  • Publication number: 20200410736
    Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media for generating a digital animation of a digital animation character by utilizing a generative adversarial network and a hip motion prediction network. For example, the disclosed systems can utilize an unconditional generative adversarial network to generate a sequence of local poses of a digital animation character based on an input of a random code vector. The disclosed systems can also utilize a conditional generative adversarial network to generate a sequence of local poses based on an input of a set of keyframes. Based on the sequence of local poses, the disclosed systems can utilize a hip motion prediction network to generate a sequence of global poses based on hip velocities. In addition, the disclosed systems can generate an animation of a digital animation character based on the sequence of global poses.

  • Publication number: 20200397448
    Abstract: The present invention provides an occluder and a medical device. The occluder comprises: an occluding unit having a remote end and a near end; and a position-limiting unit connected to the remote end and the near end for limiting an extension distance therebetween. The position-limiting unit is connected to the remote end and the near end of the occluding unit to limit the extension distance therebetween, such that the occluder is in an entirely or partially collapsed state when in a sheath, thereby preventing the issue of the occluder occupying an excessive length of the sheath. The occluder is not fully extended while in the sheath, but instead remains in an entirely or partially collapsed state, so as to better maintain the dimensions of the occluder after the same is released from the sheath.

  • Publication number: 20200364608
    Abstract: A computer-implemented method of communicating in a federated learning environment includes an aggregator and a plurality of federated learning participants that respectively maintain their own data and communicate with the aggregator. The aggregator monitors the plurality of federated learning participants for factors associated with stragglers. The federated learning participants are assigned into tiers based on the monitoring of the factors. The aggregator queries the federated learning participants in a selected tier and designates late responders as stragglers. Maximum waiting time may be defined for each tier. The aggregator applies a predicted response for drop outs including collected participants' replies and computed predictions associated with the stragglers to update a training of a federated learning model. The federated learning participants that do not respond within the designated wait time are designated as drop outs.

    Abstract: A vehicle radar system (2) that is arranged to detect a plurality of objects outside a vehicle (1) and that includes a radar detector (3) and a processing unit arrangement (4). The processing unit arrangement (4) is arranged to obtain at least one total detection angle (?dT, ?dT?) relative an x-axis (7) and at least one corresponding detected target Doppler velocity (vDoppler) relative the radar detector (3) for each detected object (5, 6; 10, 11). Each detected object is classified as moving or stationary, and a relation is determined between the stationary detections and the total number of detections. The processing unit arrangement (4) further is adapted to determine whether the radar detector (3) is misaligned based on the relation, where the total detection angle (?dT, ?dT?) equals the sum of a known mounting angle (?m) between the x-axis (7) and the radar detector's mounting direction (8), and a detection angle (?d, ?d?). The present disclosure also relates to a corresponding method.
