Filed: 2001-12-26
Abstract: PURPOSE: A written number sequence recognition method is provided to split the closely written numbers by using unique structural feature data of numbers and a recognition result, and to recognize each written number. CONSTITUTION: The method comprises several steps. A number recognition system receives a sequence of closely written numbers extracted from a document made with various written types of users(S1). The number recognition system smooths an indented number image(S2). The system searches for connection elements in order to classify the number types(S3). The system checks whether the number sequence is closely written(S4). In a case that the number sequence is closely written(S5), the system extracts a profile for the closely written numbers from the number image(S6). Then, the system splits the profile into assistant images by using candidate split points(S7), and calculates a split reliability value for each assistant image by using a defined split error function(S8). The system selects the assistant image of the highest split reliability value as a number image(S9). In a case that the number sequence is not closely written in the step S4 or the step S9 is performed, the system extracts feature data from the number image(S10), recognizes the corresponding number(S11), and in a case that there exists the next number image, the system repeats the step S4.

Abstract: An apparatus and method of forming filament circuit patterns with planar and non-planar portions and interconnection cards, smart cards or optical fiber circuit cards formed therefrom are provided. A filament circuit path is scribed by moving a filament guide and a substrate relative to one another, and dispensing a filament on, or in the vicinity of, a surface of the substrate. The filament or the substrate or both have adhesive surface(s). The adhesive surface is capable of being adhesively actuated by application of energy. Energy is applied simultaneous with, or subsequent to, scribing. A portion of the filament circuit pattern is planar and another portion is non-planar. The non-planar portion traverses but does not contact or adhere to a pre-selected area of the substrate. The pre-selected area corresponds with a pad, a contact pattern, a hole, a slot, a raised feature, a part of the previously scribed planar portion of the pattern, and a filament termination point. Alternately, the non-planar portion may be embedded below the surface of the substrate. Another planar portion of the filament circuit traverses the non-planar portion but does not contact or adhere to a pre-selected part of the previously scribed non-planar portion. According to the above method wire-scribed circuit boards are formed including interconnection cards, smart cards or optical fiber circuit cards.
