Abstract: Biometric facial comparison is deployed in a novel way to improve screening of applicants across multiple branch locations, preventing common forms of application fraud. The biometric facial comparison software is located at a computing location (20), readily accessible from a first applicant screening branch (30) and a subsequent applicant screening branch (40), by means of a communication network (10). The biometric facial screening is fast, affordable, nonintrusive, and takes place in person in the branch. Even if false identification documents are used, perpetrators will be automatically detected as they attempt to go from branch to branch making bogus transactions. Patterns of fraudulent behavior are detected even if no prior transaction is yet known to be fraudulent, and even if the applicant's face does not match the face of any known perpetrator.

Abstract: An automatic engraving system scans an image such as a photograph, samples and resizes the image to provide a masterized gray scale data base of the image. The image is then logarithmically corrected and noise is removed from the image using the Outlier noise reduction method. The Outlier noise reduced image is then smoothed and edge detection methods are used to provide an output that represents the initial image filtered smoothed and edge detected. The edge detection image is then converted to a bilevel image using thresholding. The bilevel image is then converted to a vector form and speckle noise removed. The speckle noise removed image is then converted to a vector engraving file which is sent to an engraving machine. The engraving process then can batch create one or more than one image or multiple numbers of a single image. The output can be printed rather than engraved to produce the artistic effect of traditional engraving on paper.

Abstract: A substantially stable, crystalline dipotassium N-chloroimidodisulfate is useful as a bleach to remove stains from soiled fabrics when dissolved in an aqueous solution.

Abstract: In an automatic steering system for directing a moving body, said system ng provided with reversibly-motorized depth steering gear including two motor reversing circuits, one, upon energization, setting said gear for climb and another, upon energization, setting said gear for dive, a pendulum mounted for swinging movement in either of two directions relative to said body and having contacts adapted to close one of said climb and dive circuits depending on the direction of said relative swinging movement, and a follow-up link transmitting steering movement of said motorized gear to said pendulum contacts thereby affecting the energization of said circuit.
