A vertically-integrated greenhouse for growing plants in suspended trays. The design is particularly well-suited for installation in a double-skin façade of a building, or in an interior atrium, lobby, or similar structure. In addition to producing food, plants can reduce building maintenance costs by providing shade, air treatment, and evaporative cooling to building occupants. The vertically-integrated greenhouse involves the use of a dynamic movable array of plant trays as a mechanical shading device. The spacings and arrangements of the trays in the tray suspension system can be adjusted on both a diurnal basis and a seasonal basis to maximize plant light capture and building shading, thereby maximizing crop yield and building energy savings, or for esthetic considerations.

The present invention is a system and method for increasing the value of the audio-visual entertainment systems, such as karaoke, by simulating a virtual stage environment and enhancing the user's facial image in a continuous video input, automatically, dynamically and in real-time. The present invention is named Enhanced Virtual Karaoke (EVIKA). The EVIKA system consists of two major modules, the facial image enhancement module and the virtual stage simulation module. The facial image enhancement module augments the user's image using the embedded Facial Enhancement Technology (F.E.T.) in real-time. The virtual stage simulation module constructs a virtual stage in the display by augmenting the environmental image. The EVIKA puts the user's enhanced body image into the dynamic background, which changes according to the user's arbitrary motion. During the entire process, the user can interact with the system and select and interact with the virtual objects on the screen. The capability of real-time execution of the EVIKA system even with complex backgrounds enables the user to experience a whole new live virtual entertainment environment experience, which was not possible before.

Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and/or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians.

The fingerprint input device includes: a two-dimensional image sensor for picking up a fingerprint image from a fingerprint measured portion of a measurement target finger; and a transparent solid film mounted on an image pickup surface of the two-dimensional image sensor, the fingerprint measured portion being mounted on the transparent solid film when the two-dimensional image sensor picks up the fingerprint image, wherein the fingerprint input device picks up an image of a fingerprint ridgeline portion in the fingerprint measured portion as a light portion, and picks up an image of a fingerprint valley portion in the fingerprint measured portion as a dark portion through an air layer, and a refractive index of the transparent solid film satisfies that contrast of the image is more than a given value.

There is provided An image projection apparatus comprising: a spatial light modulation element that modulates illumination light by switching the display and non-display statuses of the respective pixels based on pulse width modulation driving to perform gradation expression for each pixel; a light source section able to increase and decrease the amount of illumination light output according to an input controlled variable; a light source control section that periodically controls the light amount of the illumination light output from the light source section; and a projection optical section that projects images modulated by the spatial light modulation element, wherein the light source control section selectively controls the light amount of the illumination light output from the light source section by either one of a first mode in which the controlled variable is changed in a first control period that is shorter than the display period for the spatial light modulation element to display the input image information, and a second mode in which the controlled variable is changed in a second control period that is longer than the first control period.

A reflector 3 having a bottom section 4 and a slope section 13 surrounding the periphery of the bottom section 4 is provided, and an LED 5 is mounted on the center of the bottom section 4. A holder section 9 of a light control means 7 is detachably mounted to cover a lens 6 of the LED 5, while a circular plate section 18 of the light control means 7 is provided with a main reflecting section 11 and a reflecting transmission section 12. The main reflecting section 11 is designed to reduce the transmission amount from the LED 5, thereby causing most of the light to reflect on the reflector 3 side. On the other hand, the reflecting transmission section 12 permits a larger amount of transmission than in the main reflecting section 11. In this manner, it is possible to realize substantially uniform brightness in the entire upper section of the reflector 3 by the light transmitted through the main reflecting section 11 and the reflecting transmission section 12 and the light diffusely reflected from the reflector 3.

A lighting system employing a plurality of said fixtures is highly customizable yet has the potential to be pre-aimed and pre-assembled prior to shipping, which reduces the potential for installation error while preserving the customized nature of the fixtures.

A pre-curing viscous solution (precursor solution) is applied to the back surface of a substrate for forming an optically transparent layer principally composed of an inorganic material. The substrate is heated or irradiated with UV light while being pressed with unevenness of a mold. By removing the substrate from the mold, the optically transparent, inorganic material layer principally composed of the inorganic material is formed on the substrate. In this manner, the inorganic material layer with the unevenness is formed on the back surface of the substrate (a light extraction surface) by embossing.

The invention acquires the output efficiency up to 95 percent by the optimization design of parameters of an LLC resonance network, the constant-current-output intelligent dimming unit circuit of the invention increases the mean value of the output current by increasing the duty cycle of an output current when sensing infrared rays of a human body; and otherwise, the constant-current-output intelligent dimming unit circuit decreases the duty cycle of the output current but not decreases the peak value while no body passes by so as to ensure LED luminous power and prevent light from scattering over the ground.
