The invention relates to a intraocular lens system having a flexible anterior lens accommodation material behind the lens. The accommodation material may comprise of one or more macromers, which, when polymerized, adjust the properties of the accommodation material. The anterior lens is flexible such that the curvature of the lens changes during accommodation. The anterior lens may be used alone or in combination with a posterior lens.

Systems and devices for dynamically stabilizing the spine are provided. The systems include a superior component for attachment to a superior vertebra of a spinal motion segment and an inferior component for attachment to an inferior vertebral of a spinal motion segment. The interconnection between the two components enables the spinal motion segment to move in a manner that mimics the natural motion of the spinal motion segment. Methods are also provided for stabilizing the spine and for implanting the subject systems.

A spread-spectrum signal comprises a spreading waveform modulating a carrier wave and containing a real linear combination of a first waveform at a first waveform rate and a second waveform at a second waveform rate, the first waveform rate being distinct from the second waveform rate and both waveform rates being distinct and non-zero. The linear combination of the first and the second waveform is modulated with at least one binary sequence comprising a signal identification code.

The invention discloses graphene hydrogel, graphene aerogel as well as a preparation method and an application thereof. The preparation method of the graphene hydrogel comprises the following steps: (1) dispersion liquid of graphene oxide and water-soluble alcohol are uniformly mixed in order to obtain mixed liquor of graphene oxide; wherein mass content of the water-soluble alcohol in the mixed liquor of graphene oxide is 2-95%, that is the mass of the water-soluble alcohol accounts for 2-95% of the total mass of the mixed liquor of graphene oxide; (2) an irradiation reaction is carried out with high energy ray irradiation for the mixed liquor of graphene oxide. The graphene aerogel is obtained by freeze drying or supercritical carbon dioxide drying of the graphene hydrogel. The preparation method has the advantages of simple operation, green and environmental protection, easy reaction conditions, and operation both in anoxic and aerobic atmosphere; the graphene aerogel has high purity, and except carbon and oxygen elements, the aerogel does not have impurity atoms; the aerogel has a porous and uniform structure, and is good for adsorption of organic solvents with a good oil absorption property.

The present disclosure relates to a screenshot method, device and storage medium. The method includes: when the electronic device enters the area screenshot mode, displaying a screenshot frame on the current display interface, wherein the screenshot frame is used to define the The target screenshot area on the current display interface, and the shape of the screenshot frame is adjustable; receive a screenshot instruction; respond to the screenshot instruction, obtain the image in the target screenshot area; save the image in the target screenshot area . Thus, the user can change the shape of the screenshot frame by adjusting the screenshot frame displayed on the display interface. When satisfied with the adjusted screenshot frame, the user can perform an area screenshot operation to obtain a desired picture. In this way, the purpose of the user to take a screenshot of the area according to his own needs and save it can be achieved, which is closer to the needs of the user and provides convenience for the user.
