Abstract: Local strain and optionally other properties of an optical sensing fiber are detected as a function of position along the optical sensing fiber. A light pulse with a plurality of simultaneous laser modes at mutually different wavelengths is transmitted into the optical sensing fiber. Light produced by backscattering of the light pulse in the optical fiber is fed to a multi-way coupler, via a first and second optical path with different optical path lengths. Intensities of different phase combinations of light from the paths are detected by detectors at the outputs of the multiway coupler. A data processing system computes relative phase values of light from the first and second paths for a series to time points with time delays corresponding to scattering at different positions along the fiber. In an embodiment, inelastically scattered light such as due to Brillouin scattering and/or Raman scattered light is selective passed to the detectors and detected.

Abstract: A conformable matrix display device is provided with row conductors on the conformable carrier, each for a respective row of the matrix of pixel circuits. Each row conductor has serpentine trajectories in spaces between the pixel circuits in the respective row. Power supply voltage and selection pulse signals are transmitted over the same row conductors. Each row conductor is connected to supply voltage and selection inputs of the pixel circuits in the respective row. Each pixel circuit has a pulse transmission circuit coupled between the selection input and the control input of a de-multiplexing circuit for de-multiplexing data signals on column conductors. In this way the power supply voltage and the selection signal can be supplied making shared use of space between the pixel circuits. Thus the number of conductors in the matrix display device is reduced, which enables a greater distance between the conductors and/or bends in the conductors, which makes the circuit more stretchable and/or bendable.
