Elizabeth Tudor’s Domestic Theatricality in the Windows of Kenilworth Castle

This paper proposes capabilities of transparent glass window design with energy-saving and heat insulation for carbon reduction issues. An optical thin film coating technology is used for coating multilayered dielectric materials on the transparent glass to achieve an infrared ray shielding effect; especially to prevent rising temperature easily of indoor room. That is infrared ray incidence from outdoor and the thermal flux effect of the transparent window influent the indoor room temperature. In winter, the outdoor temperature is increased more easily by infrared ray incidence. However, the heat insulation window allows 98% of visible light penetration through the window and also allows 90% of infrared light reflection and roughly 10% of infrared light penetration into indoor.

The solar dryer consists of transparent glass window, tray, solar photovoltaic fans and solar panel. The solar radiation passes through the transparent glass window, located on the top of the cabinet. The cabinet is made of anti-corrosive material and of modular nature to meet the varying sizes and loading capacities of food products, ranging from 7 to 8 kg. The ambient air enters from the bottom of the cabinet and gets heated up with solar radiation incident from the top window. The heat energy is trapped in the cabinet and heats up the air. The hot air passed through the trays, carries the moisture from the product to the space below the glass. Then it is exhausted by Solar Photovoltaic Fans. The forced circulation of air in the cabinet is achieved through this solar fan. Assessment of the dryer showed a raised temperature of about 470c attainable in the drying chamber. The dryer temperature and drying rate was found to be higher than the natural open sun drying method. The dryer was able to reduce moisture content of tomato from initial moisture content of 93 per cent wet basis to 4 per cent in three days with effective drying time of 24hr and drying rate of 0.03833 kg/hr, whereas the traditional sun drying was able to reduce moisture content of tomato from initial moisture content of 93 per cent wet basis to 4 per cent in five days with drying time of 34hr and drying rate of 0.0272 kg/hr. The results showed a considerable advantage of solar dryer over the traditional open sun drying method in term of drying rate and less risk for spoilage.

Window signage or signs are cost‐effective ways to attract attention from streets. Assume that you draw something on a transparent glass window. It is difficult to understand your drawing correctly since one observes the mirrored text and graphics from opposite side. The authors dislike this mirrored imaging problem, although it is not a fatal defect. This paper shows a one‐way observable imaging display on the glass window using dye‐doped thin resin layers for unidirectional color generating by light controls and material development. The authors developed one‐way observable window signage display systems which are composed of dye‐doped thin resin films cut for letterings and graphics or dye‐doped resin inks for hand‐drawings.

Suppose that you look Arabic numerals on transparent glass windows or in the air. Which does it mean '85' or '28'? You end up watching the mirrored images when you view from back side. This is the problem to be solved for air floating image or aero signage that is our research target. In 2018, our research group had solved this problem in glass windows. But observers could not freely pass through images although they appear to be floating in the air. In this paper, the authors describe optical elements for aerial display system using hard candy or thin films made from boiled down sugar with water which will harden and can keep its shape.

Suppose that you look Arabic numerals on transparent glass windows or in the air. Which does it mean ‘85’ or ‘28’? You end up watching the mirrored images when you view from back side. So let us make the mirrored image invisible. This paper shows a one‐way observable display for aero signage whose images are floating in the air. To solve mirrored image problems of an aero signage, our research group has utilized dye‐doped prisms and total internal reflection in optics. You know that water is generally colorless and transparent but the water in a bath tub is little blue. The color changes depending on the depth of water. The deeper, the darker water becomes blue. This is the reason why some color is generated in the dye‐doped material. In 2021, we presented a one‐way observable display using letterings made by intaglio printings for arranging dye‐doped tiny prisms on a glass window. You can watch these colored letterforms from front and transparent pixels from back. But this 2021 model has a little defect that colors are less vivid because of color generating mechanism using transparent materials for one‐way observing. In this paper, the authors show special designed optical prisms which are doped with dye and pigments to avoid the semitransparent problem that means colors are not vivid.

But this 2021 model has a little defect that colors are less vivid because of color generating mechanism by twice reflection in conventional optical prisms using transparent materials for making transparent from back side. In this paper, the authors show an aero signage display using dye‐doped corner cube prisms which can lengthen light paths in the prism by multi‐times reflections to avoid the semi‐transparent problem which means colors are not vivid.

Our research group has been developing an aero signage display. The word ‘aero’ means that its image is floating in the air. The authors have noticed that the important technology in aero signage is ‘transparent.’ Suppose you find out window decals which are put on the glass window of shops. You end up watching the mirrored images if you watch the decals on transparent glass window from inside of the shop. In aero signage, the technique which enables to display unidirectional (or one‐way) observable image(viewing angle control) is very important. Our proposed self‐assembly joint mechanism is one of the essential technology for aero signage which enables to make transparent view from back side.

