    • A tag includes a communication interface that is configured to receive and transmit wireless transmissions, a movement detector and a digital logic circuit configured to perform operations. The operations may include broadcasting wireless transmissions comprising a tag ID of the tag from the communication interface according to a transmission pattern. A stationary movement pattern of the tag may be detected with the movement detector. The operations may further include adjusting the transmission pattern responsive to detecting the stationary movement pattern. A confirmation from a computing device indicating that information for the tag ID has been received by a server tracking the tag. The adjustment to the transmission pattern may also be responsive to receiving the confirmation. The tag broadcasts wireless transmissions according to the adjusted transmission pattern.
    • 标签包括被配置为接收和发送无线传输的通信接口,移动检测器和被配置为执行操作的数字逻辑电路。 操作可以包括根据传输模式从通信接口广播包括标签的标签ID的无线传输。 可以用移动检测器检测标签的固定移动图案。 所述操作还可以包括响应于检测到静止运动模式来调整传输模式。 来自计算设备的确认指示标签ID的信息已被跟踪标签的服务器接收。 对传输模式的调整也可以响应于接收确认。 标签根据调整的传输模式广播无线传输。
