The invention provides methods and kits for detecting, screening, quantifying or localizing the etiology for reduced or impaired cranial nerve function or conduction or associated cranial nucleus or supranuclear input, useful for detecting, diagnosing or screening for increased intracranial pressure, or useful for detecting, diagnosing, monitoring progression of or screening for a disease or condition featuring increased intracranial pressure by tracking eye movement of the subject. The methods may be performed by a) analyzing eye movement of the subject; b) comparing eye movement of the subject to eye movement of a control or the subject's own baseline eye movement; and c) identifying the subject as having eye movement significantly different from the control or the subject's own baseline eye movement.

The invention provides methods and kits for detecting, screening, quantifying or localizing the etiology for reduced or impaired cranial nerve function or conduction; localizing a central nervous system lesion; detecting, diagnosing or screening for increased intracranial pressure, pressure or disruption of central nervous system physiology as seen with concussion; or detecting, diagnosing, monitoring progression of or screening for a disease or condition featuring increased intracranial pressure or concussion by tracking eye movement of the subject. The invention also provides methods and kits useful for detecting, screening for or quantitating disconjugate gaze or strabismus, useful for diagnosing a disease characterized by disconjugate gaze or strabismus in a subject, useful for detecting, monitoring progression of or screening for a disease or condition characterized by disconjugate gaze or strabismus in a subject or useful for quantitating the extent of disconjugate gaze or strabismus. Further, the invention provides methods for assessing or quantifying structural and non-structural traumatic brain injury or diagnosing a disease characterized by or featuring structural and non-structural traumatic brain injury.

The invention discloses a method and a device for embedding a visible watermark into an image. The method comprises the following steps: after a fundamental region into which each visible watermark is to be embedded is determined in an original image data block, a final region into which each visible watermark is to be embedded is obtained by enlarging the fundamental region; an image data block,into which the visible watermarks are imbedded, is obtained by embedding the visible watermarks into the fundamental region; an additional data block is built according to information about the visible watermarks and information about the final region; and after the additional data block is connected to the image data block into which the visible watermarks are embedded, the embedding of the visible watermarks is completed. Meanwhile, the invention further discloses a method and a device for recovering an original image. By enlarging the fundamental region and building the additional data block, the invention recovers precisely the original image, avoids blocking effect and boundary effect, and avoids visual impact caused by compression. Moreover, the whole method is self-closed, recoversthe original image without requesting extra data, and realizes rapid operation.

The invention belongs to an electric energy quality monitoring technology, particularly a ship electric energy quality monitoring system. The system comprises a data analysis evaluation subsystem and data acquisition processing subsystems distributed on each node. The data acquisition processing subsystems are used for acquiring three-phase voltage and current signals of a ship power grid in real time and providing the three-phase voltage and current signals for the data analysis evaluation subsystem by the Ethernet; the data analysis evaluation subsystem is used for completing calculation of steady-state electric energy quality indexes in an on-line mode and giving an electric energy quality comprehensive evaluation according to an index weight; the detection of transient-state electric energy quality perturbation parameters is completed in an off-time mode; the steady-state electric energy quality indexes comprise a voltage deviation, a frequency deviation, harmonic waves, three-phase unbalance, voltage fluctuation and flicker; and the transient-state electric energy quality perturbation parameters comprise short duration voltage variation, time varying harmonic waves and inter-harmonics. According to the system, all the nodes on the power grid can be simultaneously monitored, the factors influencing the electric energy quality can be analyzed by a plurality of indexes and the level of the electric energy quality of the power grid is timely known.
