PSA developers have strong skills in development of solutions based on Unix OS.
UNIX operating systems are widely used in both servers and workstations. The UNIX environment and the client-server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers.
UNIX had a drastically simplified file model compared to many contemporary operating systems, treating all kinds of files as the simple byte arrays.
HP-UX stands for Hewlett-Packard UniX and represents Hewlett-Packard’s proprietary implementation of the UNIX operating system, based on UNIX System V. It provides a dynamic, highly secure and unified environment, built on the always-on resiliency demanded in mission-critical servers.
Sun Solaris (SunOS, Sun) is the Sun company’s UNIX variant operating system. SunOS is a BSD UNIX system representing a full-featured open source operating system designed to scale from home users to enterprises.
FreeBSD is a UNIX-like operating system designed for modern server, desktop, and embedded computer platforms. It provides advance networking, performance, security and compatibility features, making an ideal Internet or Intranet server.

The project objective was to port the ARTM application running on a PC DOS based system under MS Windows 3.1 to a Silicon Graphics Unix Workstation. PSA development team resolved all operating system specifics conflicts using cross platform development tools.
Conversion of an ARTM (Acoustics Requirements Translation Model) and user manual development were successfully completed as well as ARTM upgrade including export of data to plotting program and setting default directories.

This device allows the monitoring of patient's vital signs. PSA's tasks for this project were to develop the screen region management and conduct a port of the ICA client and migrate to UGL 2.0 and Zinc 6.0 to support the region management functionality. PSA also assisted in the development of the next generation patient monitoring device.
The region management consisted of developing the basic input and output screen region management functionality. An 8-bit display was developed for the rendering of graphics. This 8-bit display translated into an available pool of 256 colors. The porting consisted of porting to the new PPC860 architecture, implementing an application layer between the server and the thin client, and developing the graphics component to display graphical elements on the screen for visual representation.

PSA was asked to join a large project which involved telephony based development. This project required from PSA to provide on-site development services for 3 months period at clients' development location. Individual modules were required to be implemented and used in the collaboration of single objects for the final telephony based system.
