Fanless console server, with multiple serial ports up to 16 serial and 10 Ethernet/LAN ports are Intel x86 based ranged from ATOM up to Pentium. They are also known as console access server, console management server, serial concentrator, or serial console server. Typical of console server applications are telecommunication, healthcare/medical, building automation, electric utility, transportation,factory automation, data center, POS and SCADA.

Power plant efficiency in search
In power plant, the actuator and valve create a single unit — the control valve. Actuators perform different motion sequences, including linear, pivoting and rotating motions, and they are powered by pneumatic, hydraulic or electrical energy. Actuators receive a control signal from automation systems and single board computer. The single board computer is converted into a motion so that the control element of the actuating element assumes a corresponding position. With control valves, this is a stroke motion. With flaps, ball cocks or rotary plug valves, this is a pivoting motion.
Power plants have traditionally used pneumatic actuators to drive the many control valves throughout their facilities. However, major improvements in embedded systems control-valve actuator technology are helping power providers achieve their most important objectives at a lower cost.
The new electric actuators can hold up to the demands of continuous movement.

Qseven Computer-On-Module (COM) challenges
Increasing numbers of patients, shrinking numbers of embedded computer physicians, and rising costs are pushing the medical field further into the age of telehealth. Unlike traditional clinical platforms, however, telemedicine demands portability, flexibility, and long lifecycle support from Small Form Factor (SFF) technologies. Targeted at low-power mobile applications, Revision 2.0 of the Qseven Computer-On-Module (COM) specification added support for ARM CPUs and defined a "micro" form factor, making it good Commercial Off-The-Shelf (COTS) medicine for next-generation telehealth systems.
Go to doctor’s office. Wait. See embedded computer Primary Care Physician. Get tested. Wait. Get referred to specialist. Get retested. Wait. Get referred to another specialist. Wait. See how much insurance covers. Pay accordingly.

Satisfying rugged memory requirements
While demands for ruggedized embedded devices continue to rise, memory module suppliers continue to make technology
advancements and associated manufacturing enhancements that meet the needs of
OEMs. DDR3 SODIMM, DDR3L, and lower-profile DDR3L are all examples of new
technologies that help satisfy rugged memory requirements. These advancements
solve many design challenges, including low power, enhanced thermal
dissipation, and extended-temperature tolerance while delivering the
performance needed for today’s complex embedded systems.

Embedded developers challenge to fasten system operating
Developers
can often find answers to their questions through the Internet, but no one is
on the hook to research and respond to a embedded computer specific question. Open source
products are generalized in order to fit the widest array of users and can
force designers to modify the hardware configuration, resulting in higher
recurring cost for the embedded device. Cost
is obviously a major deciding factor when selecting an embedded operating system. Since there is essentially no cost of goods with software, vendors can
adjust their pricing model to generate revenue from various sources. Vendors
can charge for an initial license fee, development seats per engineer,
development tools, per-unit royalties, continuing support, or major upgrades.
To fairly compare prices, the overall cost of ownership must be computed for each
OS being considered.
Memory needs for in-vehicle system
Automotive electronics are memory hungry.
Therefore, the explosive growth of in-vehicle infotainment systems in modern cars has a
significant impact on the market demand for semiconductor memories. For 2012,
the average memory content of a car was estimated to be around US$12.8, ranging
from US$2.0 for low-end models to more than US$100 for fully equipped luxury
vehicles. As a result, the total available market value for in-vehicle memories in automotive applications is expected to reach a Compounded Annual
Growth Rate (CAGR) of more than 9 percent from 2011 to 2015, well above the
overall CAGR for the total memory semiconductor market, which is less than 7
percent.

Think you know embedded system? Rethink again...
“Many people initially think a cloud is inherently insecure as it is a single point of failure –the cloud goes and all your data goes with it,” says Todd Moore, Vice President of Product Management at SafeNet (www.safenet.com). “However, embedded computer build in redundancy so when they write data to a cloud, they also write it to a disk at the same time. The virtual environment is encrypted and is also stored on a disk.”
“Securing the cloud is simple, as it is about providing assurance,” says Will Keegan, Technical Director, Software Security at LynuxWorks (www.lynuxworks.com). “Users need to feel comfortable that when they log on remotely, every transaction they make will be secure. The complexities of public ISP embedded computer systems are too high to assure that data loss or leakages cannot occur. In a public cloud you have to assume all users are adversaries, and we rely on the ISP to protect other customers from stealing my data.”

Embedded product development and networking
Testing and traceability play a vital role
in embedded product development. Traceability rendered via Application
Life-cycle Management (ALM) software enables the team to automatically generate
networking cases that link back to requirements, and report defects that link
back to test cases. By knowing that defects are addressed and test cases run
successfully, the team can have an immediate networking and accurate accounting
of the state of product requirements.
Fifteen or 20 years ago, many embedded
systems consisted of an 8-bit processor with a few KB of memory and perhaps a
couple hundred lines of networking. Today, the explosion of embedded systems in
automobiles, ATMs, cell phones, and other devices has dramatically changed that
dynamic. It’s not uncommon to see multiple 32- and 64-bit multicore processors
on an Ethernet network, running multiple applications totaling hundreds of
thousands of lines of code in these systems.
