Enabling robust data communications within a high voltage BMS

The primary purpose of the battery management system (BMS) is achieving reliability, performance and longevity of battery packs. As part of this, the battery management electronics measures each cell voltage and transmits this information to a central processor. For high voltage battery strings – such as is typical for automotive drivetrains –a modular distributed pack is an attractive choice. Battery modules can serve as the basic building block for multiple pack designs. Modules also allow for optimal weight distribution and maximum use of available space. The biggest challenge is the datalink required to operate the pack as a single unit.

New technologies widen touchscreen opportunities

A quiet revolution is taking place in the projected capacitive touchscreen market. Rapid industry developments are delivering touchscreens which are thinner, higher performance, more reliable and lower cost. The impetus behind many of these developments is the fact that indium tin oxide (ITO), the long standing conductive material of choice for phone and tablet touchscreens, has limitations and consequently is being superseded by alternative materials. ITO has never been widely used in large format AV and kiosk applications, but some of the technologies that are being developed to replace it could.

As the IoT unfolds, classical EDA design flows will need to change

For the past 20 years, the rhetoric of integrated circuit design has been one of increasing exclusivity, despite the falling cost of transistors with each jump in process node. The rise in mask and software tool costs over those same generations has forced many would-be chipmakers to settle for off the shelf microcontrollers and programmable logic.

Data centre interconnect drives optical module advances

The huge growth in demand for video, cloud services and social networking is changing almost everything about the way the networks are built and used, not least the interconnect technologies within data centres and the ‘top of rack’ network switches that shift packets between the optical internet boxes – or Data Centre Interconnect (DCI) – and the servers that store and process the data.

Intel’s Programmable Systems Group takes its first step towards an FPGA based system in package portfolio

Speaking in 2012, Danny Biran – then Altera’s senior VP for corporate strategy – said he saw a time when the company would be offering ‘standard products’ – devices featuring an FPGA, with different dice integrated in the package. “It’s also possible these devices may integrate customer specific circuits if the business case is good enough,” he noted.

Irish company pioneers the development of 94GHz RF circuits for a range of applications

It wasn’t too long ago that GHz frequencies were regarded as exotic; few applications took advantage of that part of the spectrum as technology was not only difficult, but also expensive. That meant that military dominated the few applications there were. The Brimstone missile is believed to use 94GHz technology for targeting purposes, rather than the lasers used in previous missiles.

The Brexit debate: should we get out or ‘remain, reform and revitalise’

Could the UK pulling out of the European Union pose as big a threat to the global economy as a ‘hard landing’ in China? That was the claim made recently by the Organisation for Economic Co-operation and Development’s (OECD) chief economist Catherine Mann. According to Mann, a vote to leave the EU will not only impact the UK, but would also have a significant impact on the global economy.

RF tests are the basis for V2X

Wireless technologies are being used to connect vehicles, but in order to ensure that messages are received accurately, developers need to adhere to minimum standards.

The benefits of using non-isolated DC/DC converters

The DC power requirement for electronic industrial equipment often consists of a 24V high power output and a number of lower power, lower voltages. Traditionally these requirements have been achieved by a number of power architectures, depending upon the amount of system power required.

Power supply standby voltage and off-load power draw

The use of a Standby Voltage on computer power supplies became widespread when the ATX specification was published in 1995. It enables a computer to be put into a low power consumption mode without fully powering down the processor, allowing a quick response when activated again. This was achieved by using a remote on/off signal to turn off the outputs, but still supplying a small amount of power to the processor from an independent voltage. This ‘Standby Voltage’ is always present even if the main outputs are inhibited using the remote on/off.

Technology developers could ease the burden on the NHS

If you think telemedicine and telehealth are relatively new concepts, think again. Amazingly, the idea was first floated in the US in 1925 by Hugo Gernsback. His concept – the teledactyl – combined wireless communications, haptics and a form of viewscreen. It would, he contended, allow doctors to examine their patients and to use instruments remotely.
