Following the SAE's J1587 vehicle communication standard PSA developed additional functionality to display fault code information such as active fault codes and faults history, description of the device, a description of the fault, the device number and the fault number, and the occurrences count for active faults. The diagnostic application tool also provided the capability to clear all historical information. |
| This is a computer telephony IVR (Interactive Voice Response) system which automated notifications to the end customer's clients. Based on an earlier version developed by PSA, this system expanded the previous single line capability to a seven line simultaneous outbound call system. A single line is dedicated for inbound calls to preview and record custom messages. The IVR system has direct dial capabilities, ability to leave messages, share messages for greeting and signoff, and record the status of each call within a Progress database. |
| The project consisted of updating the existing firmware for Serial Server Devices through adding new partial functionality to a Modbus protocol. The project included design and development of a Modbus gateway with a pass-through Ethernet port. The gateway supports the Modbus TCP server and Modbus RTU serial with Modbus slave devices attached to the serial ports. The gateway allows customers to replace the three box solution with a single box solution. Along with new protocol implementation, the internal web server was updated as well as the desktop utility for remote device configuration and firmware update. The created desktop automated testing utility was developed for testing the solution. |
| 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. |
