Abstract: 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.

Abstract: Devices systems, and methods can characterize an optical surface of an object. A wavefront sensor system focuses light energy propagating from the object to form a pattern on a detector. The system maps the pattern to an array with a transform function such as a Fourier transform. The values of array correspond to characteristic locations and signals in a transform space, for example an intensity of spatial frequency signals in frequency space. The characteristic location and intensity of these signals in transform space are used to measure the optical surface. For example, a characteristic frequency of a spatial frequency intensity peak in Fourier transform space can be used to estimate the location of spots on the detector. Alternatively, the characteristics can be used to the measure sphere, cylinder and axis of a wavefront, wavefront elevation maps and point spread functions, often without locating positions of individual spots on the detector.

In the case of semiconductor mono-crystalline materials, such as silicon, the depth of penetration of a light ray is proportional to its wavelength. Using this phenomenon, the present invention consists of a pixel having three electrodes that can discriminate between the colors red, green, and blue, and thereby reconstruct a color image.

Abstract: A diversity proximity communication system formed on two juxtaposed chips, one having a two-dimensional array of transmit elements, the other having a two-dimensional array of receive elements. The receive and transmit elements need not be aligned and may have nominal alignment of one transmit element overlapping the corners of four receive elements. The elements may be electrical pads capacitively coupled across the interface. Signals of four different multiplexing groups, e.g., time-multiplexed, are supplied to transmitting elements in a 2×2 array. Signals from four receive elements in a 2×2 array are amplified, combined, and demultiplexed for the selected multiplexing group. The gains for the four signals to be combined are differentially controlled to increase the signal-to-noise ratio. The amplification may be determined by the overlap between each of the receive elements and the transmit element of the selected multiplexing group.
