Anatoly Glivinsky Overview of the latest generation of CREE LEDs
Lighting systems accompany us everywhere: at home, on the way to work, at work. We are so used to them that we do not even notice that this light was not created by nature, but made by human hands. But global energy problems are pushing us not to stop at what has already been achieved, but to conduct new searches for sources of artificial lighting. The world energy saving program has done a lot for the process of such a search. Within the framework of this article, the history of the creation of artificial light will be presented, the advantages of LED lighting will be shown. We will also tell you about the leader in LED products and introduce you to the latest innovations in the field of high-power LED components.

Andreas Paul, translation: Sergey Sheiko Solid State Lighting Design
This article is devoted to describing the difficulties that a developer may face when designing LED-based lighting fixtures. The issue of using discrete 1-watt LEDs for thermal calculation is directly raised, in which heat is efficiently dissipated from high-power LEDs onto optical lenses that are currently available to the buyer in the electronic component market. The issues of efficient and compact use of LEDs (small drivers, parallel or series connection) are also considered.

Aramais Andreasyan Visual information system for passengers of the airport "Boryspil"
The information technology service of the Boryspil International Airport, together with the Granato illegal armed group, has put into operation a system of visual informing of passengers on the airport apron buses that deliver passengers from the terminal to the aircraft.
The information on the scoreboard comes from the automated control system of technological processes of the airport via a wireless Wi-Fi network, providing information to passengers in a simple and understandable form completely excludes the possibility of a passenger boarding a bus on a wrong flight.

Alexander Yorkin The displays we choose
Displays are an integral part of our information environment. When purchasing a computer or TV, we are always faced with the problems of choosing technology, display size and format, display maintenance, the problem of “dead” pixels, etc. This overview examines the practical aspects of choosing and using displays for work and play.

Artem Kozlov Microcontrollers with dynamic transfer of pin functions
Along with the increase in the number of functions in the controller software, the "flexibility" of operation increases and the cost of the microcontroller system decreases. The next step in the development of microcontrollers is to increase the "flexibility" of their basic design.

Roger Chan, Alan Hastings Multiswap Mode: A New Approach to Current Limiting for Power Redundant Systems
The new TPS2359 controller provides all the power management features you need to hot-swap two AdvancedMC ™ (AMC) modules. The controller's current limiting circuits help meet the stringent requirements of the AMC standard. This is especially important when applications are using backup power. A unique feature called Multiswap provides a stable current regardless of the number of power supplies connected to the load.

Norbert Hauser Main trends in the market of embedded computer products in 2009
Changes in the market for embedded computer products will go this year in three main directions. First, the emergence of new miniature processors with a high degree of integration will lead to an increase in the popularity of smaller form factors, and more complex multiprocessor solutions will be implemented in larger constructs. Secondly, the difficult economic situation will serve as an incentive for mass migration towards outsourcing. Third, when choosing suppliers of embedded products, more and more attention will be paid to their financial situation.

Markus Hermwil, Andrey Kolpakov SKYPER 52 is SEMIKRON's first ultra-high power digital IGBT driver
For the operation of any converter created with the use of IGBT modules, a device is required that transfers control signals from the controller to the gates of the power switches. With an increase in power, this task becomes more and more difficult, for its solution it is necessary to increase the load capacity of the drivers, to increase their noise immunity and resistance to induced voltage fronts. In addition, a modern control device must perform a whole range of protective and service functions.
The main goal of the development of the all-digital SKYPER 52 driver was to provide high quality transmission of isolated control signals in medium to high power systems. This article describes the main characteristics of the new control device and discusses the advantages of digital data transmission.
