OLED data glasses developed by German students at the Fraunhofer Institute in Dresden
June 05, 2009 You don’t need to work for the secret service or as a jet fighter pilot to appreciate the sheer convenience – and craftiness – of being able to grab hold of crucial information, without so much as lifting a finger or batting an eyelid. Students at the Fraunhofer Institute in Germany are developing a pair of interactive data eyeglasses that can project an image onto the retina from an organic light-emitting diode (OLED) micro-display, making the image appear as if it’s a meter in front of the wearer. While similar headwear only throws up a static image, the students are working on eye-tracking technology that allows wearers, with just the movement of the eyeball, to scroll through information or move elements about.

While similar headwear – sometimes referred to as head-mounted displays (HMDs) – only throws up a static image, the students are working on eye-tracking technology that allows wearers, with just the movement of the eyeball, to scroll through information or move elements about.

The glasses are designed to provide information to wearers who don’t have their hands free to operate a keyboard or mouse.

Dr Michael Scholles, business unit manager at the Fraunhofer Institute for Photonic Microsystems (IPMS) in Dresden, believes these devices have a ready-made application in the medical field where they could be used to quickly project vital patient information or medical imaging to doctors during a consultation or surgery.

Scholles also sees applications in the construction industry where the glasses could be used to project drawings or installation instructions.

As the image needs to outshine the ambient light to be seen clearly against changing and highly contrasting backgrounds, OLEDs have been used to produce a high-luminance micro-display.

While existing data glasses only display information, the German students are hoping to make the micro-display technology bi-directional and interactive, which will open up new uses, says Scholles. The eye-tracking device the students are working on – which is fitted to the hinge of the glasses – will enable users to influence the content projected by simply moving their eyes or fixing on certain points in the image.

New content can be displayed and menus can be scrolled through or picture elements shifted. According to Scholles, they have concentrated on making the glasses inexpensive as well as small and light – the system’s eye tracker and image reproduction integrated into the CMOS chip measure 19.3mm by 17mm.

The Life of Fire Extinguishers Pressure Contained & Dry Chemicals all over the world…
In structure of Fire Extinguishers there is a top pin to press under by the grips of fire extinguishers which can let the pressurized dry chemicals with Nitrogen gas(normally 7-9kgf/cm2) erupt through the hole inside the valves of fire extinguishers…Originally the Nitrogen gas contains at least 0.3 percent of moisture in its original production and the dry chemicals are covered by silicone in order to prevent moisture penetrating into the dry chemicals. If the dry chemicals touch moisture then the dry chemicals start to cement making ball like clinkers in the cement industries or sand in the beaches.the balls or stiffened dry chemicals are gathering at the outlet of the valves of fire extinguishers and then these ball hinder the sufficient eruption of dry chemicals, even though the dry chemicals are pressurized with Nitrogen gases…
Therefore the life of fire extinguishers all over the world can not exceed two or three years, because of this kind of structural problems of Pressure-contained Fire Extinguishers(Dry Chemical Powder filled)..

【Background Art】

1. Plastics Molding Technologies(Blow, Direct and Injection Molding)

2. Filling Nitrogen Gas(N2) into the Cylinders of Fire Extinguishers

3. Trasparent Plastics and Light Plastics, lighter than Steel Iron or Aluminium or Stainless Steel which are irresistable to the toxic or acid chemicals to be filled together as the Fire Suppression Materials

4. Electric/Lighting Bulbs for Lumination or Lightings to resist high pressure of Nitrogen Gas(N2) to be filled with Fire Suppression Materials

5. Nitrogen Gas(N2) Filling Technology

6. Assembly Technologies for Cylinders and Fire Suppression Materials together with Nitrogen Gas

【Disclosure】 

【Technical Problem】

1. Molding Technologies for making Cylinder Shapes with Poly Carbonate Plastics and Other Plastics for Valves to contain the Fire Suppression Materials of Dry or Wet Fire Suppression Chemicals to resist the inside pressure of Nitrogen gas of approximate 10kgf/cm2(1 Mpa, 10 Bars).

2. Assembling Technologies together with the Plasctic Cylinders and Nitrogen gas and Fire Suppression Chemicals

3. Making Eletric Lighting Bulbs(Balls) to resist the outside pressure of Nitrogen gas of approximate 10kgf/cm2(1 Mpa, 10 Bars).

【Technical Solution】

1. Found out the suitable Poly Carbonate Composition Products to resist the inside pressure of Nitrogen gas to be filled with the Fire Suppression Materials of Dry or Wet Chemicals(AFFF or Halon)

2. Fire Suppression Materials are well known and world wide produced.

3. Poly Carbonate Plastics are now used for Potable Water Containers worldwide and good enough for visibilities and transparency with the temperature range of minus 60 centigrade plus 150 centigrades, even suitable for the use inside fo Microwave Ranges and Elecric Boiling Ovens with good Sanitary characteristics and very hard to be broken for safety of human beings

4. Now some consumers of Automative Vehicles prefer to filling Nitrogen gas into their tyre tubes to cool down the heat of abrasion for safety reasons.

5. No other specials technical solutions are needed for making;

 1). Transparent and Nude Cylinder for Fire Extinguishes, Poly Carbonate or Other Visible Plastics.

2). Plastics Valves for Fire Extinguishers and Sprikler Heads, Transparent or Invisible

3). Lighting Bulbs with Automatic Diffusing Fire Extinguishers

4). Automotive Mist Light Bulbs with Automatic Fire Extinguishers

5). Sign Boards with Automatic Fire Extinguishers

6). Automotive Tyre Tubes with Automatic Fire Extinguishers

【Advantageous Effects】

1. Easy Checks and Maintenances for the status of Fire Extinguishers as the inside Fire Suppression materials can be seen outside and visible and nude to check whether they are stiffened or the gas inside was outgased or not.

2. When the fires are occurred nearby, the Cylinders of Poly Carbonate Plastics will be begun melting or breaking around plus 110 centigrades, and then the inside the Nitrogen gas will diffuse the Fire Suppression Materials inside automatically or with the help of the Lead/Alcohol types of melting Switches, which are very popularly used in Korea or other countries as the Automatically Diffusing Fire Extinguishers, normally hanging under the ceilings of every Boiler Room or Kitchen, operating normally at the 72 Centigrade

3. Without harming or intervening the existing characteristics of each items of above-mentioned six items, the Fire Suppression Function can be added without high costs or complicate production technoloties, and even the additional side effects can be expected due to the Siliconed Nh4h2Ph4 as these are just like the Nano-glass balls.

【Description of Drawings】

No specific Drawings can be explained, as the currently existing items can be used in the same or little modified shape for additional functions of Fire Suppression Materials and Nitrogen gas to be filled together.
