Abstract: A resident application (RA) in set-top terminals (STTs) is updated by providing an upgrade channel application (UCA) over a network. Those STTs that are selected to receive the UCA are identified. The selected STTs download the UCA from the network. Once the UCA begins to execute on an STT, it retrieves the user parameters stored in the STT, and transmits them to a remote location for storage. A new RA is then installed in the STT. The original user parameters are converted at the remote location to become compatible with the new RA. The converted user parameters are transferred to the STT for use by the new RA.

Abstract: A method of gas tank ullage indication is designed to be made up of a coating or film attached to the surface of a tank for holding compressed gas. This is used normally when the tank is warm as is the case right after the tank is pressured with gas. The coating includes materials which change in appearance when various specific temperatures are reached. The changed appearance allows indications to be seen that tell the observer how the pressure will change after the tank has equilibrated to some specific temperature.

Abstract: An ullage meter is designed to be made up of a coating or film attached to the surface of a tank for holding compressed gas. This is used normally when the tank is warm as is the case right after the tank is pressured with gas. The coating includes materials which change in appearance when various specific temperatures are reached. The changed appearance allows numbers to be seen which tell the observer how much pressure will be lost after the warm tank has cooled to some specific temperature. This loss is an ullage.
