Windows 7 Professional and Ultimate for Embedded Systems are embedded versions of the Classic Windows 7 desktop OS, and are available for fixed-function or dedicated systems.
They are designed for devices with a strict need for Microsoft Windows 7 application compatibility and where reduced footprint is not a primary design requirement.
Unlike Microsoft Windows XP Embedded, Windows 7 with Embedded Restrictions is not a componentized version of the Windows OS and an OEM Preinstallation Kit (OPK) is needed to produce the OS image. Therefore, the OS image size is not as customizable.
Following features are only available in Windows 7 Ultimate: MUI Support, BitLocker, BitLocker to Go, VHD Boot, Direct Access, AppLocker, BrancheCache, VDI Remote Desktop.
A resistive touch screen panel comprises several layers, the most important of which are two thin, transparent electrically-resistive layers separated by a thin space. These layers face each other, with a thin gap between. The top screen (the screen that is touched) has a coating on the underside surface of the screen. Just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is passed through one layer, and sensed at the other. When an object, such as a fingertip or stylus tip, presses down on the outer surface, the two layers touch to become connected at that point: The panel then behaves as a pair of voltage dividers, one axis at a time. By rapidly switching between each layer, the position of a pressure on the screen can be read.
Resistive touch is used in restaurants, factories and hospitals due to its high resistance to liquids and contaminants. A major benefit of resistive touch technology is its low cost. Disadvantages include the need to press down and a risk of damage by sharp objects. Resistive touch screens also suffer from poorer contrast, due to having additional reflections from the extra layer of material placed over the screen.
In many ennvironments electronical devices must stand rough conditions and work for their indetnded period of time nevertheless they are set out to dirt, dust and humidity. IP protection classes define, how and where they can be used without getting a safety risk. Especialy in medical areas the safety is very important for the device and all above for the patients.
The following table shows the different IP protection classes:
|IP||Characteristic 1 for protection against contact||IP||Characteristic 2 for waterproofing|
|0||No special protection||0||No waterproofing|
|1||Protection from solid objects greater than 50mm in diameter||1||Protection from dripping water|
|2||Protection from object not greater than 12mm in diamete||2||Protection from vertically dripping water (tilted up to 15°)|
|3||Protection from object not greater than 2,5mm in diameter||3||Protection from sprayed water (tilted up to 60°)|
|4||Protection from object not greater than 1mm in diameter||4||Protection from splashed water|
|5||Complete protectionm against contact, Protection against dust deposit||5||Protection from water projected from a nozzle|
|6||Complete protectionm against contact, Protection from infiltration of dust||6||Protection against heavy seas, or powerful jets of water.|
|7||7||Protection against immersion|
|8||8||Protection against complete, continuous submersion in water.|
|9||9||Protection against the ingress of water form all directions even under greatly high pressure on the housing. (High-pressure/steam cleaner, 80-100 bar)|
Industrial CPU cards are designed to survive the harsh environment, where extremes of temperature, vibration and electrical noise could easily damage 'normal' system components. Commercial motherboards are not designed for such environments.
Motherboards come cheap, but you (don't) get what you (don't) pay for:
As mentioned previously, industrial CPU cards minimize system downtime (e.g. passive backplane cards all comply to standard mounting specs), and allow an easy upgrade path as newer technology becomes available.
Think of an IPC (Industrial PC) in terms of your desktop computer: many of its technical characteristics and features are basically the same: processor & RAM type. storage media, interface ports, performance, etc. However, an Industrial PC is a ruggedized system, fit for use on the shopfloor.
First of all, industrial computers are especially designed to withstand harsh environments (extremes of temperature, dust, humidity, vibration, power surges) that commercial PCs are not designed for.
