| Number | Title | Issue Date |
| 4475235 | Signature verification sensor A sensor having a particular application in the field of signature verification is disclosed. In the presently preferred embodiment, two plates are disposed in a spaced apart relationship and constructed to provide a plurality of electrical capacitors. Pr... | 10/02/1984 |
| 4344135 | Dynamic creation of signatures In order to verify the authenticity of the signature of an individual, first a sample signature is written with a pen which can generate electrical signals representative of the forces exerted in the plane of the paper in the process of writing. These sig... | 08/10/1982 |
| 4156911 | Dynamic re-creation of signatures In order to verify the authenticity of the signature of an individual, first a sample signature is written with a pen which can generate electrical signals representative of the forces exerted in the plane of the paper in the process of writing. These sig... | 05/29/1979 |
| 4143357 | Transducing device for signature verification system A transducing device converts to representative electrical signals those force variations which are produced by the act of a person writing a signature. In the device, a signature writing surface is provided, and is part of an arm attached by resilient me... | 03/06/1979 |
| 4040012 | Handwriting verification system Identification of a specimen signature is provided by comparing the specimen with a previously recorded template signature. The comparison is performed by recording, for both specimen and template signatures, signals representing forces in three direction... | 08/02/1977 |
| 4040011 | Identification based on handwriting samples An individual, who is to be subsequently identified, first signs his signature, hereinafter called a template signature, with a special pen, attached to circuits, which produce digital sample signals from which a set of parameters of his signature are der... | 08/02/1977 |
| 4040010 | Identification by handwriting verification A person, who is to have his identity verified, first writes his signature or any other appropriate group of characters or symbols several times with a special pen which produces signals representative of the writing forces in the plane of the paper and t... | 08/02/1977 |
| 4035768 | Personal identification apparatus Apparatus used in identifying a person by means of pressure patterns associated with a signature comprises first and second spaced and parallel planar conductor elements with a lamina of elastomeric material on an exposed surface of one of the elements to... | 07/12/1977 |
| 4035769 | Method and apparatus for recording a signature The pressure exerted while writing a signature is transduced to an electrical analog signal which is periodically converted to a binary coded number representing the average amplitude of the pressure between periodic samplings.... | 07/12/1977 |
| 4008457 | Pressure transducing apparatus for use in a signature identification system A pressure transducing apparatus which is responsive to the pressure variations which are produced when an individual signs his signature, for generating an electrical signal representative of such characteristic pressure variations for use in a signature... | 02/15/1977 |
| 3991402 | Pressure transducing platen for use in a signature identification or verification system A pressure transducing apparatus which is responsive to the pressure which is exerted by an individual when he signs his signature for generating an A.C. electrical signal representative of the characteristic variations in pressure produced when an indivi... | 11/09/1976 |
| 3959769 | Method and apparatus for recording a signature The pressure exerted while writing a signature is transduced to an electrical analog signal which is periodically converted to a binary coded number representing the average amplitude of the pressure between periodic samplings.... | 05/25/1976 |
| 3956734 | Platen having a pressure-responsive transducing means for use in a signature-identifying system An apparatus which is responsive to the pressure variations inherent in an individual's act of handwriting a signature for generating electrical signals representative of these characteristic pressure variations for use in signature identification systems... | 05/11/1976 |
