Scalable Position Tracking System for Tracking Position in Large Spaces
We developed a system that tracks where people are in large spaces, like stores, using cameras and shelf sensors. The cameras figure out where each person is, and the shelves know when something’s been picked up. A central server puts it all together to figure out who took what and when. It’s built to work in big areas and handle lots of people at once.
Adaptive Item Counting Algorithm for Weight Sensor Using Sensitivity Analysis of the Weight Sensor
This system helps figure out how many items were taken off a shelf using a smart weight sensor. If the weight change matches an expected amount (like 2 cans = 2 x 400g), it counts the items directly. If it’s not that simple, it compares the signal to past patterns to make a smarter guess. It’s designed to handle real-world messiness, like weird grabs and wobbly shelves.
Mapping Wireless Weight Sensor Array for Item Detection and Identification
This system tracks which item was placed where using smart weight sensors that each have a unique address. The sensors talk to a central board, which then figures out which item was removed from which spot. It’s like giving each sensor its own name tag in a giant game of Clue.
Systems, Apparatuses, and Methods for Controlling Prosthetic Devices by Gestures and Other Modalities
A low-hassle glove-based system that lets users control prosthetic devices using hand gestures or even sensors on fingernails. It’s Iron Man meets real-life accessibility.
System and Method for Position Tracking Using Edge Computing
This system does all the people-tracking magic right at the camera level using edge computing. Each camera client tracks movements and labels frames with time and location so a server can piece together where everyone is, fast and efficiently.
Tracking Positions Using a Scalable Position Tracking System
A continuation of large-scale tracking. This version adds time windows to group and merge coordinates, helping track where a person is at any given moment in real time.
System and Method for Camera Re-Calibration Based on an Updated Homography
This invention keeps cameras smart by recalibrating them if they move, even slightly. It uses fancy math (homography!) to detect when the view’s off and fixes it, so tracking stays accurate.
System and Method for Detecting a Trigger Event for Identification of an Item
By comparing before and after 3D images of a platform, this system figures out when an item has been placed. If something shows up and stays for a bit, it knows it’s not just passing through, it’s been dropped.
System and Method for Identifying Moved Items on a Platform During Item Identification
When items are added one after another, this system makes sure they’re not confused. It compares cropped images of each placement to match and identify previously seen items, even if they were moved around.
Lighting for an Imaging Device
This smart lighting system fine tunes LED brightness (warm or cool) to keep images consistent. If the color in the camera looks off, it adjusts the lights to match a target look, because image quality matters.
