Patent CA-2156655-A1 (CA)
Inventor: HEUTMAKER MICHAEL S
IPC: H04B17/40
Filed: 1995-08-22
Abstract: A method is provided for accomplishing unified testing of a digital/RF system (10'), comprised of a digital controller (14), a base band processor (20), an RF transmitter (24) and an RF receiver (34). The digital portion of the digital/RF system (10'), including the digital controller (14) and the base-band processor (20), is tested by a digital test technique such as Boundary-Scan testing. Test patterns for the RF elements are down-loaded from the digital controller (14) to the base-band processor via a Boundary-Scan Test Access Port (TAP). Thereafter, the RF transmitter (24) and the RF receiver (34) are tested by applying the test patterns from the base-band processor to the RF transmitter for transmission thereby. The signal produced by the RF transmitter (24) in response to the applied test pattern is converted to a first digital signal stream for processing by the base-band processor (20) to determine the operability of the transmitter. The signal produced by the RF transmitter (24) is also received by the RF receiver (34) for demodulation thereby. The demodulated signal is then converted to a second signal stream for input to the base-band processor to determine the operability of the receiver.

Title: Zero-Sequence Current Suppressor
Inventor: YU LUKE Y
IPC: H02H3/16
Filed: 1995-08-31
Abstract: Harmonics due to single-phase non-linear loads, together with normal load unbalances, can produce overloads and burnouts of grounded-neutral source transformers and their neutral connec-tions.  A system is disclosed which will avoid or greatly amel-iorate such problems through the application of a zig-zag trans-former 5 together with unique system re-connections N, 2d, 2e, 5e.          Said system is comprised of a zig-zag transformer 5 having phase windings 5a, 5b, 5c connected in shunt across the electrical load devices 3a, 3b, 3c, and with neutral terminal connected to ground and to the neutral terminal 3d of said electrical load devices. The system ground is moved from the neutral terminal 2c of said source transformer to the neutral terminal 5d of said zig-zag transformer.  The original ground point may be retained by dis-connecting the ground connection 2d and the neutral conductor N from said source transformer neutral terminal 2c and connecting them together at a junction point 2e.

Title: Process for isolating and purifying nucleotide-activated sugars from biological sources
Inventor: SEIFFERT-STOERIKO ANDREAS
IPC: C12P19/30
Filed: 1995-09-01
Abstract: The present invention relates to an improved process for isolating and purifying sugar nucleotides, in particular cytidine monophosphate-activated N-acetylneuraminic acid (CMP-Nana),  from biological sources. The sugar nucleo-tides can be obtained from a sugar nucleotide-containing solution, which has been freed of proteins by alcoholic precipitation, by means of an improved column-chromato-graphic method which uses silica gel as the stationary phase, at a purity which is so great that a subsequent desalting step is all that is required to isolate them.

Title: Method for traffic routing in a communications network
Inventor: FESTL ROBERT
IPC: H04Q3/66
Filed: 1995-09-11
Abstract: In order to determine the second path in the case of nonavailability of a direct path between neighbouring switching nodes (R, A, PA, M, WM, RO), there are held in the individual switching nodes priority lists (OSW, PSW) in which, ordered in terms of the degree of loading, the direct paths to the neighbouring nodes and the direct paths from these neighbouring nodes to the neighbouring nodes thereof are identified. By comparing the priority list of the originating node with that of the neighbour-ing destination node, that neighbouring node whose direct paths to the originating and destination nodes promise the highest switching probability is selected as inter-mediate switching node of a second path.

Title: Method and apparatus for determining the sensitivity of inputs to a neural network on output parameters
Inventor: KEELER JAMES DAVID
IPC: G05B13/02
Filed: 1994-04-28
Abstract: A distributed control system (14) receives on the input thereof the control inputs and then outputs control signals to a plant (10) for the operation thereof. The measured variables of the plant and the contol inputs are input to a predictive model (34) that operates in conjunction with an inverse model (36) to generate predicted control inputs. The predicted control inputs are processed through a filter (46) to apply hard constrains and sensitivity modifiers, the values of which are received from a control parameter block (22). During operation, the sensitivity of output variables on various input variables is determined. This information can be displayed and then the user allowed to select which of the input variables constitute the most sensitive input variables. These can then be utilized with a control network (470) to modify the predicted values of the input variables. Additionally, a neural network (406) can be trained on only the selected input variables that are determined to be the most sensitive. In this operation, the network is first configured and trained with all input nodes and with all training data. This provides a learned representation of the output wherein the combined effects of all other input variables are taken into account in the determination of the effect of each of the input variables thereon. The network (406) is then reconfigured with only the selected inputs and then the network (406) again trained on only the input/output pairs associated with the select input variables.

Title: Method and device for encoding image signal and image signal decoding device
Inventor: EBRAHIMI TOURADJ
IPC: H04N7/26
Filed: 1995-04-20
Abstract: A video signal coding method and apparatus thereof and a video signal decoding apparatus of the present invention improves visual picture quality of a decoded image with higher compression rate than ever. A video signal (S1) is resolved into local luminance information composed of the smooth component, edge information composed of contour component, and texture information composed of component other than the smooth component and the contour component corresponding to each different visual importance. Then, the local luminance information is coded (S2) by a coding method which restores all of the local luminance information, the edge information is coded (S4) by a coding method by chain information and amplitude information, and the texture information is coded by a coding method having higher compression rate compared with the local luminance information (S2) and the edge information (S4). The coding can therefore be performed with higher compression rate than ever and in consideration of the visual picture quality of the restored image.

Title: Attachment for a shower curtain assembly
Inventor: LAURIE EFFIE P
IPC: A47K3/38
Filed: 1996-09-23
Abstract: A shower curtain control comprised of two niche-controls mounted on the shower curtain rod, when pulled closed will effectively fit the contours of the shower enclosure walls, forming (see fig. I) squared corners. The curtain would be closed with one motion as familiarly used, no additional effort being required. With the shower curtain forming squared corners, this will eliminate the gap between the end of the curtain and the wall, the water is contained in the shower enclosure, making the floor surface outside the shower enclosure safer to step out on. The water damage to walls and floors would be eliminated, however, the ease of showering and cleaning the shower enclosure would remain the same. This design allows two shower niche-controls to form a (see fig. II)-shape for the shower curtain to be attached to, allowing ease of installation, maintenance and use as well as offering a safer system for users than currently existing systems.
