Dynamically controlled permissions for managing the display of messages directed to a presenter
The techniques disclosed herein provide dynamic permissions for controlling the display of messages directed to a presenter of a communication system. For example, during a presentation of an online meeting, a system may selectively permit private messages to be sent to a presenter from designated participants.

The three-phase output voltage is supplied to a three-phase output filter arranged downstream of the electronic switches and coupled to the direct voltage circuit, allowing common mode portions of filter input currents of the output filter to flow into the direct voltage circuit. Filter output currents of the three-phase output filter are controlled in a closed-loop manner, and a zero-system voltage of the filter input voltages of the output filter is controlled in a closed loop manner as a function of a target voltage space vector of the space vector modulation and as a function of the filter input currents to suppress oscillations in a zero system of the filter input currents. |

Distributed computation for real-time object detection and tracking
Techniques for distributed object detection and tracking are described. In an example method, a first current frame from a series of frames is sent to a first node, for detection of a first object. After object detection information for the first object is received in return, a second node is selected, and a second current frame is sent to the second node for an updated object detection. In addition, while waiting for the results of the updated object detection, two or more frames following the second current frame are sent to respective tracking nodes. Object modelling information indicating location and/or classification of one or more objects, as derived from the previously received object detection information is also sent to each of the respective tracking nodes. Tracking information for the first object is received from each of the respective tracking nodes. |
