A method of loading an IOL having an optic and a leading haptic into a cartridge, comprising folding the leading haptic radially inward relative to the optic as the IOL moves into a lumen of the cartridge, by using a proximal end feature of the cartridge. According to the production method, a fat or oil is reacted with an alcohol to give a fatty acid alkyl ester andor glycerin suitably used in a food or fuel application, etc. The implicit log-off procedure reduces the risks resulting from transiting to an insecure site while remaining logged onto a secure site. In another aspect, embodiments of the present invention provide methods and systems for neighbor node discovery that adapt to network andor node operating conditions and that dynamically maintain a neighbor node set at a given node according to these conditions.
