Abstract: A method for generating an EEG signal is disclosed. Multiple signals from multiple electrodes applied to a user's scalp are measured. The signals correspond to electrical activity generated by the user's brain. Each of the signals is evaluated using a machine learning algorithm in real-time to determine a quality of each of the signals. One or more of the signals is selected based on quality in real-time to provide one or more selected signals. An EEG signal is outputted corresponding to the electrical activity based on the selected signals.

Abstract: Example implementations relate to a solar panel system including solar cells and an inverter configured to receive electrical energy generated by solar cells and to convert the electrical energy to an electrical signal having an oscillation frequency. The system also include a transmit resonator coupled to the inverter and configured to resonate at the oscillation frequency. Moreover, the transmit resonator may be coupled via a wireless resonant coupling link to a receive resonator that is also configured to resonate at the oscillation frequency. Further, the system may also include a controller configured to determine for the system a mode of operation from among the following modes: (i) a common mode, (ii) a differential mode, and (iii) an inductive mode. And the controller is then configured to instruct the transmit resonator to provide via the wireless resonant coupling link electrical power according to the determined mode of operation.

Abstract: Systems and methods for designing a hybrid neural network comprising at least one physical neural network component and at least one digital neural network component. A loss function is defined within a design space composed of a plurality of voxels, the design space encompassing one or more physical structures of the at least one physical neural network component and one or more architectural features of the digital neural network. Values are determined for at least one functional parameter for the one or more physical structures, and the at least one architectural parameter for the one or more architectural features, using a domain solver to solve Maxwell's equations so that a loss determined according to the loss function is within a threshold loss. Final structures are defined for the at least one physical neural network component and the digital neural network component based on the values.
