An insulated glazing unit has controllable radiation transmittance. Peripheries of first and second glazing panes are attached and spaced apart facing each other and then attached to a supporting structure. A conductive layer is atop the first glazing pane inner surface as a fixed position electrode. A dielectric is atop the conductive layer. A coiled spiral roll, variable position electrode is between the first and second glazing panes, a width of its outer edge attached to the dielectric. A first electrical lead is connected to the variable position electrode's conductive layer. A second electrical lead is connected to the conductive layer atop the first glazing pane. Applied voltage between the first and second electrical leads creates a predetermined potential difference between the electrodes, and the variable position electrode unwinds and rolls out to at least partially cover the first glazing pane, at least reducing the intensity of passing radiation.

To protect tissue in the treatment of an eye (3) with a focused pulsed laser beam (21) generated by a laser system (2), e.g. a femtolaser system, operating data which define an operating area operated on by the focus (F) of the laser beam (21) during the treatment are acquired in a device (1). The device (1) comprises a processing module (14) for providing control data for the laser system (2) on the basis of the operating data and taking into consideration the light propagation in the eye. The control data limit the time of the treatment by the focus (F) at positions within the operating area in each case in such a manner that tissue damage resulting from the treatment by the laser beam (21) is essentially prevented in eye structures located outside the operating area. In particular, the control data determine movements of the focus (F) within the operating area and / or the activity of the laser beam (21) in such a manner that the mean irradiation intensity is reduced and the maximum temperatures in the tissue of eye structures located outside the operating area, particularly in the iris and the retina, are reduced.

The present invention relates to a semiconductor processing system that employs infrared-based thermopile detector for process control, by analyzing a material of interest, based on absorption of infrared light at a characteristic wavelength by such material.

The linear transmission path reduces the risk of signal loss during transmission of the infrared light. The transmission path of the infrared light may comprise a highly smooth and reflective inner surface for minimizing such signal loss during transmission.

In an X-ray diffraction method using the parallel beam method, an X-ray parallel beam (24) is incident on a sample (26), and diffracted X-rays (28) from the sample (26) are reflected at a mirror (18) and thereafter detected by an X-ray detector (20). The reflective surface (19) of the mirror (18) has a shape of an equiangular spiral that has a center located on the surface of the sample (26). A crystal lattice plane that causes reflection is parallel to the reflective surface (19) at any point on the reflective surface (19). The X-ray detector (20) is one-dimensional position sensitive in a plane parallel to the diffraction plane. A relative positional relationship between the mirror (18) and the X-ray detector (20) is determined so that reflected X-rays (40) from different points on the reflective surface (19) of the mirror (18) reach different points on the X-ray detector (20) respectively. This X-ray diffraction method is superior in angular resolution, and is small in X-ray intensity reduction, and is simple in structure.

The present invention is an electronic imaging device and method of expanding its dynamic range. The invention comprises modifying the imaging device by providing a comparator and reset trigger circuit located at or near the site of each of the pixels. The comparator triggers a reset mechanism when the voltage in the charged pixel reaches a reference voltage. During the global exposure time each individual pixel can be self-reset several times, depending on the intensity of the radiation incident upon it. At the end of the global exposure time, each pixel contains only the “residual value” of voltage that remains from the last individual self-reset to the end of the global integration time. An algorithm is implemented, which estimates and determines the number of resets undergone by each pixel during the global exposure time. From this number of resets the algorithm is able to reconstruct the true image. As opposed to prior art methods that make use of pixel reset the device of the invention does not contain electronic components for counting and remembering the number of times that each of the pixels was reset.

A collimator unit includes a filter set for regulating a spectrum of X-rays emitted from an X-ray source, and a source grating having plural X-ray shielding portions and X-ray transmitting portions. The X-ray shielding portions and X-ray transmitting portions extend in a y direction parallel to a rotational axis of a rotating anode of the X-ray source, and are alternately arranged in an x direction orthogonal to an optical axis direction (z direction) of the X-rays. The intensity of the X-rays is reduced in the y direction by a heel effect. However, further reduction in the intensity of the X-rays by vignetting does not occur in the y direction. Since the filter set is disposed upstream from the source grating in an application direction of the X-rays, the source grating forms arrayed narrow focuses of X-ray beams from the X-rays disturbed by a filter element.
