Microfluidic Passive Flowmeters of Liquids and Gaseous or Friable Substances The measured quantity is vortical MF, caused by the electrogaseodynamical jet, of gasiform stream for the toroidal pickup coil (PC)

Microfluidic Passive Flowmeters of Liquids and Gaseous or Friable Substances The measured quantity is variation of the surrounding (natural) MF according to the magnetohydrodynamical (MGD) effect for the solenoidal PC.

Microfluidic Passive Flowmeters of Liquids and Gaseous or Friable Substances Measured MF interferes with the surrounding one. The variations of measured MF strength H fl 1 of the stream or flow as a result of subtraction: H fl =H p -H o

Microfluidic Passive Flowmeters of Liquids and Gaseous or Friable Substances By employing some substance as a core of PC is expected to define an effective magnetic permeabillity  ef of the formed physical body. The quantative content of hemoglobinum is defined by the difference between an induction sensor's output voltages U o - for a typical its value in some organism which is placed in the ambient permanent MF and U x which has been measured for the investigated organism.

Superconducting Room-Temperature Micro-Nanoscope

A Solid-State Electromagnetic (Optical) Transistor The current state of a problem: ◊ semiconducting transistors- limited carrier speed (frequency) and presence of the fluctuations (noises); ◊ magnetic amplifiers- distortion of a signal during motion of the ferromagnetic domains; ◊ optical transistor- application of parallel mirrors (lenses) and filling of the space between them by the special liquid.

A Solid-State Electromagnetic (Optical) Transistor The results of an innovation: ▪ increasing of fast-acting (frequency) to the maximal possibly; ▪ dramatically reduce the noise level as a result of non-hysteresis operation (without internal transformation of material’s structure); ▪ improving of a manufacturability of the device due to the presence of single solid-state working body.
