An electronic stimulation device is adapted for electrically stimulating a target zone of an organism with relative low pain sensations without generating relative much sensations of paresthesia. The present invention also includes a method of manufacturing a metal electrode having an ignition tip for an ignition device, including forming a metal electrode having a firing tip portion; applying a noble metal preform to the firing tip portion; and reflowing the noble metal preform to form a noble metal firing tip. The teachings provide mean and standard deviation which were found to be within 3% from those computed by Monte Carlo simulation, while leakage and delay variations can be up to 3\xd7 and 1. The methods further include determining a distance between the corresponding pure gray color value and a selected color value. A remotely operable latch means locks the gate closed, preventing passage. The method for production of a polyfunctional compound includes conducting a Michael addition of a compound having a hydrogen atom of pKa\u226615 to a acrylate or a acrylamide, in which at least one of the compounds and has a photoisomerization group andor a liquid-crystalline group.
