A raster-type personal display is provided by vibrating an array of fiber optic filaments (32) between display limit (52, 54) by means of an electromechanical exciter (36). One end of the fiber optic filaments (32) is cantilever mounted to an array of light emitting diodes (34), with the second end of the filaments free to be vibrated by the exciter (36). Drive signals for energizing the light emitting diodes (34) are generated by a symbol generator (38) that receives synchronization pulses from a position detector consisting of a light source (58), a shutter (56) and a light responsive pickup (60).

A helicopter mast is driven by a transmission with a swashplate individually linked to pitch horns on each rotor blade. At least four actuators are coupled to the swashplate, three of which normally control the attitude and position of the swashplate. A separate power unit is provided for each actuator, each power unit being independently driven from the transmission. Means are then provided to shift control of the swashplate from one of the three actuators to a fourth actuator upon any one becoming disabled.

Control system for redundant swashplate drive

An alarm control circuit, designed as a unit package to be mounted in the interior of a vehicle, is adapted for connection to the ignition switch circuit, to a vehicle door or other closure operated light switch circuit, and to the vehicle battery, with the output being connected to the vehicle horn circuit. The alarm control circuit is completely automatic when operated through the vehicle ignition switch and a vehicle closure switch, and sounds the vehicle horn intermittently when a closure is opened by unauthorized persons. The alarm control circuit may also be connected to the vehicle headlight switch circuit to provide the ancillary function of a warning signal, should the headlights be left on with the ignition switch off.
