    Abstract: Methods and compositions are disclosed to quantitatively measure in vivo blood vessel diameter, blood velocity, and other flow dynamics. Such methods and compositions can optimize therapeutic interventions designed to prevent or reduce the risk of cardiovascular and blood disorders. In one aspect, the methods and apparatus involve calculating blood vessel characteristics from a two dimensional image of a blood vessel in the conjunctiva of a subject's eye. In another aspect, a series of temporal images of a blood vessel are obtained to determine blood flow properties. The apparatus can include, for example, a biomicroscope, an illuminating light source and a high speed camera to acquire the series of temporal images with the data then analyzed by a programmed processor.

    Abstract: A linearizing correction unit (104) carries out a linearizing correction process on the output of an image sensor (8) based upon linearizing correction data stored in a linearizing correction data holding unit (102), and a light-irregularity correction unit (108) carries out a light-irregularity correction process on the image sensor output that has been subjected to the linearizing correction process based upon light-irregularity correction data stored in a light-irregularity correction data holding unit (106). A refection factor calculation unit (110) calculates an integral value of the in-plane reflection factor of a test piece by using the output that has been subjected to the linearizing correction and light-irregularity correction with respect to pixel outputs of the image sensor (8) obtained when the test piece having in-plane density irregularities is measured. A quantifying unit (114) applies calibration curve data of a calibration-curve-data holding unit (112) to the integrated reflection factor obtained by the reflection factor calculation unit so that a sample density of the test piece is calculated.

    Abstract: Above a measuring object (2), an LEDs (4) for use in light irradiation and a CMOS area sensor (8) with an image-forming lens (6) interpolated in between are installed. In order to detect the quantity of light from the LEDs (4), a photodetector (10) is further placed. A personal computer (28) carries out a linearizing process which, upon variation of the quantity of light, corrects the output of the area sensor (8) so as to make the output from the area sensor (8) proportional to the output of the photodetector (10), and a light-irregularity correction process which, when a flat plate having even in-plane density is measured as the measuring object (2), corrects the resulting output of each pixel in the area sensor (8) that has been corrected by the linearizing process to have in-plane evenness. It becomes possible to achieve a convenient two-dimensional reflection factor measuring method which does not need any mechanical driving system.

    Abstract: The purpose of the invention is to properly determine the replacement time of a guard window of an arc sensor using an original function of the arc sensor.The apparatus for monitoring a guard window of an arc sensor according to the present invention is provided with an arc sensor guard window (28) mounted on an arc sensor unit (20) and a standard reflecting plate (30) located at a position a determined distance from the front surface of the guard window (28). And the apparatus detects the reflected light (27) from the standard reflecting plate (30) when a laser beam (26) scans the standard reflecting plate (30), before the guard window (28) is used for an arc welding operation. The apparatus memorizes the quantity of detected light reception as the first quantity. The apparatus then detects the reflected light (27) from the standard reflecting plate (30) in the same way as before, after the guard window (28) is used for an arc welding operation. The apparatus memorizes the quantity of detected light reception as the second quantity of detected light reception as the second quantity. Based on the difference between the first quantity and the second quantity, the condition of the guard window (28) is checked and it is determined whether or not the guard window (28) should be replaced.

    Abstract: A method for automatic particle size analysis of a particle mixture by linear, optoelectronic scanning of a separated particle stream. Particle chord length categories are counted and converted to a particle size distribution. The method takes into account practical considerations such as mixed particle velocities and mixed grain shapes. The exposure time for the linear scanning determines, as a function of the diameter and the velocity of the smallest particle being measured, the number of particles per category size by means of appearance probabilities of recorded chord lengths for corresponding particle sizes. The determination of particle numbers is made using the sequence of the category of the largest particle diameters to the category of the smallest particle diameter, whereby, after each calculation of a particle size category, the number of chord lengths in the length category is corrected.
