Automatic injection device

The invention provides an automatic injection device for providing a subcutaneous injection of a substance into a user, comprising: a housing having an open first end and a second end; a syringe movably disposed in the housing, the syringe including a barrel portion for holding the substance, a hollow needle in fluid communication with the barrel portion for ejecting the substance from the syringe, and a bung for sealing the barrel portion and selectively applying pressure to the substance to force the substance through the hollow needle; a plunger for first moving the syringe towards the first end such that the needle projects from the first end and subsequently applying pressure to the bung, the plunger including a rod connected at a first end to the bung, a compressible expanded central portion and a flange between a second end of the rod and the compressible expanded central portion; and a biasing mechanism for biasing the plunger towards the first open end of the housing, the biasing mechanism disposed about the second end of the rod between the flange and the second end of the housing. The present invention also provides methods and kits for using an automatic injection device, and methods and kits for promoting an automatic injection device comprising a medication based on advantageous properties of the device as compared to a pre-filled syringe. The invention also provides methods and kits for training a recipient on use of the automatic injection device.

Teaching method and system based on cross-media dynamic knowledge graph

The invention discloses a teaching method and system based on cross-media dynamic knowledge graph. The method comprises the following steps of constructing the cross-media dynamic knowledge graph; storing entity related information in the knowledge graph, and returning attribute values corresponding to entities through subject knowledge questions and answers; obtaining feedback information of students and knowledge points, calculating the knowledge point recommendation degree and the learning resource recommendation value score, and therefore, constructing a knowledge point recommendation listand a learning resource recommendation list and returning the lists to learners; constructing a course knowledge card; recommending friends, and recommending other users with similar learning progress and learning conditions to the current user. The teaching system comprises a data layer, a data analysis layer, an application layer and a user layer. The teaching method can be realized through a computer-readable storage medium. The problem that in the prior art, a teaching scheme cannot be formulated in a targeted mode according to learning characteristics is solved, the individualized teaching can be achieved, and the teaching level is effectively improved.

Intelligent control method for traffic light at highway intersection

The invention provides an intelligent control method for a traffic light at a highway intersection, and belongs to the technical field of traffic signal light control methods. The intelligent control method comprises the steps of setting a lane and traffic flow detection meter for detecting lane sections of the lane and the traffic flow, setting the traffic light, and setting up an information processor for analyzing and processing the traffic flow and controlling the traffic light. The intelligent control method has the advantages that coexistence of lane blocking and lane idleness is eliminated, and whatever any time periods, any time frames and any reasons, all lane resources of the highway intersection are can be utilized to the maximum extent, intersection traffic efficiency is improved; due to improvement of the traffic efficiency, reactive power consumption of vehicle fuel and energy is reduced to the maximum extent, expenses and time are saved, and waste gas emission is reduced; waiting time for passing of a vehicle driver is relatively reduced in lane sections or time periods with a few traffic flow, impatient emotion of the driver can be effectively relieved, and second rushing, lane rushing and traffic accidents due to the second rushing and lane rushing are reduced.

Power transmission line online fault monitoring method and system

The invention provides a power transmission line online fault monitoring method and system. The method comprises the following steps: integrating operation parameters and environmental parameters of the power transmission line under different faults to form a fault historical database, and constructing a neural network identification model of the power transmission line under different faults according to the fault historical database; collecting operating parameters and environmental parameters of the power transmission line, inputting the operating parameters and the environmental parametersinto the neural network identification model, and analyzing faults of the power transmission line; judging the fault occurrence reason according to the fault analysis result, and carrying out image acquisition on the possible fault points of the power transmission line; and performing feature extraction and analysis on the acquired images, and obtaining fault occurrence points according to analysis results. According to the power transmission line online fault monitoring method and the system thereof, the fault point can be judged at the first time, the fault searching time is shortened, thefault is eliminated as early as possible, the power transmission is recovered, and the power supply reliability is improved.
