摘要： The corneal reflex method is used to detect the current direction of view (VD) of a user (UE) to perform specifically selected functions on a computer. Eye vectors (EV) can be detected between the pupil center (ZP) and reflection points (RP) on the cornea (CA) that can be associated with a fixation point (FP) on a computer screen using infrared light (IRS). The association is produced as a function of the direction of view (VDF), so the relationship is detected during an initial calibration (C) by a referenced user (RE) to develop a set of reference eye vectors (EVR). A shorter self-balancing recalibration (RC) is then carried out for each subsequent user (UE). A mapping function (MF) is detected during the recalibration (RC) so that the individual eye vectors (EVU) can be converted to the reference eye vectors (EVR) by the mapping function. The recalibration (RC) can take place without the user (UE) realizing it. The method is useful in medical diagnostics, psycho-optical examinations and eye-controlled interaction with multimedia computers.

摘要： The present invention discloses a navigation method for electric vehicles based on electricity quantity guidance of energy-storage charging piles. The electric vehicles select charging piles nearby that can meet own charging quantity demands to charge according to location information of charging piles and real-time stored electricity information of energy storage modules of the charging piles; a system using the method includes the charging piles. The navigation method and system can reasonably guide the electric vehicles to charge according to the distribution and the stored electricity of the charging piles, and can dynamically plan travel charging solutions for the electric vehicles, thereby avoiding problems that the electric vehicles stop running without electricity on the way to the charging piles and inefficiently wait for charging for a long time, so that the stored electricity of the charging piles can be reasonably distributed and utilized, and energy idleness and waste are avoided.

摘要： Automation of microscopic pathological diagnosis relies on digital image quality, which, in turn, affects the rates of false positive and negative cellular objects designated as abnormalities. Cytogenetic biodosimetry is a genotoxic assay that detects dicentric chromosomes (DCs) arising from exposure to ionizing radiation. The frequency of DCs is related to radiation dose received, so the inferred radiation dose depends on the accuracy of DC detection. To improve this accuracy, image segmentation methods are used to rank high quality cytogenetic images and eliminate suboptimal metaphase cell data in a sample based on novel quality measures. When sufficient numbers of high quality images are found, the microscope system is directed to terminate metaphase image collection for a sample. The International Atomic Energy Agency recommends at least 500 images be used to estimate radiation dose, however often many more images are collected in order to select the metaphase cells with good morphology for analysis. Improvements in DC recognition increase the accuracy of dose estimates, by reducing false positive (FP) DC detection. A set of chromosome morphology segmentation methods selectively filtered out false DCs, arising primarily from extended prometaphase chromosomes, sister chromatid separation and chromosome fragmentation. This reduced FPs by 55% and was highly specific to the abnormal structures (≥97.7%). Additional procedures were then developed to fully automate image review, resulting in 6 image-level filters that, when combined, selectively remove images with consistently unparsable or incorrectly segmented chromosome morphologies. Overall, these filters can eliminate half of the FPs detected by manual image review. Optimal image selection and FP DCs are minimized by combining multiple feature based segmentation filters and a novel image sorting procedure based on the known distribution of chromosome lengths. Consequently, the average dose estimation error was reduced from 0.4 Gy to

摘要： A system is described comprising a service provider and an identity provider. A user requests access to the service provider and the service provider seeks user credentials from the identity provider. In use, the service provider issues an authentication request, which request specifies details of a plurality of acceptable authentication formats. The identity provider responds to the request either by providing authentication details for said user in one of the formats specified in the request, or by returning an error message indicating that it cannot support any of the specified authentication formats.
