摘要： A thermally-activated gas extraction device that comprises a bubble capture chamber, an exhaust manifold, a tapered extraction chamber and an extraction heater associated with the tapered extraction chamber. The tapered extraction chamber extends from the bubble capture chamber towards the exhaust manifold and has a cross-sectional area that increases towards the exhaust manifold. A gas removal method in which the gas extraction device is provided, a bubble of gas is accumulated in the bubble capture chamber, a portion of the liquid in the tapered extraction chamber heated to nucleate a bubble of vapor, and the bubble of vapor is heated to explosively expand the bubble of vapor into contact with the walls of the tapered extraction chamber and into contact with the bubble of gas to form a composite bubble. Contact with the walls of the tapered extraction moves the composite bubble towards the exhaust manifold. Finally, heating of the composite bubble is discontinued to condense the vapor in the composite bubble.

摘要： A thin micromechanical device is fabricated in a way that is mechanically compatible with wafer handling for conventional-thickness wafers. A removable bonding layer bonds a fabrication wafer to a substantially conventional-thickness handle wafer to form a bonded wafer pair. The micromechanical device is formed in the fabrication wafer by subjecting the bonded wafer pair to processing including wafer handling for conventional-thickness wafers. The micromechanical device is formed to include part of the fabrication wafer. Finally, the bonding layer underlying the micromechanical device is removed to release the micromechanical device from the handle wafer.

摘要： A micromachined device for selectively switching an optical fiber between a first and a second position includes a working leg that undergoes a greater degree of thermal expansion than a second leg with the conduction of an electrical current through the two legs. In a preferred embodiment, the working leg has a cross-sectional area that is less than that of the second leg, thereby presenting a greater electrical resistance to the current flow. The legs are each fixed to a substrate at first ends and are interconnected at second ends that are free to move relative to the substrate. The difference in electrical resistance provides a differential in thermal expansion, as the working leg lengthens to a greater degree than the second leg. The working leg deforms the second leg and the optical fiber is pressed into a second position until current flow is terminated. In another embodiment, the differential in thermal expansion is created by ensuring that the second leg has less thermal isolation from the substrate than the thermal isolation of the working leg from the substrate.
摘要翻译：用于在第一位置和第二位置之间选择性地切换光纤的微机械加工装置包括经过两条腿的电流传导而经受比第二腿部更大程度的热膨胀的工作腿部。在优选实施例中，工作腿的横截面积小于第二腿的横截面积，从而对电流呈现更大的电阻。腿在第一端各自固定到基底，并且在相对于基底自由移动的第二端处互连。电阻的差异提供了热膨胀的差异，因为工作腿比第二条腿更大程度地延长。工作腿使第二腿变形，并将光纤压入第二位置，直到电流流动终止。在另一个实施例中，热膨胀差异是通过确保第二支腿与工作支脚与基板的热隔离相比具有比基板更小的热隔离来产生的。

摘要： A flow channel suitable for use with a peristaltic pump comprises: an upper wall having a bowed upward shape; a lower wall having one of a bowed downward shape and a flat shape; and one or more spacers between the upper wall and the lower wall disposed between lateral edges of the upper and lower walls, each spacer having a height. The upper wall, lower wall, and the one or more spacers define a lumen. When the upper wall is compressed toward the lower wall by compressing members, the one or more spacers limit vertical movement of the compressing members such that the lumen is maintained in an under-occluded condition. In some cases, the bowing of one of the upper and lower walls has a recurved shape.
