X-NUMBER. Over the weekends and free time, I've been working in a method to improve the data-entry procedures in numerical keyboards (X-Number Method). This was accomplished by the addition of three structured keys and a swap key controlled by a set of special algorithms. In April 22, 1997 I was awarded US patent 5,623,433 for this invention.

On April 14, 2005, with my daughter Maria S. Redin, applied for a related patent for an "Improved Method and Apparatus for Entering Verbal Numerals in Electronic Devices."

Wrote a set of JavaScript and Perl programs to show the operation of the X-Number method, and developed two related Web sites, one devoted to show the capabilities and theory behind the X-Number data-entry procedure, and another oriented to my main hobby and personal interest: calculators.

Currently I'm in the process to write a keyboard for the Google Calculator that will use the X-Number data-entry procedure (in JavaScript), and a Windows calculator (in Visual C++.)

KLIB, a library of Korn Shell functions for Unix scripting.  The library contains about 60 functions that can be used to write menu applications, backup/restore scripts, date manipulation, interactive operations, etc. Used this library to implement the conversion of about 6000 AOS/VS macros to Unix scripts, and develop all the supporting operations of the Keane's Patcom System.
KWEB. An intranet for the LAHD Division of Keane. Among other features, Includes electronic on-line manuals, and automated calendars written in C and Perl, used to track the different shift schedules at Keane's departments.
KLOOK, a C program designed to display and manipulate UNIX files written in different formats. It is widely used at Keane to diagnose and fix file related problems.
KSTS, a search engine used to search for text within an INFOS ISAM database of problem/resolution logs maintained by Keane's support departments.
KCLI, a set of C programs used to convert AOS/VS macros to Korn Shell Unix scripts. These programs were used by Keane to convert 6,000 macros during its conversion project to Unix. Got a Productivity Award for this project.
KAOS, an emulator of the AOS/VS Command Line Interpreter (CLI) written in C designed to run in Unix platforms.
KHELP, an electronic manual generator written in C, with an interactive user interface used to replace bulky reference manuals. It has embedded a search engine.

It also contains a search engine and user interface written in Perl to allow for the posting of the electronic manuals in the Internet.

KMAP, a C program used to gather statistics on disk usage in 150 hospital installations. This work was previously done manually and the time was reduced from about 400 hours to 20 hours/month with increased reliability.
