Many factors contribute to the minimum input laser power required to achieve pulse visualization in optical fibers, and the methods herein will not always be suitable for every application. These factors include: number of scattering sites within the optical fiber under test; standoff distance to fi...
It would also be possible to use measurements of blood pressure taken elsewhere, however, such as in the pulmonary artery on the right side, although such sites may require invasive intracardiac measurement. Moreover, another embodiment of the invention is described below in which the (or another...
In the laboratory, Cai and collaborators Mohammad Taghinejad, Zihao Xu, Kyu-Tae Lee and Tianquan Lian created an array of tiny plasmonic gold triangles on the surface of a centrosymmetric TiO2slab. They then illuminated the TiO2/gold structure with a pulse of redlaserlight, which acted as an ...

Pulse wave measurements provide vital information in medical diagnosis. For this reason, a measurement system is developed for determining the transient time of the pulse wave between the heart and the ear. To detect pressure variations in the sealed ear

stress that shielding tensors are not the only motivation for developing and applying line-narrowing m.p. sequences. For instance, good use of m.p. sequences has been made inspin diffusionexperiments for selecting specific proton sites that give valuable information about the miscibility ofpolymer...
filament growth started at several initiation sites at once and continued growing at the same time. Figure3b–dshows the analysis of the crack widths of a typical shorted SC and HP sample using a focused ion beam-scanning electron microscope. In the SC sample sub-surface cracks with widths of...
Apparatus for measuring the oxygen saturation level of blood at an internal measurement site in a human or animal patient by reflectance pulse oximetry, comprising first and second light sources (5,10), a first optical fibre (30) for transferring light from at least one said light source to ...
