Abstract: A passenger seat assembly for a vehicle, particularly an aircraft, which is adapted to provide self-contained, individual seating and sleeping accommodation for a passenger, said seating assembly including a supporting structure (42) for supporting said assembly off the floor of a vehicle; one or more movable, passenger-bearing, structural components (71, 72); and means for connecting said movable, structural components to said structure such that said components can be selectively moved between a seat configuration, in which a plurality of passenger-bearing surfaces on said one or more structural, movable components (71, 71) or said supporting structure form a seat for the passenger, and a bed configuration, in which a plurality of said bearing surfaces (47, 48, 67, 74, 76) are disposed substantially coplanarly and substantially contiguously to form a bed for the passenger; characterized in that at least one of said movable components (72) is double-sided, comprising first and second opposite sides, one of s

Abstract: A circuit for generating alternating repeat keying signals in an electronic keyboard musical instrument includes a clock, a logic circuit responsive to the keys of the instrument and to the clock for producing an alternating sequence of logic signals corresponding to each of the keys, the phase of the sequence corresponding to each undepressed key being the same as the phase of the sequence corresponding to the previous key and the phase of the sequence corresponding to each depressed key being opposite that of the phase of the sequence corresponding to the previous key and a plurality of output gates each developing a keying signal in response to the depression of a respective one of the keys and the logic signals of the corresponding sequence assuming a predetermined state.
