20090122322 | INTERFEROMETRIC METHOD AND APPARATUS FOR LINEAR DETECTION OF MOTION FROM A SURFACE - An apparatus and a method for detecting surface motion of an object subject to ultrasound are disclosed. The method comprises generating a laser beam, dividing the laser beam into a reference beam and an object beam to be directed onto the surface, thereby producing a scattered object beam, introducing a frequency shift between the reference beam and the scattered object beam, wherein the frequency shift is smaller than the ultrasonic frequency, detecting the interference between the scattered object beam and the frequency shifted reference beam using a plurality of detecting elements to generate a plurality of electrical interference signals, wherein the electrical interference signals each comprise a wanted signal component indicative of the surface motion and a noise signal component, and processing the electrical interference signals to determine the surface motion of the object. | 05-14-2009 |

20150355141 | SIZE MARKER AND METHOD FOR CONTROLLING THE RESOLUTION OF AN ELECTROPHEROGRAM - The invention concerns a size marker for electrophoresis, characterized in that it contains several pairs of molecules the sizes of which are selected to allow the generation of a succession of double-peaks in one same electropherogram, said double-peaks being spaced apart two by two by a distance greater than the distance separating the two peaks of a double-peak. The invention also concerns a method for controlling the resolution of an electropherogram produced with a said marker. | 12-10-2015 |
