Abstract: Methods and systems for decimating a waveform are disclosed. The method includes dividing the waveform into a plurality of sections and performing a second order derivative operation on the sections and determining corresponding derivative values. The method further includes classifying the section as a linear region if the derivative value is within a threshold range and classifying the section as a non-linear region if the derivative value is outside the threshold range. The method also includes decimating data points of the linear regions using a coarse decimation to generate coarsely decimated data points and decimating data points of the non-linear regions using a fine decimation to generate finely decimated data points. The method also includes reconstructing a waveform using the coarsely and finely decimated data points.

Abstract: A transcranial magnetic stimulation (TMS) device has at least one capacitor. A charging circuit charges the capacitor. The TMS device includes a magnetic coil for delivering magnetic pulses to a person's body. A bleed resistor is within the TMS device to minimize forces applied to the bleed resistor where the bleed resistor is aligned with magnetic field lines generated by the magnetic pulses.

Abstract: A transcranial magnetic stimulation (TMS) device for the treatment of migraine headaches which includes at least one capacitor as well as a charging circuit for charging the capacitor contained in the TMS device. A magnetic coil delivers a magnetic pulse upon discharge of the capacitor. Inner and outer end wire segments of the magnetic coil are oriented parallel to a direction of magnetic field lines of the magnetic pulse.

Abstract: A control cartridge has a circuit board that includes a Hall effect sensor, the position of which is fixed in a housing that has a cam. The control cartridge includes a shaft that carries a magnet and that rotates and translates with respect to the housing. The shaft has a cam follower that engages the cam and translates the shaft with respect to the housing when the shaft is rotated with respect to the housing in one direction but not in an opposite direction. The control cartridge is shown as part of a control handle for a motorcycle in which the relative angular position of the shaft with respect to the Hall effect sensor is used to control engine speed manually while the relative axial position of the shaft with respect to the Hall effect sensor is used to deactivate a cruise control.
