摘要:
A method and apparatus for automatically verifying a signature of an individual is described. The apparatus digitizes an image of the signature and provides a grey scale representation of each pixel. Next, the apparatus determines parameters of this digitized image and compares them to corresponding reference parameter values which were determined from a valid signature. The results of the comparison indicate if the signature to be verified is valid. The parameters include a center of gravity of the pixels within each row and columns of the digitized image, a center of gravity line for the centers of gravity for the rows or columns and the center of gravity for all pixels of the image. Other parameters include the positions of maximum grey scale pixels within each row or column, sums of grey scale values per column or row and the shape of a bow within the signature image.

The invention concerns a method and a circuit arrangement for electrically driving print electrodes in an electroerosion printer by means of driver stages producing relatively strong and relatively short ignition pulses as well as by means of driver stages producing relatively weak burning pulses which are of longer duration than the ignition pulses. The burning pulse is first initiated and if an arc is struck, the ignition pulse is not required. Use of the burning pulse alone produces a sharp edge printing mark. Only if the burning pulse is unable to strike an arc is the ignition pulse delivered to assure that printing occurs.

In an integrated circuit an improved highly integrated semiconductor structure for providing a Schottky diode-resistor circuit configuration is disclosed. Although not limited thereto, the improved highly integrated semiconductor structure has particular utility when employed in a monolithic memory.

Disclosed herein are systems and methods for storing patient medical information on a local processing device, anonymizing a portion of that medical information and storing it on a second processing device, exposing that anonymized medical information to a third processing device coupled to the second processing device through a network, and restricting users of the third processing device to only accessing HIPAA compliant medical information. Alarms are included for indicating the improper transfer of HIPAA data.
摘要:
To obtain a good print quality in metal paper printers, the print current, after ignition of the arc, must be rapidly reduced to a fraction of the value necessary for ignition. For this purpose, two transistor power stages (T3, T4) are connected to the print electrode (2). Their partial currents form the print current, whose rapid reduction after ignition of the arc is obtained by the two transistor power stages being operated at voltages (U2, U3) of different magnitude. The second transistor stage (T4) is operated at a voltage (U3), whose magnitude corresponds to the drop in potential occurring upon ignition between the grounded metal layer (3) of the record carrier (4) and the print electrode. As a result, the second transistor stage is switched off when a diode (D) connected to it becomes non-conductive.

A yieldably supported ramp controls the lowering of a print head onto a record carrier. An elastically deformable element having non-linear deformation characteristics is preferred to define the desired force displacement characteristics.

The invention concerns a method of recording information on an electrosensitive record carrier, preferably a record carrier covered with a metallic or metalliferous layer, by means of a print head movable relatively parallel to the surface of the record carrier and comprising at least one print electrode controllable by print pulses, and a control circuit for the timely generation of the print pulses from digital or analog signals received in such a manner that the duration and amplitude of each print current pulse are chosen so that the print process triggered by the individual print pulse is completed by the time the print pulse stops.

The invention relates to a method and apparatus for transforming an image for classification or pattern recognition. At least two distinct projections are carried out in order to define boundaries and shadows of the transformed image. The transformed image is the basis for further analysis such as the calculation of parameter values to be verified.
