Publication number: 20230169650Abstract: A method including receiving a specimen comprising a carrier, a first target species, and a first component and storing at least a portion of the carrier and the first target species in a storage media by self-driven filtering of the specimen in the storage media, wherein the storage media comprises porous superabsorbent polymer (PSAP) beads. The PSAP beads provide for fast and self-driven microfiltration of biofluid samples. The treatment effectively separates small analytical targets (e.g., glucose, catalase, and bacteriophage) and large undesired components (e.g., bacteria and blood cells) in the biofluids by capturing the former inside and excluding the latter outside the PSAP beads. The treatment can reduce sample volume, self-aliquot the liquid sample, avoid microbial contamination, separate plasma from blood cells, stabilize target species inside the beads, and enable long-term storage at room temperature.Type: ApplicationFiled: April 29, 2021Publication date: June 1, 2023Inventors: Xing Xie, Wensi Chen

Patent number: 10618532Abstract: The present invention discloses a train coupler structural health monitoring system. The system includes one or more sensors mounted to or integrated with the train coupler, a data acquisition unit for receiving signal or data from the sensors, and a processing unit for determining the train coupler's structural health based on the received signal or data. Inspections via the system can be performed in real time continuously or periodically while a train is in service. It can also be performed offline while a train is not in service. Inspection method can be either passive, where sensors collect signals without generating excitation signals to the structure, or active, where some sensors are used as actuators to actively send excitation signals to the structure and other sensors or the actuators themselves collect the structural response signals. The data acquisition unit receives signals or data from sensors.Type: GrantFiled: November 20, 2017Date of Patent: April 14, 2020Inventors: Chang Zhang, Lei Liu, Xihong Jin, Xining Li, Xiangjian Yang, Yanjun Zeng, Yongqiang He, Xing Xie, Gang Yan

Patent number: 10571288Abstract: Techniques for providing a trajectory route to multiple geographical locations of interest are described. This disclosure describes receiving global position system (GPS) logs associated with respective individual devices, each of the GPS logs including trajectories connecting a set of geographical locations previously visited by an individual of a respective individual device. A trajectory route service receives a request for a trajectory connecting a set of geographical locations of interest specified by a user. The trajectory route service calculates a proximal similarity between (1) the set of geographical locations of interest specified by the user, and (2) respective sets of geographical locations from the GPS logs. The trajectory route service constructs the requested trajectory with use of at least one of the trajectories from the GPS logs determined at least in part according to the calculated proximal similarities.Type: GrantFiled: January 20, 2017Date of Patent: February 25, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Yu Zheng, Zaiben Chen, Xing Xie

Patent number: 9794423Abstract: Described is a technology by which a user hums, sings or otherwise plays a user-provided rendition of a ringtone (or ringback tone) through a mobile telephone to a ringtone search service (e.g., a WAP, interactive voice response or SMS-based search platform). The service matches features of the user's rendition against features of actual ringtones to determine one or more matching candidate ringtones for downloading. Features may include pitch contours (up or down), pitch intervals and durations of notes. Matching candidates may be ranked based on the determined similarity, possibly in conjunction with weighting criterion such as the popularity of the ringtone and/or the importance of the matched part. The candidate set may be augmented with other ringtones independent of the matching, such as the most popular ones downloaded by other users, ringtones from similar artists, and so forth.Type: GrantFiled: June 15, 2016Date of Patent: October 17, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Lie Lu, Yutao Xie, Xing Xie, Jiafan Ou, Ruihao Weng

Patent number: 9754226Abstract: Techniques for analyzing effectiveness of an urban area based on traffic patterns collected from route-oriented vehicles. A process collects sequences of global positioning system (GPS) points in logs and identifies geographical locations to represent the urban area where the route-oriented vehicles traveled. The process models traffic patterns by: partitioning the urban area into regions based at least in part on major roads, segmenting the GPS points from the logs into time slots, and identifying the GPS points associated with transporting a passenger in the route-oriented vehicles. The process models traffic patterns by projecting the identified GPS points onto the regions to construct transitions of the identified GPS points travelling between the regions. Then the process builds a matrix of the regions for each time slot in each day based on a number of the transitions. Each item in the matrix represents an effectiveness of a connection between two regions.Type: GrantFiled: December 13, 2011Date of Patent: September 5, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Yu Zheng, Xing Xie

Patent number: 9683858Abstract: Described is a technology by which raw GPS data is processed into segments of a trip, with a predicted mode of transportation (e.g., walking, car, bus, bicycling) determined for each segment. The determined transportation modes may be used to tag the GPS data with transportation mode information, and/or dynamically used. Segments are first characterized as walk segments or non-walk segments based on velocity and/or acceleration. Features corresponding to each of those walk segments or non-walk segments are extracted, and analyzed with an inference model to determine probabilities for the possible modes of transportation for each segment. Post-processing may be used to modify the probabilities based on transitioning considerations with respect to the transportation mode of an adjacent segment. The most probable transportation mode for each segment is selected.Type: GrantFiled: November 12, 2012Date of Patent: June 20, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Yu Zheng, Longhao Wang, Like Liu, Xing Xie

Patent number: 9536146Abstract: Techniques for detecting outliers in data and determining spatiotemporal causal interactions in the data are discussed. A process collects global positioning system (GPS) points in logs and identifies geographical locations to represent the area where the service vehicles travelled with a passenger. The process models traffic patterns by: partitioning the area into regions, segmenting the GPS points from the logs into time bins, and identifying the GPS points associated with transporting the passenger. The process projects the identified GPS points onto the regions to construct links connecting GPS points located in two or more regions. Furthermore, the process builds a three-dimensional unit cube to represent features of each link. The points farthest away from a center of data cluster are detected as outliers, which represent abnormal traffic patterns. The process constructs outlier trees to evaluate relationships of the outliers and determines the spatiotemporal causal interactions in the data.Type: GrantFiled: December 31, 2014Date of Patent: January 3, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Yu Zheng, Xing Xie

Patent number: 9509028Abstract: A microbial battery is provided. At the anode, microbial activity provides electrons to an external circuit. The cathode is a solid state composition capable of receiving the electrons from the external circuit and changing from an oxidized cathode composition to a reduced cathode composition. Thus, no external source of oxygen is needed at the cathode, unlike conventional microbial fuel cells. The cathode can be removed from the microbial battery, re-oxidized in a separate oxidation process, and then replaced in the microbial battery. This regeneration of the cathode amounts to recharging the microbial battery.Type: GrantFiled: October 2, 2013Date of Patent: November 29, 2016Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Xing Xie, Yi Cui, Craig S.
