  • Patent number: 6424858
    Abstract: An electronic imaging apparatus for transillumination and visually exposing vasculature of the human anatomy by passing infrared light through the portion of the anatomy to be studied and receiving infrared light which passes through the flesh and bone. By receiving only infrared light which is passed through the body, a real time image of the vasculature may be visualized as infrared light does not pass through blood filled organs, namely, veins, arteries and capillaries. A method is disclosed which describes the steps of placing the human anatomy to be studied adjacent a light source, receiving infrared light which passes through the anatomy and visualizing the resultant image of the human vasculature.

  • Patent number: 5504572
    Abstract: An electronic imaging apparatus is provided which has means for detecting the presence of internal structure in an opaque or translucent object. The apparatus has a light source directing a beam of light towards the object from one side and a light receiver on another side thereof to convert invisible light passing through the object into a visible image. Means to record the image produced is made available as well as means to produce a three dimensional image or drawing.

  • Patent number: 5154710
    Abstract: An ophthalmic device (10, 30, 50, 81) in the form of a cup (11, 31, 51) having a periphery (12, 32, 52, 85) substantially scaphoid in plan for contacting a facial region in the vicinity of an eye. The interior of the cup is accessible from its exterior by way of at least a first port (14, 34, 58, 86) and a second port (15, 35, 60, 87). The first port (14, 34, 58, 86) provides an inlet for a dispensing unit (17, 38, 63) for material to be supplied to the eye. The second port (15, 35, 60, 87) provides a target for viewing by an eye about which the periphery (12, 32, 52, 85) is disposed. The device (10, 30, 50, 81) is preferably fabricated from a material which is substantially opaque or imperfectly transparent and the second port (15, 35, 60, 87) is an aperture which provides a viewing target for an eye with which the device is being used. Alternatively the device can be in the form of a transparent shell with a distinctive target supported on the shell.

  • Patent number: 4652794
    Abstract: An electroluminescent device has an active electroluminescent layer 3 backed by a resistive layer 4 formed of an amorphous chalcogenide glass. The amorphous chalcogenide glass may comprise germanium, arsenic and/or antimony and selenium. The device comprises a glass base 1 on which there is supported a patterned transparent electrically conducting layer 2, the active luminescent layer 3, the amorphous chalcogenide glass backing layer 4, an optional dielectric layer 5 and an electrode 6. When an operating voltage is applied between layer 2 and electrode 6 the pattern in layer 2 becomes visible through base layer 1 and the contrast of the pattern is enhanced by the dark background produced by the backing layer 4.
