Complementary fluidic valves and logic gates

A fluidic logic-gate system comprising:

• a plurality of inlet ports, a first input port and a second input port, and an output port;
• a high-pressure source;
• a low-pressure source;
• a first input source connected to the first input port;
• a second input source connected to the second input port;
• a plurality of fluid channels each configured to route fluid from one of the plurality of inlet ports to the output port;
• two or more pistons each comprising:
• opposing restricting gate transmission elements each configured to block a different one of the plurality of fluid channels;
• a first controlling gate transmission element configured to interface with a first control pressure that, when applied to the first controlling gate transmission element, forces the piston towards a first position;
• and
• a second controlling gate transmission element configured to interface with a second control pressure that, when applied to the second controlling gate transmission element, forces the piston towards a second position.

A fluidic valve comprising:

• an inlet port, an additional inlet port, a control port, an additional control port, a third control port, and an outlet port;
• a fluid channel configured to convey fluid from the inlet port to the outlet port;
• an additional fluid channel configured to convey fluid from the additional inlet port to the outlet port;
• and
• a piston comprising:
• a restricting gate transmission element configured to:
• block, when the piston is in a blocking position, the fluid channel;
• and
• unblock, when the piston is in an additional blocking position or an unblocking position, the fluid channel;
• an additional restricting gate transmission element configured to:
• block, when the piston is in the additional blocking position, the additional fluid channel;
• and
• unblock, when the piston is in the blocking position or the unblocking position, the additional fluid channel;
• a controlling gate transmission element configured to interface with a control pressure from the control port, wherein the control pressure, when applied to the controlling gate transmission element, forces the piston towards the blocking position;
• an additional controlling gate transmission element configured to interface with an additional control pressure from the additional control port, wherein the additional control pressure, when applied to the additional controlling gate transmission element, forces the piston towards the additional blocking position;
• and
• a third controlling gate transmission element configured to interface with a third control pressure from the third control port, wherein the third control pressure, when applied to the third controlling gate transmission element, forces the piston towards the additional blocking position.
