Abstract: The present invention pertains to vibration devices (100) that do not require a rotating mass. In accordance with aspects of the invention, a coil (104) causes a plunger (102) to move linearly. A spring device (106) is coupled to one end of the plunger (102). Activation of the coil (104) causes the plunger (102) to move in a first direction relative to a body and coil deactivation enables the spring device (106) to move the plunger (102) in an opposite direction relative to the body. Activating the coil (104) at a predetermined frequency causes vibration of the plunger (102). Vibratory forces are transferred via the spring device (106) and coil onto the body at predetermined locations. Opposing spring devices (146a, 146b) may be affixed to either end of the plunger. Spring devices (106) may be linear or non-linear. Such spring devices (106) may be used in conjunction with magnetic spring devices (308). A controller (425) and a driver circuit (422) may be used to control system operation.

Abstract: A magnetic spring actuator comprising a ring (90), a piston (92) movably disposed inside of the ring, and a non-magnetic holding cylinder (94). At least one of the ring and the piston is magnetic. Due to a magnetic force caused by at least one of the ring and the piston, the piston is initially located in a first position with respect to the ring. Application of an outside force results in movement of the piston to a second position with respect to the ring. The magnetic force produces a return force for causing the piston to return to the tirst position with respect to the ring. Alternatively, the piston can be fixed and the ring can be adapted for moving with respect to the piston in a similar manner. A bi-metal coil spring (148) may be wound around the piston.

Abstract: Ferromagnetic material of an elongated object, such as a fiber optic cable (12), is permanently magnetized in a manner that results in a substantially cylindrically symmetric radial external magnetic field around the object. The radial external magnetic field varies periodically along the length of the object. If the wavelength of the periodic variations is long compared to the width (diameter) of the object, the strength of the radial external magnetic field decreases approximately inversely with distance from the object for distances that are small compared to the wavelength. Magnetization of the ferromagnetic material is achieved by a magnetizer having pairs (10) of counter-rotating mirror-image magnets adjacent to an object that is moved longitudinally relative to the magnets. By virtue of the magnetization, buried objects, such as pipes and cables can be detected magnetically at substantial distances from the objects.

Abstract: An energy transfer element comprises a magnetic core having a gap in a magnetic path. Magnetizable material producing an initial flux density is positioned in the gap. One or more power windings is wrapped around the magnetic path. When the magnetizable material is magnetized the flux density produced by the magnetized material is offset from the initial flux density. The core is a toroid magnetic core or is comprised of two core pieces. The magnetizable material is an unmagnetized magnet or a mixture of a suspension medium comprising uncured epoxy and magnetizable particles. The magnetizable particles are selected from a group comprising Neodymium Iron Boron (NdFeB) based materials or Samarium Cobalt (SmCo) based material.

Abstract: An apparatus includes a housing, a solenoid coil disposed within the housing, a pole member, and an armature configured to move from a first position to a second position when the solenoid coil is energized. A contact surface of the armature is spaced apart from a contact surface of the pole member by a first distance when the armature is in the first position, and a second distance when the armature is in the second position. The housing, the pole member and the armature collectively define a flux path characterized by a first reluctance when the armature is in the first position and a second reluctance when the armature is in the second position. The difference between the first reluctance and the second reluctance is less than about thirty percent of the value of the first reluctance.
