Abstract: Methods for initiating chemical reactions in a wellbore include delivering one or more reactive components via a carrier fluid to the wellbore. The one or more reactive components delivered to the wellbore are configured to enable one or more chemical reactions to occur. The one or more chemical reactions are carried out until a threshold volume of the one or more reactive components is delivered to the wellbore.

Abstract: A method for measuring a neural response to a stimulus. Measurement circuitry is settled prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.

Abstract: Disclosed is an automated programming system for a neuromodulation device that is configured to assist a clinician to efficiently program the neuromodulation device for a particular patient. In particular, the assisted programming system comprises a stimulation user interface control that is configured to cause the intensity of the neural stimulus to ramp up with time as long as the patient continues to interact with the control. The value of stimulus intensity at which the patient ceases to interact with the control is recorded as a significant perceptual marker upon which subsequent steps in the assisted programming workflow are based. This user interface design takes advantage of the human withdrawal reflex, whereby the patient is likely to instinctively release the button upon receiving uncomfortable stimulation. The design therefore minimises the training burden placed on the patient in using the assisted programming system.

Abstract: A method of controlling a neural stimulus by use of feedback. The neural stimulus is applied to a neural pathway in order to give rise to an evoked action potential on the neural pathway. The stimulus is defined by at least one stimulus parameter. A neural compound action potential response evoked by the stimulus is measured. From the measured evoked response a feedback variable is derived. A feedback loop is completed by using the feedback variable to control the at least one stimulus parameter value. The feedback loop adaptively compensates for changes in a gain of the feedback loop caused by electrode movement relative to the neural pathway.

Abstract: Disclosed are methods and devices for analysing signal windows captured subsequent to delivered neural stimuli and for providing a quality score for each signal window. The quality score is indicative of how closely the captured signal window resembles, or how likely that the captured signal window contains, an ECAP. The quality score may be provided to a process supervising a feedback loop of the closed-loop neural stimulation device delivering the stimuli and capturing the signal windows to ensure the delivered stimuli are appropriate. For example, if the score falls below a predetermined threshold, the supervisor may take a mitigation action to prevent inappropriate adjustment to the intensity of the delivered stimuli by the feedback loop, such as suspending operation of the feedback loop.

Ions are directed from an ionization source toward at least one of the first and second opposing major surfaces of the glass ribbon and/or an electrode directs particles away from at least one of the first and second opposing major surfaces of the glass ribbon. Such can reduce a density of particles on a major surface of the glass article formed from the glass ribbon.

Abstract: Described is implementing a decision capturing and tracking process, which may be used for any type of decision capturing process, such as a voting process or other process that captures and subsequently counts decisions made by individuals. Provided is a streamlined, convenient, and secure method for implementing a voting system that overcomes many of the challenges present in existing systems, while significantly improving the functionality of computer systems by reducing complexity, storage and processing requirements. This is achieved by using the position of an individual's body as the mechanism for capturing the individual's decision, which allows for an improved process. A system is provided that automatically captures a plurality of an individual's decisions as the individual continuously travels (e.g., walks, rolls, rides, drives) along a path and makes choices along the way. The captured decisions may then be used for counting, tracking, auditing, smart contracts, tokens, currencies, or other uses.

Abstract: A method for processing a neural measurement obtained in the presence of artifact, in order to detect whether a neural response is present in the neural measurement. A neural measurement is obtained from one or more sense electrodes. The neural measurement is correlated against a filter template, the filter template comprising at least three half cycles of an alternating waveform, amplitude modulated by a window. From an output of the correlating, it is determined whether a neural response is present in the neural measurement.
