A line marker has a wheeled frame on which an outrigger arm is pivotally carried. The method includes identifying wireless links from a set of selected mesh network routing links, that have a link quality below a predetermined quality threshold, and providing a network manager with a link list that lists and prioritizes the identified wireless links according to a degree of impact each identified wireless link has on performance of the mesh network. The driving method comprises: providing a detecting unit for detecting rotating position and rotating speed of the vibration motor and accordingly generating a detecting result; and providing a control unit for controlling acceleration and deceleration of the vibration motor according to the detecting result. A displaceable member is attached to the flexible body at the region of greater stiffness. The invention can inhibit release of sulfate ions, ammonium ions and so on from the pellicle frame and thereby reduce the occurrence of haze under exposure environment. Methods of weight management and caloric reduction by orally administering the ingestible compositions are included.
