Publication number: 20050065771Abstract: A method for translating the string literals in a database script from a source language (i.e. English) into a target language (i.e. Chinese). The invention comprises a Conversion Program (CP) and a Field Expansion Program (FEP). The CP copies a database script in a source language and runs the FEP, which analyzes the database script and determines the maximum width of the fields. The user may then adjust the field length as necessary. The CP then substitutes labels for the string literals in the new database script, which creates a message file. The CP uses a pre-existing data file to translate the source language string literals into the target language string literals. The translated message file is called a label file. The CP then uses the label file to substitute the target language string literals for the labels in the database script.Type: ApplicationFiled: September 18, 2003Publication date: March 24, 2005Applicant: International Business Machines CorporationInventors: Yen-Fu Chen, John Handy Bosma, Keith Walker

Publication number: 20050066192Abstract: The invention comprises a Security Program (SP), a Simultaneous Approval Program (SAP), an Access Approval Program (AAP), and a Security Table (ST). A user's ability to access low security and high security applications depends on the user's security clearance, which is recorded in the ST. The SP limits a user's access to the applications. When a plurality of authorized users have logged in, the SP runs the SAP and AAP as required to allow the users to access and modify the high security applications. The SAP allows a user to modify the high security application only when a specified number of users approve the modification. The AAP allows a user to access a high security application only upon another user's approval. The SP terminates the users' access to the high security applications if one of the users logs out.Type: ApplicationFiled: September 18, 2003Publication date: March 24, 2005Applicant: International Business Machines CorporationInventors: John Handy Bosma, Yen-Fu Chen, Keith Walker

Patent number: 6831257Abstract: The present invention is a system that automatically controls the selection, start-up and operation of primary and secondary heating towers chosen from an array of heating towers having varying physical and thermal sizes. The automatic control is implemented via a programmable logic controllers (PLC). The PLC provides independent control for each heating tower irrespective of the tower being a primary or secondary heating source. Should the demand for heated water upon the primary heating tower increase to a rate that the primary tower cannot satisfy, the PLC maintains the operation of the primary tower and at the same time starts the secondary heating tower to meet the increased hot water demand. Once the demand has dropped to rates that the primary heating tower can once again maintain, the secondary tower is disabled.Type: GrantFiled: March 11, 2002Date of Patent: December 14, 2004Assignee: Quikwater, Inc.Inventor: Brian Keith Walker
