Patent number: 10499197Abstract: It may be determined that each of a first plurality of devices was stationary at a location based on received first location information. Next, a first estimated ground truth may be determined for each of the first plurality of devices at the location based on the first location information corresponding to each of the respective first plurality of devices at the location. A first plurality of location estimation errors may then be determined for each of the first plurality of devices at the location respectively based on the first location information corresponding to each of the respective first plurality of devices at the location and the first estimated ground truth for each of the respective first plurality of devices at the location. Next, each of the determined first plurality of location estimation errors for each of the first plurality of devices at the location may be aggregated to provide a first location accuracy measurement for the location.Type: GrantFiled: November 6, 2018Date of Patent: December 3, 2019Assignee: Cisco Technology, Inc.Inventors: Abhishek Mukherji, Huy Phuong Tran, Rong Peng, Santosh Ghanshyam Pandey

Patent number: 10349216Abstract: An enterprise system configures access point devices at an enterprise location to communicate with a location determination system. The location determination system receives wireless signal attributes of user computing devices broadcasting Wi-Fi signal data at the enterprise location from one or more access point devices. For a particular time window, the location determination system determines aggregated features of received wireless signal data across all access point devices, and classifies each of the user computing devices as moving or stationary by applying the wireless signal data to a model. For each of the user computing devices determined to be moving, the location determination system calculates a respective position of the user computing device based on the wireless signal data. For each of the user computing devices determined to be stationary, the location determination system does not calculate a respective position of the respective user computing device.Type: GrantFiled: August 14, 2018Date of Patent: July 9, 2019Assignee: CISCO TECHNOLOGY, INC.Inventors: Huy Phuong Tran, Abhishek Mukherji, Rong Peng, Oscar Berjarano Chavez, Santosh Ghanshyam Pandey

Patent number: 9834792Abstract: Multi-stage, biological processes and systems for converting a C1 carbon source to desired end products are described. The processes comprise dividing a gaseous C1-containing substrate, in parallel, among multiple bioreactor stages. Liquid products are successively fed, in series, from a first bioreactor stage to downstream bioreactor stages. Operation can be simplified by avoiding the requirement for microorganism separation and recycle at each stage. In addition, overall vapor-liquid mass transfer for the combined stages is very favorable, leading to high end product productivity with comparably low byproduct metabolite productivity.Type: GrantFiled: October 22, 2015Date of Patent: December 5, 2017Assignee: LANZATECH NEW ZEALAND LIMITEDInventors: Simon Richard Trevethick, Jason Carl Bromley, Guy William Waters, Michael Koepke, Loan Phuong Tran, Rasmus Jensen Overgaard

Patent number: 9648464Abstract: An efficient process is provided that exploits features in historical and current client location data to forecast client counts of different zones up to several hours ahead. These features may be obtained from correlations of client counts of multiple zones in a recent and long period of time. These features may also be combined using techniques that choose the best performing method for a particular dataset and a particular lookahead time. This process provides better forecast/prediction on the zone-based client count data, and is very useful in customer analytics which can now show the future predicted value. This can help the analytics customers to plan their operations based on the location analytics.Type: GrantFiled: May 10, 2016Date of Patent: May 9, 2017Assignee: Cisco Technology, Inc.Inventors: Huy Phuong Tran, Santosh Ghanshyam Pandey, Abhishek Bhattacharyya, Preethi Natarajan

Patent number: 8913269Abstract: A method for print portable document format (PDF) files with corrupted pages, comprising the steps of rasterizing images of non-corrupt pages but not corrupted pages of a PDF file, printing only non-corrupt pages of the PDF file, gathering and recording file and page information including which pages are non-corrupt pages and which pages are corrupted pages in the PDF file, allowing correction of the corrupted pages of the PDF file for reprint, retrieving saved file and page information for reprint of the PDF file. Based on the file and page information retrieved and print options and merge mode selected, the reprint process proceeds with rasterizing images of the corrected corrupted pages, and printing the corrected corrupted pages while merging with the already-printed non-corrupt pages to produce a complete set of print out of all non-corrupt pages and corrected corrupted pages of the PDF file in a correct sequence according to the file and page information retrieved.Type: GrantFiled: September 28, 2012Date of Patent: December 16, 2014Assignee: Konica Minolta Laboratory U.S.A., Inc.Inventors: Katsuyuki Taima, John Phuong Tran
