摘要： Methods of fabricating electromagnet assemblies are disclosed. In one embodiment, a includes forming a first helix and a second helix, each helix having a first end and a second end and a substantially oval cross-section, the cross-section having a major axis, each helix being configured to concentrate electromagnetic flux at a midpoint on the major axis. Each helix is bent at an angle and offset from the major axis, resulting in a first planar surface including the major axis and a second planar surface. The first and second helixes are oriented such that the outer edges of the respective second planar surfaces coincide and the outer edges of the respective first planar surfaces are in diametric opposition. The first and second helixes are affixed by their respective second planar surfaces, and electrically connected by their respective second ends.

摘要： A system for active dynamic balancing of a rotating tool driven by a motor having a shaft supported by a first and second bearing on opposing sides of the motor includes an acceleration sensing assembly configured to sense radial accelerations on the shaft producing an acceleration signal indicative of the radial accelerations. A correcting mass assembly is configured to rotate with the shaft and to move at least one mass radially to the shaft responsive to a correcting signal. A controller is configured to receive the acceleration signal generating a correcting signal by means of a closed loop iterative algorithm.

摘要： An ergonomic sander handle for clamping onto a sanding device so that the ergonomic handle can be comfortably gripped by a worker and used to apply the sanding device to a surface, is provided. The ergonomic handle includes an elongate body, a clamp head and a bearing. The elongate body is typically a cylindrical aluminum tube with padding for easy and comfortable gripping. One end of the elongate body is attached the clamp head that attaches to the sanding device. The other end of the elongate body is attached to the bearing which may include a pair of roller balls. To sand a surface, the worker grips the elongate body in a power grip (without significant wrist flexion or deviation) and applies pressure to urge sanding device and the bearing onto the surface. The power grip minimizes loads on the wrist and hand which reduces the likelihood of musculoskeletal trauma.

摘要： An apparatus for a pickup truck box cover includes a frame having a generally flat rectangular shape and configured to reside in a plane generally perpendicular to a bed of the pickup truck and proximate a back of a cab of the pickup truck. A means joins the frame to a frame of the pickup truck. A means joins the frame to the pickup truck box. A top surface is removably joined to the frame and configured to extend back from a top portion of the cab of the pickup truck along a sloping plane intersecting a plane containing the bed of the pickup truck. Side panels are removably joined to the frame and configured to extend from the top surface to the bed of the pickup truck where, in conjunction with the pickup truck, a shape resembling generally flat bottom airfoil is formed.
