Title: Waveguide Structure
Inventor: SAMUEL DAVIES
IPC: H01S5/0625
Filed: 2017-09-29
Abstract: The waveguide structure comprises a plurality of layers which are, in order: a substrate, 806, a sacrificial layer, 805, a lower cladding layer, 803, a waveguide core layer, 802, and an upper cladding layer, 801. A waveguide core, 804, is formed from the upper & lower cladding layer and the waveguide core layer. The waveguide structure has a continuous channel (or trench, via), 807, passing through the upper cladding layer, waveguide core layer, and lower cladding layer and running parallel to the waveguide core along substantially the whole length of the thermally controllable section. The waveguide structure also has a thermally insulating region in the sacrificial layer extending at least from the channel to beyond the waveguide core along the whole length of the thermally controllable section (as shown by 308 in Figure 5.) The sacrificial layer comprises a sacrificial material outside of the thermally insulating region, and a thermally insulating gap or thermally insulating material separating the lower cladding layer and substrate inside the thermally insulating region. The structure is manufactured by providing a wet etch to the sacrificial layer through the channel in order to remove material from at least the thermally insulating region.

The space may have a quarter-wave resonant frequency below the pass-band of the first driver and be bounded radially by the magnet structure of the second driver to define: an annular space; a space concentric around the first driver; or a space with varying radius. The sound-absorbent material may be supported on outwardly-projecting fingers on a former that is fitted to, or around, the first driver and the material may comprise one of: acoustic foam, fabric; open-cell foam; and closed-cell foam. In a second aspect of the invention the first driver is located within the cavity formed by the voice coil of the second driver.

Title: Seal assembly
Inventor: BO GAO
IPC: H02G15/013
Filed: 2017-11-28
Abstract: A sealing assembly comprises a housing 100 with a hole to allow an elongated element 10 to pass through, a rubber sealing sleeve 400 to be sleeved on the elongated element 10 and a metal sealing cover 200 to be sleeved on the rubber sleeve 400 and to be connected to the housing 100. The metal cover 200 presses the rubber sleeve 400 so that the rubber sleeve 400 is elastically deformed and seals a mating interface between the elongated element 10 and the hole. The seal assembly further includes a plastic bushing 300 between the metal cover 200 and the rubber sleeve 400 so as to physically isolate the metal cover 200 from the rubber sleeve 400. Thereby, the metal cover 200 does not directly contact the rubber sleeve 400, effectively avoiding the rubber sleeve 400 from being worn or damaged when being pressed by the metal cover 200.

Title: Waveguide and method for fabricating a waveguide
Inventor: STEPHEN PAUL MASON
IPC: G02B27/42
Filed: 2019-09-06
Abstract: A method for fabricating a waveguide or light guide comprising fabricating two master grating tools with different grating profiles over their surfaces (fig 4a) and using these tools to replicate the grating profiles over the full surface of two substrates (fig 4b). The method further comprises applying a dielectric layer over a selected area of the two substrates (fig 4c, 240 and 245). Finally, the method comprises joining the two substrates together with their dielectric surfaces 260, 255 facing one another and a lamination 250 layer between them. As the lamination layer has the same refractive properties as the substrates the areas of the grating without a dielectric layer applied do not have a significant diffractive effect. The areas of the grating where the dielectric has been applied have a much higher diffractive efficiency. There is also a claim to a waveguide made using this method.

Filed: 2019-10-09
Abstract: A method for de-blending seismic data associated with an interface located in a subsurface of the earth, includes receiving 700 blended seismic data E generated by firing N source arrays according to a pre-determined sequence Seq. The sequence may modify a firing parameter such as time delay, amplitude or phase. N sub-datasets SDn are selected 702 from the blended seismic data E. The datasets may be selected such that the intersection of any two datasets is zero and the union of all the datasets is the blended data E. Each selected sub-dataset SDn is interpolated 704 to reference positions ref, where the blended seismic data E is expected to be recorded, to generate interpolated data k. The interpolated data k is deblended 706 to generate de-blended data o. An image of the interface of the subsurface is generated 708 based on the deblended data o. Deblending may be firstly performed for low frequencies.
