A reference current value IL of a stall current for determining whether to stop the motor when a foreign object or the like has become entangled between the webbing and an in-vehicle part can also be set to be small in correspondence to the reduced current value I1.

Abstract: A user supported portable sail assembly and method uses the force of the wind to help propel a user on a mobile device such as skis, snowboards, skateboards, in-line or ice skates, for example, in a controlled and safe manner. A sail is attached to the ends of a pair of parallel, flexible poles which the user holds onto, usually one pole in each hand. The user orients the sail to optimize direction and speed. As the sail catches wind currents, the poles flex and form an optimal airfoil. Should the user wish to stop using the sail assembly, the user simply brings the poles together and brakes or glides to a gentle stop. The poles may be constructed of multiple interlocking segments for easy and quick disassembly and compact stowing.

Abstract: This invention provides a post hole digger having a first, traverse pivot point, located on the medial portions of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point of the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.

Abstract: An etchable plate-shaped material is used as a vacuum suction pad 31. On one surface thereof, a large number of independent protruded portions and recessed portions are formed to provide a suction part 33b. Further, a periphery of the suction part is annularly formed to provide an airtight part 33a.
