Abstract: An electronic organ with tone generators that are coupled to a loudspeaker by depressing key-operated switches, wherein each switch provides a resistance dependent upon the pressure applied to the key so that the musician can control the loudness, attack and decay of a musical note. Each switch includes a highly compressible resistance member whose resistance changes greatly with degree of compression, a first conductor which supports an upper end of the resistance member, and a resilient second conductor normally spaced below the resistance member. Manual depression of a key deflects the lower switch conductor up against the resistance member and compresses it in an amount dependent upon the pressure applied to the key. The fact that the resistance member initially has an extremely high resistance when the first contact touches it, prevents the production of a ''''popping'''' sound as the key is depressed.

Abstract: A toy which senses the color of a target area to select an appropriate output, one of such toys being a rifle which can be aimed at a target device to register whether a hit has been made. The rifle includes a lens which focuses light from the precise direction in which the rifle is aimed onto two identical photocells. A red filter is placed in front of a first of the cells while a neutral density filter is placed in front of a second cell, so that when the rifle is aimed at a red target the red-filtered cell generates a larger output than the other. A detecting circuit determines when the output from the redfiltered cell is greater than that from the other to ring a bell in the gun that indicates a hit. The detecting circuit is activated only at the instant when a child first depresses a trigger on the gun.
