  • Patent number: 11303432
    Abstract: Double key encryption encrypts sensitive data using a content key, obtains a user public key from a key management service, encrypts the content key using the user public key, and encrypts the result using a cloud service provider key. Data confidentiality is protected efficiently through multilevel encryption and also by utilizing keys that are managed by different entities. Sensitivity labeling allows analytics to track sensitive data without compromising confidentiality. Compliance mechanisms may use attribute-based access control to support storage of sensitive data in a cloud, but only inside a permitted region, and without giving the cloud service provider access to the sensitive data.

  • Publication number: 20220100741
    Abstract: Systems and methods are described herein for interpreting natural language search queries that account for contextual relevance of words of the search query that would ordinarily not be processed, including, for example, processing each word of the query. Each term or phrase is associated with a respective part of speech, and a frequency of occurrence of a combination of adjacent terms or phrases public domain is determined. A relevance of each term is then determined based on its respective type of term and frequency of occurrence in the public domain. The natural language search query is then interpreted based on the importance or relevance of each term.

  • Patent number: 11258395
    Abstract: A voltage comparator and a programmable counter coupled to a high-speed clock are used to provide a near constant delay time for use in a closed-loop system. The voltage comparator input-output time delay is characterized at a certain temperature and operating voltage then variances in the voltage comparator delay times over a range of operating temperatures and voltages are measured and/or extrapolated. A number of clock pulses used for a delay time count are programmed into the programmable counter to provide for a near constant delay time from a change at the input of the voltage comparator to a change at the output of the programmable counter.

  • Patent number: 11250634
    Abstract: Insertion of supplemental content into a virtual environment is automated using a machine learning model. The machine learning model is trained to calculate a confidence value that a candidate virtual object fits into a virtual environment based on an input that includes a candidate virtual object, a list of persistent virtual objects, and a list of temporary virtual objects. The machine learning model is trained using the persistent and temporary objects displayed in the current virtual environment until it predicts that a selected virtual object fits into the current virtual environment. The trained machine learning model is then used to select a virtual object comprising supplemental content to be inserted as a new virtual object in the virtual environment.

  • Publication number: 20220038928
    Abstract: A system and method for hierarchical computation of KPI(s). The method encompasses receiving for at least one time slice, counter(s) associated with each node from one or more nodes. The method further encompasses defining at each time slice, metrics for said each node based on associated counter(s). The method thereafter comprises computing a locally aggregated value and a time aggregated value of the metrics. The method further encompasses mapping, the time aggregated value of each metric to a control center hierarchy (CCH). Further the method calculates a hierarchically aggregated value for each metric present in a target list of metrics associated with KPI expression(s) corresponding to said CCH, based on an aggregation of all time aggregated values of said each metric. The method thereafter encompasses computing, by a KPI scheduler unit, the KPI(s) for said CCH based at least on said hierarchically aggregated value and said KPI expression(s).

  • Patent number: 11233870
    Abstract: A call control entity (“entity”) communicates with Internet Protocol (IP) phones. Upon receiving from an IP phone a headset connect message indicating that a headset is connected to the IP phone and including a headset identifier of the headset, the entity determines whether there is stored in a call control database a mapping between the headset identifier and a user identifier associated with a user, the mapping configured to provide access to an existing IP phone configuration profile in the call control database. If the mapping exist, the entity completes an extension mobility auto login of the user through the IP phone, which results in acquiring the user identifier from the IP phone. Responsive to completing the extension mobility auto login, the entity accesses the existing IP phone configuration profile based on the user identifier and the mapping, and configures the IP phone with the existing IP phone configuration profile.

  • Publication number: 20220021123
    Abstract: An electromagnetic energy absorber comprising a thin electrically-conductive ground plane as a base. Dielectric layers are positioned over the ground plane and high impedance surface (HIS) as a top layer. The impedance layer can be formed by loading the lumped resistor to a metallic grating like an FSS (Frequency Selective Surface). An air-spacer between the substrates has replaced the problem of the large electrical thickness of the substrate with effective permittivity. Metamaterial structures enable control over the resonant frequencies, and performance is enhanced over a broad frequency band. In addition, two broadband reflective-type linear to orthogonal polarization converters are disclosed that provide improved bandwidth and angular stability performance.
