Composable PFET fluidic device

A device comprising:

• a first fluidic device coupled to a high pressure rail at a first pressure and a low pressure rail at a second pressure that is less than the first pressure, the first fluidic device comprising:
• a first channel configured to transport a fluid from a first source to a first drain, wherein the first source is coupled to the high pressure rail and is an input that fluid enters the channel, and the first drain includes an output path for fluid in the first channel;
• and
• a first gate configured to modulate a rate of fluid flow in the first channel by reducing a cross section of the first channel in accordance with logic instructions;
• and
• a second fluidic device comprising:
• a second channel configured to transport a fluid from a second source to a second drain, wherein the second source is an input that fluid enters the second channel, and the second drain includes an output path for fluid in the second channel;
• and
• a second gate configured to modulate a rate of fluid flow in the second channel by reducing a cross section of the second channel in accordance with the logic instructions of the first gate,
• wherein the first drain is coupled to the second source and wherein the device functionally is a NOR gate.

A fluidic device comprising:

• a gate comprised of at least one chamber whose volume expands with fluid pressure within the chamber causing a volume of the chamber to increase, wherein 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;
• a channel configured to transport a fluid from a source to a drain, wherein the source is an input that fluid enters the channel, and the drain is an output for the fluid in the channel;
• and
• a wedge that controls a rate of fluid flow between the source and the drain in accordance with the fluid pressure within the gate, the wedge configured to induce a first flow rate of the fluid in the channel in accordance with the low pressure state of the gate and a second flow rate of the fluid in the channel in accordance with the high pressure state of the gate, the second flow rate greater than the first flow rate, wherein the gate comprises a first chamber and a second chamber, the first chamber located on a first lateral side of the wedge and the second chamber located on a second lateral side of the wedge opposite the first lateral side of the wedge.
