Abstract: A member naming system is provided for naming members of a dimension in a data analyzing system having a receiver for receiving a pattern. One example of the dimension is a time dimension containing time periods. The pattern has a sequence of pattern components for defining a name. A time period is defined by a start time, an end time, a relationship and a level in a single time hierarchy. The time period naming system further has an interpreter for interpreting the sequence of pattern components, and a generator for generating the time period name based on the interpretation of the sequence of pattern components within a context of the relationship of the time period in the time hierarchy.

Abstract: An improved airship that is uniquely constructed so as to be inexpensive yet easy to pilot and highly maneuverable includes an outer skin that defines a nose portion and a tail portion of the airship and an internal envelope. At least one gas bag is contained within the envelope. A gondola is secured to and positioned beneath the outer skin. Most advantageously, a propulsion mechanism is positioned proximate to the tail portion and is constructed and arranged to create propulsive thrust that is vectored so as to be substantially colinear with a centerline of the airship that extends through the nose portion and the tail portion of the airship. The airship also may include a ballonet-free internal pressurizing system that introduces outside air into a location between the outer skin and the gas bag when pressure at that location has reached a predetermined minimum pressure. As a result, the envelope is sufficiently pressurized to maintain its outer shape without use of a ballonet.
