20100039687 | Apparatus for Performing Confocal Endoscopy - A method for manufacturing a microscanner having a micro mirror is disclosed. Initially, a two-axis self-aligned vertical comb-drive microscanner is fabricated from a bonded silicon-on-insulator-silicon (SOI) silicon wafer. By depositing a thin film of aluminum on the surface, a SOI silicon wafer can provide about 90% reflectivity at 633 nm. A 2.5 μm misalignment tolerance can be achieved for the critical backside alignment step. As a result, confocal images with 1 μm resolution can be acquired using a microscanner having SOI silicon wafer mirrors. | 02-18-2010 |

20110062110 | Method for Fabricating a Micromirror with Self-Aligned Actuators - A method of fabricating a micromirror is disclosed. Initially, a set of coarse features is formed in a low-temperature oxide (LTO) layer deposited on a front side of a wafer. A set of fine features is then formed in a photosensitive material layer deposited on top of the LTO layer, and the fine features are constrained laterally within the coarse features. Next, a portion of the LTO layer is removed to align the width of the coarse features with the width of the fine features. The first silicon dioxide layer and the first and second silicon device layers are subsequently etched to form stator comb fingers and rotor comb fingers. Finally, a rotatable mirror is formed by removing a portion of the substrate on a back side of the wafer, and the silicon dioxide layers from the front and back sides of the wafer. | 03-17-2011 |
20110160744 | Optically-implemented microsurgery system and approach - According to an example embodiment of the present invention, a vibration-actuated microsurgical system includes an optical force detection arrangement having an optical encoding device configured to modulate an intensity of light in response to a displacement of a portion of the microsurgical system. Light sensing circuitry is configured to detect a force applied to the microsurgical system (e.g., and thereby to a sample) based on the intensity of light sensed from the optical encoding device. This detected force is used in controlling the application of the microsurgical system. | 06-30-2011 |

20110303638 | Method for Fabricating a Micromirror - A method for fabricating a micromirror is disclosed. A set of coarse features is formed in a low-temperature oxide (LTO) layer deposited on a front side of a wafer. A set of fine features is then formed in a photosensitive material layer deposited on top of the LTO layer. After removing a portion of the LTO layer to align the width of the coarse features with the width of the fine features, the first silicon dioxide layer and the first and second silicon device layers are etched to form stator comb fingers and rotor comb fingers accordingly. Finally, a portion of the substrate on a back side of the wafer is removed, and the silicon dioxide layers are removed from the front and back sides of the wafer to form a rotatable mirror. | 12-15-2011 |
20120281265 | HANDHELD IMAGING PROBE - A handheld imaging probe for performing optical coherence tomography is disclosed. The handheld imaging probe includes a lens tube and a housing. The lens tube contains an objective lens and a polycarbonate sheet. The polycarbonate sheet provides a bio-safe contact with a tissue sample to be examined.

20130075318 | Apparatus for Isolating Rare Cells from Blood Samples - An apparatus for isolating rare cells from a blood sample is disclosed. The apparatus includes a reservoir for supplying the blood sample and a pump for receiving the blood sample. The apparatus also includes a microchip and a set of magnets. The microchip has a microchannel formed between the microchip and a glass slide. The microchannel is connected between the reservoir and the pump to allow the blood sample to flow from the reservoir to the pump. The set of magnets is located adjacent to the glass slide to form a magnetic gradient along the glass slide on which rare cells can be isolated from the blood sample. | 03-28-2013 |
20130301095 | FREQUENCY TUNABLE MICROMIRROR - An optical imaging system having two micromirrors is disclosed. Each of the two micromirrors can be rotated by a first set of combdrive actuators along a first axis and a second set of combdrive actuators along a second axis. Each of the first and second set of combdrive actuators includes multiple stator comb fingers and multiple rotor comb fingers capable of rotating about a torsion bar. One of the micromirrors can be tuned by applying a current to the torsion bar to change the Young's modulus of the torsion bar via thermoelectrical heating of the torsion bar. | 11-14-2013 |
