  • Publication number: 20230201037
    Abstract: An ophthalmic laser system for generating a first beam at a first wavelength on a first beam path and a second beam at a second wavelength on a second beam path, and directing optics to selectively direct the first beam or the second beam to a treatment beam path. The ophthalmic laser system incorporates a reflex coaxial illuminator comprising a reflex mirror movable on an axis from a position out of the treatment beam path to a position in the treatment beam path to direct illumination into an illumination path coaxial with the treatment beam path. The reflex mirror is adapted to transmit a beam that follows the second beam path.

  • Patent number: 7312557
    Abstract: An apparatus for generating an electrical power upon an acceleration of the apparatus is provided. The apparatus including: a piezoelectric member having at least a portion thereof formed of a piezoelectric material; and a mass-spring unit having a spring element attached to the piezoelectric material and configured to compress and/or elongate within a predetermined limit, the mass-spring unit further having a mass offset from the piezoelectric material; wherein the mass-spring unit is configured to vibrate within the predetermined limit, upon the acceleration of the apparatus, the vibration applying a cyclic force to the piezoelectric member to generate an output power from the piezoelectric member.
