Title: Vector force sensor based on elastic surface waves.
Inventor: MEUNIER PAUL-LOUIS
IPC: G01L5/16
Filed: 1984-03-16
Abstract: The vector force sensor based on elastic surface waves, of the invention, comprises a mechanical member, a lamina 1 for example, subjected to a stress sigma . One face 9 of the lamina contains transducers 3 to 6, and 13 to 16 sustaining two elastic surface waves of perpendicular directions of polarisation S1 and S2 defining a reference trihedron Oxyz. Moreover, two magnetic means induce two orthogonal magnetic fields in the lamina along two axes of the trihedron Oxyz. Means enable the influence of the magnetic field on the speeds of propagation of the two elastic surface waves to be measured. Such a system is usable in particular in accelerometers.

Title: Beam-splitter with optically symmetrical structure
Inventor: SPENCER GORDON R
IPC: G02B27/02
Filed: 1984-07-16
Abstract: A semitransparent film of light reflective material is sandwiched between two optical plates of transparent materials. The plates have respective thicknesses and indices of refraction suitable for providing equivalent optical paths on either side of the film. The beamsplitter is located symmetrically between two image sources such that the light rays emanating from one source and reflected by the beamsplitter together with corresponding light rays emanating from the other source and transmitted by the beamsplitter combine and travel common paths from the film. An observer's eye or any similar focussing system can be positioned over a relatively large range of viewing angles to receive the combined light rays and produce a composite image.
