Aluminum Spiral High Speed Door
The Spiral door offers high-speed operation for high-traffic situations and rigid aluminum slat construction that eliminates the need for a second security door. Crisp lines give the Spiral door a stylish look that's great for many types of commercial, automotive retail, government, institutional and industrial applications. The Spiral is ideal for automotive dealerships, government, parking and security. Benefits No metal-to-metal contact reduces wear on the door panel and offers fast, quiet operation.
Aluminum spiral High Speed doors are usually used wherever goods traffic occurs and where the doors have to fulfill special requirements. In the food and beverage industry, or Medical industry for example, special climatic conditions have to prevail; short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.

In the days before science and technology , graphene flagship project researchers from the ICFO of the Barcelona Institute of Optoelectronics claimed that they can integrate graphene into CMOS integrated circuits. This work was published in "Nature Photonics". The team combined graphene CMOS devices with quantum dots to form an array of photodetectors, producing high-resolution image sensors. When used as a digital camera, the device can simultaneously sense ultraviolet, visible, and infrared light. Scientists say that this is just one example of the possible applications of this device, and it may also be applied to microelectronics, sensor arrays, and low-power photonics.
ICFO's ICREA professor Frank Koppens commented: “The development of this monolithic CMOS-based image sensor is a milestone because they are low-cost, high-resolution broadband and hyperspectral imaging systems. He added: “General For example, graphene CMOS technology will enable a wide range of applications, including security, security, low-cost micro-smart camera cameras, fire-fighting systems, passive night vision and night surveillance cameras, automotive sensor systems, medical imaging applications, and food and drug inspections.

The Graphene Flagship, an international coalition of more than 150 research teams from 23 countries, has developed a high-precision new infrared detector using graphene nanomaterials. According to the team, the new detector detects nano-level variations in thermal radiation - equivalent to one-thousandth of the energy released when the hand gently swings.
The advantage of graphene is its openness in high-performance infrared imaging and spectroscopy. Researchers from Graphene Flagship, from the University of Cambridge (UK), Embry Corporation (UK), Photonics Science Institute (ICFO; Spain), Nokia and Ioannina University (Greece) have developed a graphene-based, Infrared radiation detection is a highly accurate pyroelectric radiation meter for measuring small changes in temperature.
The work published in Nature Communications demonstrates the highest reported temperature sensitivity of graphene-based uncooled thermal detectors, which can decompose temperature changes into tens of μK. Only a few nanometers of IR radiation power is needed to produce such a small temperature change in the isolation device, about 1000 times less than the IR power delivered to the detector by a close-to-close human hand.
The high sensitivity of the detector is very useful for spectral applications beyond thermal imaging. Using a high-performance graphene-based IR detector, it can provide a strong signal with less incident radiation and can isolate different parts of the IR spectrum. This is crucial in safety applications where different materials (eg explosives) can be distinguished by their characteristic IR absorption or transmission spectra.
Dr. Alan Colli, Principal Engineer and Head of Research at Embry, said: "Using more sensitive detectors can limit the large tropics, and still use photons in a very narrow spectral range to form images and do multiple spectra. Infrared imaging has certain signatures for safety inspections, materials are emitted or absorbed in a narrow band, and therefore a detector trained in a narrow band is needed, which is looking for explosives, harmful substances or any sort."
A typical IR photodetector operates by a thermoelectric effect or as a bolometer that measures the change in resistance due to heating. A graphene-based pyroelectric bolometer combines these two methods with the excellent electrical properties of graphene for optimal performance. Graphene as a signal's built-in amplifier eliminates the need for external transistors, which means that there is no loss of parasitic capacitance and significantly lower noise.
The high conductivity of graphene also provides convenient impedance matching with external readout integrated circuits (ROICs) for interfacing with detector pixels and recording devices. With continued improvement in the quality of graphene (eg, higher mobility), robust devices with extended dynamic range (temperature range over which the device will work reliably) can be manufactured while maintaining the same excellent temperature responsiveness.
Professor Andrea Ferrari, director of the Cambridge Graphene Center, said, “This work is another example of the steady progress of graphene in the application roadmap. Embrton is a new company specializing in the production of graphene photonics and electronics. And thermal sensors, this work exemplifies how basic science and technology can lead to rapid commercialization.†Andrea Ferrari is a science and technology officer at Graphene Flagship and chairman of the Graphene Flagship management team.
Prof. Frank Koppens, a collaborator of the project, is the leader of ICFO's quantum nanophotonics technology and leads the Photon and Photonics work package of Graphene Flagship. “One of the most promising applications of graphene is broadband photodetection and imaging. It is impossible to combine visible light and infrared detection in one material system based on any other prior art. Graphene Flagship plans to further develop hyperspectral. The imaging system develops unique directions for graphene,†he said.
Dr. Daniel Neumaier (AMO, Germany) is the leader of the electron and photonics integration department at Graphene Flagship and has not been directly involved in this work. He said: "In the past few years, the market size of infrared detectors has increased dramatically. These devices are being used in more and more applications. Spectral safety inspections are becoming more and more important. This requires high sensitivity at room temperature. The current work is a huge step forward in meeting these requirements for graphene infrared detectors."
