Abstract:

A Decision Support System (DSS) coalescer offloads and transforms data from an online statistical gathering database to a report query database adapted for report generation. The coalescer generates and populates a query database structured for query data retrieval, in contrast to realtime access transaction storage as in the online database. Configurations transform the online database into a star join schema (table structure) that centralizes database “facts” in a central table and forms associations to database “dimensions” upon which a query is likely to be based. The facts refer to items which tend to change regularly over time, such as sales volumes and unit shipped. Conversely, the dimensions include more static values such as time (e. g. days, weeks, and quarters) and geographic regions, such as states and countries. The resulting query model (schema) includes relatively small dimensions tables associated with (i. e.

International Classification:

H03F003/04

US Classification:

330/288000, 330/289000

Abstract:

A temperature compensating circuit for use with a current mirror circuit for maintaining a reference current value during temperature variations includes a compensating transistor connected in parallel with a reference current transistor and bias circuitry for biasing the compensating transistor whereby current flows from the reference node to ground through the compensating transistor to remove excess current from the reference transistor when temperature increases. A diode can be included in the bias circuitry for limiting bias current flow when the reference voltage drops below the voltage drop of the diode. An on/off switch circuit can be provided in parallel with the reference current transistor to further reduce reference current in specific applications.

G06F 21/53

Abstract:

A computerized-method for initiating a sandbox-testing-process-flow associated with a client-entity, within a server runtime environment and configuring said sandbox testing process flow with money laundering-detection-rules is provided herein. The computerized-method includes receiving: an instruction for initiating a sandbox-testing-process-flow associated with a client-entity; one or more money-laundering-detection-rules for implementation within the sandbox-testing-process-flow; parameters defining historical-transaction-data to be retrieved by the sandbox-testing-process-flow; monitoring the one or more money-laundering-detection-rules by implementing through the sandbox-testing-process-flow, money-laundering event analysis based on an application of the one or more rules on retrieved historical-transaction-data by the received parameters thereof for generating a money-laundering event determination decision indicative of whether the retrieved historical-transaction-data is an outcome of money-laundering related activity; and transmitting results of the money-laundering event analysis implemented through the sandbox-testing-process-flow to the client-entity to check that the one or more money-laundering-detection rules are error free and do not result in any unintended outcomes or errors.

G06F 11/36

Abstract:

The invention provides methods, systems and computer program products for sandbox enabled testing of money laundering detection rules or rulesets. The invention implements at a money laundering detection server, the steps of (i) receiving a request for a modification of a first ruleset for electronic transaction related money laundering event detection, (ii) identifying a client entity associated with the received rule modification request, (iii) initiating a sandbox testing process flow for testing the requested modification of the ruleset, (iv) generating a modified second ruleset for electronic transaction related money laundering event detection, based on modification information received within or along with the received request for modification of the first ruleset, (v) implementing through the sandbox testing process flow, money laundering event analysis based on application of the modified second ruleset to retrieved historical transaction data, and (vi) transmitting results of the money laundering event analysis to the client entity.
