摘要： Glaucoma drainage devices including vario-stable valves and associated systems and methods are disclosed. A glaucoma drainage device includes a drainage lumen and a valve system coupled to the drainage lumen to control the flow of fluid through the drainage lumen. The valve system includes an adjustable valve with a diaphragm that is in communication with the drainage lumen and is movable to occupy varying amounts of the drainage lumen.

摘要： A method of manufacturing a valve for a fluid system is described herein. The method comprises determining a target cracking pressure for the valve of the fluid system, providing an inner wall having a first height and an outer wall having a second height, the first height varying from the second height by a height differential, and attaching a flexible membrane to the outer wall at the second height, wherein a central zone of the flexible membrane is in contact with the inner wall at the first height and the inner wall biases the flexible membrane from a neutral condition. The height differential is selected to provide resistance to displacement from the inner wall until pressure acting on the membrane exceeds the target cracking pressure.

摘要： An IOP control valve is disclosed. The IOP control valve comprises a corrugated membrane and a housing including a fluid inlet and a fluid outlet. The corrugated membrane is anchored within the housing to form a reference chamber on a first side of the corrugated membrane and a fluid flow channel on a second opposing side of the membrane. The reference chamber has a reference chamber pressure representative of atmospheric pressure. The fluid flow channel can selectively increase and decrease in size to permit fluid to flow from the fluid inlet to the fluid outlet. The corrugated membrane is configured to affect flow through the fluid flow channel from the fluid inlet to the fluid outlet by deflecting in response to pressure differentials of the reference chamber pressure and the fluid flow channel pressure acting on the opposing sides of the corrugated membrane.

摘要： This invention provides systems, materials, and methods of environmental modification with climate control materials. Climate control materials may have different properties such as optical properties, wettability, porosity, buoyancy, thermal conductivity, imperviousness, strength/breaking, source of materials, and biodegradability, that may assist with local environmental modification. Climate control materials may also incorporate different designs that may allow them to advantageously affect the local albedo and evaporation rate and thereby modify the local environment. Effects of such climate control materials may be reversible and may minimize ecological harm.

摘要： A switching device for controlling fluid motion. The device includes a capillary filled with a first fluid into which a wall-confined bubble of a second fluid is introduced to achieve a first switching event. Capillary geometry and wetting properties provide a pressure-related asymmetric energy potential distribution for controlling the flow of the bubble, and the device is called an asymmetric bubble chamber, or ABC. The bubble is initially trapped in an energy potential well, and upon increase of its volume moves from the well into a region of low energy potential to achieve a second switching event. The first switching event may be blocking of a fluid channel or reflection of an optical beam in an optical crosspoint switch, while the second switching event may be unblocking of a fluid channel or restoration of transmission of an optical beam. The increase in bubble volume between the first and second switching events can act as the stroke of a fluidic piston to pump a volume the first fluid within the capillary. The device can be employed to thermally degas a liquid. The use of large-magnitude geometry-related energy potentials permits rapid cyclical operation of the device in a manner resistant to mechanical shock.
摘要翻译：一种用于控制流体运动的开关装置。该装置包括填充有第一流体的毛细管，其中引入第二流体的壁限制气泡以实现第一切换事件。毛细管几何形状和润湿性能提供了压力相关的不对称能量势能分布，用于控制气泡的流动，该装置称为不对称气泡室（ABC）。气泡最初被捕获在能量势阱中，并且当其体积的增加从井移动到低能量潜能的区域以实现第二切换事件时。第一切换事件可能阻塞光交叉点开关中的流体通道或光束的反射，而第二切换事件可以解除流体通道的阻塞或光束的传输恢复。第一和第二切换事件之间的气泡体积的增加可以作为流体活塞的冲程来泵送毛细管内的第一流体的体积。该装置可用于对液体进行热脱气。使用大幅度几何相关的能量电位允许以机械冲击的方式快速地周期性地操作装置。

摘要： A micromachined signal switch for vertical displacement includes a fixed substrate having at least one signal line and includes an actuator substrate that is thermally actuated to selectively connect a second signal line to the first signal line. The actuator substrate includes a plurality of legs constructed of materials having sufficiently different coefficients of thermal expansion to create stresses that arc the legs when the legs are subjected to elevated temperatures. In the preferred embodiment, a first material for forming the legs is silicon and a second material is a metal, such as electroplated nickel. A displaceable contact region may be formed integrally with the actuator substrate, but the contact region is preferably a region of an interposer substrate between the fixed substrate and the actuator substrate. The displaceable contact region has a raised position in which the signal line on the fixed substrate is "off" and has a lowered position in which a conductive member on the contact region is positioned to provide electrical communication to the signal line.
