Abstract: The present invention provides a method for prefabricating, transporting, and rapidly assembling a portable, rigid, dome-shaped structure, with the structural integrity to enable the suspension of extensive hardware and supplies. Said structure would be shaped for acoustic purposes, extremely durable, and allow for extensive climate control. Said structure would be able to be fabricated in a wide range of sizes and shipped to remote locations.

Abstract: The present invention relates to essential oils. In particular, some implementations of the present invention relate to systems and methods for diluting and diffusing one or more essential oils from a portable dispenser. In some cases, the described systems include a solution comprising one or more essential oils, emulsifiers, and diluents, wherein the solution is disposed in a container that is capable of diffusing the solution. While the various ingredients can be present at any suitable concentration, in some instances, a ratio between the volume of the essential oil and the volume of the emulsifier is between about 2:1 and about 1:2. In some instances, a ratio of the volume of the essential oil to the volume of the diluent is between about 1:4 and about 1:8. Other implementations are also disclosed.

Abstract: In an apparatus for generating variable length codewords c(a.sub.i) and c(a.sub.j) responsive to corresponding fixed length codewords b(a.sub.i) and b(a.sub.j), where a.sub.i and a.sub.j are source alphabet characters, a.sub.i .epsilon. A.sub.1 and a.sub.j .epsilon. A.sub.2, ambiguity arises whenever any fixed length character to be encoded can instantaneously represent source characters a.sub.i and a.sub.j drawn from two or more dissimilar alphabets i.e. A.sub.1 or A.sub.2. This is resolved by the inclusion of a Markov processor in combination with the apparatus. The processor establishes the point in the sequence when transitions occur between fixed length characters in one alphabet to fixed length characters in another alphabet by the message context. The processor includes a map of state and transition paths.
