摘要: A pressure transducing apparatus which is responsive to the variations are produced when an individual signs his signature, for generating electrical signal representative of such characteristic use in a signature identification system. The employs handwriting surface positioned receiving handwritten by pair soft rubber supports. permanent magnetic bar affixed underside writing and vertically displaced as applied varied. sensing coil around path vertical displacement that current generated response member so provide writes signature.
