Abstract: An elongated playing surface includes: a long axis, a rigid planar cue section at one end, at an opposite end a rigid planar object section rotatable about the long axis, and a mid section twistable about the long axis interconnecting the cue and object sections. The game is played with a cue ball, object balls and cue stick. End and side rails confine the balls atop the playing surface. One end rail, affixed to the object section, defines one or more openings at which are disposed respective ball pockets. The object of the game is to drive the object balls into a pocket by striking them with the cue ball driven by the cue stick. From time to time a mechanism tilts the object section and twists the mid section laterally about the long axis causing balls on said sections to roll according to gravity, making them moving targets.

Abstract: Binary encoded information having a word size of 3N bits, where "N" is a positive integer, plus a parallel data clock are converted to corresponding control signals. Signal drivers with three-state outputs respond to the control signals and communicate corresponding signals via transmission lines, one transmission line per signal driver, to receiving circuits capable of detecting three-state signals, an embodiment of said circuits produce bipolar signals corresponding to the state of the transmission lines with which they communicate. A code converter produces binary signals and a data clock corresponding to the bipolar signals from the receiving circuits. The net result is that the binary word and data clock produced at a receiving end of the transmission lines logically matches the binary code and data clock applied at a sendng end, and that the produced data clock has the same timing relationship with the received binary word as does the originating data clock have with the originating binary word.

Abstract: Trinary digital information is communicated over a pair of electrically conductive lines terminated line to line at at least one extremity by an impedance which generally matches the characteristic impedance of the two lines with respect to each other. One or more transmitters in electrical communication with the two lines selectively impose a first potential difference, a second potential difference distinct from the first, or no potential difference across the lines. One or more receivers in electrical communication with the two lines sense the first potential difference and interpret that as a first logical state, sense the second potential difference and interpret that as a second logical state, and sense no potential difference across the two lines and interpret that as a third logical state.
