Patent number: 10876803Abstract: Systems according to the present disclosure provide one or more surfaces that function as heat or power radiating surfaces for which at least a portion of the radiating surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges.Type: GrantFiled: September 17, 2019Date of Patent: December 29, 2020Assignee: Fractal Antenna Systems, Inc.Inventor: Nathan Cohen

Patent number: 10877937Abstract: Techniques for monitoring local and/or remote file systems by a synchronization component (e.g., client/server) of a cloud-based platform are disclosed. In some embodiments, a method of building synchronization events by a synchronization component (e.g., a synchronization server/client) includes obtaining a set of items that have been changed and their new states and retrieving last known states of the set of items that are stored in a reference snapshot inside a filesystem scanner. The method further includes generating differences between the new states and the last known states of the set of items as item changes and utilizing information provided by the item changes to translate the item changes into synchronization events for execution on the opposing file system. A method of handling failed synchronization events by a synchronization component of the cloud-based platform by collapsing a subsequent event with the failed synchronization event is also disclosed.Type: GrantFiled: April 20, 2017Date of Patent: December 29, 2020Assignee: Box, Inc.Inventors: Benjamin Campbell Smith, David Mackenzie, Yiming Lu, Kunal Parmar, Peter Potrebic

Patent number: 10873390Abstract: A novel system and apparatus for detecting and locating an external aggression on at least one optical cable of an optical communication system is provided. For example, a signal from a transmitter may be received and analysis may be performed to recover a state-of-polarization (SOP) associated with the signal. A first rapid polarization change that occurs may be identified, which may indicate that an external aggression has occurred on the at least one optical cable. A time offset between the first rapid polarization change and a second rapid polarization change may be used to estimate a location of the external aggression.Type: GrantFiled: June 6, 2019Date of Patent: December 22, 2020Assignee: SubCom, LLCInventor: Neal S.

Patent number: 10848188Abstract: A vehicle including an antenna that receives a first signal and a second signal having different operating frequency bands is provided. An amplifying part of the antenna includes a first amplifier configured to amplify the first signal and a second amplifier configured to amplify the second signal. A receiving part includes a first tuner configured to tune the first signal amplified by the amplifying part and a second tuner configured to tune the second signal amplified by the amplifying part. A first switch connects the antenna to the first amplifier or the second amplifier, a second switch connects the amplifying part to the first tuner or the second tuner, an input part receives a channel from a user, and a controller individually operates the first switch and the second switch based on an operating frequency band of the received channel.Type: GrantFiled: December 3, 2019Date of Patent: November 24, 2020Assignees: Hyundai Motor Company, Kia Motors CorporationInventor: Sang Heun Lee

Patent number: 10812026Abstract: Envelope tracking can be employed to reduce power consumption of a power amplifier, but envelope tracking can introduce nonlinearities to a power amplifier. These nonlinearities can manifest themselves as noise at the output of the power amplifier. Embodiments described herein provide techniques for characterizing a parameter indicative of power amplifier noise when envelope tracking is employed. Measurement of this parameter can permit power amplifier designers to decide whether to forgo envelope tracking if a power amplifier is too susceptible to such noise, redesign the power amplifier to improve compatibility with envelope tracking, or to employ distortion compensation circuitry to reduce the noise output by the power amplifier. Counterintuitively, this distortion compensation circuitry may involve increasing the power, such as the envelope tracking power supply. However, increasing the power may be a desirable trade-off for increased linearity.Type: GrantFiled: June 24, 2019Date of Patent: October 20, 2020Assignee: Skyworks Solutions, Inc.Inventors: Yu Zhu, Oleksiy Klimashov, Dylan C.

Patent number: 10762794Abstract: Methods and systems are provided for operating a vehicle that supports an automated action, such as an aircraft supporting autopilot, autothrottle, and various other autonomous operations and operating modes. One exemplary method of operating a vehicle involves obtaining one or more user inputs pertaining to an automated action to be performed by an onboard system, obtaining current vehicle status information, determining an operational objective for the automated action based at least in part on the current status information and the one or more user inputs, and providing guidance information pertaining to the automated action in a manner that is influenced by the operational objective and the current status information. For example, the guidance information may include indication of a remedial action to resolve a discrepancy between the operational objective and a projected aircraft behavior in the context of the operational objective or the current vehicle status.Type: GrantFiled: September 19, 2016Date of Patent: September 1, 2020Assignee: HONEYWELL INTERNATIONAL INC.Inventor: Stephen Whitlow

Patent number: 10749557Abstract: A system and method for adaptive spurious signal (spur) processing at a broadband RF receiver. Spur processing addresses the detection of spurs generated by the receiver when high level RF signals are present at its input. The spurs can lead to undesired false detections. Based on signal parameters of the received RF signal, the system detects a strong enough real signal that would cause a spur and prevent generation of false reports. The adaptive spur mitigation scheme uses multiple detection and report thresholds to enable false report rejection with an improved high probability of rejecting false detections, while minimizing the adverse effects on multi-tone dynamic range. The necessary detection and report thresholds are generated based on a system level behavioral model that predicts the performance of several different types of spurs as a function of signal parameters. The thresholds are tuned to match the behavior of the dominant spur.Type: GrantFiled: July 12, 2019Date of Patent: August 18, 2020Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Gregory T.
