Abstract: The present invention relates to a fall detection method, corresponding system and machine, for detecting the fall of a wear element provided with a three-axis accelerometer of an earth moving machine with the following steps: obtaining an accelerometer measurement of each wear element; determining a rotational position measurement of each wear element with respect to the reference axis based on its accelerometer measurement; determining a mean reference value based on all the rotational position measurements; determining a deviation value of each wear element based on the deviation between its rotational position measurement with respect to the mean reference value; determining that there is a fall of a wear element if its deviation value exceeds a threshold value; and repeating the steps in an iterative manner.

Abstract: The present disclosure relates to a method of coordinating personal assistants. The method comprises: sending a request to a set of personal assistants based on a received query. Assistant responses may be received in response to the request from respective personal assistants of the set of personal assistants. Each assistant response of the assistant responses comprises a confidence score of the respective assistant response. The confidence scores may be adjusted to a common scale. The adjusted confidence scores may be weighted using domain-specific weights of the personal assistants in accordance with the domain of the query. One or more assistant responses of the received assistant responses may be selected based on the weighted scores and the selected assistant responses may be provided to the user.

Abstract: A processor instantiates a virtual network function (VNF) and a probe to monitor at least one metric associated with the VNF. The processor also allocates a pool of ports to the probe. A transceiver establishes one or more first interfaces between the probe and one or more applications using one or more first ports from the pool of ports. Information such as metrics generated by the ports is concurrently exchange between the probe and the applications using the first interfaces. In some cases, a second interface is established between the probe and a monitoring server. The probe reports mission critical events to the applications via the first interfaces and non-mission critical events to the monitoring server via the second interface concurrently with reporting the mission critical events.

Abstract: A method provides a set of predicted responses to a user. The method includes receiving a message from a user, the message having natural language information. The method includes processing, using cognitive switching logic (CSL), the natural language information and information from previous messages from the user. The method includes identifying, using CSL, a context of the natural language information based on the information from the previous messages. The method includes identifying, using CSL, at least one knowledge domain which contains a response to the message, based on the identified context and on user persona information. The method includes retrieving a response from each identified knowledge domain. The method further includes, in response to retrieving more than one response, transmitting feedback to CSL to refine identifying the at least one knowledge domain until only one response is retrieved. The method further includes presenting the one response to the user.
