20140311497 | LUNG VENTILATION DEVICE - A lung ventilation device has a stem to fit in a trachea, having at least two ventilation passageways communicating with distal passageways configured to fit in the bronchi at the carina. There is a positioning balloon to engage the walls at the carina when inflated. The positioning balloon has a proximal annular portion surrounding a distal end of the stem, and a plurality of annular distal portions, each surrounding a distal passageway end. The distal balloon portions are extensions of the proximal balloon portion. There may be a frangible link between the distal passageways, to break to separate the distal passageways in situ for bronchi entry as the positioning balloon is inflated. There may be stylets extending along the stem and arranged to provide stiffness to the distal passageways during device advancement in the trachea. | 10-23-2014 |

20140318683 | APPARATUS AND METHOD FOR SEMICONDUCTOR WAFER LEVELING, FORCE BALANCING AND CONTACT SENSING - A wafer bonder apparatus, includes a lower chuck, an upper chuck, a process chamber and three adjustment mechanisms. The three adjustment mechanisms are arranged around a top lid spaced apart from each other and are located outside of the process chamber. Each adjustment mechanism includes a component for sensing contact to the upper chuck, a component for adjusting the pre-load force of the upper chuck, and a component for leveling the upper chuck. | 10-30-2014 |
20140319786 | APPARATUS AND METHOD FOR ALIGNING AND CENTERING WAFERS - A device for locating and engaging a notch on the perimeter of a circular wafer includes a notch locating component and a first plate. The notch locating component is configured to move linearly along a first axis and includes a front elongated component extending along a second axis perpendicular to the first axis and having a front surface, a back surface opposite to the front surface and a first protrusion extending from the front surface of the elongated component. The first protrusion has a shape complementing the shape of a notch formed on the perimeter of a circular wafer. As the notch locating component is driven toward the perimeter of the circular wafer along the first axis, a distance between the back surface of the elongated component and a front surface of the first plate is measured and the value of the measured distance is used to determine engagement of the first protrusion with the notch. | 10-30-2014 |

20080236668 | Microfluidic Valve - A microfluidic valve. A microfluidic channel is formed in a substrate. A cooling element cools a substance in the channel to inhibit flow of the substance through the channel. A heating element warms the substance to overcome the effect of the cooling and enable the substance to flow through the channel. The valve may serve as a component of a microfluidic device that in turn may be part of a microfluidic system. | 10-02-2008 |
