Abstract: Example implementations involve a location system, which can involve associating each location of one or more unidentified targets detected from sensor data of the one or more sensors with identifiers corresponding to the transmitter of each of the one or more pairs of electronic devices, by calculating first distance relationships indicative of relationships of distances between the each location of the one or more unidentified targets detected from the sensor data of the one or more sensors and a reference point; calculating second distance relationships indicative of relationships of distances between the transmitter and the receiver of each of the one or more pairs of electronic devices; and associating the identifiers corresponding to the transmitter of the each of the one or more pairs of electronic devices with the each location of the one or more unidentified targets based on the first distance relationships and the second distance relationships.

Abstract: Systems and methods described herein are directed to minimizing the resource requirements for edge and network while keeping the accuracy of machine learning classifier by utilizing simulated test data. Once sufficient measured test data is collected by the server, the server instructs the edge computer to reduce the transmission of data received from the corresponding sensors.

Abstract: A gyroscope includes connecting portions which are provided between a mass body and a mass body and connects the mass body with the mass body. Here, the connecting portions includes a fixing portion fixed to a substrate, a shuttle provided between the fixing portion and the mass body, a shuttle provided between the fixing portion and the mass body, a beam connecting the fixing portion with the shuttle, a beam connecting the fixing portion with the shuttle, a beam connecting the mass body with the shuttle, a beam connecting the mass body with the shuttle, and a beam connecting the shuttle with the shuttle. The fixing portion is provided between the shuttle and the shuttle.

Abstract: Example implementations described herein are directed to systems and methods for extracting signal in presence of strong noise for industrial Internet of Things (IoT) system especially for monitoring systems of consumable items such as lathe machines, coolers and so on. Example implementations can utilize a sawtooth mother Wavelet instead of usual wavelet analysis to cleanse the incoming sensor data, thereby allowing for the converting sensor data to feature values despite having heavy noise interference.
