Title: Distributed connection control in telecommunication networks
Inventor: DAGBERG OLA LARS JOHN
IPC: H04M3/42
Filed: 1995-05-30
Abstract: The invention relates to a method for handling connection in a telecommunication system comprising digital, computer controlled telephone exchanges and subscribers connected thereto, wherein the connection handling is distributed out in the network.  Physical connections between subscribers are handled under control of abstract connection models, wherein in an object oriented system a number of different, mutually independent use processes are provided in such a manner that one or more of said processes under control of one or more processors control that or those connections which are necessary to achieve e.g. reservation of a connection path, connection set up, through-connection and release of a complete connection, and re-direction of connections.  The invention solves the problem to coordinate a number of processes by means of a set of functional objects which allow each user to control and change a connection in a communication network.  The connection models comprise port objects representing connection end ports and connection objects representing abstract connections between end ports. When objects and models have been linked together in a chain, the connection can be physically set up via a connection set up function.

Title: Clock free two-dimensional barcode and method for printing and reading the same
Inventor: LOPRESTI DANIEL
IPC: G06K7/00
Filed: 1996-12-04
Abstract: Inventive  two-dimensional  barcodes,  each having encoded  digital  information  in  a  bitmap  representing preferably randomized encoded data bits, are printed onto a  printed  medium.   The  bitmap  may  further  include  a plurality  of  block  identifiers,  spaced  a  predetermined number of encoded data bits apart, which are used to make corrections  for  missing  or  added  data  bits  when  the barcode is decoded.   Upon decoding a barcode printed on the printed media, the digital information is scanned and the  number  of  horizontal  and  vertical  edges  in  each respective column and row of the barcode are determined. An edge is determined by selecting a pixel and determining if the two pixels adjacent to the selected pixel are of different  colors.   After all  of the edges are counted, selected  groups  of  columns  and  rows  are  analyzed  to determine  local  minimas   in  the  number  of  counted horizontal and vertical edges in each selected group which provide the column and row center line for each selected group.   Thereafter,  the  binary  data  located  at  the intersection of each column and row center line are read out  to produce  a  signal  representative  of  the  encoded digital information in the printed barcode.

Abstract: A modular rack for packaging and processing a quantity of elongate objects, such as a quantity of syringe barrels, is disclosed. The racks preferably include two or more vertical supports, each of which is attached to a relatively flat base for supporting in the rack on a work surface. A plurality of resilient barrel clips designed to releasably retain individual syringe barrels are secured between the vertical supports. Structure for supporting flanges associated with individual syringe barrels is provided at an upper extremity of the vertical supports. In one configuration, the structure for supporting the flanges includes a pair of plates spaced apart from one another to define a pocket for receiving the syringe flanges. Cut-outs are formed in each of the plates, both to accommodate entry of the syringe barrel adjacent the flange as well as to provide access to the open proximal end of the syringe barrel for processing purposes. Various structures are provided to releasably secure together one or more of the syringe racks so as to form a block configuration of syringe racks for packaging and handling purposes. Alternately, if desired, the individual racks may be releasably detached from the block configuration so as to sequentially handle the individual syringes contained in each rack. The open architecture of the rack permits ready visual inspection of the syringes held by the rack.

Title: Memory manager for mpeg decoder
Inventor: BARNES DAVID ANDREW
IPC: H04N7/50
Filed: 1997-05-12
Abstract: An MPEG decoder operates in 2.5 frame store mode, and has an efficient memory management which allows a B picture to be stored and displayed while simultaneously making use of a portion of the frame store memory. The video frame is treated as a grid, having rows of 8 x 8 pixel blocks. The pixel blocks are manipulated in three FIFOs which are cross-connected in a closed loop. Two processes operateon the memory so arranged: (1) a video reconstruction process which writes data into the memory, and (2) a display process, which accesses the memory and writesthe video frame into another, external memory in a rastered format. One of the three cross-coupled FIFOs is designated for write-back, and the other two for reading 2:1 interlaced raster data. The two FIFOs utilized for the raster operation are allocated to the alternate lines of the picture.

IPC: G11B5/09
Filed: 1996-05-23
Abstract: As depicted in the Figure, a resonant frequency control circuit (18) communicates with a head (14) of a disk drive and a read/write channel (22).  The resonant frequency control circuit (18) is useful in achieving peaking of a readback signal generated by reading data from a magnetic disk (10). The read/write channel (22) includes an equalizer circuit for enhancing equalization of the readback signal. A controller (76) communicates with the read/write channel (22) and the resonant frequency control circuit (18) for, in one embodiment, selectively adding capacitance to that capacitance which is present in the read element (16) of the head (14). By controlling the resonant frequency, this desired signal peaking can be achieved, which is related to the frequencies of the coded data on the disk (10).
Patent CA-2227188-A1 (CA)
Inventor: CAMPBELL SCOTT DOUGLAS
IPC: G16H40/20
Filed: 1998-01-16
Abstract: A software system for managing a health care practice includes interactive software tools for conducting a physical exam, suggesting tentative diagnosis, and managing a treatment protocol. The physical exam software guides the user through a physical exam, prompting the user for input and dynamically generating context sensitive questions based on prior input. The diagnosis software generates a list of possible diagnoses based on the observations recorded from the physical exam. The user can interactively select a diagnosis by selecting a diagnosis from a rule out list and watching the display as the system dynamic updates the status of unresolved symptoms. The user can also select a treatment protocol, which is integrated with future physical exams. The treatment protocol is integrated such that future exam sessions reflect the status of the treatment protocol and remind the user which services need to be performed and when they should be performed.
