Abstract: An illuminated three-dimensional model is fabricated by importing or generating a digital dataset representing the surface of a three-dimensional source surface; producing a three-dimensional model of the three-dimensional source surface from the digital dataset, wherein the three-dimensional model has a translucent or diffusive surface and a base surface; and mounting a projection device in a configuration such that distinctive patterns of light are directed from the projection device through the base surface of the three-dimensional model to selectively illuminate at least a portion of the translucent or diffusive surface of the three-dimensional model.

Abstract: A serial Huffman decoder that is concise and capable of extremely high rates of operation is described. Optimal speed is attained because the critical-path of an embodying circuit has only a memory in the critical path. No other functions or operations are entailed. This being the only unequivocally essential device in the implementation of a mapping such as Huffman, the critical path is blatantly optimal. The codetable, composed of a specially modified Huffman binary tree, is much more compact than the typical Huffman binary tree.

Abstract: A method of processing multiple VLC data elements concurrently. A system realizing this method comprises a plurality of encoders under control and a plurality, typically like in number, of decoders under separate, but accorded control. Furthermore, a means of communication from the former to the latter is incorporated in which ordinal and temporal correspondence is established between particular encoders and particular decoders. Encoder control provides an ordered symbol assignment strategy across all encoders. Decoder control detects the encoder assignment strategy and applies it to the task of restoring the original output order among all decoder outputs.

Abstract: A processing means is described for the variable-length encoding of digital signals. The resultant serial encoder admits symbols at data-dependent intervals and progressively releases one bit of encoded output each cycle. The encoder comprises storage, a shifter and a simple pattern tester. Excepting the pattern tester, no arithmetic operations are involved. These three parts are arranged such that processing speed is limited by the greater of the retrieval delay from storage and the delay of the pattern tester. This arrangement is made feasible by an implicit means of codeword length storage. Optimal encoding rates for a serial encoder may hereby be obtained.
