Abstract: Various approaches enable a computing device (e.g., mobile phone, tablet computer, etc.), serving as a client to inform a group owner (GO) of a peer-to-peer (P2P) group in a Wi-Fi Direct network or other such network regarding the timing of the group owner's beacon schedule. Advantageously, this synchronization of the beacon schedule between the client and the GO can enable improved throughput and latency of the client device when the client device is in concurrent mode (i.e., when the P2P client is connected to two networks such as a legacy Wi-Fi network with an AP and a P2P network with a GO).

Abstract translation: 各种方法使得作为客户端的计算设备（例如，移动电话，平板计算机等）能够通知Wi-Fi直接网络中的对等（P2P）组的组所有者（GO），或者 关于组所有者的信标时间表的定时的其他这样的网络。 有利的是，当客户端设备处于并发模式时（即，当P2P客户端连接到两个网络，例如传统的Wi-Fi）时，客户端和GO之间的信标调度的这种同步可以实现客户端设备的吞吐量和等待时间的提高， Fi网络与AP和具有GO的P2P网络）。

Abstract: Automated tray handling systems and methods may include robotic systems having various end effectors to move trays relative to item sortation systems. For example, the robotic systems may include robotic arms and gantry systems. In addition, the various end effectors may include dual end effectors and passthrough end effectors. The dual end effectors may lift, move, and place trays by engaging and clamping onto flanges of the trays. The passthrough end effectors may lift, move, and place trays through an interior of the end effectors by engaging and pulling or pushing flanges, edges, or other surfaces of the trays. The various automated tray handling systems and methods may increase the speed and efficiency of such processes while also reducing or minimizing the space required for such systems.
