Patent number: 11863221Abstract: Described is a Neuromorphic Adaptive Core (NeurACore) cognitive signal processor (CSP) for wide instantaneous bandwidth denoising of noisy signals. The NeurACore CSP includes a NeurACore block, a globally learning layer, and a neural combiner. The NeurACore block is operable for receiving as an input a mixture of in-phase and quadrature (I/Q) signals and mapping the I/Q signals onto a neural network to determine complex-valued output weights of neural states of the neural network. The global learning layer is operable for adapting the complex-valued output weights to predict a most likely next value of the input I/Q signal. Further, the neural combiner is operable for combining a set of delayed neural state vectors with the weights of the global learning layer to compute an output signal, the output signal being separate in-phase and quadrature signals.Type: GrantFiled: July 14, 2021Date of Patent: January 2, 2024Assignee: HRL LABORATORIES, LLCInventors: Sanaz Adl, Peter Petre, Gabriel L.

Patent number: 11118937Abstract: Described is a system for adaptive calibration of a sensor of an inertial measurement unit. Following each sensor measurement, the system performs automatic calibration of a multi-axis sensor. A reliability of a current calibration is assessed. If the current calibration is reliable, then bias and scale factor values are updated according to the most recent sensor measurement, resulting in updated bias and scale factor values. If the current calibration is not reliable, then previous bias and scale factor values are used. The system causes automatic calibration of the multi-axis sensor using either the updated or previous bias and scale factor values.Type: GrantFiled: February 15, 2018Date of Patent: September 14, 2021Assignee: HRL Laboratories, LLCInventors: Adour V.

Patent number: 10718198Abstract: Described is a system for estimating a trajectory of a borehole. The system processes signals of sensor streams obtained from an inertial sensor system. Using the set of processed signals, the system determines whether a drill is in a survey mode state or a continuous mode state, and a measured depth of the borehole is determined.

Patent number: 10454179Abstract: Several embodiments of systems and methods are described for a compound structure consisting of a compact conformal surface-wave antenna feed structure attached to a conformal surface-wave antenna. The feed structure is an Artificial Impedance Surface (AIS) which takes as input an arbitrary source, converts it into a desired surface-wave waveform, which then feeds its output into the attached conformal surface-wave antenna for optimal radiation performance. The feed structure can be made up of several sizes and shapes of AIS metal patches and can produce plane isotropic as well as anisotropic surface-wave output. The surface-wave antenna can be a radiating hologram made up of the same AIS metallic patches as the feed structure and fabricated on the same dielectric substrate.Type: GrantFiled: August 10, 2016Date of Patent: October 22, 2019Assignee: HRL Laboratories, LLCInventors: Adour V.
