An on-vehicle audio video control device is provided, which selects a plurality of audio video equipments with a front controller and a real controller, allowing it to select a same source or respective different sources at a front seat and a rear seat. Herein, if an AM / FM switch is selected with a CD changer by the front controller after the rear controller switches to FM1, it is determined whether the rear controller is in radio mode or not. If the rear controller is in radio mode, the front controller is switched to FM1, following FM1 mode on the rear side.

The invention discloses a multi-band high-resolution tomographic imaging device for solar atmosphere based on an adaptive optical system. The multi-band high-resolution tomographic imaging device for the solar atmosphere based on the adaptive optical system is mainly composed of a collimating mirror, a wave front corrector, a shrinkage beam system, a dichroic beam splitter, a shack-hartmann wave front sensor, a fine tracking wave front sensor, a wave front controller, a blue light imaging channel, a red light imaging channel, a near infrared imaging channel and a data storage system. Different bands of sunlight are corresponding to different heights of the solar atmosphere. The multi-band high-resolution tomographic imaging device for the solar atmosphere based on the adaptive optical system realizes the high-resolution tomographic imaging of the solar atmosphere through simultaneously imaging multiple bands of sunlight and using the adaptive optical system to eliminate the influence of atmosphere turbulence on ground-based telescope imaging. The multi-band high-resolution tomographic imaging device for the solar atmosphere based on the adaptive optical system uses the adaptive optical system to guarantee the space definition of images, multiple bands of sunlight enter different imaging channels successively according to the wavelength, and the energy utilization of each imaging channel is improved. The multi-band high-resolution tomographic imaging device for the solar atmosphere based on the adaptive optical system has an important application prospect in the sun observation field and is significant for the solar physics research.

The invention provides a solar multi-conjugate adaptive optical system. The solar multi-conjugate adaptive optical system comprises a lower atmospheric wave front sensor, a middle and upper atmospheric wave front sensor, a lower atmospheric wave front corrector, a middle and upper atmospheric wave front corrector, a wave front controller, an optical relay system, an imaging subsystem and other necessary optical components. The system has the advantages that sunspots or grain structures on the surface of the sun are taken as beacons and wave front detection is conducted on multiple areas at the same time, so as to obtain wave front distortion caused by turbulence in a large field range; wave front aberration caused by different turbulent layers is calculated by utilizing a tomography algorithm; and at last, the wave front correctors positioned in conjugate positions of the corresponding turbulent layers are controlled to correct the atmospheric turbulence in a layered manner, so as to finally realize high-resolution imaging in the large field range. The solar multi-conjugate adaptive optical system has the advantages that the sequence of the conjugate positions of the high and the lower turbulent layers is adjusted through the optical relay system, so that the lower turbulent layer is firstly compensated and corrected and the accuracy of the detection and the correction is increased; and due to the use of the tomography algorithm, errors caused by the coupling of the wave front aberrations of the different turbulent layers are reduced.

The invention discloses an integrated DC / DC (Direct Current) power source front-end control system. The integrated DC / DC power source front-end control system at least comprises an integrated DC / DC power source front-end controller, wherein one integrated DC / DC power source front-end controller works in a main working mode, and other integrated DC / DC power source front-end controllers work in a slave working mode; the integrated DC / DC power source front-end controller working in the main working mode outputs a clock signal to the integrated DC / DC power source front-end controllers working in the slave working mode. The power consumption can be reduced particularly when multiple groups of integrated DC / DC power source controllers compose an integrated power source front-end control system, and resources are saved. Meanwhile, a DC / DC conversion function with different voltage demands is realized through connecting one or more transformers.

The invention discloses an interactive video clipping system and an interactive video clipping method. A pre-controller is arranged at a host terminal and used for controlling a video player to be synchronous with the pre-controller; a video in the video player is loaded and the duration of the video is obtained; clipping, caption inserting or exercise inserting is performed on the video according to an operation of a user, and the video player is controlled to play the clipped, caption inserted or exercise inserted video; online edition of the video is thus realized, and the format and content of the original video are not changed; for playing, the pre-controller is used for achieving the effect of video clipping. The video is enabled to have the interactive function by virtue of caption and exercise insertion, rather than single playing.

The invention discloses a method and a system for information push. The method includes: a front-end controller sends requests to an information management server when detecting mouseover events occur at an information publish position of an internet application interface; the information management server selects information as second information from intrinsic storage according to the requests of the front-end controller and pushes the second information to the front-end controller; and the front-end controller suspends the second information pushed by the information management server above the displayed first information to display the second information. By the method and the system for information push, the problems of single information publish mode and failure in meeting the requirement on publishing of a great amount of information by limited information publish positions are solved.
