This sComm UbiDuo is a system designed to enable the deaf to communicate freely in person, without an interpreter. The system is composed of two units, each of which has a full keyboard and LCD display. The two units communicate wirelessly using a proprietary chat protocol and user interface. The wireless network allows multiple users to chat simultaneously.

Pivot International designed and manufactures the product, which has an overall product envelope of 2" x 11" x 7.25". The system is built to MIL-PRF-28800F class 3 standards.

The sComm 200A features several battery life advantages, with the ability to operate for up to 8 hours in chat sessions and endure a minimum of 100 charge and discharge cycles. Using proprietary software, we equipped the device with an embedded system without depending on an off-the-shelf operating system. Because the software is proprietary, the software and firmware are nearly impossible to copy or hack.

To further enhance the product, Pivot included a range of unique features, including data storage for chat session log files, a standard QWERTY keyboard, and a backlit LCD display. At the heart of the system, we utilized an ARM920 T microprocessor core, which helps to enhance the multimedia experience.

As part of design verification, we conducted vibration testing in accordance with IEC 68-2-6 and shock testing per IEC-60068-2-27 standards. Reliability tests were carried out to guarantee the operating life was no less than 2 years under normal conditions, which included ensuring the device could be powered on for 4 hours per day, 5 days per week, and 50 weeks per year. After all of this and a wide range of other industrial standards were checked and met, we delivered the first of many orders of sComm 200A systems to the client.
