Abstract: The nonlinearity of power amplifiers (PAs) has been a severe constraint in performance of modern wireless transceivers. This problem is even more challenging for the fifth generation (5G) cellular system since 5G signals have extremely high peak to average power ratio. Nonlinear equalizers that exploit both deep neural networks (DNNs) and Volterra series models are provided to mitigate PA nonlinear distortions. The DNN equalizer architecture consists of multiple convolutional layers. The input features are designed according to the Volterra series model of nonlinear PAs. This enables the DNN equalizer to effectively mitigate nonlinear PA distortions while avoiding over-fitting under limited training data. The non-linear equalizers demonstrate superior performance over conventional nonlinear equalization approaches.

Abstract: Within metadata of a mounted file system with a file system transaction logging capability, a set of inodes is identified, each inode in the set of inodes comprising a data structure identifying a file system storage location of a portion of a file stored in the file system. A set of unused inodes is excluded from the set of inodes. A set of changing inodes is excluded from the set of inodes, each inode in the set of changing inodes comprising a flag indicating an in-progress write operation. A consistency check is performed on the metadata of the file system excluding the set of unused inodes and the set of changing inodes, the consistency check attempting to identify an inconsistency in the metadata. Responsive to the consistency check identifying an inconsistency in the metadata, the file system is remediated.

Abstract: A robot actor, or character mobility hardware platform, adapted to unleash or provide a wide variety of characters in the physical world. The robot actor enables the often screen-constrained characters to become life-like, interactive participants with nearby people in ways not presently achievable. The robot actor is an untethered, free-roaming robot that is has two (or more) legs, is adapted for high dexterity, is controlled and designed to be self-balancing, and, due to this combination of characteristics, the robot can provide characters with an illusion of life and, in many cases, in correct proportion and scale. The hardware and software of the robot actor will become a new generation of animatronic figures by providing a hardware platform capable of continuously evolving to become more capable through advances in controls and artificial intelligence (AI).

Abstract: A transmitter for measuring a process pressure includes a pressure sensor and a temperature sensor providing an input temperature signal. A first remote pressure sensitive diaphragm couples to the transmitter by a first capillary tube filled with a fill fluid having a density as a function of fill fluid temperature. An input circuit is operably connected to at least the pressure sensor and provides an intermediate pressure signal at least roughly representative of the process pressure. A correcting circuit is coupled to the temperature sensor and to the input circuit. The correcting circuit processes the intermediate pressure signal by compensating for the fill fluid density as a function of the temperature and provides a compensated output more closely representative of the process pressure. The correction circuit further performs an initial height determination based upon a pressure measurement made while no pressure is applied to the first diaphragm.
