Abstract: A system and a method for estimating size of a finger of a user. The method comprises acquiring one or more images of a hand of the user and a pre-defined reference object by an image capturing device, and recognizing the pre-defined reference object and the hand of the user, for removal of background of the one or more images.

A second bounding box is assigned to a finger of the hand. A size of the finger of the user is estimated based on dimension of a width of the second bounding box determined from on actual dimensions of the pre-defined reference object.

Abstract: The present invention relates to a method and wearable device for monitoring and analyzing user movements to predict fall risk. The method involves retrieving motion data recorded by an Inertial Measurement Unit (IMU) and a pedometer, followed by processing the data once it exceeds a predefined threshold. A first trained machine learning (ML) model predicts the fall risk based on the processed data. A confidence score is determined from the fall prediction, and a second trained ML model analyzes successive data frames to confirm the fall if the score is above a threshold. If a fall is confirmed, a distress signal is transmitted. The wearable device comprises a processor and memory that stores program instructions to perform the method, including motion data retrieval, processing, fall prediction, confidence scoring, and fall confirmation, along with distress signal transmission. This invention enables timely fall detection and emergency response, improving user safety.

Abstract: Present disclosure discloses a capacitive sensing ring-sizing system. The capacitive sensing ring-sizing system is an advanced device that revolutionizes the ring sizing experience through its integration of sensor technology, wired rings, and a custom-built electronic system. It provides real-time feedback on ring fit, enabling users to find their perfect size with precision and simplicity. According to an embodiment, the capacitive sensing ring-sizing system uses capacitive sensors embedded in the ring to determine how well the ring fits on a finger. Rather than taking physical measurements of the finger size like circumference or diameter, the capacitive sensing ring-sizing system uses changes in capacitance caused by the interaction between the ring, the finger, and the skin's dielectric properties.
