An identification system for individuals which provides a three point identification check at point-of-transaction to assure accuracy is disclosed. The system utilizes an individual fingerprint and an identifier which can be correlated to the fingerprint and to a listing of valid identifiers. In carrying out the system, an identification card is used which has the individual's fingerprint, a grid superimposed over the fingerprint, and an identifier printed thereon. The identifier is made-up of a...

A container to be attached to a shoestring or the like and adapted to contain information regarding the medical condition and/or identification of the wearer. The container is made of two halves formed from a resilient plastic material, which define between them a cavity in which a specially-shaped piece of paper with the necessary information can be placed.

A finger pressed against a platen provides a fingerprint object which is scanned by an interrogating beam of collimated light in the form of a slit and that is linearly displaced across the platen. As the slit-beam scans across the back surface of the platen, the reflected light beam is modulated. The modulated beam is imaged onto a linear array of photodiodes to provide a series of output signals indicative of modulation information. The outputs of the diodes are serially interrogated at each o...

This invention relates to the identification of fingerprints automatically, and more particularly to a system in which conductive contact is made between a finger surface and an array of electrodes with circuit means for dividing the electrodes into groups and logic means for control of the response of the system to predetermined combinations of signals from the electrodes.

An identification system utilizing an identification card which has thereon identifying indicia which is invisible under normal, visible light. The card or other article of identification includes a portion formed with an opening receiving a sheet on which identifying indicia is located, and this identifying indicia includes at least a portrait of the individual who is authorized to use the identification article. The sheet can also carry a signature of this individual, and the nature of the ind...

An identification bracket for students in a class-room. The bracket is adapted to be fixed to the edge of a desk top, including a clamp and a display plate holding on one side an identification panel, namely bearing the name of the student occupying the desk, and on the opposite side with means providing a time table of the student's lecture activities for a week. The display plate can be orientated in any direction with respect to the clamp, so that the student's name can be easily read by the ...

An apparatus for audio identification of a photographic transparency mounted in a slide frame, the slide frame being provided on one face with a resiliently backed strip of magnetic recording tape capable of resolving a 600 microinch signal. The slide frame is positioned for projection of the images on the transparency and a magnetic transducer having a gap width less than 200 microinches is biased against and moved in a straight line along the strip of magnetic tape on the positioned slide fram...

An identification band to be secured to the arm or other limb of a wearer and intended to have the name or other appropriate identification of the person to which the band may be applied. The band comprises an elongated tube of nonelastic material which is preferably transparent, to allow an identification card to be inserted in the tube and to be visible through the wall thereof, bearing the name or other identification of the person. One end of the band has a clip applied thereto while the opp...

A device and method for obtaining an identification pattern of polished gemstones. The device comprises, in combination, means for holding the gemstone in a reproducible position, means for creating a collimated parallel light beam, a lens for projecting a pattern obtained by reflecting the collimated parallel light beam from the gemstone onto a plane recording medium facing a plane reference surface of the gemstone. The distinctive pattern may be projected onto the plane recording medium via be...

A method for comparing the infrared spectrum of an unidentified oil sample to the infrared spectra of a plurality of identified oil samples is disclosed herein. Also disclosed is a method for taking account of the background interference of testing cells when sodium chloride cells are employed for preparing or measuring the infrared spectra. Also disclosed is a method of using aluminum foil strips to separate oil samples from an aqueous environment and as sample cells in the preparation of infra...
