In a paper published in Scientific Reports by Nature, scientists from Surrey joined forces with Johns Hopkins University in Baltimore and the University of California to develop a material that has high stiffness and damping. The team achieved this near impossible combination in a material by using 3D woven technical textile composite sheets, with selected unbonded fibres – allowing the inside of the material to move and absorb vibrations, while the surrounding material remains rigid. Researchers believe their new material could usher in a new wave of trains, cars, and aircrafts, allowing customers to experience little to no vibration during their travels. Dr Stefan Szyniszewski, lead author of the study and Assistant Professor of Materials and Structures at the University of Surrey, said: “The idea of a composite the resolves the paradox of stiffness and damping was thought to be impossible – yet here we are. This is an exciting development that could send shock waves through the car, train and aerospace manufacturing industries. This is a material that could make the vehicles of the near future more comfortable than ever before.” Fig. 1: (a) 3D woven (3DW) lattice material is composed of Z- (green), warp (red) and fill (blue) wires; (b) Yellow color indicates the brazing locations (at the top and bottom).

BT chooses Perle Terminal Servers for remote access and management of LDU’s

bt-logo

iolan-sts8dc_lgThe “residential phoneline” section of BT was operating a mixed X.25 and Ethernet environment. The goal for BT was to get rid of the X.25 WAN and have a direct IP connection to Loop Diagnostic Units (LDU). This would enable them to communicate with the exchanges at a much higher speed, allowing them to service their customers more efficiently and quickly. While moving to an IP Network, it was important not to replace all of the existing infrastructure that was not at the end of its lifecycle.

The Scenario:

A residential customer reports that their phone line appears not to be working. At BT’s headquarters a test of the line, via the exchange, is initiated. To test a phone line engineers connect to a LDU (Loop Diagnostic Unit) at the exchange that checks the line. This first check indicates whether the line is clear and operating or whether further investigation is required and an Engineer needs to be dispatched.

This initial check was previously done across the X.25 Network. A user on a remote network opened an application, entered an IP address and a port number, and sent a command to an LDU across the LAN and then through X.25 pads to a serial connection on the LDU. The LDU communicates via a serial link to request the specific line to test. The HQ gives the LDU the line or a batch of lines, the LDU tests and feeds back to the user on the LAN.

BT wanted a direct IP connection to the LDU, replacing the X.25, which would enable them to communicate with the exchanges at a much higher speed, allowing them to service their customers more efficiently and quickly. There was no requirement to replace the LDU, as this had not reached the end of its lifecycle. However there was a need to be able to access it over Ethernet, securely and remotely.

Most exchange sites have one LDU. Some have more than one requiring a higher number of serial ports. Each LDU has 4 serial ports, consisting of an admin port, a port to the exchange, an Xserver port, and a serial port for Ethernet Connectivity.

Working closely with Perle Systems, a suitable product from the IOLAN Terminal Server range was quickly identified. The selection process focused on key requirements including:

Redundancy – a backup feature to support the LDU’s in the event of loss of power
Security – meeting BT’s “Safe to Connect” Standard
Support – local UK based support.

IOLAN STS 8 DC Terminal Servers were installed at the Exchange sites, and connected to the LDU’s.

IOLAN Terminal Servers from Perle Systems helped BT keep their LDU’s while accessing them over IP remotely.

o meet the redundant power requirement, Perle IOLAN STS8 DC Terminal Servers were connected to 2 fused 50v feeds generated by a dedicated Wind Farm with a centralised earth going into the primary and secondary DC power inputs. The dual feed DC IOLAN Terminal Servers from Perle operate so that in the event the primary power source is depleted, the IOLAN pulls power from the secondary source and is able to switch back and forth as necessary, thereby ensuring continuous operation.

In addition, after extensive testing,  Perle IOLAN STS Terminal Servers underwent and passed BT’s “Safe to Connect” requirements, which is a series of requirements more stringent than normal Telco testing would require. The whole of the IOLAN STS Terminal Server range was tested and met the various standards needed.

IOLAN STS DC Rack Terminal Server is available with 4, 8 or 16 RS232 RJ45 Ports, 10/100/1000 Ethernet, Dual Feed 48v DC power ( 36 to 72v DC range ) and an advanced security feature set.

IoT and patient-generated data are unlocking health care value

Max Burkhalter

The Internet of Things (IoT) driven health care space focuses on wearables, telehealth, and servicing patient with chronic conditions as well as fitness, nutrition, and weight management concerns.

