A technology is described for determining an intended movement from neuromuscular signals. An example method () includes receiving electromyography (EMG) data corresponding to single-ended channels of an electrode array (), where EMG signals are detected by electrodes comprising the single-ended channels of the electrode array and the EMG signals are converted to the EMG data. Determining differential channel pairs for the single-ended channels of the electrode array () and extracting feature data from the EMG data of the differential channel pairs (). Thereafter a feature data set is selected from the feature data of the differential channel pairs () and the feature data set is input to a decode model configured to correlate the feature data set to an intended movement (). Decode output is received from the decode model indicating the intended movement () and the decode output is provided to a device ().

Signal processing for decoding intended movements from electromyographic signals

A technology is described for an electronic peripheral nerve stimulation system. The electronic nerve stimulation system can include a stimulation device and an electrode array. The stimulation device can be operable to generate a high-frequency alternating current. The electrode array can be operable to apply the high-frequency alternating current received from the stimulation device to selected subpopulations of peripheral nerve fibers within a peripheral nerve to block transmission of neural signals along the selected subpopulations of peripheral nerve fibers within the peripheral nerve.

A technology is described for an electronic nerve stimulation system. The electronic nerve stimulation system can include a stimulation device operable to generate a high-frequency alternating current. The electronic nerve stimulation system can include one or more wearable electrodes operable to apply the high-frequency alternating current from the stimulation device to peripheral nerves to provide an electrical stimulation of neuronal tissue to treat pain. The one or more wearable electrodes can interface with the stimulation device via a connection system.

A breast pump device for pumping breast milk is disclosed. The breast pump device may include a breast shield for receiving a breast, a collection container for receiving breast milk, a tubing connecting the breast shield to the collection container, and a pump connected to the collection container, configured to draw breast milk from the breast shield, through the tubing, and into the collection container. The breast shield may include a channel extending from an interior portion of the breast shield located near a nipple of the breast to an exterior portion of the breast shield. The various components of the breast pump device may be made out of antimicrobial materials. One or more sensors and/or computing devices may be incorporated to measure the amount of milk produced, monitor temperature of the milk, and provide alerts regarding pumping schedules.
