Improved human health monitoring is provided in the context of sensor measurements of typical vital signs and other biological parameters, by a system and method using an empirical model of the parameters and disposed to estimate values of the parameters in response to actual measurements. Residuals resulting from the difference between the estimates and actual measurements are analyzed for robust indications of incipient health issues. Residual analysis is both more robust and more sensitive than conventional univariate range checking on vital signs.

A monitoring device arranged to display a level of consciousness and hemodynamic parameters of a patient for simultaneous viewing. A dependence of changes in the hemodynamic parameters of the patient on the level of consciousness of the patient may be more easily observed using the monitoring device. Correlations between the patient's level of consciousness and the patient's hemodynamic parameters may further be determined and displayed to aid clinicians in estimating any improvement in hemodynamic parameters that may be achieved through manipulation of the patient's level of consciousness, fluid status and drugs.

An image processing apparatus detects one or more subjects set as detection targets from a shot image acquired by imaging. An image pyramid generator generates an image pyramid used to detect the one or more subjects, wherein the image pyramid is generated by reducing or enlarging the shot image using scales set in advance according to the distance from the imaging unit that conducts the imaging to the one or more subjects to be detected. A detection region determining unit determines, from among the entire image regions in the image pyramid, one or more detection regions for detecting the one or more subjects. A subject detector detects the one or more subjects from the one or more detection regions.

A degradation estimation method system of a high voltage battery is provided that detect degradation of a battery. The degradation estimation method includes obtaining, by a controller, information about an input voltage, an input current and an external temperature of a slow charger. The controller is configured to calculate an output power used for charging the battery, based on an input power calculated based on the input voltage and the input current. In addition, the method includes calculating, by the controller, a mean charging current based on the output power and the battery charging voltage and calculating a battery degradation degree based on the mean charging current.

A system including a microscope and an inspection apparatus in which an objective lens having a large numerical aperture is used for detecting a defect existing inside a sample. A light source apparatus produces linearly polarized light. The polarization maintaining fibers optically coupled to the light source apparatus project the linearly polarized light onto the sample surface as an illumination beam of P-polarized light at an incidence angle substantially equal to the Brewster's angle of the sample. The scattered light generated by the defect existing in the sample is emitted from the sample and is collected by the objective lens whose optical axis is perpendicular to the sample surface. Since the illumination beam of P-polarized light is projected at the incidence angle equal to the Brewster's angle of the sample, no surface reflection occurs and it is possible to use the objective lens having a large numerical aperture.
