the fuel tank. The pick-and-place module can be applied to all customer trays having different loading capabilities when only the kit of the pick-and-place module needs to be replaced, so there is no need to manufacture the entire pick-and-place module and this reduces manufacturing costs. The channels can be ranked in the priority database based on their priority in relation to one another.
