Abstract: A femoral trialling kit and method for assessing acetabular cup orientation during a left hip joint surgical procedure and a right hip joint surgical procedure are described. The kit includes a trial femoral head having an inner wall defining a cavity extending along a head axis and a visual alignment guide on an outer surface of the trial femoral head and a trial femoral neck having a taper at a free end, the taper being receivable within the cavity. One of the taper and the inner wall has a first anti-rotation feature and a second anti-rotation feature, the first anti-rotation feature and the second anti-rotation feature being inclined, and the other of the taper and the inner wall has a third anti-rotation feature.

Abstract: A system and method is provided for analyzing media traffic having encrypted application-layer and payload data. The method includes determining from network traffic a media service provided to a network subscriber, application-layer and payload data of the network traffic providing the media service to the network subscriber being encrypted, detecting media traffic within the network traffic providing the media service to the network subscriber, associating application-layer data of the media traffic to a media session, determining a key performance indicator (KPI) associated with the media session, and outputting report data based on the KPI.

Abstract: A device includes an interface to a media session comprising transmission of a stream of one or more media segments having unparseable media containers. The device further includes a bit rate estimation module coupled to the interface, the bit rate estimation module to estimate a bit rate for the media session based on a ratio of a first metric to a second metric, the first metric representing a sum of data lengths of the one or more media segments in the media session and the second metric representing a sum of playback durations of the one or more media segments.

Abstract: Systems and methods for adaptive streaming control include a network, a network device, and a plurality of media clients served by the network. The network device monitors media session conditions for a media session with a media client served by the network and enforces policy on the media session based on the media session conditions. The network device can enforce policy by determining a current estimated media quality of the media session based on the monitored media session conditions, determining a target media quality for the media session, and modifying the media session responsive to a difference between the current estimated media quality and the target media quality exceeding a threshold.
