Abstract: Overhead passenger comfort modules are provided with a module segment having a support frame member which includes a perimetrical trim frame member, and a ventilation system supported by the support frame member. The ventilation system includes a supply conduit adapted to being fluid-connected to a supply of ventilation air, and first and second branch conduits fluid-connected at one end to the supply conduit and terminating in elongate first and second ventilation openings at first and second edge regions of the support frame member. First and second concavely curved edge diffuser portions are provided which are adjacently positioned to and spaced from the first and second ventilation openings respectively.

Abstract: Side-facing belted aircraft seats include a tactile signaling unit to induce movement of the seat occupant. For such purpose, the signaling unit may be provided with a signaling lid covering a female buckle of a lap belt restraint assembly. The signaling lid is moveable between a closed position wherein engagement of a male tab of the lap belt with the female buckle is precluded and an open position wherein engagement of the male tab with the female buckle is allowed. The signaling lid thereby provides tactile stimulation when in the open position thereof to induce the seated occupant to shift on the cushioned seat so that a midsaggital plane of the occupant is aligned with an offset plane of the seat that is offset by a predetermined distance toward one side of the seat relative to a midplane of the seat.

Abstract: A recirculating loop memory array is disclosed adapted for the parallel as well as serial fetching and storing of data while requiring only a single input and single output data terminal. Each loop of the array is provided with a shift register stage for parallel data accessing. A particular recirculating bit in all of the loops can be fetched in parallel into their respective shift register stages and, conversely, the bits stored in the shift register stages can be loaded in parallel into predetermined recirculating bits of their respective loops. The shift register is operated at high speed so that it may be completely loaded or unloaded during the interval between successive steppings of the loops.