IoT-and-patientgenerated-data-are-unlocking-health-care-value_728_40178584_0_14142561_500According to a 2016 report from Grand View Research, Inc, the global connected health and wellness devices market was valued at $123.2 billion in 2015 but is expected to reach $612 billion by 2024. An increased reliance on tele-health as well as a rising number of individuals diagnosed with chronic illness is creating demand for disease management and continuous patient monitoring tools. IoT connected health devices with access to electronic patient health records can provide comprehensive health information and assist in creating personalized treatments.

IoT Driven Data Sharing
According to Deloitte, health care providers struggle with the fact that interactions with their most vulnerable patients are often sporadic, providing them with low insight into their patients’ daily decisions and activities. Compliance with treatment plans can be compromised and important information missed, leaving the medical provider blind to important health information and frustrated with bad patient outcomes.

If the flow of information and feedback between patients, providers, and caregivers is enabled with IoT connected devices, everyone is able to get on the same page for patient care. Decisions are now made with all pertinent information in hand and patient outcomes improve exponentially. Fortunately, new technology can make that possible, with IoT wearable medical devices that track internal patient data around the clock and make recording external data easy.

x_0_0_0_14069020_800
The IoT can help unlock patient data.

Patient-Generated Data
The key is patient-generated data (PGD), which is commonly defined within the industry as “health-related data created, recorded, gathered, or inferred by or from patients or their designees to help address a health concern.” Patient reported outcomes, medical-device data, and wearables data can all be part of individualized PGD, and supplemented by more generalized consumer-generated data in a health care setting.

Mass adoption of IoT devices and wearable medical devices, including sensors and mobile communication devices, is an industry growth driver as consumer preferences towards a more health-conscious lifestyle. The advantages of continuous monitoring for many chronic conditions encourages patient compliance and allows daily logging to become more reliable, delivering more accurate PGD for better outcomes.

The Role of IoT in Health Care Value
The latest versions of digital PGD is being increasingly generated by IoT technologies. Two key areas benefit from IoT-connected data collection medical devices, including:

Short-Term Care Planning
A short-term care period can be utilized to generate massive amounts of event related data and create a customized care plan that encourages patient compliance and provides support in the way of feedback, reminders, and continual monitoring.

Long-Term Chronic Disease Management and Home Care
Known health issues such as high blood pressure or diabetes can be monitored narrowly with continuous data streams tracking any potentially concerning deviations from normal parameters and providing alerts both to patient and caregiver or doctor if required.

The use of IoT connected devices to record and share PGD presents substantial opportunities for health outcome improvements, patient engagement, and cost savings. Deploying wearable medical devices allows doctors to partner with caregivers to deliver treatment tailored to individual patients, creating a patient-centered environment that promotes compliance and contentment.

Complex patient monitoring devices can be interfaced to a single network connection and managed across the internet. Perle Serial Console Servers provide administrators with access from anywhere, allowing remote management to reduce cost while maintaining network security and patient privacy.

Scientists create battery that refuels electric cars in seconds

Liquid Battery

A team at the University of Glasgow has created a prototype system that could revolutionise travel.

The technology uses a metal oxide – described by researchers as an “exotic rust” – that can be charged with electricity when added to water.

Drivers would use filling stations to refuel their electric cars, driving away instantly once a battery is full.

Prof Lee Cronin, who is part of the research team, said the liquid battery could hold the key to making electric cars a viable option to fossil-fuelled vehicles.

‘Cultural inertia’

Prof Cronin told BBC Radio’s Good Morning Scotland programme: “This will overcome a big kind of cultural inertia – you can get instant refuel in the same way, with no change to your behaviour now.

“Because it’s a liquid it would just work as normal using the same infrastructure.

“It will certainly be a game changer if we can make sure that the prototype scales as we expect.”

_102961779_hi046658828

Drivers would remove the spent “rust” liquid using a withdrawal nozzle at the pump.

They would then use a second nozzle to refill the battery with fresh liquid from the pump.

The Glasgow team said the liquid would provide the same range of miles as conventional fossil fuel.

And Prof Cronin said his liquid battery did not age in the same way as current electric systems.

‘Unstoppable barrier’

He also said their capacity – the amount of energy they can carry – was higher.

The team said the process of making the liquid was not too difficult but scaling up production was the next challenge.

The technology could also be used to keep power domestic energy supplies.

A small prototype is being upscaled at present – and everything seems to be going well, according to researchers.

Prof Cronin said: “If you are going to shift to electric cars, recharge time seems to be an almost unstoppable barrier because you are going to have to plan – even with a super-charger – a half-hour to 45-minute wait.

“And then there’s the anxiety of whether you have got enough charging stations.

“I can see a situation where you would have petrol and liquid battery co-existing for a while.”

The research is funded by the University of Glasgow, the European Research Council and the Engineering and Physical Sciences Research Council.
