Apparatus for detecting and identifying, by video imagery, an object such as a helicopter, having a characteristic temporal signature containing phase and magnitude information. The object is acquired and the video signals are stored and then temporally filtered by a FFT on a pixel to pixel basis. The magnitude and phase of pixel at a predetermined frequency is determined and compared with periodic frequencies generated by known objects, such as helicopter rotors, to determine if the frequency generated by the object matches any of the known frequencies. Further processing determines the number of blades and directions of rotation of the blades which removes ambiguities from frequency only processing.

System for detection and recognition of an object by video imaging means

A device for applying adhesive onto a fiber, such as an optical fiber, is located between the fiber supply spool and rewinder and comprises a covered cup for holding liquid adhesive, and a drying chamber. The cup has first and second bores for passing the fiber therethrough and is suitably insulated from external temperature changes. The entrance of the drying chamber is coupled to a side of the cup so that it surrounds the second bore.
