  • Publication number: 20160074321
    Abstract: The present invention is directed to an ophthalmic composition, method for preparing the same, and use of the same. The ophthalmic composition includes a mixture of lipid nano-dispersion and gel substrate, wherein the lipid nano-dispersion includes a first lipid, a second lipid, and emulsifier; in which the first lipid exists in form of solid lipid as staring material, and the second lipid exists in form of liquid lipid as staring material. The ophthalmic composition can better reduce the symptoms of dry eye, and is safe, convenient and economical to use, and can be used during daytime without blocking of vision.

  • Patent number: 8349004
    Abstract: A set formed of a scleral buckle and an encircling band is provided for use in connection with retinal detachment surgery to enable the implantation of both the scleral buckle and encircling band free of any suture. A self-assembling scleral buckle-encircling band combination is secured in place by surface scleral tunnels operative as belt loops to enable the securing of a scleral buckle and encircling band on the eyeball to exert an intended indentation effect for treatment of retinal detachment.

  • Patent number: 7289701
    Abstract: A platform for converting a signal between optical and electrical form and vice versa is provided. The platform includes a dielectric mount, a semiconductor light source and optical fibers. Some of these components are fabricated separately and then brought together in an integrated assembly together with a focusing lens. The platform permits the self-alignment of the optical fibers in a flip-chip vertical cavity surface emitting laser (VCSEL) array module package. The self-alignment of the optical fibers is achieved by the engineering of the geometrical dimensions of the platform. The techniques may be used to form large-scale integrated opto-electronic circuits and switching networks.

  • Patent number: 7010230
    Abstract: A novel integrated multiple-rate optical time division multiplexing (OTDM) module is disclosed. An integrated set of modulators generates optical RZ signal streams which are then time-delayed by a set of integrated optical delay switching and combining arrays and interleaved to produce an OTDM signal. The integrated optical delay switching and combining arrays are adapted to be controllably set to various delays to facilitate interleaving of many possible bit-rates. Such an approach alleviates stability problems offered by conventional fiber-based OTDM technology, increases flexibility, aids in reducing the size, complexity, and cost. Furthermore, the OTDM chip of the present invention offers fine tuning capabilities thereby allowing for slight adjustments in the interleaving of optical signal streams if needed. The present invention also provides for the integration of an optical pulse source chip and a multiple-rate OTDM chip onto a single substrate or platform using hybrid packaging technology.
