MALFUNCTION EARLY-WARNING METHOD FOR PRODUCTION LOGISTICS DELIVERY EQUIPMENT

Disclosed is a malfunction early-warning method for production logistics delivery equipment. After a sensor obtains past signal data, performing feature extraction and dimensionality reduction so as to obtain a feature vector; using a growing neural gas (GNG) algorithm to divide normal state data into different operation situations so as to obtain several cluster centers, and calculating the Euclidean distance between the feature vector and the cluster centers obtained from current operation data, so as to obtain a similarity trend; constructing a past memory matrix, using an improved particle swarm algorithm to optimize an LS-SVM regression model parameter, and calculating the residual value of the current state. Finally, combining the residual value and the similarity trend to obtain a risk coefficient, assessing the equipment state, and issuing an early warning for an equipment malfunction.

System and method for autonomous vehicle ride sharing using facial recognition

Methods and systems for identifying autonomous vehicle users are described herein. An autonomous vehicle may receive a request to transport a first user to a first destination location. While travelling along a route to the first destination location, the autonomous vehicle may receive a request to pick up a second user at a second starting location and transport the second user to a second destination location. The autonomous vehicle may travel to the second starting location when the second user is within the threshold distance of the autonomous vehicle. Upon arriving at the second starting location, the autonomous vehicle may detect whether a person approaching the vehicle is the second user by detecting a biometric identifier for the person. As a result, the second user may be allowed to enter the autonomous vehicle and/or the autonomous vehicle may begin travelling to the second destination location.

DETECTING DIAGNOSTIC EVENTS IN A THERMAL SYSTEM

Embodiments of the disclosure provide a thermal model based on an adaptive filter bank for characterizing heat transfer of a volume of a thermal system. In one embodiment, the adaptive filter bank is used for diagnostics that provides information related to the condition of a thermal system. The diagnostics are based on an analysis of heat transfer characteristics of a dynamic representation of the thermal system. In accordance with the embodiments, thermal coefficients are generated based on an adaptive filter bank. One or more filters are applied to the thermal coefficients based on a sampling rate and one or more estimate thermal coefficient thresholds are generated based on the sampling rate. It is determined whether at least one of the thermal coefficients that is filtered satisfies at least one of the estimated thermal coefficient thresholds. Thereupon, alert information indicative of a diagnostic event is provided based on the determination.

Novelty detection of IoT temperature and humidity sensors using Markov chains

Monitoring indoor environmental conditions is provided. Sensor data and its corresponding time stamps from is collect from a number of environmental sensors within an enclosed environment. A set of all possible states is defined for a specified time period, each state representing a range of sensor data values. A probability of the system changing from any one state to another is modeled according to a Markov chain. When a new sensor data value is received from a sensor it is compared to a last sensor data value of a previous state, and a probability of transition from the previous state to the current state is determined. If the probability of transition from the previous state to the current state is less than a predetermined threshold, an anomaly is detected, and a service request is generated.
