Patent CA-2208850-A1 (CA)
Title: Digitally compensated direct conversion receiver
Inventor: SALLENHAG MARTIN
IPC: H04B1/10
Filed: 1995-12-19
Abstract: A digitally compensated direct-conversion receiver includes devices for generating digital samples of a base-band in-phase signal and a base-band quadrature signal and for detecting the presence of a second-order product signal produced by an amplitude-modulated interfering signal. Also, the apparatus comprises a device for digitally compensating the digital samples by removing the second-order product signal, thereby producing compensated digital samples. In one method of digitally compensating samples of an information signal quadrature-modulating a carrier signal, estimated samples of a second-order product from a switched carrier signal are formed by averaging the digital samples during two time periods and by determining a time of ramps in the in-phase and quadrature signals that occur between the time periods due to the interfering signal. The digital samples may be differentiated and the results smoothed in determining the time of the ramps.  In another apparatus, the estimated samples of the second-order product signal are produced by a device for averaging a square of a difference between respective digital samples of the in-phase signal and the quadrature signal, thereby determining an amplitude of the amplitude-modulated carrier signal, and a device for combining the amplitude and the digital samples, thereby generating the estimated samples.

Patent CA-2210899-A1 (CA)
Title: Processing speech coding parameters in a telecommunication system
Inventor: VAINIO JANNE
IPC: G10L19/005
Filed: 1996-02-28
Abstract: The present invention relates to processing speech coding parameters in a telecommunication system. The speech coding parameters of a speech frame, produced by a speech encoder, are divided into groups, i.e. so-called virtual channels, in which speech parameter error correction, channel coding and processing of error-free or erroneous speech parameters are performed independently. At the receiving end, the processing (505) of erroneous and error-free speech parameters can thus be controlled independently on each virtual transmission channel (502) according to the quality of each virtual transmission channel. The speech parameters of the high-quality virtual channels of a speech frame can thus be processed as error-free, replacing the speech coding parameters of the low-quality virtual channels only. The independently processed (505) speech parameters of the virtual channels are thus reassembled (507) into a speech frame, which is applied to decoding. Since part of the information of also erroneous speech frames is utilized, the use of speech information received from a transmission channel can be increased in speech decoding, which reduces for instance interruptions occurring in speech as compared with a situation where all speech frames erroneous even to a slight degree were discarded. The increased and more focused error indication also reduces the number of undetected errors and thus reduces significantly the worst audible disturbances.

Patent CA-2227832-A1 (CA)
Inventor: LUCKOW HANS-JUERGEN
IPC: B65D85/00
Filed: 1998-01-22
Abstract: The cassette is used for the storage of compact disks and it includes a lower shell and an upper shell, which is pivotably connected to the lower shell. At least one release button, in a starting position, holds the upper shell in a fixed location relative to the lower shell. In a release position, the release button allows the pivoting of the upper shell relative to the lower shell. After pivoting the upper shell upwardly relative to the lower shell, the compact disk is released without any significant clamping force being applied. When the upper shell is pivoted upwardly relative to the lower shell, the compact disk is released essentially without the application of a clamping force. When the upper shell is pivoted upwardly relative to the lower shell the compact disk is essentially free of overlap in a central opening with respect to the lower shell. It is likewise possible, without carrying out a release function, to merely provide for assistance in the handling ability by providing a retaining element, which is free of overlap relative to a by-pack element.

Title: Deaeration vessel
Inventor: LUQMANI HAMID
IPC: B01D19/00
Filed: 1996-10-21
Abstract: The present invention relates to a deaeration vessel used in the paper and pulp industry. Especially it relates to an improved double-acting deaeration vessel. As implied by their name, these vessels are purposed for removing gas from a fiber suspension (a first medium). Deaeration vessels are large vessels, into which a fiber suspension to be fed into a paper machine is led as a dilute mixture. It is previously known that the final consistency of the stock to be fed from the headbox to the wire section is preferably fine-adjusted just before the headbox or in connection therewith. This fine adjustment requires deaerated fresh water or equivalent (a second medium). It is characteristic of the deaeration vessel in accordance with the invention that the same gas space (17) where the first medium is treated in the vessel (2), is provided with a second partition wall (13) forming a second weir K2 and that the vessel jacket is provided with an inlet/inlets (11) for a second medium to be introduced into the vessel and with an outlet (14) for a substantially gas-free second medium, and that the common gas space (17) is provided with an outlet (7) known per se, which outlet is intended for the gas separated from both the first and the second medium, and with an outlet (8, 15) for the surface flow/fraction (19) of the second medium separated by weir K2.
