The array read circuits sample magnetic bits in the array, apply a write current pulse to the magnetic bits to set them to a first logic state, resample the magnetic bits, and comparing the results of sampling and resampling to determine the bit state for each magnetic bit.

Differential current measurements to determine ion current in the presence of leakage current
An ion chamber provides a current representative of its characteristics as affected by external conditions, e.g., clean air or smoke. A direct current (dc) voltage is applied to the ion chamber at a first polarity and the resulting current through the ion chamber and parasitic leakage current is measured at the first polarity, then the dc voltage is applied to the ion chamber at a second polarity opposite the first polarity, and the resulting current through the ion chamber and parasitic leakage current is measured at the second polarity.

Conversion of pharmaceuticals and chemicals into different compounds by polarity reversal electrolysis
A polarity-reversal electrolysis process. The process uses a reactor that has at least one pair of spaced electrodes, and a controlled polarity-reversing power supply that is constructed and arranged to provide polarity-reversed power to the electrodes.
There is disclosed an envelope tracking amplification stage comprising an input path and an envelope path and a delay stage in one of the input path and the envelope path, the delay of the delay stage being determined in dependence on the slope polarity of a signal representing the input and whether the signal in the input path leads or lags the signal in the envelope path.. .
