Patent number: 11275642Abstract: The technology disclosed relates to building ensemble analytic rules for reusable operators and tuning an operations monitoring system. In particular, it relates to analyzing a metric stream by applying an ensemble analytical rule. After analysis of the metric stream by applying the ensemble analytical rule, quantized results are fed back for expert analysis. Then, one or more type I or type II errors are identified in the quantized results, and one or more of the parameters of the operators are automatically adjusted to correct the identified errors. The metric stream is further analyzed by applying the ensemble analytical rule with the automatically adjusted parameters.Type: GrantFiled: June 23, 2020Date of Patent: March 15, 2022Assignee: Lightbend, Inc.Inventors: Amit Sasturkar, Arun Kejariwal, Uday K. Chettiar, Vishal Surana, Omer Emre Velipasaoglu, Dhruv Hemchand Jain, Mohamed A. Abdelhafez

Patent number: 10404524Abstract: The technology disclosed relates to differential analysis of sets of time series pairs. In particular, it relates to building estimators of magnitude of difference between two time series. After the basic estimators are built, they are combined into ensemble estimators using linear or nonlinear prediction models to improve their accuracy. In one application, the ensemble is used for estimating the magnitudes of difference over sets of metric pairs observed from distributed applications and systems running over a computer network. The metric pairs are then ranked in decreasing order of magnitude of difference to guide an operator in prioritizing his root cause analysis of faults, thereby reducing the time-to-resolution of problems.Type: GrantFiled: December 13, 2017Date of Patent: September 3, 2019Assignee: Lightbend, Inc.Inventors: Omer Emre Velipasaoglu, Arun Kejariwal, Alan Honkwan Ngai, Craig David Upson, Uday K.

Patent number: 8488247Abstract: An object is disposed such that the apparatus is between the object and an observer. The appearance of the object is altered and, in the limit, the object cannot be observed, and the background appears unobstructed. The apparatus is formed of a metamaterial where the properties of the metamaterial are varied as a function of distance from the interfaces. The metamaterial may be fabricated as a composite material having a dielectric component and inclusions of particles of sub-wavelength size, and may also include a gain medium.Type: GrantFiled: October 5, 2009Date of Patent: July 16, 2013Assignee: Purdue Research FoundationInventors: Wenshan Cai, Vladimir M.

The appearance of the object is altered and, in the limit, the object cannot be observed, and the background appears unobstructed. The cloak is formed of a metamaterial where the properties of the metamaterial are varied as a function of distance from the cloak interfaces, and the permittivity is less than unity.
