摘要： An improved medium access protocol is divided into two tasks: collision avoidance and contention resolution. The purpose of the collision avoidance is to avoid occasional collisions due to the synchronization of channel access among different stations. The purpose of contention resolution is to control the overall sending rate of competing stations when the shared channel is operating at or near its capacity limits, such that excessive collisions can be avoided. Contention resolution methods in accordance with the present invention include a graceful rate control mechanism.
摘要翻译：改进的介质访问协议分为两个任务：避免冲突和争用解决。避免碰撞的目的是为了避免由于不同站之间的信道接入的同步而导致的偶然冲突。争用解决的目的是在共享信道在其容量限制或接近其容量限制时控制竞争站的总发送速率，从而可以避免过多的冲突。根据本发明的争用解决方法包括优雅的速率控制机制。

摘要： Information included within metadata broadcast within an overhead flow of a mobile broadcast network enables receiver devices to determine when metadata updates will occur. The mobile broadcast network can include within metadata messages information related to a time for the next metadata update. Using this information, receiver devices can determine when the next metadata update will occur and de-energize the receiver until that time. Enabling mobile devices to remain de-energized until the next metadata update improves their power efficiency. Synchronizing mobile devices to access the overhead flow for updated metadata reduces the content delivery latency that the system must accommodate, thereby improving system flexibility and bandwidth efficiency. Specify the time of a next metadata update enables the broadcast system to change the rate and timing at which metadata updates are performed.

摘要： A three-dimensional pose of the head of a subject is determined based on depth data captured in multiple images. The multiple images of the head are captured, e.g., by an RGBD camera. A rotation matrix and translation vector of the pose of the head relative to a reference pose is determined using the depth data. For example, arbitrary feature points on the head may be extracted in each of the multiple images and provided along with corresponding depth data to an Extended Kalman filter with states including a rotation matrix and a translation vector associated with the reference pose for the head and a current orientation and a current position. The three-dimensional pose of the head with respect to the reference pose is then determined based on the rotation matrix and the translation vector.
