Abstract: An interface circuit in a computing device may communicate with user-interface devices using shared slots during time intervals. In particular, the computing device may transmit outgoing messages to the user-interface devices at a first predefined time during sequential time intervals when the user-interface devices transition from a sleep mode to a normal mode. In response, the computing device may receive incoming messages from one or more of the user-interface devices at a second predefined time following the first predefined time during the sequential time intervals. Then, the computing device may transmit a multicast message to the user-interface devices at a third predefined time during the sequential time intervals. In response to the given multicast message, one of the user-interface devices may communicate data to the computing device. Note that, in some instances, a multicast time slot may instead be used to communicate data to one of the user-interface devices.

Abstract translation: 计算设备中的接口电路可以在时间间隔期间使用共享时隙与用户接口设备进行通信。 具体地，当用户界面设备从睡眠模式转换到正常模式时，计算设备可以在连续时间间隔期间的第一预定义时间将输出消息发送到用户界面设备。 作为响应，计算设备可以在连续时间间隔内的第一预定时间之后的第二预定时间从一个或多个用户界面设备接收传入消息。 然后，计算设备可以在连续时间间隔期间的第三预定时间向用户接口设备发送组播消息。 响应于给定的多播消息，用户接口设备之一可以将数据传送到计算设备。 注意，在某些情况下，可以替代地使用多播时隙将数据传送到用户界面设备之一。
