Publication number: 20240153082Abstract: Disclosed is a computer-implemented three-dimensional image classification system (CIS) for processing and/or analyzing non-contrast computed tomography (CT) medical imaging data. The CIS is a deep neural network containing multiple Convolutional Block Attention Module (CBAM) blocks, which contain convolutional layers for feature extraction followed by CBAMs. The CBAM applies channel attention to highlight more relevant features and spatial attention to focus on more important regions. Max pooling layers operably link adjacent pairs of CBAM blocks. The output of the final CBAM block is passed to two terminal fully connected layers to generate a diagnosis. This classification system can be used to perform efficient diagnosis of hepatocellular carcinoma using solely non-contrast CT images, with diagnostic performance comparable to that of a radiologist using the current LIRADS system.Type: ApplicationFiled: September 21, 2023Publication date: May 9, 2024Inventors: Chengzhi Peng, Leung Ho Philip Yu, Wan Hang Keith Chiu, Xianhua Mao, Man Fung Yuen, Wai Kay Walter Seto

Patent number: 10115843Abstract: The present disclosure generally relates to broadband antireflective coatings for reducing reflection of light in the infrared without compromising visible light reflectance in multijunction solar cells bonded to coverglass, and methods of forming the same. The antireflective coatings include a high index, one or more intermediate index, and low index of refraction dielectric layers. The high index dielectric layer utilizes an ion beam assisted deposition to maximize the density and index of refraction. The intermediate index layer(s) increase the bandwidth of the antireflection coating, thereby improving the performance of the antireflective coating in the infrared spectrum.Type: GrantFiled: July 29, 2016Date of Patent: October 30, 2018Assignee: THE BOEING COMPANYInventors: Philip Chiu, Peter Hebert, Dhananjay Bhusari

Patent number: 10111722Abstract: The present invention discloses a task specific robot for the procedure of endoscopic submucosal dissection (ESD). This robot has two arms with nine degrees of freedom (DOF), and the capability of tissue elevation and dissection. An optimal design of these robot arms requires the use of shape memory alloy (SMA) wire and steel wire actuators to develop an improved actuation mechanism, which enables force to be transmitted to the distal tip of the robot arms for an efficient tissue elevation and dissection.Type: GrantFiled: October 30, 2015Date of Patent: October 30, 2018Assignee: THE CHINESE UNIVERSITY OF HONG KONGInventors: Chung Yan Carmen Poon, Wai Yan Philip Chiu, Yeung Yam, Yun Wong James Lau, Ka Chun Lau

Patent number: 9018020Abstract: Provided are methods and systems for treating shunts on solar cell substrates. Also provided are solar cells including such substrates. A shunt detected on a substrate proximate to a metallized grid pattern is electrically disconnected from at least the bus portion of the grid, which reduces shunt's impact on performance on the solar cell. An antireflective layer may be disposed between the shunt and a portion of the grid extending over the shunt. The exposure pattern of a photoresist used to form the antireflective layer may be adjusted accordingly to achieve this result. In some embodiments, the metallized grid may be modified by adjusting the exposure pattern of a photoresist used to form this grid. The grid may be modified to avoid any contact between the grid and the shunt or to disconnect a portion of the grid contacting the shunt from the bus portion area of the grid.Type: GrantFiled: May 24, 2013Date of Patent: April 28, 2015Assignee: The Boeing CompanyInventors: Philip Chiu, Shoghig Mesropian, Dimitri D.