This paper shows a one‐way observable display for aero signage whose images are floating in the air. To solve mirrored image problems of an aero signage, the authors have utilized dye‐doped prisms and total internal reflection in optics. You know that water is generally clear and transparent but the water in a bath tub is little blue. The color changes depending on the depth of water. The deeper, the darker water becomes blue. This is the reason why some color is generated in the dye‐doped material. The authors put the letterings made by intaglio printings for arranging dye‐doped tiny prisms on a glass window. You can watch these colored letterforms from front and transparent pixels from back. Moreover the authors discuss a one‐way observable edgeilluminated window signage display which enables us to observe light emitting signs in the dark night without requiring external illuminating lights.

Pressure shock wave is created in a shock tube which ends with visualization chamber with two transparent glass windows. Different kinds of obstacles to the shock wave are placed in the chamber. Double-exsposure holographic interferometry realized by a Q-swit-ched ruby laser is applied to investigate the events happening in the chamber. Some preliminary results of experiments are presented in the report.

We describe the evolution of the novel shared drawing medium ClearBoard which was designed to seamlessly integrate an interpersonal space and a shared workspace. ClearBoard permits coworkers in two locations to draw with color markers or with electronic pens and software tools while maintaining direct eye contact and the ability to employ natural gestures. The ClearBoard design is based on the key metaphor of “talking through and drawing on a transparent glass window.” We describe the evolution from ClearBoard-1 (which enables shared video drawing) to ClearBoard-2 (which incorporates TeamPaint, a multiuser paint editor). Initial observations and findings gained through the experimental use of the prototype, including the feature of “gaze awareness,” are discussed. Further experiments are conducted with ClearBoard-0 (a simple mockup), ClearBoard-1, and an actual desktop as a control. In the settings we examined, the ClearBoard environment led to more eye contact and potential awareness of collaborator's gaze direction over the traditional desktop environment.

This paper introduces a novel shared drawing medium called ClearBoard. It realizes (1) a seamless shared drawing space and (2) eye contact to support realtime and remote collaboration by two users. We devised the key metaphor: “talking through and drawing on a transparent glass window” to design ClearBoard. A prototype of ClearBoard is implemented based on the “Drafter-Mirror” architecture. This paper first reviews previous work on shared drawing support to clarify the design goals. We then examine three methaphors that fulfill these goals. The design requirements and the two possible system architectures of ClearBoard are described. Finally, some findings gained through the experimental use of the prototype, including the feature of “gaze awareness”, are discussed.

Optical imaging of the functional architecture of cortex, based on intrinsic signals, is a useful tool for the study of the development, organization, and function of the living mammalian brain. This relatively noninvasive technique is based on small activity-dependent changes of the optical properties of cortex. Thus far, functional imaging has been performed only on anesthetized animals. Here we establish that this technique is also suitable for exploring the brain of awake behaving primates. We designed a chronic sealed chamber and mounted it on the skull of a cynomolgus monkey (Macaca fascicularis) over the primary visual cortex to permit imaging through a transparent glass window. Restriction of head position alone was sufficient to eliminate movement noise in awake monkey imaging experiments. High-resolution imaging of the ocular dominance columns and the cytochrome oxidase blobs was achieved simply by taking pictures of the exposed cortex when the awake monkey was viewing video movies alternatively with each eye. Furthermore, the functional maps could be obtained without synchronization of the data acquisition to the animal's respiration and the electrocardiogram. The wavelength dependency and time course of the intrinsic signal were similar in anesthetized and awake monkeys, indicating that the signal sources were the same. We therefore conclude that optical imaging is well suited for exploring functional organization related to higher cognitive brain functions of the primate as well as providing a diagnostic tool for delineating functional cortical borders and assessing proper functions of human patients during neurosurgery.

In this work, we report a contactless temperature measurement method based on the photoluminescence (PL) of an AlInGaP light-emitting diode (LED) structure under open-circuit conditions. The proposed method has been evaluated between 90 and 460 K, but a broader temperature range is possible. The system is based on the temperature-dependent PL variation of a commercial AlInGaP LED designed to emit at 630 nm at room $T$ . The sample is placed inside a temperature-controlled cryostat equipped with a transparent glass window. After exciting the sample by means of a green 532-nm laser, the emitted PL spectrum has been collected by an optical fiber and acquired by means of a charge-coupled device (CCD) array spectrometer. In the first part of the work, the most effective calibration is discussed as a function of the properties of the sampled spectrum; both PL emission peak and spectral width have been considered to calculate the optimal estimated temperature. The effect of spectrometer resolution on temperature estimation has been evaluated by comparing and analyzing the results from two spectrometers with different pixel densities. The effects of excitation intensity and angular positioning have also been evaluated. Finally, uncertainty due to calibration, together with measurement accuracy and precision, has been calculated over 50 acquisitions resulting on average in ±1, ±0.7, and ±0.3 K, respectively, on a temperature range of 300 K.
