    摘要: A fluidic device controls fluid flow in channel from a source to a drain. In some embodiments, the fluidic devices comprises a gate, a channel, and an obstruction. The gate comprises at least one chamber whose volume increases with fluid pressure. A high pressure state of the gate corresponds to a first chamber size and a low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size. The obstruction controls a rate of fluid flow within the channel based on the fluid pressure in the gate. The obstruction induces at most a first flow rate of fluid in the channel in accordance with the low pressure state of the gate, and at least a second flow rate of the fluid in the channel in accordance with the high pressure state of the gate.

    摘要: Example devices include a fluidic device, such as a fluidic valve, including a body formed from a rigid body material including a fluidic source, a fluidic drain, and a fluidic gate, each of which may have a fluid connection with a chamber, or a portion thereof. The device may further include a gate transmission element, located within the chamber, that is controllable between at least a first position and a second position using a gate pressure received through the fluidic drain. Adjustment of the position of the gate transmission element may allow control of fluid flow through the device. Other devices, methods, systems, and computer-readable media are also disclosed.

    摘要: The disclosed apparatus may include a fluidic channel connecting an inlet port and an outlet port. The apparatus may further include a gate transmission element configured to limit fluid flow between the inlet port and the outlet port. Still further, the apparatus may include a primary gate terminal connected to a second fluidic inlet port, where pressure or force at the primary gate may at least partially control movement of the gate transmission element. The apparatus may also include a secondary gate terminal connected to the second fluidic inlet port. Pressure or force at the secondary gate may at least partially control movement of the gate transmission element. Various other associated methods, systems, and computer-readable media are also disclosed.

    摘要: Microfluidic devices may include a first inlet port for conveying a first fluid exhibiting a first pressure into the fluidic device, a second inlet port for conveying a second fluid exhibiting a second pressure into the fluidic device, an output port for conveying one of the first fluid or the second fluid out of the fluidic device, and a piston that is movable between a first position that inhibits fluid flow from the second inlet port to the output port and a second position that inhibits fluid flow from the first inlet port to the output port. Movement of the piston between the first and second positions may be determined by control pressure applied against a control gate of the piston. A flange of the piston may have an outer diameter of about 10 mm or less. Various other related methods and systems are also disclosed.

    摘要: A fluidic device may include inlet ports, input ports, one or more output ports, fluid channels each configured to route fluid from one of the inlet ports to one of the one or more output ports, and pistons. In some examples, each piston may include (1) a restricting gate transmission element configured to block, when the piston is in a first position, and unblock, when the piston is in a second position, one of the fluid channels, (2) a controlling gate transmission element configured to interface with a first control pressure that, when applied to the controlling gate transmission element, forces the piston towards the first position, and (3) an additional controlling gate transmission element configured to interface with a second control pressure that, when applied to the additional controlling gate transmission element, forces the piston towards the second position. Various other related devices and systems are also disclosed.
