摘要： A mechanism is provided for registering a Common Information Model (CIM) provider to at least one Common Information Model Object Manager (CIMOM). The CIMOM pre-stores at least one class definition. The CIMOM sends information to the Common Information Model (CIM) provider in order for the CIM provider to determine the at least one CIMOM existing in a network. The CIMOM sends the at least one class definition stored in the CIMOM in order for the CIM provider to determine if the CIMOM comprises a class definition suitable for the CIM provider to operate. Responsive to the CIM provider determining that the CIMOM comprises a suitable class definition, the CMOM registers the CIM provider by recording an identifier of the CIM provider under the name of the class definition suitable to the CIM provider in the at least one CIMOM.

摘要： An electro-expulsive actuator capable of operating while encased within a flexible member is provided. The electro-expulsive actuator is designed to be resiliently flexible such that the flexible member remains fully deformable along its length. In addition, rather than striking the surface of or creating a shockwave within the flexible member, the actuator is disposed within the flexible member such that the deformation of the electro-expulsive actuator itself causes deformation of the flexible member thereby causing unwanted build-up of residues on the outer surface of the flexible member to be disrupted.

摘要： A nanometer-scale precision actuator comprises a base, an intermediate structure, an output interface, and two linear elements producing a controllable extension in the same longitudinal direction, each between a first and a second end. A first of the two elements has a first end fixed onto the intermediate structure and a second end fixed onto the base, a second of the two elements has a first end fixed onto the intermediate structure and a second end fixed to the output interface. The base and the intermediate structure are positioned in such a manner that the controllable extension of the second element produces a displacement of the actuator in a first direction and the controllable extension of the first element produces a displacement of the actuator in a second direction, opposite to the first direction, with respect to the base.

摘要： A power generating element includes a composite rod and a coil. The composite rod is obtained by joining a magnetostrictive rod through which lines of magnetic force pass axially and a reinforcing rod of a non-magnetic material for causing appropriate stress in the magnetostrictive rod and arranged in parallel with the magnetostrictive rod. The coil is provided so that the lines of magnetic force pass axially inside the coil and a voltage is generated based on variation of density of the lines of magnetic force. The power generating element is configured so that the density varies when the other end portion of the composite rod is displaced perpendicular to an axial direction of the composite rod with respect to one end portion of the composite rod to expand or contract the magnetostrictive rod.

摘要： An apparatus harvests electrical power from mechanical energy. The apparatus includes first and second load-bearing structures, a plurality of magnetostrictive elements, and an electrical circuit or coil. The load-bearing structures experience a force from an external source. The magnetostrictive elements are arranged between the load-bearing structures. The load-bearing structures transfer at least a portion of the force to at least one of the magnetostrictive elements. In this way, at least one of the magnetostrictive elements experiences the force transferred from the load-bearing structures. The force on the magnetostrictive element causes a change in magnetic flux of the magnetostrictive element. The electrical circuit or coil is disposed within a vicinity of the magnetostrictive element which experiences the force. The electrical circuit or coil generates electric power in response to the change in the magnetic flux of the magnetostrictive element.
