| 20110220706 | SECURE MAILING ENVELOPE AND METHOD FOR MANUFACTURING ENVELOPE - A mailing envelope is disclosed, the envelope including an outer paper layer forming a pocket and an inner foil layer lining an inner surface of the outer paper layer within the pocket. The foil layer includes an aluminium foil having a thickness in a range of 6 to 10 μm. Also disclosed is a mailing envelope including an outer paper layer forming a pocket and an inner foil layer lining an inner surface of the outer paper layer within the pocket, wherein the inner foil layer includes an aluminium foil coated with a lacquer. | 09-15-2011 |

| 20110228380 | NON-LINEAR OPTICAL DEVICE - A non-linear optical device includes a frequency-conversion waveguide and first and second input waveguides. The longitudinal axes of the input waveguides are inclined to that of the frequency-conversion waveguide such a first transverse mode is excited in the latter at the input frequency in operation of the device. The frequency-conversion waveguide supports a second transverse mode at an output frequency of the device, such that the phase velocity of the second transverse mode at the output frequency is substantially equal to that of the first transverse mode at the input frequency, thus providing phase-matching by balancing the effects of chromatic and modal dispersion. | 09-22-2011 |

| 20100148093 | COVERT ILLUMINATION - This invention relates to methods and apparatus for covert illumination. The method involves illuminating the scene with light which is tuned to an absorption resonances of atmospheric oxygen gas. Light tuned to have a wavelength corresponding to an oxygen absorption wavelength travelling through the atmosphere is therefore attenuated by absorption. The method therefore teaches that a low power illumination source can be used to illuminate nearby objects, thus allowing the detail thereof to be resolved, and the illuminating light reflected from the object, or even the light source itself, will be undetectable beyond a certain range due to atmospheric absorption. The illumination may be used in conjunction with the use of low light level imagers to image a scene. Alternatively the illumination could be used for short range optical communication which will be undetectable at much longer range. | 06-17-2010 |
| 20100329289 | METHOD AND APPARATUS FOR GENERATING OPTICAL BEATS - Apparatus comprising an optical fibre laser having at least two laser cores and means arranged to combine laser output from the at least two laser cores at a first end of the optical fibre laser to produce a combined laser output having one or more beat signals. | 12-30-2010 |
