Abstract: In an approach to neural interface systems, a system includes feature extraction circuitry to identify one or more features of one or more input signals; and neural processing circuitry. The neural processing circuitry is configured to: identify a first context of a plurality of contexts based on a first trigger event; decode the one or more features of the one or more input signals to determine a first task of a plurality of tasks in the first context; and responsive to detecting a second trigger event, change the first context to a second context of the plurality of contexts.

Abstract: At least one electrical brain signal is received from a patient and is demultiplexed into an efferent motor intention signal and at least one afferent sensory signal (such as an afferent touch sense signal and/or an afferent proprioception signal). A functional electrical stimulation (FES) device is controlled to apply FES to control a paralyzed portion of the patient that is paralyzed due to a spinal cord injury of the patient. The controlling of the FES device is based on at least the efferent motor intention signal. A demultiplexed afferent touch sense signal may be used to control a haptic device. The afferent sensory signal(s) may be used to adjust the FES control.

Abstract: The present disclosure relates generally to metrics used to detect or indicate a state of impairment in a test subject due to use of drugs or alcohol, and more particularly to metrics used in connection with a virtual-reality (“VR”) environment that implements drug and alcohol impairment tests, where the metrics are used to detect or indicate impairment.

Abstract: A non-invasive control system for neuromuscular stimulation includes an eye-tracking device, an electrical stimulation device, and software that interprets the eye movements of the user to determine an intended movement and sends electrical signal(s) to the stimulation device to achieve the intended movement. For example, the stimulation device may be a sleeve with electrodes worn on a paralyzed limb, with the intended movement being the movement of the limb.

Abstract: A brain-computer interface (BCI) includes a multichannel stimulator and a decoder. The multichannel stimulator is operatively connected to deliver stimulation pulses to a functional electrical stimulation (FES) device to control delivery of FES to an anatomical region. The decoder is operatively connected to receive at least one neural signal from at least one electrode operatively connected with a motor cortex. The decoder controls the multichannel stimulator based on the received at least one neural signal. The decoder comprises a computer programmed to process the received at least one neural signal using a deep neural network. The decoder may include a long short-term memory (LSTM) layer outputting to a convolutional layer in turn outputting to at least one fully connected neural network layer. The decoder may be updated by unsupervised updating. The decoder may be extended to include additional functions by transfer learning.

Abstract: The present disclosure relates generally to systems, methods, and devices for interpreting neural signals to determine a desired movement of a target, transmitting electrical signals to the target, and dynamically monitoring subsequent neural signals or movement of the target to change the signal being delivered if necessary, so that the desired movement is achieved. In particular, the neural signals are decoded using a feature extractor, decoder(s) and a body state observer to determine the electrical signals that should be sent.

Abstract: A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.

Abstract: Methods of determining the source of an unknown sample are disclosed. Mass spectra from possible sources are obtained using two-dimensional gas chromatography coupled with time-of-flight mass spectrometry. That data is processed to obtain a dataset. A random forest algorithm is used to classify the dataset and create a classifier that distinguishes between the possible sources.
