  • Patent number: 6490085
    Abstract: A symmetric relay system for endoscopes includes an optically-aligned pair of elongated concavo-convex rod-type lenses formed from crown glass, to the convex end surface of each of which a meniscus-shaped flint lens is cemented. The concave ends of the rod lenses are disposed to face the intermediate images of the relay system, and the convex ends to face the aperture of the relay system. A pair of achromatic lenses, each formed of a pair of lens elements x, y, are disposed adjacent and in optical alignment with the respective concave ends of the rod lenses between the concave rod ends and the intermediate images. Each achromatic lens fulfills the condition n x/ny=vx/vy. Apochromatic glass combinations may be used in the rod lenses to significantly reduce the secondary spectrum.

  • Patent number: 6471662
    Abstract: An acoustic therapy device is provided including a housing, an electro-acoustic transducer, a coupling element and coupling cushions. The electro-acoustic transducer is arranged in the housing which includes a shell. The coupling element has a coupling surface flush with edges of the shell. Another coupling surface of the coupling element is on the sound irradiation surface of the transducer and sound waves from the sound irradiation surface are directly coupled into the coupling element. An elastic coupling cushion is connected to a surface of the coupling element. One coupling surface of the coupling element and an exterior coupling surface of the coupling cushion define a sound advance path the length of which may, along with a penetration depth of the sound waves, be varied.
