  • Patent number: 7431458
    Abstract: Method and arrangement for performing measurements of the topography of a surface (20), such as topography of an eye surface (20), wherein projecting means (1, 12) for projecting an image onto said surface (20) comprises a projection light source (1), and wherein at least a fraction of light leaving the surface (20) as a result of said projection is received using one or more receiving units (31, 32), such as charged coupled device (CCD) based cameras. The topography of the surface (20) is determined by analysis of said fraction of light leaving the surface (20), due to thermal emission and the image projected onto the surface (20) is projected with light comprising a colour for which the surface (20) is opaque, such as infrared light.

  • Patent number: 7422321
    Abstract: An eyewear structure combinable with an accessory glasses unit comprises a main glasses unit and an accessory glasses unit each having assembly bores drilled at a bridge thereon wherein attracting elements with insert grooves and attracted elements with insert rod are respectively combined with magnetic elements and embedded to the assembly bores of the main and accessory glasses units. Via the magnetism generated by the magnetic elements, the attracting and attracted elements can be magnetically attached to one another to obtain magnetic and insert positioning effects so that the accessory glasses unit can be stably clipped onto the main glasses unit thereby. Besides, each glass of the main glasses unit has a restricting hole drilled thereon to fit to a restricting protrusion of a temple hinge so that the temple hinge can be firmly located onto the glass and restrained in movement, facilitating easy and fast assembly and manufacturing thereby.

  • Patent number: 7375874
    Abstract: Described are MEMS mirror arrays monolithically integrated with CMOS control electronics. The MEMS arrays include polysilicon or polysilicon-germanium components that are mechanically superior to metals used in other MEMS applications, but that require process temperatures not compatible with conventional CMOS technologies. CMOS circuits used with the polysilicon or polysilicon-germanium MEMS structures use interconnect materials that can withstand the high temperatures used during MEMS fabrication. These interconnect materials include doped polysilicon, polycides, and tungsten metal.

  • Patent number: 7370960
    Abstract: This invention provides binocular eyeglasses that have linear polarizing lenses to be employed by a golfer to examine the surface of a putting green as an aid in deciding the speed and direction of a puffing stroke. The planes of maximum transmission for the lenses are preferably complementary each lens 45° to horizontal. The polarizing lenses are supported to permit the golfer to rotate the lenses to “tip-up” position out of the line of sight, which enables the golfer to alternatively see a direct view and a polarizer altered view of the putting surface without significant delay of play.

  • Patent number: 7370966
    Abstract: The ophthalmologic apparatus 1 splits low coherence light LO into a signal light LS and a reference light LR, the interference light LC being generated by having the signal light LS overlap with the reference light LR, and detects this interference light LC. In addition, the apparatus comprises an optical alignment system 190A for performing the alignment of an optical system forming the signal light path to the eye E. An intraocular distance calculator 214 determines the distance between the position where the signal light LS has been introduced onto the eye E and the position where the signal light LS has been reflected by the fundus oculi E based on length of the optical path of the signal light, the length of the optical path of the reference signal light, the working distance after alignment, and the detection signal output by the CCD 184 (or signal intensity data).
