The present invention provides an apparatus and method for limiting the power output of a transcutaneous electrical stimulator in response to changes in electrode impedance. The apparatus comprises pulse generating means having output terminals for delivering a pulsed electrical current through a circuit that contains at least two electrodes intended to be attached to the skin; measuring means coupled to the pulse generator and configured to measure the voltage across the output terminals in response to applied current; comparing means coupled to the measuring means and configured to compare the voltage measured during the pulse against a voltage threshold; and control means coupled to the comparing means and configured to limit the phase charge of the pulse when the measured voltage exceeds the voltage threshold.

Systems and methods for designing and manufacturing electromagnetic coils for use with a magnetic resonance imaging (“MRI”) system are described. More particularly, described here are methods for designing and manufacturing gradient coils for producing magnetic field gradients with greater peripheral nerve stimulation (“PNS”) thresholds relative to conventional gradient coils. The gradient coil design is constrained using an oracle penalty that is computed to account for a PNS requirement for the coil. In other applications, the oracle penalty can be used to optimize driving patterns for an electromagnetic stimulation system, such that a target PNS requirement is achieved.

An electromagnetic device mating with a frequency specific microcurrent (FSM) to operate contains: a signal capture apparatus arranged on a wire between two current output ports of the FSM and including a frequency capture module. The frequency capture module is configured to determine a current output frequency of the FSM, and the current output frequency of the FSM is converted into a signal by the frequency capture module so as to send the signal. The signal is a specific controlling signal calculated from the current output frequency which corresponds to the frequency capture module.

Gamification for a pelvic disorder regimen has a processor for operating a control module configured to define a programmable treatment regimen. A neurostimulator is connected to the processor and the control module. The neurostimulator applies electrical or magnetic signals to the user according to the programmable treatment regimen which includes at least one treatment task to be performed by the user. A gramification module calculates and stores a set of scores of the user in performing at least one task defined in the programmable treatment program associated with one or more events defined in the programmable treatment program to provide a score assigned to each task performance. A user interface is connected to the control module and provides the user with information associated with the scores attained by the user.

Certain substances (e.g., large molecules) that ordinarily cannot traverse the blood brain barrier can be introduced into the brain by applying an alternating electric field to the brain for a period of time, wherein the frequency of the alternating electric field is selected so that application of the alternating electric field increases permeability of the blood brain barrier. In some embodiments, the frequency of the alternating electric field is less than 190 kHz (e.g., 100 kHz). Once the permeability of the blood brain barrier has been increased, the substance is able to cross the blood brain barrier.

An intensity of fitness apparatus output can be customized for a user during a workout session. A user profile of the user may be accessed to determine a starting intensity value at which output is to be provided by the user's fitness apparatus. Based on this starting intensity value and on command data associated with a workout session, an intensity profile for the user may be determined (e.g., created), which is usable for controlling an intensity of the output of the fitness apparatus during the workout session. While media content featuring an instructor conducting the workout session is output on an output device, the user's device may send commands to the fitness apparatus to control the intensity of the output of the fitness apparatus in accordance with the starting intensity value and, subsequently, the intensity profile of the user.
