Distributed sensor network for sensing educational interaction in early childhood classrooms
… context through motion and ambient sound data. In this system, I designed a distributed sensor network protocol to collect sensory data, a synchronized network event scheduling scheme to establish a shared time basis, and a wireless data transfer protocol to facilitate data collection from …

Data Rate Enhancement in Ultrasonic Data Telemetry Links
… a novel technique for the enhancement of data rate in wireless data transfer through ultrasonic telemetry links. Referred to as INtervened-Timing, Enhanced-Rate Interval Modulation (INTERIM), the proposed technique is an isochronous pulse-based modulation technique, which embeds the …

A wireless, low power, asynchronous, multi-sensor, temperature network
Wireless communication is not new. Radio and television broadcasting, as well as air traffic control have used wireless signals in their products for decades. The transmitters for these applications require large antennas and a lot of power to drive the signal to many receivers, certainly too much …
