The present invention employs condensate extraction method specifically to serve as a self-sustained particle cloud manufacturing and delivery system. The condensate is sent to a particle cloud manufacturing system 3described further in the document, which alters the condensate by mechanical, acoustical, electrical or heliodispoay means, or a combination of one or more means, into microscopic particle cloud material 5.
External ambient conditions such as temperature, humidity, and ambient lighting are read by sensors 36and sent to controller 35which interpret the data and instruct particle cloud manufacturing system 3 to adjust the parameters, ensuring an effective invisible to near-invisible screen for imaging.
Like any rear projection system, the images are best seen within 70 degrees to either side. The device can be hung from the ceiling, placed on walls, on the floor, concealed within furniture such as a desk, and project images from all directions, allowing the image can be retracted when not in use.
The M2i model includes a proprietary system, called Heliocast, for interactively controlling the displayed image and drivers for a standard PC.
The Heliodisplay seminar report transforms water into a unique heliodisplay seminar report of fine vapour, suspended in mid-air to create a nearly invisible screen into which any image can be projected. Applications for this technology are wide-ranging, since the displayed image is non-physical and therefore unobtrusive.
Are you interested in this topic. They are more suited for computer graphics than video applications due to the difficulty in capturing suitable natural imagery in 3D. The Heliodisplay transforms ambient air using a proprietary multi-stage system of modifying the optical characteristics within a planar region in which polychromatic light is scattered on this surface such that the image appears visible to the viewer.
The curtain is produced using similar ultrasonic technology as used in foggers and comprises a number of columns of fog. To showcase these various interaction technologies, we’ve developed a number of demo applications that explore many different interface possibilities. Heliodisplay provides a method and apparatus for generating true high-fidelity full color, high-resolution free-space video or still images with interactive capabilities. Like any rear projection system, the images are best seen within 70 degrees to either side.
The particle cloud exhibits reflective, refractive and transmissive properties for imaging purposes when a directed energy source illuminates the particle cloud. These projected images and video are actually two-dimensional but appear 3D since there is no physical depth reference. The moisture film generated by the device captures the light from the projector to allow the images to take shape. The curtain is heliodisplay seminar report using similar ultrasonic technology as used in foggers and comprises a number of columns of fog.
Yet another difficulty that could give an unrealistic appearance to natural images is that of the inability to display surfaces with a non-Lamberrian intensity distribution.
Intersecting light rays from multiple sources further maximize illumination at the intended image location by localizing the sum of illumination from each projection source striking the particle cloud imaging location.
It works as a kind of floating touch screen, making it possible to manipulate images projected in heliodisplay seminar report with your fingers, and can be connected to a computer heliocisplay a standard VGA connection.

A future display might incorporate the best of both worlds: While the Perspecta is currently used mainly for medical and research purposes, the M2 helikdisplay intended primarily for corporate use as a promotional or advertising tool at this stage.
The multiple hliodisplay source of this invention has the capacity to produc e multi-imaging; were discrete images projected from various sources can each be viewed from different locations.
Heliodisplay – Engineering Seminar. Microenvironment 37 functions to increase boundary layer performance between the particle cloud and the ambient surrounding air heliodisplwy creating a protective air current of similar ejection velocity to that of particle cloud 5.
The Heliodisplay uses heliodiwplay additives or chemicals, only plain tap water you can also use distilled water, ionized water or demineralised water if desired. Tweet Share Pin it Comment. The M has a ” diagonal image, equivalent to displaying a large full-body person about 2 meters tall. However, these water screens may be large and look good if viewed from afar and on-axis.
Heliodisplay images appear 3D when viewed from more than a few feet away because there is no physical depth reference.
It has the same basic specifications as the M2 but is said to be much quieter, with improved brightness and clarity and more stable operation with an improved tri-flow system. The then prototype device projected an image in thin air just above it, creating an illusion of a floating hologram.
The M2 projects its For these particle cloud types adaptive or corrective optics allow compensate for variable focal distances for the projection. Heliodisplay images are not holographic although they are free-space, employing a rear projection system in which images are captured onto a nearly invisible plane of transformed air.
No special glove or pointing device is required. The Heliodisplay is interactive, like a virtual touchscreen.
heliodisplwy The airborne film of moisture generated by the device — the black box with the large slot pictured in the foreground — captures the light from the projector to allow the images to take shape.
Press ESC to cancel. Some projection systems changed the operating environment by over-saturating the surrounding ambient air with particulates, such as humidity or other ejected gases. The interactive M2i version includes virtual touchscreen capability. The display can also take on varying geometric shapes, generating particle heliodisp,ay surfaces other than a flat plane, such smeinar cylindrical or curved surfaces.
Dark background emphasizes the contrast of the image and is highly encouraged when designing a location to view the display.
The original M1 units produced by IO2 were advanced prototypes and proof-of-concept, but a few were sold to early adopters through channels such as eBay.
In latea small company from the San Francisco Bay Area demonstrated a unique revolutionary display technology. The on-axis imaging transmissivity of the cloud screen coupled with the multisource projection insure a clear image, regardless of the viewer’s position and compensates for any aberration caused by turbulent breakdown of the cloud.
The M2 is about the size of a tower desktop computer case turned on its side.

The particle cloud is composed of a vast number of individual micro droplets, between microns in diameter, too small to be visible to the naked eye, held together by surface tension.
The system is compatible with most video sources currently heliodisplay seminar report. This finds great application in criminology. The preferred embodiment of the invention extracts moisture from the surrounding air 22 through a heat pump extraction device 1utilizing solid-state components such as thermoelectric TEC modules, compressor-based dehumidification systems or other means of creating a thermal differential resulting in condensation build-up for subsequent collection.
