Patent number: 10592440Abstract: Systems and methods for adding a logic layer between FPGA I/O and the core logic of the FPGA. With the extra layer, users can monitor and/or modify the I/O to the FPGA. In addition, users can monitor and/or modify input/output to the core logics of the FPGA, thereby filtering both I/O to the FPGA and the logic blocks of the FPGA. With the filtering in place, a non-intrusive digital scope can be implemented which can, in turn, be used to create a “black box” regarding FPGA I/O during the occurrence of the catastrophic events within the system.Type: GrantFiled: February 21, 2019Date of Patent: March 17, 2020Assignee: Oracle International CorporationInventors: Xianda Ma, Michael David Derbish, Cornelia Luise Edeltraut Koch-Stoschek, Rambabu Lolabattu, Simon yiu hoi Poon, Cheng Yang

Publication number: 20180096587Abstract: A server receives signals indicating an alert condition for a location that is defined by a set of location attributes and identifies one or more base stations that serve one or more cells that overlap with the location, which encompasses less than all of the cells. The server transmits a message to the one or more base stations identifying the alert condition and including the set of location attributes. A user equipment receives the message identifying the alert condition and including the set of location attributes that define the location of the alert condition. The user equipment compares a location of the user equipment to the set of location attributes and generates an alert in response to the location of the user equipment being within the location of the alert condition.Type: ApplicationFiled: October 5, 2016Publication date: April 5, 2018Inventors: Bilgehan Erman, Qi Liao, Lawrence O'Gorman, Simon Yiu

Patent number: 9584969Abstract: Systems and methods for a localization system are provided. In one aspect, a RF signature map for a geographical area is determined using a Gaussian Process (“GP”) model. Training RF measurements are taken at some locations within the area to train the GP using the Firefly Algorithm (“FA”). The RF measurements for other locations of the area are predicted using the conditional probabilities of the trained GP and without taking RF measurements at those other locations. The RF signature map is used for fingerprinting localization. In one aspect, a reference RF signature map is constructed for one, some, or all access points (“APs”) covering the area. A location of a user device, such as, for example, a smart phone, is then estimated by comparing the RF signals received by the user device from one or more APs with the determined one or more reference RF signature maps using a combined likelihood function.Type: GrantFiled: December 23, 2014Date of Patent: February 28, 2017Assignee: Alcatel-Lucent USA Inc.Inventors: Simon Yiu, Kai Yang

Publication number: 20160127911Abstract: In certain embodiments, a cellular wireless communications network has clusters, each cluster having a plurality of cells and a cluster-level controller that dynamically divides the cluster into non-interfering sub-clusters for each resource allocation unit (e.g., physical resource block) . Each sub-cluster has one or more cells that transmit to a single user in the cluster for the resource allocation unit, and at least one sub-cluster has at least two cells that transmit to a single user for the resource allocation unit using a distributed diversity mode of communication in which the at least two cells transmit the same data to the single user. The controller divides the cluster into sub-clusters based on determinations of whether users in the cluster are susceptible to interference from non-serving cells in the cluster. By assigning potentially interfering, non-serving cells to the sub-cluster for a user, those non-serving cells are eliminated as sources of interference.Type: ApplicationFiled: November 4, 2014Publication date: May 5, 2016Inventors: Simon Yiu, Doru Calin

Publication number: 20130331136Abstract: Various methods and devices are provided to improve wireless communications. In one method, a need for additional wireless service in a target area is detected (401). As part of a first-layer beamforming process, a signaling beam is directed (402) toward the target area. As part of a second-layer beamforming process, at least some inter-cell interference is canceled (403) in the target area.
