摘要： A system for determining muscle activation comprises a set of electrode adherable to a skin of a subject, and a processor in communication with the electrodes. The processor has a circuit configured for receiving locations of the electrodes and electrical signals detected by the electrodes, analyzing the signals to identify a section of an active muscle, identifying locations of at least a segment of active muscles and activation patterns of the active muscles based on the identified section, and constructing a displayable map of the locations and the activation patterns, wherein patterns corresponding to different active muscles are distinguishable on the map.

摘要： Some embodiments include processing data via an executable file on a monitor to reduce the dimensionality of the data being transmitted over the wireless network. The output of the executable file also encrypts the data before being transmitted wireless to a remote server. The remote server receives the transmitted data and makes likelihood inferences based on the recorded data.

摘要： The present disclosure relates to a cardiac monitoring device and systems/methods relating to same. Preferred embodiments may include adhesive layers having channels for transpiring moisture to promote long term adhesion of the device to a subject. The adhesive layer may be surrounded by a non-adhesive lining to inhibit substrate layers from folding under the adhesive. In some embodiments, the adhesive layer may be replaceable. In some embodiments, the adhesive layer may extend beneath a substrate coupled to a housing but not be adhered to the overlying substrate layers. The angles of the edges of the adhesive layer may be configured to minimize peeling forces. Substrate layers above the adhesive layer may be perforated to promote transpiration of moisture and/or provide conformability to the substrate. The perforations may promote anisotropic resistance to compression and/or extension of the substrate.

摘要： A data acquisition device includes an integrated circuit and an information processor. The integrated circuit has a first terminal for receiving a master/slave switching signal upon start of data acquisition, an ADC for converting analog input data to digital data, and an output terminal for outputting the digital data. The information processor generates the master/slave switching signal, and has a second terminal connected to the first terminal and for outputting the master/slave switching signal, and an input terminal connected to the output terminal and for receiving the digital data. The information processor operates in the master mode when the integrated circuit operates in the slave mode. The information processor operates in the slave when the integrated circuit operates in the master mode. The integrated circuit outputs the digital data when operating in the master mode according to the master/slave switching signal.

摘要： Devices, systems, and methods herein relate to electromyography (EMG) that may be used in diagnostic and/or therapeutic applications, including but not limited to electrophysiological study of muscles in the body relating to neuromuscular function and/or disorders. Sensor assemblies and methods are described herein for non-invasively generating an EMG signal corresponding to muscle tissue where the sensor may be positioned directly on a surface of the muscle tissue including any associated membrane (e.g., mucosal, endothelial, synovial) overlying the muscle tissue. A sensor assembly may include one or more pairs of closely spaced, atraumatic electrodes in a bipolar or multipolar configuration. The first and second electrodes may be applied against a surface of muscle tissue (that may include a membrane overlying the muscle) and receive electrical activity signal data corresponding to an electrical potential difference of the portion of muscle between the electrodes.
