LoopHIL: Looping Hardware into LLM-assisted Agents for Wireless Embedded Systems
Dhairya Shah, Spanddhana Sara, Savitha Viswanadh Kandala +1
LLM agents are widely used for software development and debugging, but their adoption in embedded systems, especially for wireless tasks, remains limited. This is because embedded…
HILO: Enabling Low-power, Dual-Band Communication using Tunnel Diode Oscillators
Dhairya Shah, Rajashekar Reddy Chinthalapani, Pramuka Sooriya Patabandige +1
Wireless communication remains the most power-consuming operation in embedded systems. Low-power transmitters such as backscatter achieve microwatt-scale operation but produce weak…
TinyLLM: A Framework for Training and Deploying Language Models at the Edge Computers
Savitha Viswanadh Kandala, Pramuka Medaranga, Ambuj Varshney
Language models have gained significant interest due to their general-purpose capabilities, which appear to emerge as models are scaled to increasingly larger parameter sizes. Howe…
TunnelSense: Low-power, Non-Contact Sensing using Tunnel Diodes
Lim Chang Quan Thaddeus, C. Rajashekar Reddy, Yuvraj Singh Bhadauria +3
Sensing the motion of physical objects in an environment enables numerous applications, from tracking occupancy in buildings and monitoring vital signs to diagnosing faults in mach…
PixelGen: Rethinking Embedded Camera Systems
Kunjun Li, Manoj Gulati, Steven Waskito +3
Embedded camera systems are ubiquitous, representing the most widely deployed example of a wireless embedded system. They capture a representation of the world - the surroundings i…
VoCopilot: Voice-Activated Tracking of Everyday Interactions
Sheen An Goh, Manoj Gulati, Ambuj Varshney
Voice plays an important role in our lives by facilitating communication, conveying emotions, and indicating health. Therefore, tracking vocal interactions can provide valuable ins…
TunnelScatter: Low Power Communication for Sensor Tags using Tunnel Diodes
Ambuj Varshney, Andreas Soleiman, Thiemo Voigt
Due to extremely low power consumption, backscatter has become the transmission mechanism of choice for battery-free devices that operate on harvested energy. However, a limitation…
Visible Light Communication for Wearable Computing
Ambuj Varshney, Luca Mottola, Thiemo Voigt
Visible Light Communication (VLC) is emerging as a means to network computing devices that ameliorates many hurdles of radio-frequency (RF) communications, for example, the limited…
LoRea: A Backscatter Architecture that Achieves a Long Communication Range
Ambuj Varshney, Oliver Harms, Carlos Perez Penichet +3
There is the long-standing assumption that radio communication in the range of hundreds of meters needs to consume mWs of power at the transmitting device. In this paper, we demons…
dRTI: Directional Radio Tomographic Imaging
Bo Wei, Ambuj Varshney, Wen Hu +3
Radio tomographic imaging (RTI) enables device free localisation of people and objects in many challenging environments and situations. Its basic principle is to detect the changes…
