Publication number: 20240094690Abstract: The present disclosure belongs to the field of estimators, and provides a generalized estimator (GE), and a generalized disturbance rejection controller (GDRC) and a design method thereof. The GE includes an inner-loop estimation controller and a nominal model module of a controlled object. The inner-loop estimation controller transmits a control signal to the nominal model module. The nominal model module includes a nominal model of the controlled object. The GE is structurally uniform, and functionally interchangeable. With the structure of the GE, the typical disturbance rejection controller (DRC) is unified to a same control framework to obtain the GDRC that is more universal. The GDRC can design different control strategies according to existing conditions of most systems.Type: ApplicationFiled: October 28, 2022Publication date: March 21, 2024Inventors: Shaojie LIU, Donghai LI, Min ZHU

Publication number: 20240076543Abstract: The present disclosure provides a weakly-confined semiconductor nanocrystal, a preparation method therefor and use thereof. A size of the nanocrystals is larger than an exciton diameter thereof; excitons in the nanocrystal are dynamic excitons, electron-hole Coulomb interaction of the dynamic excitons is insufficient to bind electrons and holes into stable bound excitons at operating temperatures, and the electrons and the holes of the dynamic excitons are constrained by boundaries of the nanocrystal. Since the excitons in the weakly-confined nanocrystals herein possess the characteristics of dynamic excitons, the nanocrystals herein possess unique optical and photoelectric properties distinct from conventional semiconductor nanomaterials. It holds unique value for applications requiring broad-spectrum emission (such as lighting) and significant importance for photovoltaic solar devices, photoelectric detectors, and photocatalysis.Type: ApplicationFiled: September 4, 2023Publication date: March 7, 2024Inventors: Xiaogang PENG, Liulin LYU, Jiongzhao LI, Shaojie LIU

Publication number: 20230080337Abstract: Disclosed is a method for automatic classification of pathological images based on a staining intensity matrix. This method directly extracts the staining intensity matrix irrelevant to a stain ratio, a staining platform, a scanning platform and some human factors in the pathological image as the feature information of classification, without restoring normalized stained images, while retaining all impurity-free information related to diagnosis. It avoids the phenomenon that the diagnostic effect of the existing computer-aided diagnosis method of pathological images based on the traditional color normalization method changes with the changes of the selected standard pathological sections. Moreover, it avoids the error introduced by the need to restore the stained image, and has a higher diagnostic accuracy and a more stable diagnostic effect. At the same time, the method can realize the diagnosis of pathological images in a shorter time, which is easy to realize and more practical.Type: ApplicationFiled: March 23, 2022Publication date: March 16, 2023Inventors: Wentao ZHU, Mengfan XUE, Shaojie LI, Defu YANG

Patent number: 7626436Abstract: An Automatic System Clock Detection System (ASCDS) may provide integrated circuits (ICs) with the capability to detect the frequency of an external crystal oscillator or clock source, and adjust the IC's internal PLL accordingly for proper IC operation. The frequency detection and PLL adjustment may be performed without any additional pins on the IC, and/or without requiring any additional external information. The ASCDS may be configured with an internal ring oscillator, which may be generated from standard logic elements, a watchdog counter, and an input clock counter. When the IC comes out of power on reset (POR), the ASCDS may compare the input clock counter with the watchdog counter, and determine the clock frequency of the input clock. It may then set the PLL parameters to ensure correct IC operation.Type: GrantFiled: November 14, 2007Date of Patent: December 1, 2009Assignee: Standard Microsystems CorporationInventors: Shawn Shaojie Li, Akhlesh Nigam, Mark R.
