  • IMPACT ATTENUATOR SYSTEM
    Publication number: 20070286675
    Abstract: An impact attenuator system includes a hyperelastic member that comprises an energy absorbing material which behaves in a rate-independent hyperelastic manner so that its permanent set is minimized and the material can absorb tremendous amounts of impact energy while remaining fully recoverable.
    Type: Application
    Filed: December 6, 2006
    Publication date: December 13, 2007

  • Optical device comprising a holder accommodating an optical system which compensates for thermal expansion/contraction
    Patent number: 4855987
    Abstract: An optical system is described, for example a radiation source unit (10) supplying a collimated radiation beam (RB), comprising a tubular holder (30) a radiation source (33) arranged in the holder and an optical system having a collimator lens (37). The displacement of the focus of the optical system caused by the variation in length of the holder occurring at a varying temperature can be compensated by a suitable choice of notably the geometry (R.sub.1, D.sub.1) and the refractive index (n.sub.1) of the collimator lens.

  • Fiber optic plate
    Patent number: 4247165
    Abstract: In order to prevent a fiber optic window from acting as an optical diffraction grating, the window is provided with means which disturb phase relationships in incident light. A solution which does not have an adverse effect on the quality of the window is in that the fibers do not extend along straight connecting lines between the end faces. Moreover, at least one of the end faces may be provided with a frosted surface structure.
