Publication number: 20190094146Abstract: A micro-colorimetric sensor for sensing target chemicals that converts time sequence information into a spatial distribution of color. By tracking the spatial color distribution, chemical exposure over time is thus detected, which overcomes the limitation of traditional colorimetric sensors. A porous media is coated on a top surface of the substrate. Multiple sensing chemicals are fused in parallel linear channels into the porous media coating. A plate is affixed over the substrate top surface to cover the plurality of parallel linear channels. An air sample is diffused along the porous media to get a clear pattern of spatial color distribution and color images are captured. Optical parameters like gradient of spatial color distribution, intensity, and absorbance, etc., can be tracked to calculate analytes concentrations.Type: ApplicationFiled: September 26, 2018Publication date: March 28, 2019Applicant: Arizona Board of Regents on behalf of Arizona Stat e UniversityInventors: Nongjian Tao, Di Wang, Chenwen Lin

Patent number: 10199669Abstract: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.Type: GrantFiled: May 1, 2016Date of Patent: February 5, 2019Assignee: Micrsoft Technology Licensing, LLCInventors: Di Wang, Sriram Govindan, John J.

Patent number: 10078455Abstract: Aspects extend to methods, systems, and computer program products for predicting solid state drive reliability. Aspects of the invention can be used to predict and/or to configure a data center to minimize one or more of: SSD capacity degradation (how much storage an SSD has left), SSD performance degradation (reduced read/write latency/throughput), and SSD failure. Models and data center considerations can be based on device level SSD related operations, such as, for example, read, write, erase. Operations decisions can be made for a data center based on SSD specific features, such as, for example, remaining capacity, write amplification factor, etc. Dependence and/or causality of various different data center factors can be leveraged. The impact of the various data center factors on different SSD failure modes and capacity/performance degradation can be quantified to drive SSD design, SSD provisioning, and SSD operations.Type: GrantFiled: January 20, 2016Date of Patent: September 18, 2018Inventors: Iyswarya Narayanan, Di Wang, Myeongjae Jeon, Bikash Sharma, Laura Marie Caulfield, Sriram Govindan, Benjamin Franklin Cutler, Christopher W.

Publication number: 20180189288Abstract: Methods, systems, and programs are provided for presenting professional content in a user feed. The user feed is populated with industry-wise content, using relevance-driven technologies to select the best relevant industry content, while solving the problem of low-content availability for users with few connections. Professional posts created by users in a social network are identified, where each user is associated with an industry as configured in a profile of the user. A score for each identified professional post is calculated and the professional posts are sorted based on their scores. After detecting a request for data to present in a first user feed to a first user that is associated with a first industry, the server selects professional posts based on the industry of the user that created each post. The selected professional posts are then merged with other types of content and presented in the first user feed.Type: ApplicationFiled: August 1, 2016Publication date: July 5, 2018Inventors: Liang Zhang, Lin Zhu, Di Wang, Sheng Zhao, Yang Liu, Shu Chen

Publication number: 20180181640Abstract: This invention relates to methods and systems for searching. It is particularly applicable to methods of searching which enable efficient identification of compatible portfolios. Embodiments of the invention propose methods of searching which address the huge search space issue associated with identifying compatible portfolios. In particular, embodiments of the invention start their search operations simultaneously from both sides by both trying to form valid portfolios from candidate products until a valid solution is found and trying to find conflicts from the defined compatibility rules until a conflict is found which leads to the conclusion that no valid solution exists. A conclusion from either process will stop the whole searching process which can significantly reduce blind and unnecessary searching in the whole search space.Type: ApplicationFiled: December 28, 2016Publication date: June 28, 2018Inventors: Di Wang, Ivan Boyd, Ahmad Al-Rubaie, Jason Ng
