The present invention relates to an electronic flash device capable of dimming control, particularly with the objective of enhancing the dimming precision in weak light emissions. The method comprises masking of particular attributes of a dataset which are to be preserved in confidentiality, followed by a shuffling step comprising sorting the transformed dataset and a transformed confidential attribute in accordance with the same rank order criteria. An instantaneous phase detector calculates the instantaneous phase of the one or more symbols associated with the input signal. By controlling the length of the transmission line conductors in these areas compared to the lengths in which the currents travel in opposite directions, the overall impedance of the oscillator can be increased. A spring is disposed in the cylinder abutting the remote indicator and urges the remote indicator toward the second housing member. Also provided is a method of adjusting the above stirrer device.
