Abstract: Technologies directed to detecting and controlling different types of ZigBee devices on different ZigBee networks reliably and efficiently. In one method of operating a first device, the method includes detecting first and second Zigbee networks. The method sends a first request to rejoin the first Zigbee network, the first request being encoded with the first network key. While rejoined as part of the first Zigbee network, the method detects a first set of devices part of the first Zigbee network. The method repeats this for a second set of devices part of the second Zigbee network. The method determines, using the device data, a subset of controllable devices located in proximity, and sends a message with the command to each in response to receiving a command. Each message is encoded with a respective network key and a respective link key specified in the device data.

Abstract: A method for preparing a self-supporting substrate includes: preparing a thin film base structure including a first substrate layer, a thin film layer and a second substrate layer stacked in sequence; removing the first substrate layer from the thin film layer; continuing to grow a material the same as that of the thin film layer on a side of the thin film layer far away from the second substrate layer to prepare a thick film layer; and removing the second substrate layer from the thick film layer and remaining the thick film layer. In the method, a thin film may be grown on a substrate that has a larger diameter, and a thinness of the thin film will not cause the thin film and/or the substrate to crack. Therefore, a thin film that has a large diameter may be obtained so as to obtain a large-sized self-supporting thick film substrate.
