Patent number: 11977550Abstract: Generating a synthetic longitudinal dataset includes identifying subsequence patterns in records defining event sequences for patients. Feature vectors are determined, each characterizing a corresponding one of the records, based on the subsequence patterns. The feature vectors are embedded in a lower dimension space. A seed record is iteratively selected from among the records and in each iteration: subsequence patterns are identified in a subset of the records. Instances of subsequence patterns in the seed record are replaced with instances of similar subsequence patterns identified in the subset of the records to form a modified seed record. The iterations are repeated until all of the records have been selected as the seed record. The modified seed records are combined to form the synthetic dataset.Type: GrantFiled: April 12, 2023Date of Patent: May 7, 2024Assignee: MEDIDATA SOLUTIONS, INC.Inventors: Jacob Aptekar, Mandis S. Beigi, Pierre-Louis Bourlon, Jason Mezey, Afrah Shafquat, Jimeng Sun

Publication number: 20240091696Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.Type: ApplicationFiled: August 30, 2023Publication date: March 21, 2024Inventors: Kristof DECOSTER, Johnny CRAESSAERTS, Johan G.

Patent number: 11935634Abstract: A system for predicting and summarizing medical events from electronic health records includes a computer memory storing aggregated electronic health records from a multitude of patients of diverse age, health conditions, and demographics including medications, laboratory values, diagnoses, vital signs, and medical notes. The aggregated electronic health records are converted into a single standardized data structure format and ordered arrangement per patient, e.g., into a chronological order. A computer (or computer system) executes one or more deep learning models trained on the aggregated health records to predict one or more future clinical events and summarize pertinent past medical events related to the predicted events on an input electronic health record of a patient having the standardized data structure format and ordered into a chronological order.Type: GrantFiled: August 30, 2017Date of Patent: March 19, 2024Assignee: Google LLCInventors: Alexander Mossin, Alvin Rajkomar, Eyal Oren, James Wilson, James Wexler, Patrik Sundberg, Andrew Dai, Yingwei Cui, Gregory Corrado, Hector Yee, Jacob Marcus, Jeffrey Dean, Benjamin Irvine, Kai Chen, Kun Zhang, Michaela Hardt, Xiaomi Sun, Nissan Hajaj, Peter Junteng Liu, Quoc Le, Xiaobing Liu, Yi Zhang

Patent number: 8137572Abstract: A method of making a planar lightwave circuit (PLC) waveguide capable of being integrated with a surface-mounted component is presented. The method entails etching a silicon substrate to form a slanted wall, forming a nonreflective waveguide portion on the silicon substrate, and depositing a reflective layer on the slanted wall. Light travels through the nonreflective waveguide portion in substantially a first direction, and the light from the nonreflective waveguide portion strikes the reflective layer to be redirected in a second direction. The second direction may be the direction toward the surface-mounted component. A PLC waveguide device made with the above method is also presented.Type: GrantFiled: October 12, 2009Date of Patent: March 20, 2012Assignee: Enablence USA Components Inc.Inventors: HongZhen Wei, Ray Liang, Wenhua Lin, Ted Chen, Jacob Sun

Patent number: 7639908Abstract: The invention is a data transmission device that includes: an input Free Propagation Region (FPR) receiving a multi-wavelength signal and a single-wavelength signal, and two sets of arrayed waveguides coupled to the input FPR to carry the multi-wavelength signal and the single-wavelength signal, respectively. The arrayed waveguides demultiplex the multi-wavelength signal and create copies of the single-wavelength signal. The output plane of an output FPR receives the demultiplexed wavelengths and the copies of the single-wavelength signal such that one of the demultiplexed wavelengths and one of the copies of the single-wavelength signal focus onto the same position on the output plane. The device allows data (e.g., video stream) to be broadcast to all subscribers in a Wavelength-Division-Multiplexed Passive Optical Network (WDM-PON) architecture.Type: GrantFiled: January 23, 2008Date of Patent: December 29, 2009Assignee: Enablence USA Components, Inc.Inventors: Saurav Das, Boris Grek, Jacob Sun

Patent number: 7008551Abstract: A method for forming optical devices on-planar substrates, as well as optical devices formed by the method are described. The method uses a linear injection APCVD process to form optical waveguide devices on planar substrates. The method is performed at approximately atmospheric pressure. According to the method, a wafer with a lower cladding layer already formed by either CVD or oxidation is placed on a conveyer, which may include a heating element. The heated wafer is transported underneath a linear injector such that the chemicals from the linear injector react on the wafer surface to form a core layer. After the core layer is formed, photoresist is spun on the surface of the wafer, and then standard lithography is used to pattern the optical devices. Next, reactive ion etching (RIE) is used to form waveguide lines. The remaining photoresist is then removed. An upper cladding layer is formed to substantially cover the core regions.Type: GrantFiled: April 30, 2003Date of Patent: March 7, 2006Assignee: Andevices, Inc.Inventors: C. Jacob Sun, James K. Eu

Publication number: 20040022490Abstract: A filter module that includes a filter, such as an AWG filter, and a semiconductor optical amplifier (SOA) is described. Additionally, a method of multiplexing and/or demultiplexing optical signals using the DWDM filter module is described. The filter and SOA can be integrated together either through compact packaging (with fiber and connectors), or through on-chip integration. The SOA can fully compensate for the insertion loss due to, for example, an AWG filter or plurality of AWG filters. Additionally, the polarization dependent loss of the composite module can be reduced by adjusting the polarization dependent gain of the SOA to compensate for the polarization dependent loss of the AWG filter.Type: ApplicationFiled: July 18, 2003Publication date: February 5, 2004Inventors: James K.

Patent number: 5432877Abstract: A method and apparatus are disclosed whereby integrated optical circuits having waveguide ends of lens geometry are formed which improve the waveguide's optical coupling to light sources and detectors. A channel waveguide is formed on a substrate and the waveguide ends are shaped into lens form by etching to form a protrusion and heating the waveguide to or above the softening temperature of core material of the waveguide resulting in surface tension in the core material that functions to shape the protrusion into a substantially cone-shaped lens end having a smooth surface.Type: GrantFiled: June 3, 1994Date of Patent: July 11, 1995Assignee: Photonic Integration Research, Inc.Inventors: C.
