Abstract: A system for implementation within a visual sensing pipeline facilitates dynamic voltage scaling for image sensors, enabling image sensors to capture frames at varying fidelities for improved energy efficiency. The system includes hardware and software interfaces to enable dynamic voltage scaling, and are demonstrated with integration into an RPi-based streaming platform. The system is evaluated with representative IoT/AR workloads over various voltage scheduling policies.

Abstract: Described herein are systems, methods, and apparatuses for implementing olfactory delivery in virtualized environments using an olfactory delivery engine. Mimicking physical odor sensations virtually can present users with a real-time odor synthesis that approximates what users would smell in a virtual environment, e.g., as they walk around in virtual reality. A novel Smell Engine is described herein which includes: (i) a Smell Composer framework that allows developers to configure odor sources in virtual space, (ii) a Smell Mixer that dynamically estimates the odor mix that the user would smell, based on diffusion models and relative odor source distances, and (iii) a Smell Controller that coordinates an olfactometer to physically present an approximation of the odor mix to the user's mask from a set of odorants channeled through controllable flow valves.
