The invention discloses a method for producing a low ripple coefficient semiconductor super-radiation LED, which is realized by combining a waveguide structure of an oblique triangular absorbing area with an optical anti-reflection film with ultra-low reflectivity deposited on a front cavity surface and a rear cavity surface. In the invention, by adopting the waveguide form of the oblique triangular absorbing area, a certain included angle between three sides and corresponding cavity surfaces is maintained, so that the optical transmissivity can be effectively improved; and in addition, with the oblique cavity structure, the stimulated oscillation can be effectively inhibited and the optical feedback of the cavity surface can be reduced. In the film system design, the influence degrees oflow-reflectivity spectral region bandwidth of two-layer film system structures and refractivity deviation and thickness deviation of a film material on the residual refractivity of the film system are better than that of three-layer film system symmetrical structures; and the allowance for the process preparation is larger so as to facilitate the accurate monitoring. The method for producing the low ripple coefficient semiconductor super-radiation LED, which is provided by the invention, is realized by adopting a relatively-simple process and has lower realization cost and process reasonability.

The invention discloses a method and an apparatus for monitoring a working process of a medical device, and relates to the technical field of medical device monitoring. The method comprises the steps of extracting working parameters of the to-be-monitored medical device through a communication interface of the to-be-monitored medical device; determining function parameters corresponding to detection items of the to-be-monitored medical device according to the working parameters; and according to the function parameters corresponding to the detection items of the to-be-monitored medical device, determining a working state of the to-be-monitored medical device. According to the method and the apparatus, the working state of the small medical device can be accurately monitored, namely, the detection items can be accurately monitored, and for example, the current detection items of the to-be-monitored medical device are monitored; and the medical device is deployed according to usage durations of the detection items of the to-be-monitored medical device, so that the cost is effectively reduced.

The invention discloses a vehicle subsection speed-limiting method based on a vehicle-mounted wireless terminal. A vehicle monitoring platform issues characteristic parameters of road sections to the vehicle-mounted wireless terminal, and the vehicle-mounted wireless terminal receives and stores the characteristic parameters. When a vehicle runs, the real-time position of the vehicle is positioned through the vehicle-mounted wireless terminal, the characteristic parameters in a storage device are called for being compared with real-time position information of the vehicle, and the road section where the vehicle-mounted wireless terminal is located is judged. The current speed of the vehicle is compared with the speed-limiting value of the road section where the vehicle is located, whether the vehicle is overspeed or not is judged, and overspeed information and position information of the vehicle-mounted wireless terminal are reported to the vehicle monitoring platform if the vehicle is overspeed. According to the vehicle subsection speed-limiting method, the characteristic parameters of the road sections are issued to the vehicle-mounted wireless terminal in advance to be stored, when the vehicle runs, only the stored characteristic parameters are required to be directly called for being compared with the real-time longitude, the real-time latitude and the real-time speed of the vehicle, vehicle overspeed monitoring on different road sections at any time can be accordingly achieved, influences of network signals are avoided, and accurate monitoring on the different road sections can be achieved.
