Methods and systems for training a computer to recognize and verify an individual's signature are provided. One illustrative method extracts a plurality of both global and local features from a relatively small sample of handwriting samples. In one such embodiment, only 5 samples are needed from an individual without requiring forgeries. In yet another embodiment, only three global parameters are utilized, thus reducing the complexity, and processing power, of the system. Utilizing such few glob...

A tray is adapted to be supported on an elevator mechanism and moves vertically by the elevator mechanism to pick up a shingled array of signatures which are supported on edge in an inclined position adjacent the elevator mechanism. The tray includes a generally horizontally extending support portion adapted to engage the lower edges of the signatures as the tray is raised. A member located at one end of the tray has an inclined surface against which the last signature at one end of the tray res...

The present invention provides systems and methods for protecting transaction information stored in a database of a gaming network. To accomplish this, a transaction signature is generated each time the user completes a transaction on a gaming machine. The transaction signature is generated using transaction information from a particular transaction. The transaction signature and transaction information are stored together in a network database. Upon subsequent access to the transaction informat...

The invention relates to the generation of digital signatures by the use of which the legally binding nature of a digital signature is enhanced. For this, an expanded digital signature is created which, in addition to the hash, contains other information, in particular information identifying the hardware and software environment used in generating the signature.

One or more electronically-accessible media including electronically-executable instructions that direct an apparatus to perform actions including: inserting a type signature tag into a serialized binary blob to serialize an object, the type signature tag including a type signature based on an object type of the object; and transmitting the serialized binary blob. An arrangement including: a signature table having multiple entries, each respective entry of the multiple entries associating a resp...

A radar method and system of distinguishing radar echoes of discrete and point targets such as moving and motionless aircraft, trucks, etc., from reflections from distributed targets such as the earth's surface, the radar echoes resulting from a succession of single pulses transmitted from a single antenna. The electrical phase within the returning radar echoes is measured by means of a coherent CW oscillator operating at the frequency of the transmitted radar signal. The measurement of phase as...

Each signature feeder along a collating conveyor is selectively actuated under control of coded signals containing mailing information. A dot matrix printer, located between the feeders, is responsive to the coded signals to selectively print custom information within books of signatures. A second dot matrix printer, located after the stitcher and trimmer, prints mailing labels under control of the coded signals. Optical scanners located downstream of the dot matrix printers scan each line of po...

Apparatus for use with printing presses to cut, fold and trim each individual signature and deliver the completely trimmed signature to succeeding folding or stacking stations.

The automatic signature opener has a continuous conveyor for the signature, a surface covered with pressure-sensitive adhesive which is brought into contact with the top sheet of the signature to lift the top sheet, a separating member for insertion between the top sheet and the remainder of the signature to hold them apart, and a member for pulling the top sheet of the signature away from the adhesive surface to release the signature from the adhesive surface.
