METHOD AND APPARATUS FOR ACTIVITY DETECTION AND RECOGNITION BASED ON RADAR MEASUREMENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17664017 titled 'METHOD AND APPARATUS FOR ACTIVITY DETECTION AND RECOGNITION BASED ON RADAR MEASUREMENTS
Simplified Explanation
An electronic device with a transceiver and processor is described in this patent application. The processor is connected to the transceiver and is responsible for transmitting radar signals for activity recognition. It also analyzes the reflections of these signals to identify two sets of features. The first set of features determines whether an activity is detected based on the power of the reflections. If an activity is detected, the processor compares the second set of features to specific thresholds to determine if a condition is met. Once the condition is satisfied, the processor performs an action based on a cropped portion of the second set of features.

Original Abstract Submitted
An electronic device includes a transceiver and a processor. The processor is operably connected to the transceiver. The processor is configured to transmit, via the transceiver, radar signals for activity recognition. The processor is also configured to identify a first set of features and a second set of features from received reflections of the radar signals, the first set of features indicating whether an activity is detected based on power of the received reflections. Based on the first set of features indicating that the activity is detected, the processor is configured to compare one or more of the second set of features to respective thresholds to determine whether a condition is satisfied. After a determination that the condition is satisfied, the processor is configured to perform an action based on a cropped portion of the second set of features.
