    摘要: Disclosed embodiments include a system and a method for determining intracranial pressure (ICP) of a subject that comprises: (a) applying transcranial Doppler (TCD) to determine the middle cerebral artery (MCA) velocity of the subject and estimating changes in the ICP continuously based on a functional mapping that relates arterial blood pressure (ABP) and cerebral blood flow velocity (CBFV) to ICP, resulting in an estimated ICP trend; (b) generating a flash visual evoked potential (FVEP) on the subject, processing a detected FVEP signal and obtaining an estimated ICP; and (c) combining the estimated ICP trend from TCD CBFV and ABP with the estimated ICP obtained by signal processing of the detected FVEP signal to periodically correct the trend and obtain a non-invasive measure of ICP.

    摘要: The present invention provides a method for producing double-card anti-counterfeit marks with interlock protection based on the technique which combines nuclear technology with computer-generated hologram (CGH) technology and inspecting apparatus for the mark. The invention relates to the technical field of optical information processing in physics. The technical feature of the invention is to insert potential images R,T and matched potential images R',T' in the anti-counterfeit identification marks and in the inspecting identification marks respectively by means of charged particle track image in sampling coincidence with CGH. When R coincides with R', a certain message of genuineness for an identification mark will be shown, and when T coincides with T', different specific information in thousands of ways appears to prove the genuineness of the protected objects. Because of the microscopic characteristics of nuclear tracks and the distribution characteristics of the phase hologram on the frequency spectrum plane, the potential images R,T,R',T', as the information carriers, can't be duplicated and must be coincided respectively, so as to prevent the genuine anti-counterfeit marks from the illegal imitation.
