Neuronal signaling. To support the general function of the nervous system, neurons have evolved unique capabilities for intracellular signaling (communication within the cell) and intercellular signaling (communication between cells).
Because of this, gyroscopes are useful for measuring or maintaining orientation. Invention History. The gyroscope was invented in 1852 by the French experimental physicist Leon Foucault (1819-1868) as part of a two-pronged investigation of the rotation of the earth.
On February 21, 1893, a patent was issued for the system that governed the intermittent movement of film in the Kinetograph. However, Robinson (1997) misleadingly stated that patents for the Kinetograph camera and the Kinetoscope viewer were finally issued in early 1893 (p. 38).
