Title: Cellulose pulp production using a substantially constant diameter digester
Inventor: STROMBERG C BERTIL
IPC: D21C7/00
Filed: 1998-07-21
Abstract: In a vertical digester for producing chemical pulp, or other vessel for treating a slurry of comminuted fibrous cellulosic material, the cost of manufacturing the shell is significantly reduced by eliminating the external step increases in the digester shell. The digester shell has a substantially constant internal diameter from just below the inlet to just above the outlet, screen assemblies being provided by an internal transition (e.g. conical) having an angle of convergence of less than 40° (e.g. about 10-25°) above each screen assembly so that the slurry flows through the transition without bridging or hang-up, and a step increase, or other increase, in diameter back to the first diameter after the screen assembly.

Title: High current ground fault circuit interrupter
Inventor: CHAN DAVID Y
IPC: H01H83/02
Filed: 1998-08-24
Abstract: A high current ground fault circuit interrupter has an induction sensor mounted on the device remote from the ground fault circuit interrupter circuitry in such a manner as to allow cables capable of carrying larger currents than the current carrying capability of the contacts in the interrupter circuitry to be passed therethrough. The induction sensor carries a differential transformer for sensing line to ground faults and a neutral transformer for sensing neutral to ground faults. It makes use of an external contactor whose coil is engaged by contacts of the ground fault circuit interrupter to interrupt the cables carrying the high currents, even at a distance somewhat remote from the ground fault circuit interrupter. The induction sensor has the capability of carrying therethrough cables of 240 volts AC line to ground or line to line.
Patent CA-2248017-A1 (CA)
Inventor: BORER TIMOTHY JOHN
IPC: G06T7/20
Filed: 1997-03-03
Abstract: A technique is disclosed for estimating the measurement error in motion vectors used for example in a motion compensated video signal process. For each motion vector corresponding to a region of an image a plurality of temporal and spatial image gradients are calculated corresponding to that region. From the constraint equations of the image gradients a plurality of error values can be calculated for each motion vector and a parameter generated describing the size of the distribution of motion vector measurement errors. Subsequent processing of the video signals using the motion vectors can then be adapted, for example by graceful fallback in motion compensated interpolation, depending on the accuracy of each motion vector. The 'confidence' in the accuracy of each motion vector can be described by a parameter calculated in relation to the size of the error distribution and the motion vector speed.

Title: Automatic coupling of audio signals from an analog network to a digital network
Inventor: TOWLE THOMAS TRAYER
IPC: H04B7/26
Filed: 1998-10-06
Abstract: In a digital cellular communications network, calls to and from a fax machine or other data equipment coupled to a digital phone require special encoding circuitry. Calls to and from a fax machine or other data device using amplitude and/or phase modulated tones can be handled more efficiently by monitoring such incoming calls for the presence of audio control tones. Upon the detection of such tones, appropriate encoding circuitry is automatically switched in to properly encode/decode data tones so as to permit the automatic transmission of data over a wireless cellular network using CDMA, TDMA or other digital protocols.

Title: Shared memory control using multiple linked lists with pointers, status flags, memory block counters and parity
Inventor: LAU JOSEPH C
IPC: G06F12/02
Filed: 1998-02-05
Abstract: Apparatus and methods for allocating shared memory utilizing linked lists (LLs) use a management RAM which controls the flow of data to/from a shared memory (RAM), and stores information regarding a number of LLs and a free link list (FLL) in the RAM, and a block pointer to unused RAM locations. A head pointer (HP), tail pointer (TP), block counter and empty flag (EF) are stored for each data link list. The HP and TP each include a block pointer and a position counter. The block counter contains the number of blocks used in the particular queue. An EF indicates an empty queue. The FLL includes a HP, a block counter, and an EF. Each page of RAM receiving the incoming data includes locations for storing data. The last location of the last page in a block stores a next-block pointer plus parity information, and in the last block of a queue, is set to all ones. An independent agent used in the background monitors the integrity of the LL structure.

Patent CA-2282015-A1 (CA)
Title: Light-scanning device
Inventor: WULF JUERGEN
IPC: G01N21/88
Filed: 1997-12-04
Abstract: The present invention relates to a light scanning device for exciting and detecting secondary light, especially fluorescent light, on a sample, comprising a light-emitting device for emitting excitation light having a wavelength which is suitable for exciting secondary light on or in the sample, a scanning unit for scanning at least one subarea of the sample with the excitation light, and a detection unit for the secondary light emitted in response to excitation of the sample, the detection unit comprising a detection optics and a detector device. In the case of conventional scanning devices, the spatial resolution on the sample is determined by the scanning element alone. If spot detectors without spatial resolution are used, the detector must be read out and re-initialized after the illumination of each scanning spot on the sample; this results in a waiting time before the scanning beam can be moved to the next scanning spot and, consequently, in a reduction of the read-out velocity.  For avoiding this drawback and for increasing the read-out velocity as well as for improving the spatial resolution on the sample, the device according to the present invention makes use of a detector device comprising a large number of detection elements arranged in an array with predetermined position coordinates, the detection elements being arranged in an imaging plane of the detection optics and converting light detected in spatially resolved manner into electric signals.

Title: User interface for television schedule system
Inventor: ROOP JOHN H
IPC: G06F3/023
Filed: 1991-09-10
Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of the cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells, abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.
