Systems and methods are provided for receiving a first message associated with a first sponsor and a second message associated with a second sponsor for inclusion in a message collection. The systems and methods determine a first priority parameter associated with the first message based on sponsored content, and a second priority parameter associated with the second message based on sponsored content. Based on a determination that there is insufficient message inventory to include both the first message and the second message in the message collection, the systems and methods prioritize the first message associated with the first sponsor in the message collection and excluding the second message associated with the second sponsor in the message collection, based on an amount of consideration associated with the first priority parameter received from the first sponsor and an amount of consideration associated with the second priority parameter received from the second sponsor.

Methods and systems are described for preparing a node-enabled shipment of an item to be shipped using a wireless node network having at least a node and a server. A user access device, such as a laptop computer, smartphone, or tablet, may capture an identification of the node to be related to the item. The user access device enters shipping information related to the item and linked with an identification of the node. The shipping information is stored on the node, and then the node is combined with the item to be shipped. A system may include a node and a server, where the node is specially-adapted via programming to emit the identification of the node to the user access device, receive shipping information from the device, store the shipping information on the node, and then upload the shipping information to the server.

Methods and systems are described for monitoring a piece of equipment using a node network having multiple nodes and a server. A second node is associated with the equipment, can monitor equipment operations, and communicate directly with a first node but is unable to directly communicate with the server. The first node can directly communicate with the server and separately communicate with the second node. The first node associates with the second node when the first node detects a signal broadcast from the second node. The second node detects an actionable event related to the operation of the equipment, and transmits a message reporting the actionable event to the first node. The first node notifies the server about the actionable event. Thereafter, the server initiates a responsive action based upon the notification.

A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

Embodiments of the present disclosure provide a method and device for generating a video file, a computer apparatus, and a storage medium. The method includes: obtaining a video-recording instruction, and recording a current picture on a recording interface according to the video-recording instruction; scanning an audio stream broadcasted to a predetermined channel by an audio device; in response to the scanned audio stream meeting a predetermined condition, determining the scanned audio stream to be a target audio stream, and displaying prompt information on the recording interface; and in response to receiving an operation of selecting the target audio stream according to the prompt information, combining the selected target audio stream and the recorded current picture to obtain a video file.
