Publication number: 20230099734Abstract: An ultrasonic imaging configuration rendering an image based on a reflected beam aligned with a needle insertion axis provides enhanced images and guidance. A percutaneous insertion guidance device for ultrasonic (US) imaging includes an US transducer and a reflector for redirecting imaging signals between the transducer and an imaged region. An enclosure or bracket is adapted to support the reflector at a predetermined angle based on a surgical target in the imaged region such that a forward beam direction from the transducer reflects in a direction of the needle insertion as the needle passes through a discontinuity or slot in the reflector. The resulting return signal is based on an axial alignment of the US signals with the needle travel towards the surgical target.Type: ApplicationFiled: November 28, 2022Publication date: March 30, 2023Inventors: Haichong Zhang, Ryosuke Tsumura, Yichuan Tang

Patent number: 10963785Abstract: Methods, systems and apparatus that provide for perceptual, cognitive, and motor behaviors in an integrated system implemented using neural architectures. Components of the system communicate using artificial neurons that implement neural networks. The connections between these networks form representations—referred to as semantic pointers—which model the various firing patterns of biological neural network connections. Semantic pointers can be thought of as elements of a neural vector space, and can implement a form of abstraction level filtering or compression, in which high-dimensional structures can be abstracted one or more times thereby reducing the number of dimensions needed to represent a particular structure.Type: GrantFiled: January 11, 2018Date of Patent: March 30, 2021Assignee: Applied Brain Research Inc.Inventors: Christopher David Eliasmith, Terrence Charles Stewart, Feng-Xuan Choo, Trevor William Bekolay, Travis Crncich-DeWolf, Yichuan Tang, Daniel Halden Rasmussen

Patent number: 10943148Abstract: A system employs an inspection neural network (INN) to inspect data generated during an inference process of a primary neural network (PNN) to generate an indication of reliability for an output generated by the PNN. The system includes a sensor configured to capture sensor data. Sensor data captured by the sensor is provided to a data analyzer to generate an output using the PNN. An analyzer inspector is configured to capture inspection data associated with the generation of the output by the data analyzer, and use the INN to generate an indication of reliability for the PNN's output based on the inspection data. The INN is trained using a set of training data that is distinct from the training data used to train the PNN.Type: GrantFiled: November 30, 2017Date of Patent: March 9, 2021Assignee: Apple Inc.Inventors: Rui Hu, Ruslan Salakhutdinov, Nitish Srivastava, YiChuan Tang

Publication number: 20180157972Abstract: A system includes a neural network organized into layers corresponding to stages of inferences. The neural network includes a common portion, a first portion, and a second portion. The first portion includes a first set of layers dedicated to performing a first inference task on an input data. The second portion includes a second set of layers dedicated to performing a second inference task on the same input data. The common portion includes a third set of layers, which may include an input layer to the neural network, that are used in the performance of both the first and second inference tasks. The system may receive an input data and perform both inference tasks on the input data in a single pass. During training, a training sample with annotations for both inference tasks may be used to train the neural network in a single pass.Type: ApplicationFiled: November 30, 2017Publication date: June 7, 2018Applicant: Apple Inc.Inventors: Rui Hu, Kshitiz Garg, Hanlin Goh, Ruslan Salakhutdinov, Nitish Srivastava, YiChuan Tang

Patent number: 7840071Abstract: A method of identifying regions of different content in an image comprises dividing image data into a plurality of pixel blocks, extracting features of the pixel blocks and classifying the content of the pixel blocks based on extracted features. Extracting comprises, for each pixel block, convolving a magic square filter with the pixels of the pixel block and summing the results, and calculating the percentage of background pixels in the pixel block. The magic square filter is a 3×3 kernel that has a specific selectivity towards the statistical appearance and geometric alignment of a document based text of various fonts, sizes and styles. The complete sum of the magic square filter, as well as the sum of the rows, columns and diagonals of the magic square filter are zero.Type: GrantFiled: December 12, 2006Date of Patent: November 23, 2010Assignee: Seiko Epson CorporationInventors: Yichuan Tang, Hui Zhou
