Title: Computer-implemented ai method for detecting surface defects of electroluminescent semiconductor panel
Inventor: BOYUAN CHEN
IPC: G06N3/08
Filed: 2021-12-28
Abstract: The present invention relates to a computer-implemented AI method for detecting surface defects of an electroluminescent semiconductor panel, comprising the steps of 5 ﬁrst time of image enhancement processing, marking and transformation of image defects, random distribution of training, veriﬁcation and testing of images, second time of image enhancement processing, establishment of a target detection neural network, data training and obtaining of optimal weight parameters, and AI detection of the panel images. The present invention aims to solve the technical problem that during defect 10 detection of the surface of the EL semiconductor panel, as limited by quality and amount of image datasets and restricted by a singular preprocessing method of image data and a small network scale of a pixel algorithm, the defects are recognized slowly in low precision, and the defects cannot be classiﬁed and positioned accurately. The method is applicable to detection of semiconductor chips and panels made of Si, Ge, AsGa, SiC 15 and the like.

Title: Laryngograph analysis of speech pattern - uses transmitting electrode, carrier oscillator and peak clipping in receiver
IPC: G10L25/90
Filed: 1976-02-24
Abstract: A circuit used for producing speech patterns for analysis and can therefore be used in speech therapy, education and tension detector such as a lie detector. The circuit is used in a larynograph which produces a wave form of the larynx. The system consists of a transmitting electrode, and an oscillator (2) which generates a carrier wave. There is a receiver electrode for the carrier wave which is modulated by the larynx. The receiver contains detectors (1, 3) which separates the larynx wave form. The carrier wave is subjected to peak clipping, also known as slicing, to produce a substraction before detecting the wave form. Slicing control is achieved by means of a feedback signal introduced into a slicing circuit after extracting the DC component from a low pass amplifier. The strength of the feedback signal is regulated (7) and transmitted to the oscillator which feeds the transmitting electrode.

Title: Screen printing system using heated pen - forms stencil by melting areas of wax-impregnated gauze sheet
IPC: B41C1/14
Filed: 1983-10-25
Abstract: The blank stencil tissue (3) is placed on a metal print plate (4) and convered by a frame contg. a gauze sheet (1) impregnated with wax (2). The end of a heated pen (5) is then used to draw the required image on the stencil surface by melting the wax, which is absorbed by the tissue. The curved end of the pen has a point which tapers out into a broader flat area. The width of line can thus be altered by varying the angle between the pen and the gauze surface. A heated plate can then be used to improve the absorption of the wax by the stencil, before using conventional screen printing techniques to make copies. The gauze can be cleaned and re-impregnated for later re-use.

Title: Plant-support ring
IPC: A01G9/12
Filed: 1992-02-26
Abstract: A plant-support ring for connecting a damagable plant stem to a vertical support body, such as a post which has been driven into the ground, is made from plastic and is split at one location. This split is arranged at the end of two limbs which extend substantially radially inwards.
