Title: Sealing sheet for use to close a container-defining sheet
Inventor: BOUTHIETTE MICHEL
IPC: A61J7/04
Filed: 2006-03-03
Abstract: Disclosed is an improved sealing sheet for use to close a container-defining sheet having a top surface comprising a given number of spaced apart cavities embossed therein, each of the cavities being upwardly opened and thus defining a container that is surrounded by a flange that is part of the top surface of the container-defining sheet. This improved sealing sheet has a top layer with tearing lines punched therein in such a manner and position as to extend from oen side of each cover piece that may be splitted from the sealing sheet to cover one of the cavities in line with opposite sides of a bottom piece left on the corresponding cover piece. Such facilitates peeling of the bottom piece and of the corresponding part of the cover piece from the corresponding container to have access to the element(s) stored in it while preventing glue to be left on the flanges that surround the top opening of the container since such flanges are then still covered by non splitted parts of the sealing sheet.

Patent CA-2556099-A1 (CA)
Title: Audio coding
Inventor: GAYER MARC
IPC: G10L19/032
Filed: 2005-02-10
Abstract: The aim of the invention is to dispense with the previous procedure, i.e.  interpolation at the filter coefficients and the amplification value in order to obtain interpolated values for the intermediate audio values starting from the support points. Coding containing fewer audible artifacts can be obtained by using the performance limit derived from the masking threshold, preferably from the area below the square sum of the masking threshold, for each support point, i.e. for each parameterization that is to be transmitted, instead of interpolating the amplification value, and then performing interpolation between said performance limits of adjacent support points, e.g. linear interpolation. An amplification value can then be calculated from the determined intermediate performance threshold value at the coder end and the decoder end in such a way that the quantizing noise which is caused by quantizing and whose frequency is constant before post-filtering is done at the decoder end, lies below the performance limit or corresponds thereto following post-filtering.
