A computer-implemented method for managing rescue training includes registering a plurality of individuals as potential rescue trainees through a central computer server system, receiving from computing devices that are remote from the central server system information indicative of rate and depth of compression for ones of the potential rescue trainees, and generating comparative data that reflects performance of CPR chest compressions for a first rescue trainee against other rescue trainees. The method also includes providing the comparative data over a network for review by one or more of the rescue trainees.

A voltage is applied across a counter electrode and a working electrode while an oxidant of a redox substance is in contact with the counter electrode and is not substantially in contact with the working electrode, and thereby metal that readily undergoes electrolytic oxidation forming at least part of a surface of the working electrode is oxidized while the oxidant in contact with the working electrode is reduced, such that a current produced upon the oxidation and the reduction is measured. According to the above constitution, while lowering the voltage applied across the working electrode and the counter electrode, a hematocrit value of a blood sample can be measured stably with satisfactory detection sensitivity. This measurement can be carried out, for example, with a sensor chip comprising a working electrode 11, a counter electrode 12, and a blood sample holder 14 in communication with a blood sample inlet 16, wherein a portion 31 of the working electrode 11 is disposed closer to the blood sample inlet 16 than a portion 32 of the counter electrode is, a surface of the portion 31 includes the metal that readily undergoes electrolytic oxidation, and a reagent 13 containing the oxidant is disposed in contact with the portion 32.

An integral microfluidic device includes an alkali vapor cell and microfluidic channel, which can be used to detect magnetism for nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI). Small magnetic fields in the vicinity of the vapor cell can be measured by optically polarizing and probing the spin precession in the small magnetic field. This can then be used to detect the magnetic field of in encoded analyte in the adjacent microfluidic channel. The magnetism in the microfluidic channel can be modulated by applying an appropriate series of radio or audio frequency pulses upstream from the microfluidic chip (the remote detection modality) to yield a sensitive means of detecting NMR and MRI.

An image detector is for detecting electromagnetic radiation, in particular X-ray radiation. It includes a carrier layer and a photosensor carried by the carrier layer. Each of the carrier layer and photosensor both have a nonvanishing transparency to the electromagnetic radiation. The image detector includes two or more carrier layers and photosensors carried thereby, arranged one above the other, so that the electromagnetic radiation can pass through them one after the other.

A composition, method, and test device for quantitatively determining the oxidant concentration of a test sample are disclosed. The test device includes a test pad having a suitable carrier matrix incorporating an indicator reagent composition capable of interacting with an oxidant to produce a detectable and measurable response for oxidant over a wide concentration range of oxidant. An indicator reagent composition contains: (a) an iodide salt, (b) a buffer, and (c) a water-soluble polymer, preferably a cellulose-based polymer. An indicator reagent composition is incorporated into a carrier matrix, like filter paper, to provide a test pad useful in a dry phase oxidant assay of a test sample, especially for test samples containing a high concentration of oxidant, like chlorine or a peroxide.

Microwave examination of individuals is carried out by transmitting microwave signals from multiple antenna locations into an individual and receiving the backscattered microwave signals at multiple antenna locations to provide received signals from the antennas. The received signals are processed to remove the skin interface reflection component of the signal and the corrected signal data are provided to a hypothesis testing process. In hypothesis testing for detecting tumors, image data are formed from the test statistic used to perform a binary hypothesis test at each voxel. The null hypothesis asserts that no tumor is present at a candidate voxel location. The voxel threshold is determined by specifying a false discovery rate to control the expected proportion of false positives in the image. When the test statistic value associated with a voxel is greater than the threshold, the null hypothesis is rejected and the test statistic is assigned to the voxel. For voxels where the test statistic falls below the threshold, the null hypothesis is accepted and the voxel value is set to zero. The resulting image indicates the locations or other characteristics of detected tumors.

A capacitance detecting circuit detects, in terms of voltage, change in capacitance at intersections of a plurality of column lines and a plurality of row lines crossing each other. The capacitance detecting circuit includes a column-line driving unit for driving a column line; a row-line selector for selecting a specific row line from the plurality of row lines; and a capacitance calculator for calculating a capacitance at an intersection of the specific row line and the driven column line based on a reference current that flows in relation to a reference capacitance and a current that flows in relation to the capacitance at the intersection.

An electrophotographic photosensitive member is provided which can keep at a minimum the absorption of image exposure light of 380 to 500 nm in wavelength in its surface layer and concurrently can satisfactorily keep electrophotographic properties including resolving power. The electrophotographic photosensitive member has a substrate, and a photoconductive layer and a surface layer in this order provided on the substrate. The surface layer includes an amorphous material composed chiefly of silicon atoms and nitrogen atoms and containing at least oxygen atoms and carbon atoms, and the ratios of the numbers of the respective oxygen atoms, carbon atoms and nitrogen atoms to the total number of oxygen atoms, carbon atoms and nitrogen atoms contained in the amorphous material are each within a specific range.

An electrophotographic photosensitive member is provided minimizing the absorption of image exposure having a short wavelength in a surface layer and keeping good electrophotographic properties including resolving power.

A magnetoresistive film is interposed between domain controlling films in a current-perpendicular-to-the-plane (CPP) structure magnetoresistive element. The domain controlling films designed to establish a first biasing magnetic field of a first intensity across the magnetoresistive film along the front end of the magnetoresistive film and a second biasing magnetic field of a second intensity larger than the first intensity along the rear end of the magnetoresistive film. The second biasing magnetic field serves to establish a single domain property within the magnetoresistive film along the rear end. Although the first biasing magnetic field acts in the same direction as the current field at a position near the front end of the magnetoresistive film, the magnetization is allowed to reliably rotate near the front end. A sensing current having a larger current value can be supplied to the magnetoresistive film. The magnetoresistive film exhibits a sufficient sensitivity.
