Abstract: An illustrative virtual meeting management system associates a user device of a participant of a virtual meeting with a physical location from which the participant and one or more additional participants participate in the virtual meeting. The virtual meeting management system determines that the participant provides a user input via the user device during the virtual meeting. The user input indicates that the participant will speak. Based on the user input and the associating, the virtual meeting management system provides an active speaker indicator for presentation in a virtual meeting interface provided to one or more participants of the virtual meeting. The active speaker indicator specifies a participant identifier representative of the participant. Corresponding methods and systems are also disclosed.

Abstract: A split control system for UAV incorporating auto pilot is disclosed. Control system comprises a real-time low-level main processor, and a non-real-time high-level co-processor. The co-processor computes desired body rate values and feeds them to the main processor which may be with latency. Main processor computes one or more motor control signals based on the desired body rate values. The main processor also executes a rate damping loop algorithm based on instantaneous body rate values to generate one or more motor control signals to maintain stability of the UAV even in events of latency in desired body rate values from the co-processor. Instantaneous body rate values are either obtained directly from sensors without any latency or obtained by main processor indirectly with negligible latency. Main processor acts as an intermediate between sensors and co-processor by collecting raw sensor data and feeding the data to co-processor.
