Image Sensor Reconfiguration Framework for Rapid and Seamless Resolution-Based Optimization
Background Mobile vision systems would benefit from the ability to situationally sacrifice image resolution to save system energy when imaging detail is unnecessary. However, upon any resolution reconfiguration request, current system frameworks stop providing image frames to the application until the reconfiguration completes. Frame delivery is bottlenecked...

IoT-Compatible Spatial Audio System for a Moving User
Background Current spatial audio techniques for speaker systems are challenged by high cost, high computational intensity, and user mobility. In particular, crosstalk—when sound from a speaker unintentionally reaches an opposite ear—is a major performance-degrading factor. Some spatial audio speaker systems utilize beam-forming techniques...
