| 20090028074 | Antenna feed network for full duplex communication - The present invention provides a wireless device for effecting two way wireless transmission, an antenna feed network ( | 01-29-2009 |
| 20090268642 | High isolation signal routing assembly for full duplex communication - A signal routing assembly accepts a first transmission signal at an input and outputs a substantial portion of the signal at a common port of the signal routing assembly. A second transmission signal is received at the common port and is routed through the signal routing assembly delivered to output of the signal routing assembly. Leakage signals from routing devices leaking the first transmission signal are terminated inside the signal routing assembly. Leakage signal from a divider/combiner are cancelled by reflect signal from at least one reflector device. A transmitter produces the first transmission signal and the signal routing assembly delivers this signal to the common port of the signal routing assembly. In full duplex operation, second transmission signals received at the common port are routed to the output to be applied to a receiver. | 10-29-2009 |
| 20090274072 | Antenna feed network for full duplex cummunication - The present invention provides a wireless device for effecting two way wireless transmission, an antenna feed network, and a patch antenna. The wireless device includes an antenna assembly having two inputs accepting two feed signals shifted a feed signal phase difference apart. The antenna assembly receives a radiated signal and produces first and second received signals. First and second reflected feed signals are also produced at the two antenna inputs. A transmitter produces a transmission signal and a receiver receives the radiated signal while the transmission signal is transmitted by the antenna assembly. The antenna feed network interconnects the transmitter port, the receiver port, and the antenna assembly and produces the received signal while effecting substantial cancellation of the first and second reflected feed signals. Additionally, or alternatively, first and second transmission leakage signals at the received signal output substantially cancel each other. | 11-05-2009 |

| 20090005764 | Method for Modifying the Refractive Index of Ocular Tissues - A method for modifying the refractive index of ocular tissues. The method comprises irradiating select regions of ocular tissue with a visible or near-IR laser. The irradiation results in the formation of structures in the ocular tissue, characterized by a change in refractive index, and which exhibit little or no scattering loss. | 01-01-2009 |
| 20090143858 | OPTICAL MATERIAL AND METHOD FOR MODIFYING THE REFRACTIVE INDEX - A method for modifying the refractive index of an optical, polymeric material. The method comprises irradiating select regions of the optical, polymeric material with a focused, visible or near-IR laser having a pulse energy from 0.05 nJ to 1000 nJ. The irradiation results in the formation of refractive optical structures, characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material. The method can be used to modify the refractive index of an intraocular lens following the surgical implantation of the intraocular lens in a human eye. The invention is also directed to an optical device comprising refractive optical structures, wherein the refractive structures are characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material. | 06-04-2009 |
| 20090287306 | Optical hydrogel material with photosensitizer and method for modifying the refractive index - A method for modifying the refractive index of an optical, hydrogel polymeric material. The method comprises irradiating predetermined regions of an optical, polymeric material with a laser to form refractive structures. To facilitate the formation of the refractive structures the optical, hydrogel polymeric material comprises a photosensitizer. The presence of the photosensitizer permits one to set a scan rate to a value that is at least fifty times greater than a scan rate without the photosensitizer in the material, yet provides similar refractive structures in terms of the observed change in refractive index. Alternatively, the photosensitizer in the polymeric material permits one to set an average laser power to a value that is at least two times less than an average laser power without the photosensitizer in the material, yet provide similar refractive structures. | 11-19-2009 |
| 20100298688 | PHOTOACOUSTIC IMAGING USING A VERSATILE ACOUSTIC LENS - To image various soft tissues in the body using pulsed laser optical excitation delivered through a multi-mode optical fiber to create photoacoustic impulses, and then image the generated photoacoustic impulses with an acoustic detector array, a probe includes either a mirror and an acoustic lens or a special acoustic lens of variable focal length and magnification that can operate in a liquid environment that is aberration-corrected to a sufficient degree that high resolution images can be obtained with lateral as well as depth resolution. | 11-25-2010 |
| 20100298933 | Optical Material and Method for Modifying the Refractive Index - The invention is directed to an optical device comprising refractive optical structures, wherein the refractive structures are characterized by a change in refractive index, exhibit little or no scattering loss, and exhibit no significant differences in the Raman spectrum with respect to the non-irradiated optical, polymeric material. | 11-25-2010 |
| 20110071509 | METHOD FOR MODIFYING THE REFRACTIVE INDEX OF OCULAR TISSUES - A method for providing vision correction to a patient. The method includes: (a) measuring the degree of vision correction needed by the patient and determining the location and shape of refractive structures that need to be positioned within the cornea to partially correct a patient's vision; (b) directing and focusing femtosecond laser pulses in the blue spectral region within the cornea at an intensity high enough to change the refractive index of the cornea within a focal region, but not high enough to damage the cornea or to affect cornea tissue outside of the focal region; and (c) scanning the laser pulses across a volume of the cornea or the lens to provide the focal region with refractive structures in the cornea or the lens. Again, the refractive structures are characterized by a change in refractive index, and exhibit little or no scattering loss. | 03-24-2011 |
