Brain-Computer Interfacing

Brain-computer interfaces (BCIs) are devices that process a user’s brain signals to allow direct communication and interaction with the environment. BCIs bypass the normal neuromuscular output pathways and rely on digital signal processing and machine learning to translate brain signals to action. Brain signals are recorded either noninvasively from electrodes placed on the scalp [electroencephalogram (EEG)] or invasively from electrodes placed on the surface of or inside the brain.

Next Generation 3D Television Demo, sponsored by Santa Clara Valley Chapter and HDI US, Inc.

We are in the early days of 3D television and 3D movie proliferation. In the June meeting of the IEEE Signal Processing Santa Clara Valley Chapter, the participants exploited the next generation 3D television demo, with Ingemar Jansson (the founder of HDI US, Inc.) and Edmund Sandburg (the inventor of the HDI Laser 3D HDTV projection system). The event was on June 14 at HDI US, Inc., a research and design firm that has perfected laser-driven 3D projection display technology after more than three years of intensive R&D.

Compression of Medical Sensor Data

Given the prevalence and success of speech, audio, image, and video compression algorithms in consumer electronics, it is surprising that many high-speed digital signal processing (DSP) systems such as wireless infrastructure, radar processing, and medical imaging sensor subsystems have until recently not considered compression as an alternative for reducing data acquisition bandwidth and storage bottlenecks.
