Patent CA-2286082-A1 (CA)
Inventor: WIEDEMANN GUENTER
IPC: B23K26/00
Filed: 1998-04-09
Abstract: The invention relates to a method for producing nonslip floor coverings (1) made from mineral materials such as natural stone, fine stoneware, artificial stone or ceramics. The inventive method is carried out in two stages. In the first stage, micro-craters which are invisible to the human eye are created and statistically distributed on the surface of the floor coverings or slabs by means of pulsed laser bombardment. According to the invention, the surface of the floor coverings or slabs thus obtained are subsequently subjected to hydromechanical post-treatment, wherein the surface of the laser-structured floor covering or slabs are sprayed at least twice with a liquid (3, 8) e.g. inorganic acid or halogen hydrogen acid. The final spray process (8) is used to clean and/or neutralize previous spray liquids from the surface of the floor covering (1) or slabs. After each spray process, at least one further process occurs wherein the spray liquid is distributed homogeneously on the surface of the floor coverings or slabs and excess spray liquid is removed (12) from this surface. Subsequently, at least one drying process (13) is carried out.

IPC: B01D63/02
Filed: 1998-05-12
Abstract: Process of forming compact, high flux, fouling resistant gas filters by coating continuous ultra thin layer of non-porous gas permeable polymer over filter surface by contacting one side of microporous substrate with dilute coating solution of polymer, preferably amorphous copolymer of perfluoro-2,2-dimethyl-1,3-dioxole, which is hydrophobic and oleophobic. Substrate pore size filters polymer from solution as solvent flows through, leaving ultra thin layer of polymer. Residual solvent evaporated off. Process useful to coat sheet and hollow fiber substrates, particularly multiple hollow fibers assembled in modules. Coating prevents solid particles and liquid droplets from blocking flow through gas filter, which is also easily cleaned and reusable. The coated fiber modules are useful as high flow rate gas filters, including collecting suspended droplets, filtering air for microelectronic assembly plants and filtering atmosphere in biomedical clean rooms.

Abstract: An acoustic coupler adapted for use with an intracanal receiver module can be deeply inserted into the ear canal of the user while making minimal contact with the walls of the ear canal. The minimal contact feature of the invention allows the acoustic coupler to seal the ear canal acoustically and anchor a hearing device at an optimal depth within the ear canal, while maximizing the user's comfort. The acoustic coupler is manufactured from a soft, pliable elastomer that allows it to conform readily to the shape of the ear canal. The acoustic coupler incorporates structural supports that allow the coupler to maintain an acoustical seal and withstand the inward pressure of the ear canal wall while making minimal contact with the ear canal. The invention incorporates a cerumen-protecting feature that prevents damage to a hearing device from infiltration of earwax into the sound port of the receiver. A vent pathway for control of occlusion effects is also provided. A user-friendly, attachment mechanism incorporating a snap-on, twist-off feature allows the acoustic coupler to concentrically surround the receiver module within the ear canal in a space-efficient manner.

Title: Embedding supplemental data in an encoded signal
Inventor: KAMPERMAN FRANCISCUS L A J
IPC: H04N21/2362
Filed: 2000-01-10
Abstract: There are two different methods of embedding supplemental data, e.g. for watermarking into an encoded signal. I) For an encoder, requiring auxiliary information for encoding (=probability information here), the auxiliary information to encode the supplemental data is derived from other data used in the encoding process. Thus the derived auxiliary data needs not be stored, which makes embedding economical in terms of bit amount. II) In the encoding process used for super Audio CD, a set of parameters (e.g. filter coefficients) is used by the encoder, whereby these parameters have to be stored, as they are needed for decoding. To embed supplemental data, at least one of the chosen parameters (e.g. the LSB of the first coefficient) is set to a dedicated value in response to the value of the supplemental data to be embedded. Thus the bit rate will not be affected at all.
