Abstract: One example of a flexible battery includes an electrochemical cell layer and a wrapping layer that wraps the electrochemical cell layer. The flexible battery further includes an energy absorbing layer. The energy absorbing layer is located between the wrapping layer and upper and lower surfaces, which are opposite to each other, of the electrochemical cell layer. The energy absorbing layer includes a plurality of supporting parts that protrude outward from the upper or lower surface of the electrochemical cell layer. The plurality of supporting parts are mainly made of a foam material or rubber. For the energy absorbing layer, a lower-modulus buffering layer or an empty part may be further disposed between the electrochemical cell layer and the wrapping layer, to complement a wavy surface of the supporting part to form a flat surface, so as to meet diversified requirements of a wearable device.

Abstract: A key update method, a network device, a system, and a storage medium, applied to a Bluetooth mesh network. The Bluetooth mesh network includes at least two mesh nodes. A configuration node is a mesh node in the Bluetooth mesh network, and the configuration node is configured to configure a network key of the Bluetooth mesh network. The configuration node determines a first mesh node from mesh nodes in the Bluetooth mesh network, where a network key locally maintained by the first mesh node is inconsistent with a current network key of the Bluetooth mesh network. Therefore, the configuration node encrypts the first network key by using a device key of the first mesh node, to obtain a first ciphertext, and sends a first message that carries the first ciphertext, so that the first mesh node obtains the first network key.

Abstract: Described herein is an apparatus having a wireless power receiver comprising a receiver coil used to receive power wirelessly and to communicate wirelessly. The wireless power receiver outputs power to a bus based on the wirelessly received power. The apparatus has an open-loop DC-DC converter and a linear regulator. The apparatus has a controller configured to enable the open-loop DC-DC converter to use the power on the bus to charge a battery. The controller is further configured to control the linear regulator to stabilize a current in the bus at the output of the wireless power receiver to reduce interference to the wireless communication when using the receiver coil to wirelessly communicate from the wireless power receiver to the transmitter of the power while the open-loop DC-DC converter is being used to charge the battery.

Abstract: A flow table management method, devices, and systems. The flow table management method includes: generating, by a software defined network controller, a first flow table entry, where a first field set in the first flow table entry carries an index of an actual value in the first field set, and the first field set includes N fields; and sending, by the software defined network controller, an OpenFlow protocol message to an OpenFlow switch, where the OpenFlow protocol message carries the first flow table entry. The technical solution in the embodiments of the present invention helps reduce a data volume of flow table entries delivered by an SDN controller to an OpenFlow switch, thereby reducing overheads of a control channel to reduce a congestion risk of the control channel, and reducing occupied network processing resources of the SDN controller and the OpenFlow switch to deliver the flow table entries.
