  • Skin contact reduction device for eyewear and other human ear and temple resting equipment
    Patent number: 10261339
    Abstract: Embodiments of a skin contact reduction device that is substantially spherically shaped and attaches to the temple portion of facial equipment that goes over the ear or alongside the wearer's face. The device is directionally positioned with a larger opening pointing towards the front of the wearer's face and a smaller opening towards the rear. Both the larger front opening and interior of the device are significantly larger than the width of the temple portion of the facial equipment and therefore the device does not compress or stiffen when installed. The smaller rear opening of the device resiliently grips the temple portion of the facial equipment. Once attached, the device is adjusted by the wearer to a preferred position to keep a wearer's equipment on their face while minimizing contact and pressure between the temple or ear portion of the equipment frame and the wearer's head.

  • Method and apparatus for remote imaging
    Patent number: 10261297
    Abstract: A remote imaging apparatus, and corresponding method, includes a hyperbolic primary mirror that receives light from a remote object to be imaged. The primary mirror has a continuous surface that reflects, at least twice, the light from the remote object. The apparatus also includes a hyperbolic secondary mirror having a continuous surface that reflects, at least twice, the light from the remote object. The secondary mirror delivers the light to a field corrector via a port of the hyperbolic primary mirror, and the field corrector is configured to correct for an optical aberration of one or both of the hyperbolic primary and secondary mirrors. Embodiments can provide low distortion, small aspect ratios, and small form factors and moments of inertia for fleets satellite-based and other imaging systems.

  • Hand held or eyeglass clip on dark adaption tester
    Patent number: 10251542
    Abstract: This device consists of a frame and light filters so as to enable a highly portable device to measure Dark Adaption. Dark Adaption is a process which tests sight in low light conditions and is an indicator of wet AMD disease, the leading cause of blindness in older people. This testing process was first established by the Goldmann-Weekers machine in the 1950s. The portability is achieved by use of filters, a common means to light reduction, and elimination of a machine outer cover. The simplicity and portability of this invention allows many types of very substantial cost efficiencies in eye examinations and also greater flexibility. With this device, testing for incipient wet AMD may be achieved in routine eye examinations where it is not now common. Home testing for wet AMD is also made possible and practical with this device.

  • Lens unit
    Patent number: 8014082
    Abstract: One end of an FPC (21) for supplying power to the driving section of a light amount control section provided in a shutter unit (20) is disposed between a second lens holder (17) and the shutter unit (20) secured to this second lens holder (17) and is held between the second lens holder (17) and the shutter unit (20). Thus, the FPC (21) is prevented from being spaced apart from the shutter unit (20), and a member for securing the FPC (21) to the shutter unit (20) is eliminated, reducing the number of part items. Further, the second lens holder (17) and the shutter unit (20) blocks unwanted light toward the FPC (21), so that a ghost image is prevented from appearing on an image due to unwanted light reflected on the FPC (21).
