The invention provides compounds of Formula I: ##STR00001## wherein Azabicyclo is ##STR00002## W is a six-membered heterocyclic ring system having 1 2 nitrogen atoms or a 10-membered bicyclic-six-six-fused-ring system having up to two nitrogen atoms within either or both rings, provided that no nitrogen is at a bridge of the bicyclic-six-six-fused-ri- ng system, and further having 1 2 substitutents independently selected from R.sub.3.These compounds may be in the form of pharmaceutical salts or compositions, may be in pure enantiomeric form or racemic mixtures, and are useful in pharmaceuticals to treat diseases or conditions in which .alpha.7 is known to be involved.

A projector for use with a light source and including a shutter assembly having a multiplicity of pixel light valves and a color separator disposed intermediate the light source and the shutter assembly and spaced therefrom and providing a plurality of spatially separated differently colored light beams, wherein the plurality of spatially separated differently colored light beams are in predetermined registration with the multiplicity of pixel light valves.

A projector for use with a light source and including a shutter assembly panel having a multiplicity of pixel light valves overlying an array of interspersed shutter pixels each of which transmits only one of a plurality of colors, and a color filter disposed intermediate the light source and the planar shutter and spaced therefrom and having an array of interspersed filter pixels, each of which only transmits only one of a plurality of colors, wherein the array of interspersed filter pixels is in light and color registration with the array of interspersed shutter pixels, such that generally light of a given color impinges on a shutter area of the same color.
