Armilla Play Calling

https://armillatech.com/
This is a messaging application targeting the NFL. The coaches each have a tablet that enables them to send radio frequency messages to up to 24 devices in the field. Each player in the field wears a receiving device that receives messages from the coaches and displays up to 200 characters on an e-paper display.

Cleanroom Monitoring System

This IoT-enabled cleanroom monitoring system displays sensor status information received from onboard sensors or the cloud. The system is equipped with an LCD touchscreen and humidity, pressure, and temperature sensors. It also has a high/low power actuator control, speaker, microphone, and proximity sensor. The graphical user interface (GUI) was developed to have multiple widgets and a fully dynamic layout controlled from the cloud.
