A sensor array system for detecting the position of an object or energy source. The system includes a plurality of sensors, each sensor having a limited field of view and being capable of detecting an object or energy source that is positioned within its field of view. The fields of view of at least some of the sensors overlap the fields of view of other sensors, and the overlapping fields of view define unique spatial regions. A data acquisition system is operatively connected to the plurality of sensors and is used to determine which sensors simultaneously detect an object or energy source, thereby determining the unique spatial region in which the object or energy source is located.

Sensor array system for object position detection

A pressure-responsive mechanical switch for use in conjunction with integ rocket-ramjet engines. The switch may only be activated when two pressure sources acting thereon meet certain preselected conditions and includes a pair of selectively interlocking pistons mounted within a pair of bores disposed in a housing. The pistons are independently acted upon by the forces produced by pressure sources to effect activation of the switch.
