Patent CA-2327910-A1 (CA)
Inventor: HARATSCH ERICH FRANZ
IPC: G06F11/10
Filed: 2000-12-08
Abstract: A method and apparatus are disclosed for improving the processing time of reduced complexity sequence estimation techniques, such as reduced state sequence estimation (RSSE). The possible values for the branch metrics in the RSSE are precomputed to permit pipelining and the shortening of the critical path.  Precomputing the branch metrics for all possible symbol combinations in the channel memory makes it possible to remove the branch metrics unit (BMU) and decision-feedback unit (DFU) from the feedback loop, thereby reducing the critical path. A look-ahead branch metrics unit (LABMU) and an intersymbol interference canceller (ISIC) precompute the branch metrics for all possible values for the channel memory. At the beginning of each decoding cycle, a set of multiplexers (MUXs) select the appropriate branch metrics based on the survivor symbols in the corresponding survivor path cells (SPCs), which are then sent to an add-compare-select unit (ACSU). The computational load of the precomputations is reduced for multi-dimensional trellis codes by precomputing each dimension of the multi-dimensional trellis code separately. Prefiltering techniques are used to reduce the computational complexity by shortening the channel memory.  A hybrid survivor memory architecture is also disclosed for a RSSE for a channel having a channel memory of length L, where the survivors corresponding to the L past decoding cycles are stored in a register exchange architecture (REA), and survivors corresponding to later decoding cycles are stored in a trace-back architecture (TBA) or register exchange architecture (REA). Symbols are mapped to information bits to reduce the word size before being moved from the first register exchange architecture (REA) to the trace-back architecture (TBA) or the second register exchange architecture (REA).

Title: Automated tool and method for frequency plan revision within a cellular telephone system
Inventor: GUIMONT VINCENT
IPC: H04W16/18
Filed: 1999-06-22
Abstract: Interference and bit error rate measurements are made on the uplink (106) and downlink (114) to determine communications quality. Mobile station mobile assited hand-off (MAHO) functionality is utilized to make the downlinke measurements. Following filtering, the measurements are evaluated (108) to identify potential candidates for reallocation. In one type of evaluation, when measured downlink bit error rate on a selected frequency is lower than a threshold and is worse than measured uplink bit error rate, then a better quality candidate is chosen to replace the selected frequency. In another type of evaluation, when a best available candidate has better interference than a worst quality one of the selected frequencies, that best candidate is chosen to replace the selected frequency.

Title: Non-molten-mix process for making bar comprising acyl isethionate based solids, soap and optional filler
Inventor: RATTINGER GAIL BETH
IPC: C11D1/04
Filed: 1999-09-14
Abstract: Detergent bar compositions comprising optional fillers with both soap and high levels of acyl isethionate surfactants are prepared.  When high levels of soap and surfactant are normally used in such a process, there is a significant "grittiness" problem. Preprocessing the isethionate containing chip (e.g., "DEFI" chip) has been unexpectedly found to remedy this problem. Preprocessing involves blending of the isethionate with fatty acid soap, optionally surfactant (e.g., betaine) and other minor components using the same process as that used to manufacture final soap (e.g., mixing components at greater than 90 °C for at least 15 minutes, cooling for example on a chill roll, and refining to form chips). The raw material so formed is collected in the form of noodles or chips and then used as the sodium acyl isethionate source in a non-molten process.

Abstract: L'invention porte sur la protéine tensioactive D (SP-D), membre de 43 kDa de la famille des collectines, protéines de collagène contenant le domaine des lectines, exprimée dans les cellules épithéliales des poumons. Le gène SP-D a été ciblé par recombinaison homologue dans des cellules souches d'embryons servant à produire des souris SP-D (-/-).

Title: Real-time method for bit-reversal of large size arrays
Inventor: JIN DONGXING
IPC: G06F7/76
Filed: 2001-07-09
Abstract: A digital signal processor DSP for bit-reversal of a large data array of a size has a direct memory access (DMA) controller for performing in-place bit reversal routines on an external memory during a first stage, and a central processing unit (CPU) for swapping small sub-arrays on internal memory in a second stage. The two stage method according to the invention importantly reduces the real-time implementation for sorting large size data arrays on uni-processor DSP platforms, by extensively using the external memory and avoiding a random access to the internal memory. As well, the invention provides for improved dense integration and reduced costs when used in dense wavelength division multiplexing (DWDM) systems.
Patent CA-2352986-A1 (CA)
Inventor: WOODFIELD RICHARD
IPC: B41J2/45
Filed: 2001-07-12
Abstract: A high density array of light emitting diodes for visual display and imaging purposes. The array is mounted on a thermally and electrically conducting medium such as an aluminum block. The block, in one embodiment, is configured to permit a supplementary cooling liquid to be circulated through it. Typically, such LED arrays are fabricated by forming a plurality of p-type islands in n-type host semiconductor material.  Each p-type island has an individually addressable contact and a common n-type contact is made to the aluminum block by, for example an electrically conductive epoxy. In operation the connection between the carrier and array may be lost due to a temperature differential between the two components. The present invention avoids this problem by providing a separate connection in parallel with or in place of the common n-type contact.

Title: Process for the production of water insoluble needle-shaped precipitated calcium sulphate dihydrate (caso4-2h2o) and its use as a filler in papermaking
Inventor: KERR R BRUCE
IPC: C09C1/02
Filed: 2001-08-13
Abstract: Needle shape calcium sulphate dehydrate (CaSO4.cndot.2H2O) filler particles were prepared by mixing freshly calcined calcium sulphate hemihydrate (CaSO4.cndot.1/2H2O) having an average particle size between 1 and 100 micrometers, and water in a reactor at high sheer with either no additives or together with acids or with calcium-or sulphate- containing additives. The average length and width of the produced filler particles were 5-35 micrometers and 1-5 micrometers respectively. The calcium sulphate dehydrate filler particles were then treated by a calcium chelating agent, perhaps followed by the addition of a weak acid. The mixture was then held at 90°C for 5-60min resulting in relatively water insoluble calcium sulphate dehydrate. The filler suspension can be directly added to the pulp furnish before the paper sheet formation to obtain a high filler retention and improved optical properties with minimal filler losses due to solubility. The resulting filler did not cause any operating difficulties on the paper machine and provided, depending on the filler level, a 2-15% decreased energy consumption in the drying section.
