A method of generating a digital twin and of using the digital twin to predict activity of an animate subject. The digital twin is generated from at least system model data and movement data. The digital twin can be activated to simulate a specified activity that the subject is performing or will perform. If desired, the subject can be instructed to perform the same activity while wearing at least one wearable sensor, which is applied to the digital twin. Using artificial intelligence techniques, the activity simulation predicts one or more physical outcomes from the activity.

Digital twin for predicting performance outcomes

A method of using a learning machine to provide a biomechanical data representation of a subject based on markerless video motion capture. The learning machine is trained with both markerless video and marker-based (or other worn body sensor) data, with the marker-based or body worn sensor data being used to generate a full biomechanical model, which is the 'ground truth' data. This ground truth data is combined with the markerless video data to generate a training dataset.

A method of synchronizing the transmission and receipt of messages by radios within a wireless communications network. It is assumed that the radios have chip scale atomic clocks, which are externally synchronized, such as by GPS, but only at the beginning of a mission. Each radio defaults to a sleep mode, in which its receive and transmit circuitry is inactive. Each radio stores a channel plan of pre-determined base transmit times, and calculates a worst case time drift between clocks and a propagation delay value between combinations of radios. At each base transmit time, if a radio has an outgoing message to transmit, it subtracts propagation delay from the base transmit time, and transmits only at that time. Also, for each base transmit time, each radio subtracts time drift, thereby determining a receive time window during which it listens for messages from other radios.

Media access control method with time-coherence and deterministic scheduling for wireless communications network

A system and method for providing audio communications for a simulation system. A computer network has a server in data communication with client systems. The server receives audio from a transmitting client. It then executes transceiver models and impairment models, which inject effects of audio communications media and equipment into sampled audio data. The server then delivers the 'impaired' audio to a receiving client.
