An ultrasound receiver channel for vagus nerve imaging

The neuromodulation modality based on the focused ultrasonic stimulation (FUS) has gained its interests for being non-invasive while having unprecedented high spatial resolution and deep penetration. The commercially available image-guided FUS device for neuromodulation setups are normally bulky, by employing an 1-D array transducer element to...

In Light and In Darkness, In Motion and In Stillness: A Reliable and Adaptive Receiver for the Internet of Lights

LEDs in our buildings, vehicles, and consumer products are rapidly gaining visible light communication capabilities. LED links however are notorious for being unreliable: shadowing, blockage, mobility, external light, all of these issues can disrupt the connectivity easily. Therefore, unless a reliable and cost-efficient data link layer is...

Leveraging smart lights for passive localization

Localization based on visible light is gaining significant attention. But most existing studies rely on a key requirement: the object of interest needs to carry an optical receiver (camera or photodiode). We remove this requirement and investigate the possibility of achieving accurate localization in a passive manner, that is, without...
