EnOcean ECT310
The EnOcean technology is an energy harvesting wireless technology used primarily in building automation systems, but also in other application fields such as industry, transportation, and logistics. The energy harvesting wireless modules are manufactured and marketed by the company EnOcean, headquartered in Oberhaching near Munich. The modules combine micro energy converters with ultra low power electronics and wireless communications and enable batteryless, Wireless sensor network, wireless sensors, switches, and controls. In March 2012, the EnOcean wireless standard was ratified as the international standard International Organization for Standardization, ISO/International Electrotechnical Commission, IEC 14543-3-10, which is optimized for wireless solutions with ultra-low power consumption and energy harvesting. The standard covers the OSI (Open Systems Interconnection) layers 1-3 which are the physical, data link and networking layers. EnOcean is offering its technology and l ...

Light Sensor
Photodetectors, also called photosensors, are devices that detect light or other forms of electromagnetic radiation and convert it into an electrical signal. They are essential in a wide range of applications, from digital imaging and optical communication to scientific research and industrial automation. Photodetectors can be classified by their mechanism of detection, such as the photoelectric effect, photochemical reactions, or thermal effects, or by performance metrics like spectral response. Common types include photodiodes, phototransistors, and photomultiplier tubes, each suited to specific uses. Solar cells, which convert light into electricity, are also a type of photodetector. This article explores the principles behind photodetectors, their various types, applications, and recent advancements in the field. History The development of photodetectors began with the discovery of the photoelectric effect by Heinrich Hertz in 1887, later explained by Albert Einstein i ...

Window Blind
A window blind is a type of window covering. There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats. Vertical blinds run along a track system which can tilt open and closed and move side-to-side. Window blinds can be manoeuvred with either a manual or remote control by rotating them from an open position, with slats spaced out, to a closed position where slats overlap and block out most of the light. There are also several types of window coverings, called shades, that use a single piece of soft material instead of slats. The term window blinds can also be used to describe window coverings more broadly. In this context window blinds include almost every type of window covering, whether it is a hard or soft material; i.e. shutters, rol ...

Light
Light, visible light, or visible radiation is electromagnetic radiation that can be visual perception, perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequency, frequencies of 750–420 terahertz (unit), terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively ''optical radiation''. In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity (physics), intensity, propagation direction, frequency or wavelength spectrum, and polarization (waves), polarization. Its speed of light, speed in vacuum, , is one of the fundamental physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building Automation
Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC, HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems. Some objectives of building automation are improved occupant comfort, efficient operation of building systems, reduction in energy consumption, reduced operating and maintaining costs and increased security. BAS functionality may keep a buildings climate within a specified range, provide light to rooms based on occupancy, monitor performance and device failures, and provide malfunction alarms to building maintenance staff. A BAS works to reduce building energy and maintenance costs compared to a non-controlled building. Most commercial, institutional, and industrial buildings built after 2000 include a BAS, whilst older buildings may be retrofitted with a new B ...

Osram
OSRAM Licht AG is a German company that makes electric lights, headquartered in Munich and Premstätten (Austria). OSRAM positions itself as a high-tech photonics company that is increasingly focusing on sensor technology, visualization and treatment by light. The company serves customers in the consumer, automotive, healthcare and industrial technology sectors. The operating company of OSRAM is OSRAM GmbH. Osram was founded in 1919 by the merger of the lighting businesses of Auergesellschaft, Siemens & Halske and AEG (German company), Allgemeine Elektrizitäts-Gesellschaft (AEG). Osram was a wholly owned subsidiary of Siemens AG from 1978 to 2013. On 5 July 2013, Osram was spun off from Siemens, and the listing of its stock began on Frankfurt Stock Exchange on 8 July 2013. Osram's business with conventional light sources was spun off in 2016 under the name LEDVANCE, Ledvance and sold to a Chinese consortium. After a bidding war with Bain Capital, Osram was taken over by Austria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zumtobel
The Zumtobel Group is an Austrian company specialising in lighting and headquartered in Dornbirn. Zumtobel engages in the development, production and sales of lighting, luminaires, lighting management and lighting components for indoor and outdoor applications. The company is a European market leader for professional lighting systems and the number two for lighting components in Europe. The group operates 10 production facilities on three continents as well as sales and partner companies in nearly 90 countries. Since 2007, the group has presented the Zumtobel Group Award (long name ') to architects and engineers every two years. The prize was worth 140,000 euros in 2012, 150,000 euros in 2017 and 120,000 euros in 2021. In the financial year from May 2017 to April 2018, the company recorded a loss of 46.7 million euros due to pricing pressure and currency effects and did not pay out a dividend for this period. Revenue declined by 8 percent and the share of LEDs in revenue increa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
