    摘要： A method for implementing a logic operation employs an all fluid-based no-moving part micro-mechanical logic family of microfluidic bubble logic devices that are constructed from complex sequences of microfluidic channels, microfluidic bubble modulators for programming the devices, and microfluidic droplet/bubble memory elements for chemical storage and retrieval. The input is a sequence of bubbles/droplets encoding information, with the output being another sequence of bubbles/droplets. For performing a set of reactions/tasks, the modulators program the device by producing a precisely timed sequence of bubbles/droplets, resulting in a cascade of logic operations within the microfluidic channel sequence, utilizing the generated bubbles as a control. The devices are based on the principle of minimum energy interfaces formed between the two fluid phases enclosed inside precise channel geometries. Various devices, including logic gates, non-volatile bistable memory, shift registers, multiplexers, and ring oscillators have been designed and fabricated.

    摘要： Disclosed herein in a MULTI-AND fluid logic circuit comprising essentially of a conventional fluid amplifier having a power source, first and second control channels and first and second output channels. The amplifier is provided with biasing means which is associated with one of the control channels and means are associated with the other control channel for producing a control signal which is a function of a predetermined number of external signals. More particularly, this last named means comprises a plurality of aspirators, each having an input nozzle and an exhaust nozzle and each connected to an enclosed manifold which in turn is in fluid communication with the second control channel of the fluid amplifier. The operation is such that the simultaneous presence of a fluid signal in all aspirators creates a sufficient pressure change to switch the fluid stream in the fluid amplifier from the first output channel to the second output channel.

    摘要： The invention relates to a fluidic device comprising a channel of rectangular section having a rectangular inlet orifice in one of the walls and a rectangular outlet orifice in the opposite wall; the channel acts as a vent. When fluid enters the channel through the inlet orifice, an unrestrained and irreversible expansion takes place. The expansion is accompanied by variation in local pressure due to the interaction of multiple expansion and compression waves which provide the device with a desired input/output pressure characteristic.
