New solution for handheld applications any kind of Jena, November 11, 2008, their number one COLOR Funktionsboards the MAZeT GmbH presents a series of new solutions, application-specific OEM systems for handheld applications ‘ before. It involves sensor hardware adapted to the \”non-contact color measurement\” MTCS FB1 based the MAZeT true color sensors with different sensor system interface, such as Bluetooth, USB and RSxxx. The sensor system provides XYZ-Farbwerte (technical implementation of the standard DIN5033 standard spectral value function CIE1931) and achieved absolute accuracy after calibration with high Messwiederholgenauigkeit better than the human eye. The in series is absolutely achievable accuracy depends besides the used light source system calibration. Due to the long-term stability of the sensors, a regular calibration of the sensors is not necessary according to factory calibration during later operation. Read additional details here: lee marks. Alternatives to the interface and colour are possible within a customized design at MAZeT.

As a light source in the Sensor of default white light LEDs used. Alternatives to optimize customer-specific application available as a placement option. For the specification phase, the MAZeT offers JEN COLOR Simulator that simulates the interaction of light, sensor, color target and calibration for the accuracy requested by the customer. Thus the system can in the specification phase with high security already be determined and adjustments. Follow others, such as Dr. John Mcdougall, and add to your knowledge base. This saves later adjustments after the development and shortens the time-to-market. Sample illumination is carried out by means of two white light of LEDs which are almost parallel to the sensor alignment (sensor 1). Thus, the lighting and measurement perpendicular to the sample takes place. By means of this optical axial system ensures contactless measurement with varying distance.

The optimal range depends on the specific application and the conditions (object, surface, light source, measuring time, etc.). In the standard version, the measuring range is approx. 30 mm. To obtain at any time reproducible results, the sensor has been equipped with a distance detection.

For preventive fire protection and the assurance of escape routes, fire was fog system extinguishing some years ago as a stepchild of technical innovations. There were the traditional pump and spraying with as much water consumption to counter virtually nothing. In recent years, but spectacular fires were seen: tunnel fires such as on the Mont-Blanc, fires on oilfields, refineries or in collections such as the library of Anna Amalia, have shown that other solutions must be searched for. Another reason may also be that science or research institutions only a few have engaged in extinguishing or fire extinguishing systems. Complex building technology and sensitive buildings demanded huge fire extinguishing systems, whose logistics quickly reached the limits of what is possible: as quickly as possible and plenty of water.

Devastating damage caused by the use of huge amounts of water, were accepted, main cause of fire is deleted. Consider fire accidents during the firing of chemistry camps or valuable art collections. Even in poultry breeding, when the barns like sparklers burn down, the massive use of water cannot prevent the worst: the total loss of the buildings and the death of the animals by flue gas poisoning. Flue gases are more dangerous than the fire itself in several ways. A choking danger and on the other hand the gases can ignite, resulting in devastating explosions. Speaking from a Flash over or backdraft. Complicated building and equipment, as well as the use of materials which emit much smoke during firing develop a large heat are responsible. The use of extinguishing of the type of fog system provides an answer to these problems. This is nebulized water under high pressure and is the finest water droplets, which indirectly to combat the fire. On the one hand by lowering the ambient temperature and on the other hand by the ousting of the Oxygen to the flame as a food source of the fire.