Before choosing a ‘PC’ for your application, you should always take into account the following factors:
Mobile computing devices, namely tablet PCs and industrial PDAs, are becoming increasingly popular for out-field use. Their versatility makes them useful in public safety and field service applications. However, popular consumer tablets or handhelds are not designed to meet outdoor use, especially where the environment is tough. They are not designed to work in the rain, or extreme hot or cold temperatures, or in areas where dust and dirt could interfere with the device. For these environments, tougher devices are required – those that meet the “rugged” standard.
So, what defines “rugged”? From the user’s perspective, rugged refers to the device’s ability to operate in the work environment that in is exposed to. However, different users work in different environments. Hence, rugged means something slightly different from one user to the other. For example, a tablet PC used in a warehouse will be more likely exposed to dust and drops, but will less likely be used in extreme temperatures. To meet the needs of all possible users, the industry has agreed upon a general a set of standards to test for a device’s ruggedness. There standards include tests for: extreme operating and storage temperatures, Ingress Protection (IP Grade) as well as drop survival.
EPIC is to define a new industry open standard for small form factor embedded computer boards, call Embedded Platform for Industrial Computing or EPIC. The EPIC single board computer has multiple I/O expansion options. Its size is midway between the industry standard PC/104 module and EBX board. The boards in EPIC form factor support advanced processors plus complex I/O functions for applications involving data acquisition, video processing, telecommunications, networking, motion control plus the associated field wiring termination, I/O circuit protection, etc. The initial specifications define PC/104 expansions; however, future updates will embrace PCI Express and/or other expansion features. The EPIC standard provides a platform on which to build the next generation feature-rich embedded system for industrial, medical, military, transportation, and commercial applications.
Industry is traditionally slow to adopt any new Microsoft Operating System (OS). Many industrial Windows users will have no need of the many new features on offer and will be highly cautious at potential bugs or security flaws that could be lurking within. The majority of industrial products will have life expectancies of over 5 years and would have been developed around a specific Operating System. In short, it is rarely worth considering switching to a new Operating System unless you are developing a new product.
At first glance, the appearance of Windows 7 is similar to Windows Vista. However, when you start using it you will be pleasantly surprised at how fluid and quickly it runs. Interestingly, if you compare the minimum hardware requirements between Windows Vista and 7 they are almost identical. However, Windows 7 was developed from the ground up with a simple aim to be much faster than Windows Vista. This is a significant change of thinking from Microsoft, especially when considering the upgrades which were necessary when moving between Windows 98, XP and Vista. The minimum hard drive capacity for Windows 7 of 16GB is still significantly larger than Windows XP which was a mere 1.5GB. Those users wanting a trimmed down version can choose Windows Embedded Standard “Quebec”, which is based on Windows 7 code.
Similar to Windows XP and Vista, Windows 7 follows suit with the number of supported processors. The Professional, Ultimate and Enterprise editions all support two physical processors regardless of the number of cores within each processor. However, unlike Windows Vista and XP Windows 7 supports up to 256 cores and scales in a linear fashion.
Excluding Windows 7 Starter, each of the editions will ship with 32-bit and 64-bit variants. The 64-bit versions will also support 32-bit applications. Although 64-bit computing has some significant benefits, if the applications or hardware does not fully support this , you should stay with 32-bit to avoid unexpected errors.
To make use of this feature, you need to download and install both Microsoft Windows Virtual PC and Windows XP Mode.
The technicalities surrounding XP mode are a little vague and first impressions could give false hope of providing a fully compatible Windows XP machine. The XP Mode is designed to support legacy software applications only and cannot see or interact with most hardware. If any hardware was plugged into the machine such as a PCI Data Acquisition card, the virtual XP Mode would be oblivious to it.
This feature may be of use if you have a standalone legacy application which you are unable to run within Windows 7 which would otherwise have to be run on a separate PC.
Windows XP and Vista treat an SSD as a mechanical hard drive. To support the growing popularity of SSD being used within systems, Microsoft has added a number of features into Windows 7 to improve the life expectancy and performance of Solid State Disks.
