Patent CA-2267004-A1 (CA)
Inventor: FISHER BART LEE
IPC: G06F21/62
Filed: 1999-03-24
Abstract: An access control database has access control objects that collectively store information that specifies access rights by users to specified sets of the managed objects. The specified access rights include access rights to obtain management information from the network. An access control server provides users access to the managed objects in accordance with the access rights specified by the access control database. An information transfer mechanism sends management information from the network to a database management system (DBMS) for storage in a set of database tables. Each database table stores management information for a corresponding class of managed objects.      An access control procedure limits access to the management information stored in the database tables using at least one permissions table. A permissions table defines a subset of rows in the database tables that are accessible to at least one of the users. The set of database table rows that are accessible corresponds to the managed object access rights specified by the access control database. A user access request to access management information in the database is intercepted, and the access control procedure is invoked when the user access request is a select statement. The database access engine accesses information in the set of database tables using the permissions tables such that each user is allowed access only to management information in the set of database tables that the user would be allowed by the access control database to access.

Title: Optical random-number generator based on single-photon statistics at the optical beam splitter
Inventor: DULTZ WOLFGANG
IPC: H03K3/84
Filed: 1997-09-17
Abstract: The invention concerns a random-check venerator for generating a random number which is preferably represented in binary form, with a particle source, a random-check generating element which acts on particles emitted by the particle source and a detection system which allocates a numerical value, preferably in binary form, to the detection of a panicle emerging from the random-check generating element.      The object of the invention is to ensure that the random-check generator is not susceptible to external interference and delivers high-quality random numbers.      To that end, the particle source can emit at least two particles substantially simultaneously, and one particle can ac~te the detection system in order to ~ect a further particle influenced by the random-check generating element and allocate a numerical value thereto.
Patent CA-2268726-A1 (CA)
Title: Piston and drive assembly for use in a pump
Inventor: GRUETT DONALD G
IPC: F04B49/12
Filed: 1999-04-14
Abstract: A single-piece piston and drive assembly for use in a motor-actuated pump to meter a predetermined amount of lubricant or other liquid. The drive assembly includes a rotatable drive shaft, an eccentric cam insert, a cam rod, and a walking beam. The walking beam is coupled to the piston, the cam rod shaft, and a biasing mechanism. When the drive shaft is rotated, movement of the cam rod shaft causes the walking beam to pivot and move the piston along a stroke to dispense the liquid. The piston operates in association with a flow adjustment stem that regulates the amount of liquid metered by the pump, and a valve assembly for evacuating the liquid from the pump chamber into and through an outlet fitting.

Title: Gels, methods and apparatus for identification and characterization of biomolecules
Inventor: PAREKH RAJESH BHIKHU
IPC: G01N27/62
Filed: 1997-12-01
Abstract: The present invention provides computer-assisted methods and apparatus for identifying, selecting and characterizing molecules in a biological sample. A two-dimensional array is generated by separating biomolecules present in a complex mixture. A computer-readable profile is constructed representing the identity and relative abundance of a plurality of biomolecules detected by imaging the two-dimensional array. Computer-mediated comparison of profiles from multiple samples permits automated identification of subsets of biomolecules that satisfy pre-ordained criteria. Identified biomolecules can be automatically isolated from the two-dimensional array by a robotic device in accordance with computer-generated instructions. A supported gel suitable for electrophoresis is provided that is bonded to a solid support such that the gel has two-dimensional spatial stability and the solid support is substantially non-interfering with respect to detection of a label, such as a fluorescent label, associated with one or more biomolecules in the gel.

Title: Method for making elastic bumps
Inventor: BODOE JAN PETER
IPC: B29C33/64
Filed: 1997-12-19

Title: Method of exiting collect information phase in intelligent network
Inventor: TUUNANEN HEIKKI
IPC: H04M3/42
Filed: 1998-10-26
Abstract: The invention relates to a method of exiting a collect information phase at an IN service switching point in such a way that call set up control is transferred from the IN service switching point (SSP) to the control point (SCP), even though the maximum of information requested as additional information by the IN service control point has not been received. In the method, a new condition (EE) is determined for the collecting phase (PIC2) and after the condition is fulfilled, the collecting phase is exited in such a way that the service control point (SCP) can make a decision how the call will be continued. The condition (EE) is either the maximum collecting time (collectTimer), which determines for how long the collecting of information is allowed to take at the most, or the minimum number (minNumberOfDigits), which determines how many digits at least have to be collected. The invention further relates to an intelligent network, an IN service control point and an IN service switching point, to which the method can be applied.

Abstract: A method for optimizing the return on a bank's capital comprises the creation of a plurality of arrays, comprising a passiva product array, an activa product array, a distribution array and a result array. Passiva products are categories of funds on deposit at the bank; activa products are categories of loans made by the bank. Banking laws and principles of prudent management limit the percentage of funds from a given passiva product which may be applied to a particular activa product. The invention comprises the steps of setting up the arrays (110), selecting the highest interest activa product (112, 114), selecting as much of each passiva product as possible to be invested in this activa product (116 through 128), and repeating these steps (130, 118) until all funds from passiva products have been allocated to activa products (132).
