Abstract: A resource selection method includes: A first terminal device determines an initial candidate resource set including M resources, and determines, based on an RSRP and a collision index that are associated with SCI received in a sensing window, whether to exclude an ith resource in the M resources from the initial candidate resource set, to obtain a candidate available resource set. The collision index is an index of a collision between a reserved resource indicated by the SCI received in the sensing window and an ith periodic resource. The ith periodic resource includes the ith resource and a resource obtained after the ith resource is extended based on a preset first period. Herein, M is a positive integer, and i is a positive integer from 1 to M.

Abstract: An air channel arrangement of a tower fan, arranged for accommodating an air blower therein, includes a housing having an air inlet, an air outlet and an air blower installation space therein, a volute shell and a volute member having a curved surface portion, wherein the volute shell and the curved surface portion of the volute member are arranged on two sides of the air outlet respectively such that, when the air blower is driven to rotate, the airflow is guided to flow through the air channel smoothly, so that the tower fan has excellent air supply efficiency and is able to prevent eddy airflow being formed in in the air channel and reduce working noise of the tower fan.

Abstract: A resource processing method includes a first device receiving first sidelink control information (SCI) having first indication information. The first indication information indicates a first time-frequency resource, and the first indication information further indicates the first device to send second SCI. The first device sends the second SCI. The second SCI includes second indication information indicating a second time-frequency resource. The first time-frequency resource is a time-frequency resource reserved for a second device to send data to the first device or a time-frequency resource that is reserved for the second device to send data to the first device and that is reserved for the first device to receive data. The second time-frequency resource is a time-frequency resource reserved for the first device to receive data.

Abstract: A cloud-edge collaborative processing system includes: an edge computing system, an ICU diagnosis and treatment device, a service terminal device, and a cloud platform. The edge computing system collects multi-source heterogeneous medical data output from the ICU diagnosis and treatment devices and performs preprocessing, stores preprocessed data into an edge database, and connects to the cloud platform for data transmission and business interaction. The cloud platform connects to a plurality of edge computing systems to perform computation and processing of massive data. The medical-staff handheld terminals and the data terminals of wards are used to issue service instructions to the cloud platform to obtain the required third-party-business services.

Abstract: Disclosed are a method and system for generating a data analysis report of a multi-parameter monitoring device. The method includes: receiving, by an application server, multi-parameter data transmitted in real time by the multi-parameter monitoring device, and storing the received multi-parameter data in a database server; the application server receiving a report generation instruction transmitted by a client, the instruction including a client identifier used for indicating a permission of the client; if the permission is a first mode permission, transmitting the multi-parameter data to the client, to allow the client to process the multi-parameter data, so as to generate a multi-parameter analysis report and a report attachment; and if the permission is a second mode permission, the application server processing the multi-parameter data to generate the multi-parameter analysis report and the report attachment, and transmitting the multi-parameter analysis report and the report attachment to the client.

Abstract: A method includes a first device that sends a beacon message on a beacon indication resource corresponding to a first resource, where the beacon message indicates that the first resource is used by a device in a first user group and another user group cannot use all or a part of the first resource; or the first device skips sending the beacon message on the beacon indication resource corresponding to the first resource such that a device in the other user group determines that the first resource is not used by the device in the first user group and all or part of the first resource can be temporarily used by the device in the other user group.

Abstract: A first device receives first configuration information used for beam training, and may determine, based on the first configuration information, L codewords associated with M reference signals. The first device may measure the M reference signals, determine V codewords in the L codewords based on a measurement result, and report first indication information indicating the V codewords.
