  • Patent number: 11615634
    Abstract: A system, method, and computer program product provides a way to separate connected or adhered adjacent characters of a digital image for license plate recognition. As a threshold processing, the method performs a recognition of character adhesion by obtaining character parameters using an image processor. The parameters include a horizontal max crossing and a ratio of width and height. A first rule-based module is used responsive to the character parameters to distinguish the adhered characters (character adhesions) that are easy to judge, leaving the uncertain part to a character adhesion classifier model for discrimination. Character adhesion data is obtained by data augmentation including the adding of a random distance between two single characters to create class like adhered characters. Then the character adhesion classifier model of single character and character adhesion data is trained. Any uncertain part can be distinguished by the trained character adhesion classifier model.

  • Patent number: 11605610
    Abstract: This document describes systems and techniques of a depth-adaptive mechanism for ball grid array dipping. In an aspect, a depth-adaptive mechanism having a tensioned mesh is positioned in a reservoir filled with flux. When solder balls of an integrated circuit component are dipped into the reservoir of flux, the solder balls are pressed up against the tensioned mesh. The tensioned mesh is configured to, first, elastically deform under the downward force applied by the solder balls and, second, provide an equal and opposite pushing force in order to facilitate solder ball extraction. In so doing, the solder balls of an integrated circuit component can be more easily extracted from flux when deep ball grid array dipping is performed.
