A new and distinct cultivar of Aloe plant named \u2018Tiki Tahi\u2019, characterized by its compact and upright plant habit; leaves arranged in a dense basal rosette; green-colored leaves with white-colored spots and margins; upright flowering stems; and good postproduction longevity. The head covering comprises a cap portion for covering the head, a pouch portion for encasing the hair and means to secure the head covering to the head. At least one of the transparency images at a dynamically-selected one of the hierarchical levels is overlaid over the geographic map according to which of the zoom levels is selected by a user in zooming of the geographic map, where the at least one transparency image is automatically selected without user input. The control unit may determine more than one gas output velocities. In addition, a precharge circuit is utilized to precharge the voltage on the first and second intermediate nodes to further increase the speed of the level shifter.
