Abstract: Embodiments of this application provide a communication method and an apparatus, to ensure a multicast service data packet transmission security requirement. An access device may determine a user plane security active state of a multicast DRB in a PDU session, and indicate the user plane security active state of the multicast DRB to a terminal, where the user plane security active state includes whether integrity protection is activated and/or whether confidentiality protection is activated.

Abstract: A graph tracks the lineage of customer data, including when it was originally extracted from a customer computing system, and any transformation results indicating transformations that were performed on the customer data. The graph is traversed to identify nodes in the graph that have expired based upon data removal policies. The customer data represented by the expired nodes in the graph is deleted and the graph is modified to delete the expired nodes. The modified graph is then stored in persistent memory until data removal is next triggered.

Abstract: Estimating a three-dimensional (3D) pose and shape of an articulated body mesh is useful for many different applications including health and fitness, entertainment, and computer graphics. A set of estimated 3D keypoint positions for a human body structure are processed to compute parameters defining the pose and shape of a parametric human body mesh using a set of geometric operations. During processing, 3D keypoints are extracted from the parametric human body mesh and a set of rotations are computed to align the extracted 3D keypoints with the estimated 3D keypoints. The set of rotations may correctly position a particular 3D keypoint location at a “joint”, but an arbitrary number of rotations of the “joint” keypoint may produce a twist in a connection to a child keypoint. Rules are applied to the set of rotations to resolve ambiguous twists and articulate the parametric human body mesh according to the computed parameters.

Abstract: An example system comprises first circuitry (such as a first integrated circuit device having a limited number of input/output pins) and second circuitry (such as a second integrated circuit device having a limited number of input output pins). The second circuitry is communicatively coupled to receive communications over a communication link from the first circuitry. In one embodiment, the first circuitry includes a monitor circuit. The monitor circuit monitors a voltage rail inputted to power the first circuitry. The monitor circuit initiates switching between transmitting a control signal (such as status information indicating whether the first circuitry is powered correctly) and a data signal over a communication link from the first circuitry to second circuitry depending upon the magnitude of the voltage rail. For example, when the first circuit is properly powered, the monitor circuit initiates transmission of the data signal over the communication link to the second circuitry.
