Abstract: A discrimination apparatus for deriving pattern recognition information by selecting predetermined components of a video image for generating a narrow-width identification signal. This is achieved by removing the higher frequency components of the video image of the object to be identified and generating a frequency information signal and an amplitude information signal of the unknown pattern. These information signals are then compared with known amplitude and frequency information signals of known patterns stored in a data base. An identification is made when the respective signal match within predetermined tolerances and associated information is output in response to this identification.

Abstract: A tampon (10) designed to eliminate the hazards of toxic shock syndrome or dysmenorrhea by incorporating an antibacterial agent (or agent effective against other microorganisms) into the tampon (10). The antibacterial agent suspended in an adhesive is coated onto a cylindrical insert of absorptive material (12), a tubular applicator container (22), and a plunger (26). On contact with body fluids the antibacterial agent disperses, preventing development of the organisms which produce the toxins which cause toxic shock syndrome.
