Title: Character recognition
Inventor: SPARR GUNNAR
IPC: G06K9/62
Filed: 1999-08-25
Abstract: The invention relates to a method for character recognition comprising the steps of: detecting a union of characters, preprocessing the union of characters, comparing the preprocessed union of characters with one or more template symbols, and applying a decision rule in order to either reject a template symbol or decide that the template symbol is included in the union of characters. The step of preprocessing the union of characters comprising the steps of: representing the union of characters as one or more curves, and parameterising said curve or curves, and regarding various classes of transformations forming one or more shapes for said curve or curves. The step of comparing comprises the steps of: forming one or more geometric proximity measures, and determining for every shape the values of said geometric proximity measures between said shape and correspondingly determined shapes for the template symbols. Finally, the step of applying a decision rule comprises the step of: selecting one or more template symbols in consideration of said values.

Title: Method for producing a multifocal correction lens, and system for implementing same
Inventor: GIROD DENIS
IPC: B24B41/06
Filed: 1999-08-27
Abstract: The invention concerns a method for producing multifocal correction lenses from semi-finished lenses (1) having at least a first positioning marker M, associated with a correction A called distant vision correction, and a second positioning marker M' associated with a correction B called near vision correction. The method comprises a step which consists in a surface grinding of the semi-finished lens (1) on an internal surface of said lens. The latter is inclined at a specific angle (beta), for example using a wedge, so as to induce a prism of prismatic deviation such that the distant vision and the near vision optical centres are brought together and merge. The invention also concerns a system controlled by a data processing device, for example a micro-computer (8), for automatically carrying out the surface grinding step using a recorded programme and parameters input (80) by an operator.

Inventor: EASON RICHARD
IPC: G07C9/00
Filed: 1999-09-17
Abstract: An information card system that eliminates forgery and illegal use of a card is proposed. An information card stores information data in a memory thereof.  The information data contains inherent data embedded therein according to Steganography. The information card also stores a password for permitting the information data to be read from the memory. A data processing terminal checks a submitted password against the stored password, and permits the information data to be read from the memory when the passwords identify with each other. A  customized key is submitted to extract the inherent data. The inherent data is permitted to be extracted only when submitted customized key is legitimate.  The information card system is possible to both hide the presence of the inherent data and prevent unauthorized extraction of the inherent data because any unauthorized person is unaware of the customized key. Thus, the information card system provides a high level of security.

Inventor: LEAP GERALD L
IPC: B23K3/06
Filed: 2000-06-02
Abstract: An apparatus for processing printed circuit boards including a system for measuring and controlling solder wave height generally comprises conveyor system for transporting printed circuit board through a number of processing stations. The system for measuring and controlling the wave height of solder includes a sensor which is mounted in close proximity to the interface defined between the surface of the solder wave and the bottom surface of the printed circuit board. The sensor is coupled to a micro-controller and the micro-controller is coupled to a pump motor. The pump motor is coupled to a solder bath which generates the solder wave and is controlled to operate at a predetermined speed to maintain a predetermined solder wave height during the process of wave soldering printed circuit boards. The sensor provides a number of voltages to the micro-controller representing the distance between the sensor and the top surface of the solder wave. The voltages are converted into a number of values. The micro-controller includes a comparator which receives the values and compares the values to a predetermined set point to determine whether the solder wave height is too high or too low and the micro-controller further determines whether to respectively decrease or increase the speed of the pump motor.
