An identification apparatus for infants utilizes a pair of elastic bands fabricated from a rubber-like material each having different peripheral lengths. The larger band is adapted for engagement about the wrist of an infant, while the smaller band engages an index finger of the infant. The elastic bands are joined by an elongated transparent strap having the ends thereof fastened to the bands. An elongated sheet of paper-like material is secured within a cavity formed by folding over each elong...

A fingerpress is formed by pressing a finger against the back surface of a transparent glass plate and holding it in a predetermined position thereon. This fingerpress is interrogated by a light beam directed through the front surface of the glass plate. The interrogating beam is partially reflected at the back surface to provide a signal beam carrying fingerpress information. The signal beam is created by virtue of the optical discontinuity between the glass plate and the fingerpress. There is ...

A method of determining whether a diamond is the same as or different to a known diamond characterized by the steps of producing one or more records of internal defects of the diamond using X-ray topography and comparing the record or records so produced with a similar record or records produced from the known diamond.

An identification display formed by three sheets laminated together and comprising a peel-off base layer secured with adhesive to the bottom side of an intermediate layer and a top layer removably secured to the top side of the intermediate layer. The peel-off base layer is removable to allow the intermediate layer to be secured to an object for identification purposes. The top sides of the top and intermediate layers have contrasting colors. A matrix of figures of a predetermined shape are cut ...

An identification system comprising a plurality of differently frequency coded markings including mechanical vibrating means, and a detector device for detecting the frequency or combination of frequencies of the vibrating means. The vibrating means of the various markings are preferably made from identical comb-like members having teeth which are vibratory with different natural frequencies and of the type used in small music boxes. The different frequency codes may then be obtained by removing...

An identification system includes means for scanning an identity pattern in a predetermined manner and correlating previously-obtained recognition data with information derived therefrom to determine a positive identification. In obtaining recognition data, the identity pattern is scanned and digitized in a predetermined manner, and then analyzed and sorted to provide prominent information most likely to be recognized in subsequent identity verifications with the original recognition pattern. In...

A carrier for holding an identification strip and adapted to be mounted on one edge of a register means. A first wall is affixed to a common wall to define a pocket in which the identification strip is received. A second wall is affixed to the common wall to define a second pocket. A plurality of signal means are disposed within the second pocket. Each of the signal means is selectively movable to be brought adjacent to and away from a respective portion of the identification strip. In one embod...

A palm pattern detector detects a palm pattern and produces an analog signal corresponding to the palm pattern. The analog signal is converted into a palm bit pattern corresponding to a palm pattern comprised of a number of bit data. Bit data corresponding to the contour of a palm from the palm bit pattern is read out and a contour bit pattern is formed. A displacement between adjacent bit data of the contour bit pattern is detected and is coded into slope code information. A slope change betwee...

An electronic identification and recognition system including a portable radio frequency signal generator having a circuit for repeatedly generating and transmitting an identifying signal having predetermined characteristics of frequency and pulse length. A single crystal determines the radio frequency signal and the two modulating square wave rates, and the bit data rate, so that synchronism with a remote receiver is readily obtained. A low level of transmitting power is chosen to allow non-int...

A device for identifying a coded key or the like. A coded key member is inserted into a housing. A Moire interference pattern is produced by a first screen positioned on the key to be moved into registry with a second screen mounted in the housing. The first screen forms non-readable coded information and the second screen forms a code-key. Decoded information produced by the Moire interference pattern is opto-electrically read and a corresponding electrical signal is generated.
