Abstract: A system and method for monitoring and safety related systems (SRSs) in a Secure Compartmented Information Facility (SCIF) that addresses concerns for security of electronic emanations from equipment in the SCIF. A fiber optic link connects an optical receiver located within a SCIF and an optical transmitter located outside the SCIF. Alarm signals generated by an SRS located outside the SCIF are detected and sent to the optical receiver over the fiber optic link. The optical receiver converts the optical signals to electrical signals and directs the signals to alarm devices within the SCIF. Additionally, an audio signal generated at the location outside the SCIF is converted to an optical signal and then reconverted to an audio signal by the optical receiver for broadcast over a speaker located within the SCIF. A tone signal generated at the optical transmitter is continuously sent over the optical fiber link to the optical receiver and the SCIF speaker.

Abstract: A device for forming a jack-o-lantern, which is attached embracingly to a pumpkin and comprises two curved plates engaging opposite sides of the pumpkin and retained in place by cords which are laced through the adjacent edge portions of the plates. In one plate, called the main plate, are holes generally locating the eyes, nose and mouth which are to be cut from the pumpkin. A tool having a cutter is provided for each of the eyes, nose and mouth, and these are respectively mounted on the main plate. By manipulation of the tools, holes are cut appropriately in the pumpkin. The tools are operated individually by screw action, and after the forming operation is completed, the plates are unlaced and removed from the pumpkin.
