Latest Patents

One of Li Zhang's latest patents is titled "Energy-efficient, accelerometer-based hotword detection to launch a voice-control system." This invention relates to a system that utilizes an accelerometer in mobile devices to detect hotwords, which activate a voice interface for recognizing subsequent voice input. The system gathers samples from the accelerometer, calculates features from these samples, and classifies them using a trained classifier. If hotwords are detected, the system launches a voice-control interface to process further audio input.

Another notable patent is the "System for optimizing electricity use from an electric grid and related method." This method focuses on optimizing electricity consumption by formulating a target load using a cost function for the electric grid. It involves broadcasting a cost signal to electric devices, receiving charging profiles, and aggregating demand profiles to determine updated cost signals. This innovation is particularly relevant for chargeable electric devices, such as plug-in electric vehicles (PEVs), ensuring they are charged efficiently.
