Title: Process for encrypting a fingerprint onto an i.d. card
Inventor: JOHNSON NELDON P
IPC: G06F21/00
Filed: 1996-02-28
Granted: 2000-05-16
Abstract: The invention and process utilizes any number of biological parts to provide a proof of legitimacy and from them generate and verify a personal identification card (ID). This rendition of the invention deals mainly with fingerprints, but does not preclude the use of other biological parts. The invention is unique in being able to render complex forms into unique biological characteristic codes of the unique biological parts, especially the fingerprint, and then to be able to encode that code onto the magnetic strip of an ID card or credit card. The invention renders complex biological forms into numeric representations of the unique biological parts and especially the fingerprint. The number generated thereby is encoded onto the magnetic strip of an ID card or credit card. A comparison is made of the live biological part to the number on the card to identify that the person using the card is the legal owner of the card, thus either automatically identifying the person as the legal card holder. This makes it possible to use the card safely without the need for personal attendants to ensure that the transaction is carried out by the legal owner of the card.

Abstract: A mechanism for adjusting the height of a back relative to a seat in a seating assembly having a support member interconnecting the seat and the back.  A recess is formed in an upright portion of the support member, and a toothed rack is secured within the recess.  The upright portion of the support member is slidably engage-able with a box-like unit secured to the back, and an engagement member is mounted to the box-like unit and disposed within the recess formed in the support member upright portion.  The engagement member includes engage-ment structure selectively engageable with certain of the rack teeth to fix the position of the back relative to the support member.  A biasing element urges the engage-ment member to an engagement position in which the en-gagement structure is engaged with certain of the one or more teeth.  The biasing element also functions to retain the engagement member in a disengaged position when the back is fully raised, for enabling the back to be lowered without engagement of the engagement structure with the rack teeth.  Release structure is engageable with the engagement member when the back is fully lowered so as to disengage the engagement member from the biasing element in preparation for subsequent positioning of the back by raising the back relative to the seat.

Abstract: In a multi-value modulation system such as M bits/1 symbol, a pattern matching apparatus is arranged by a coincident bit number detecting circuit for detecting a coincident bit number between a received symbol and the known pattern of a receiver within 1 symbol; a delay circuit for delaying the detection result; and an adder. Then, a coincident bit number between the received 1 symbol (M bits) and 1 symbol (M bits) of the known pattern is detected.      These detected bit numbers are added to each other, so that when a length of a UW pattern is N bits, the total number of adders can be reduced to N/M.

Abstract: A pressure sensing system employs a plurality of pulsed, single-wavelength optical signal sources, each emitting a distinct wavelength, whereby a multiplexed incident beam is generated. The incident beam is split into a first portion directed to first photodetector means that generate a reference signal for each wavelength, and a second portion that interrogates one or more Fabry-Perot pressure sensors. The interrogation beam portion is phase-modulated by gap width variations in the sensor(s), and is transmitted to second photodetector means that generate a measured intensity signal for each wavelength. For each wavelength, the ratio of the measured intensity signal to the reference intensity signal is taken, and yields two terms, one of which is an interference term that is proportional to the cosine of the Fabry-Perot phase shift angle .phi., which is a function of the gap width. By choosing wavelengths that are in quadrature relationship for a nominal Fabry-Perot gap width, the algebraic differences can be taken among the ratios to yield two expressions proportional, respectively, to the cosine and sine of the phase shift angle .phi.. An arctangent calculation is used to obtain the measure of .phi., which is proportional to the gap width, which, in turn, is a known function of the pressure applied to the sensor. The optical sources may be pulsed sequentially to provide a time division-multiplexed incident beam, or simultaneously to provide a wavelength division-multiplexed incident beam.

Abstract: Methods and apparatus are disclosed for causing the optical center of the ey e to align "HIGH point" of the anterior surface of the cornea. In accordance with one aspect of the invention relating to corneal ablation procedures, the "HIGH point" ( 14) of the eye is used as the pole of a spherical surface which is fitted approximately to a portion o f the anterior surface of the cornea within a "bounded region" (16). For corneal ablation procedures, the "bounded region" comprises a generally inverted cup shaped region of the anterior surface of the eye bounded at its periphery by a plane (BP) which is substantially perpendicular to a local z-axis. During the operation local high points which project above the spherical surface are ablated. According to another aspect of the invention relating to radial keratotomy procedures, a pair of incisions (b, b') in the plane of a "great circle" are formed in the cornea to weaken and flatten it. As used herein, a "great circle" is formed by a plane containing the "HIGH point" and parallel to the local z-axis. The "bounded region" for radial keratotomy procedures is defined absolutely in terms of a circle projected onto the corneal surface which is centered about an axis passing through the "HIGH point" and parallel to the z-axis.
