    Abstract: This invention discloses such a convenient navigation system and navigatable capsules which are useful for remote-controlled imaging, biopsy and programmable drug release within the body of an animal. The components of the system comprise a capsule dimensioned and shaped to move within the body. An anisotropic magnetic component is mechanically coupled to the capsule to move or orient the body in relation to an applied magnetic field, and a magnetic field generating system external of the body generates a three dimensionally oriented magnetic field within the body to move or orient capsule.

    Abstract: An improved process for fabricating emitter structures from nanowires, wherein the nanowires are coated with a magnetic material to allow useful alignment of the wires in the emitter array, and techniques are utilized to provide desirable protrusion of the aligned nanowires in the final structure. In one embodiment, nanowires at least partially coated by a magnetic material are provided, the nanowires having an average length of about 0.1 &mgr;m to about 10,000 &mgr;m. The nanowires are mixed in a liquid medium, and a magnetic field is applied to align the nanowires. The liquid medium is provided with a precursor material capable of consolidation into a solid matrix, e.g., conductive particles or a metal salt, the matrix securing the nanowires in an aligned orientation. A portion of the aligned nanowires are exposed, e.g., by etching a surface portion of the matrix material, to provide desirable nanowire tip protrusion.

    Abstract: A MEMs device comprises a component layer including a frame structure and at least one component movably coupled to the frame and an actuator layer including at least one conductive path and at least one actuator for moving the component. The component layer and the actuator layer are bonded together with solder or other materials in lateral alignment. Advantageously the layers are provided with metallization pads and are bonded together in lateral alignment with predetermined vertical gap spacing by solder bonds between the pads. In a preferred embodiment the MEMs device, however bonded, comprises a component layer, an actuator layer and an intervening spacer. The spacer provides the walls of a cavity between the component and the pertinent actuators to permit movement of the component. The walls cover the bulk of the peripheral boundary of the cavity to provide aerodynamic isolation. Advantageously the walls are conductive to provide electrostatic isolation. The device has particular utility in optical cross connection, variable attenuation and power gain equalization.

    Abstract: A method and apparatus for providing easy access to a service provider that provides service over a communications system. In accordance with the present invention, a caller that wishes to gains access to the service provider simply needs to make a single call to a so-called queuing system, and hang up. The queuing system obtains information regarding the caller such as the caller's name, address and phone number, makes a connection with the service provider, calls-back the caller when the connection is made, and connects the caller to the service provider through the connection. The caller is thereby connected to the service provider without having to spend a substantial amount of his/her free time making calls. This is particularly advantageous when the service provider is popular or oversubscribed (e.g. a service that provides Super Bowl tickets).

    Abstract: An article comprising an alloy exhibiting high magnetostriction in relatively low applied magnetic fields is provided, the alloy capable of being formed in a relatively easy manner and having desirable physical properties. The Co--Fe alloy of the invention exhibits a magnetostriction of at least 100.times.10.sup.-6 in a magnetic field less than 400 Oe, advantageously in a magnetic field less than 100 Oe. The alloy is formed by plastically deforming the alloy, e.g., by cold rolling, to a reduction in cross-sectional area of at least 50%, and then heat treating the alloy to induce recrystallization. This combination of plastic deformation and recrystallization was found to provide desirable grain growth and microstructure. The resultant alloy is useful in a variety of device components, including transducers, frequency filters, signal delay lines, and optical fiber grating devices.
