Minnesota micromotor

The Doppler interferometer and imaging guidewire of the present invention together form images based on information gathered during scanning in as little as a tenth of a second, which is faster than the time between even the fastest heart beat of a patient.

This means that the motor's control circuit must successively feed all electrodes 10 about times for rotor 3 to complete one revolution about pivot 4. The motor's control circuit is arranged in this case successively and selectively to connect each one of electrodes 10 to the second terminal of the device's source of supply when motor 1 is required to operate.

The lens preferably has a focal distance of around to microns. A high thermal resistance was the leading feature touted by device manufacturers in this segment. A movable mirror in the reference arm of the interferometer is moved in a sequence of positions, and the intensity of the interfering light is measured for each position, thus providing a plot of the reflected intensities as a function of depth into the tissue.

At such a high electric field, strong alignment forces in the w and L direction are generated which move the moving member to be aligned with the stator. Use of a silicon nitride for a wear-resistant coating in the micromotor makes a doped oxide film such as phosphosilicate glass attractive as the sacrificial layers.

Applicants have applied the foregoing to a capacitor having two connecting parallel plates separated by a micron wide insulting layer of air to create a variable capacitance microactuator.

A machine as claimed in claim 11 wherein the bearing is of the type that is aligned with a rotor formed by the steps of: The second structural layer is then placed over the sacrificial layer along the edge of the moving member and connected to the substrate to form a self-aligned bearing.

The electrodes are positioned substantially parallel to the central cylindrical axis of the throughbore and are spaced apart within a wall of the stator.

Active stabilization of the axial position of the rotor is accomplished through separate control of the drive charge applied to the upper and lower stator electrodes at low bandwidths relative to the frequency of rotation. A fiber, incorporated into the intravascular catheter is used for delivering light from an external source such as a superluminescent diode, to the tissue to be diagnosed, and for collecting the retroreflected light.

The present invention includes a harmonic motion micromotor comprising a stator having an inner surface defining a throughbore. The three phases are activated in a timed sequence so as to cause a smooth rotation of rotor The series of sense elements 50 are evenly spaced around center bearing 73 and are positioned below a rotor electrode layer 16 which is incorporated into a central part of rotor Be sure to register in advance so you can enjoy early-bird savings, reserve seats at the Category 1 Core courses and book your hotel rooms nearby.

Correspondingly, the torque densities of microactuators based on these energy densities are comparable, unlike conventional macroactuators where MQS is much stronger than EQS actuation. The moving member and stator have very smooth surfaces.

The latter goal can be pursued by operation of the micromotor in vacuum for elimination of viscous drag. According to the Paschen curve for air, an electric potential of about V can be supported across the gap at atmospheric pressure and room temperature In an integrated power circuit, this problem is less severe and consequently, the performance of a one-chip microactuator system may be superior.

The coupling includes electrodeson an interior surface which come into electrical contact with bands 96 and 98 when the coupling is in an operable position on the proximal end of the guidewire.

The method further includes the steps of forming an image of the site and evaluating information presented in the image for developing an interventional strategy. Minnesota Micromotors Marketing Assignment: In principal, a variety of electrostatic microactuator topologies can be derived by translating the many traditional magnetostatic motors through the duality relations.

The average stress and its variation through the thickness of the freestanding microstructure must be controlled to avoid buckling or warpage.

The use of low coherence interferometry for imaging biological tissue is generally known. In the preferred embodiment, the flexible region includes first and second spiral-wound wire segments 45 and 47, the first segment 45 wound over a safety wire Only extreme temperature variations will cause a change in breakdown voltage, if the gas density remains the same.

A hermetic housing mounted proximate the distal end of the elongated body is provided which encloses a mirror mechanism.

The shift is described by the following formula: A machine as claimed in claim 1 wherein the stator includes a series of stator electrode segments, the electrodes of said series being charged in sequence to induce attracting charge in the movable member.

In such a motor, the rotor comprises a series of permanently positioned charges. An aperture underlying the rotor at some radius is micromachined into the substrate.
