An objective lens drive device includes an objective lens, a lens holder holding the objective lens, a fixed side member supporting the lens holder with a plurality of wires in a movable manner, a focusing and tracking drive mechanism, and a tilt drive mechanism for driving the lens holder in a tilt direction. An information platform determines one or more queries from at least one device. The apparatus also includes a spray system for directing a fluid at a portion of at least one of the carcasses. In use a user squeezes the exterior surface to latch the switch to cause the apparatus to light, and may then safely handle the apparatus. When positive frame, the voltage of the biased electrode, VE, is greater than the voltage the pixel electrode, VP; when negative frame, the voltage of the biased electrode, VE, is smaller than the voltage the pixel electrode, VP. Furthermore, a multiple tunnel management method is described herein which implemented by a host to address the problem that is related to synchronizing active tunnel and active link between the host and multiple next hop routers.
