  • Patent number: 11026628
    Abstract: Disclosed herein are devices and methods of using a mobile or wearable device for the acquisition and spatial filtering of ECG signals from an electrode array. One variation of a mobile or wearable device comprises an array of electrodes, one or more reference electrodes, and a controller in communication with the electrodes. In one example, the one or more reference electrodes are located on a wrist-worn device (e.g., a watch), and the electrode array is located on an accessory device that may be contacted with a fingertip. One variation of a spatial filtering method comprises identifying the electrodes that have high levels of noise and excluding the ECG signals from those electrodes from further analyses. In another variation, a method of spatial filtering comprises identifying electrodes with low levels of noise and including only the ECG signals from those electrodes in further analyses.

    Abstract: A system may detect silent, internal articulation of words by a human user, by measuring low-voltage electrical signals at electrodes positioned on a user's skin. The measured signals may have been generated by neural activation of speech articulator muscles during the internal articulation. The system may detect the content of internally articulated words even though the internal articulation may be silent, may occur even when the user is not exhaling, and may occur without muscle movement that is detectable by another person. The system may react in real-time to this detected content. In some cases, the system reacts by providing audio feedback to the user via an earphone or a bone conduction transducer. In other cases, the system reacts by controlling another device, such as a luminaire or television. In other cases, the system reacts by sending a message to a device associated with another person.

  • Patent number: 10866638
    Abstract: A system includes a controllable device configured to provide a premises related service in an area. The system includes a neural device to be positioned with respect to a part of a body of a user and circuitry to process nerve signals detected in real-time. The system also includes a processor in communication with the circuitry, a memory and instructions stored in the memory for execution by the processor. Data stored in the memory associates each of some number of predetermined sets of nerve signals with a control instruction. Execution of the instructions configures the processor to use the stored data to analyze the real-time detected nerve signals to determine when real-time detected nerve signals correspond to one of the predetermined sets of nerve signals and generate a control data signal based on the associated control instruction to cause a controller to control an operation of the controllable device.

  • Patent number: 10864368
    Abstract: Techniques are disclosed for defining a homeostatic window for controlling delivery of electrical stimulation therapy to a patient. In one example, a method includes generating and delivering electrical stimulation therapy to tissue of a patient via electrodes. Further, the method includes adjusting a level of a parameter of the electrical stimulation therapy such that a signal of the patient is not less than a lower bound and not greater than an upper bound. The lower bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce one or more symptoms of a disease while the patient was receiving medication for reduction of the one or more symptoms. Further, the upper bound is determined to be the magnitude of the signal while receiving electrical stimulation therapy sufficient to reduce the one or more symptoms when the patient was not receiving the medication.

  • Patent number: 10849553
    Abstract: Systems and methods for sonifying electrical signals obtained from a living subject, particularly EEG signals, are disclosed. A time-domain signal representing the activity of an organ is obtained. A voltage of the time-domain signal over a time block is determined. An acoustic signal based on the time-domain signal over the time block is produced. The acoustic signal comprises one or more audibly discernible variations representative of the activity of the organ. If the determined voltage is over a threshold voltage, the time-domain signal is squelched over at least a portion of the time-block as the acoustic signal is produced. The time-domain signal can be squelched by ramping down the signal as an input to produce the acoustic signal. The frequency spectrum of the acoustic signal can also be adjusted as it is produced, such as by flattening the signal and/or attenuating high frequencies along the frequency spectrum of the signal.

  • Patent number: 10818393
    Abstract: A system for clinical decision support includes a database of previously-recorded waveform data from comparator-patients and a comparator module. The comparator module receives physiological waveform data for a patient and identifies a pattern in the patient's physiological waveform data, wherein the pattern accounts for a morphology and a rhythm of the patient's physiological waveform. The comparator module then compares the patient's physiological waveform data to the previously-recorded waveform data using a pattern recognition algorithm to detect the pattern in the previously-recorded waveform data to identify one or more matches. The comparator module further generates a result set based on the one or more matches.
