Abstract: A method for locating an asset in an environment, the method comprising. The method comprises capturing, with a camera, a first image of the asset, wherein in the first image, a light source positioned on or adjacent to the asset is in a first state; capturing, with the camera, a second image of the asset, wherein in the second image, the light source is in a second state; and determining the location of the asset in the environment based on the first image, second image and camera-specific information.

Abstract: A method for training a machine learning model for locating an asset in an environment when the machine learning model is executed on a computer system, wherein the environment includes a plurality of zones. The method includes receiving data corresponding to first and second sets of training signals, wherein the first and second sets of training signals are received at a plurality of receivers, within first and second data collection periods, respectively, from a plurality of training tags located in first and second zones, respectively, of the plurality of zones. The plurality of training tags are moved from a first position in the first zone to a second position in the first zone within the first data collection period. The plurality of training tags are moved from a first position in the second zone to a second position in the second zone within the second data collection period.

Abstract: A method for training a machine learning model for locating an asset in an environment when the machine learning model is executed on a computer system. The method includes receiving data corresponding to a plurality of training signals. The plurality of training signals are received at a plurality of receivers from a plurality of training tags located in the environment. The environment has a plurality of zones, and each of the training tags is associated with a zone in which it is located. The method further includes generating training data for first and second zones of the plurality of zones, wherein the training data for the first and second zones includes values of the training signals received from training tags located in the first and second zones, respectively, each value associated with the receiver at which a respective training signal was received.

Abstract: The present disclosure is directed to methods for generating a radiofrequency map of an indoor location using LIDAR and Bluetooth sensor fusion. The methods can include fusion of received signal strength indicator (RSSI) data and location data received from devices in an indoor environment. A map of predicted RSSI data corresponding to locations in the indoor environment can be generated based on the fusion of the received data using an artificial intelligence model. The map of predicted RSSI data can then be used to determine the location of devices within the indoor environment.

Abstract: The invention refers to a method for identifying a person (16), comprising the steps of storing information on the identity of the person (16) and/or access authorization data on the mobile device (16) as well as storing biometric data (37) of the person (16) on a mobile device (14) of the person (16); sending the identity information of the person (16) and/or the access authorization data from the mobile device (14) to an authorization device (18); obtaining biometric data (37) of the person (16) by an identification device (20); sending the biometric data (37) from the identification device (20) to the mobile device (14); comparing, only on the mobile device (14), the biometric data (37) from the identification device (20) with the stored biometric data (37) for verifying the identity of the person (16); and sending a confirmation signal from the mobile device (14) to the authorization device (18) if the comparison of step e) verifies the identity of the person (16).
