Title: Two-dimensional web property variation modeling and control
Inventor: CHEN SHIH-CHIN
IPC: G01N33/34
Filed: 1998-04-01
Abstract: A new two-dimensional (2D) variation modeling and control technique for a machine producing a web of material, such as paper, uses functional transformation with basis functions which are wavelets, preferably wavelets derived from and closely resembling the responses generated by actuation of cross direction (CD) actuators of the machine. By using the disclosed functional transformation together with carefully selected basis functions, memory and real-time processing requirements are substantially reduced so that practical controls can be readily implemented. In addition, the functional transformation technique of the present application expands conventional CD  correction to also correct for a portion of the residual variations which, until now, have remained uncorrected. The new 2D profile is treated as the superposition of two main components: a pure machine direction (MD) variation component and a two-dimensional sheet variation component.

Filed: 1997-02-19
Abstract: An improved forming section of the twin wire type for a papermaking machine is described which increases the fibre content of the formed web of paper while reducing the use of energy intensive vacuum dewatering aids relative to prior apparatus. Stock is injected from the headbox of the machine onto a forming wire which is brought into gradual engagement with a second forming wire. The two wires are directed by a forming shoe along a path of increasing curvature, above which water is drained by adjustable auto slices. The two wires with the web therebetween then follow an oscillating S-path between seven S-rolls and are directed upwardly through three individually loaded press rolls with increasing pressure to about four hundred and fifty pounds per linear inch at the last wet press, the press rolls being individually pneumatically pivotable to increase nip pressure and collectively pivotable to open all the nips. Using a high pressure dry nip, the fibre content of the web can be increased to thirty-five percent fibre. Through improved water removal capabilities of the forming and pressing sections the head of the drying section in the papermaking machine, significant cost advantages are realized.
Patent CA-2254375-A1 (CA)
Inventor: HULICK TIMOTHY P
IPC: H04B1/10
Filed: 1998-11-13
Abstract: Out-of-channel intermodulation distortion in a combined analog and digital television (DTV) signal is corrected using a circuit preferably operating at intermediate frequency (IF). The circuit provides out-of DTV-channel suppression of DTV intermodulation components in a way that better protects an analog (for example, NTSC) signal in an immediately-adjacent channel at radio frequency (RF). When adjacent-channel DTV and analog television signals are amplified by a single, high-power amplifier, the intermodulation corrector circuit suppresses the out-of-DTV-channel DTV intermodulation products to below the threshold of visibility (TOV) of the analog channel viewer. In particular, an exemplary circuit has a first mixer receiving the input DTV signal at both inputs. A  second mixer receives the first mixer's output and the input DTV signal, and provides a broadband intermodulation cancellation signal. Finally, the input DTV signal is delayed in time so that it is aligned with a phase-and amplitude-adjusted cancellation signal, and then is combined with it (such as by summing) so as to provide a corrected DTV signal that provides for substantial elimination of the out-of-band intermodulation distortion at the RF output of the transmitter.

Title: Connection aggregation in switched communications networks
Inventor: BELSER DAVID
IPC: H04L12/46
Filed: 1997-06-02
Abstract: A method and apparatus are provided for connection-oriented switching in a communications network wherein a pre-established path is established between a select pair of an ingress switch and an egress switch. The use of pre-established paths enables a reduction in the total number of connections required inside the switch cloud, reduces the CPU load on trunk switches, and shortens the time for connection setup. In the embodiment described, the DA/SA  fields of a MAC frame data packet are replaced with a "virtual path", which identifies the pre-established path between the ingress and egress switches. A  "virtual circuit" is provided in another field of the modified packet which specifies the out-port and out-header on the egress switch for demultiplexing the modified packet upon receipt at the egress switch. The virtual circuit is exchanged between the ingress and egress switches at connection setup. The virtual path is assumed to already be in place, and known to both switches, prior to connection setup.

Patent CA-2268555-A1 (CA)
Title: Dynamic call vectoring
Inventor: BURRITT DAVID R
IPC: H04M3/00
Filed: 1999-04-12
Abstract: A telecommunications switching system such as a private branch exchange (100) processes calls as follows. When it receives (200) a call associated with an individual vector directory number (VDN), the switching system invokes conventional vectoring (107) and commences processing the call by executing (202) the VDN's call-processing vector. However, when it encounters (206) a "wait" vector command in the executing vector, the switching system sends (208) a notice of the call and the call's identity to an external source of vectors, such as an expert system implemented on an adjunct processor (110).      This notice functions as a request for another call-processing vector for the call. The expert system obtains (252-256) information relevant to processing of the call from the switching system and from external databases (111-112), and based on that information dynamically creates (258) a new call-processing vector for the call, in real time. When the switching system receives (220) this new vector, it replaces (222) the old vector with the new vector and continues processing of the call by restarting (224) vector processing and executing (202) the new vector.     The switching system may obtain yet additional vectors for processing this call in the same manner as it obtained the second vector. The switching system may also obtain a new vector from the external source for each newly-received call.
