Patent CA-2458176-A1 (CA)
Inventor: STERNICKEL KARSTEN
IPC: G06K9/00
Filed: 2002-09-20
Abstract: A two-part method for reducing the noise contribution in a composite signal using the wavelet transform is described. The procedure involves the identification of subspaces in the reconstructed state space created by dynamical processes ( either by deterministic noise or the signal itself), t he separation of different subspaces and the separation of subspaces from stochastic noise. The method is used for non-linear de-noising (NLD) of magnetocardiograph or electrocardiograph time series signals by performing local projections in the reconstructed state space using the wavelet transfo rm to identify and describe deterministic structures. Subspaces generated by an y deterministic process are located and separated independently of its source.

Patent CA-2468758-A1 (CA)
Inventor: BERGOUGNOU MAURICE
IPC: B05C19/02
Filed: 2002-11-29
Abstract: The invention concerns a method for coating an object with a film derived from melting a thin powder layer which consists in: (a) providing an electrically charged fluidized powder bed in a vessel, said powder being charged with a forced circulation tribocharging device; (b) wetting in the vessel the object connected to a zero potential or sufficient to coat it with powder; (c) placing the powder-coated object in an oven at an adequate temperature until the coating film is obtained by melting the powder. In accordance with an advantageous embodiment of the invention the oven comprises electrodes brought to a high electrical potential so as to produce a corona effect which compensates relaxation of the charge of powder particles when heated. Thus, the charge of the particles is maintained and hence remain on the object and can thus form the film by melting. The invention also concerns the equipment for implementing the method.
