Halma Gas Detector Proves a Life Saver on National Geographic’s Mine Hunters

By on 23 August 2016

Mine Hunters, the National Geographic Channel series that follows a team on the trail of gemstones in some of the remotest regions on Earth, recently showed a glimpse of the lifesaving potential of personal gas detectors.

In the clip here, a Tetra 3 gas detector from Halma company Crowcon sounds the alarm as one of the gem hunters explores a ‘muddy pit mine’ in Madagascar.

Constantly monitoring gas levels around the wearer, the Tetra 3 quickly warns them about the dangerous lack of oxygen in the pit – and the mine hunters quickly pull their endangered colleague out of harm’s way.

Although this is quite an extreme example, lack of oxygen or dangerously high levels of other gases are real risks in many more mundane situations. Cooling towers, industrial vats and silos can all be very dangerous, with harmful gases pooling at the bottom – putting engineers, maintenance and cleaning workers in potentially grave danger.

Real-time, accurate gas monitoring is one of the best ways to protect their lives, and Crowcon products are trusted throughout the world to keep people in dangerous situations safe and healthy.

CenTrak adds Real Time Location Technology to our Medical Sector

By on 19 July 2016

CenTrak joined Halma in February, marking our entrance into a rapidly growing new market for the Medical sector: real time location systems (RTLS).

By cleverly combining technologies such as Wi-Fi, infrared and ultrasound, CenTrak makes systems that accurately sense and track where a person or object is within a hospital.

This data improves quality of care, response times and efficient use and allocation of resources – benefitting patients and healthcare professionals alike.

This is an intelligent and highly beneficial application of the growing ‘internet of things’ trend, and demand is already rapidly growing across the USA and rest of the world.

Sometimes it can be hard to see the value in the ‘big data’ culture – but when you see how much it can do to save lives and improve healthcare it really does start to look like the future.

Drawn to the light – how moths’ eyes help us make fibre optics more efficient

By on 7 July 2016

Moth eyes inspiring fibre optic technologyNature has inspired many scientific and technological advances over the years. Recently, scientists looked into how it is that moths’ compound eyes reflect almost no light – even when flying around a candle.

From this research a new anti-reflective technology has been developed, featuring randomly shaped and angled nanostructures. This randomised pattern actually improves on the already amazing light-absorbance properties of nocturnal insects’ eyes!

Halma company Fiberguide Industries will be using it to improve the efficiency of its fibre optic technology, especially for high-power applications such as medical and industrial lasers.

Fibre optics work by giving light a secure pathway to pass along, with almost no loss or interference. The principle is that whatever light is put in at one end comes out exactly the same, even if it has travelled long distances or through difficult environments. They work by ‘total internal reflection’ – the light bouncing along inside the fibre’s core.

Why then would you want anti-reflective coatings in fibre optics?

The problem comes at the ends of the fibres – where the light is put in, and where it comes out again. Any reflection at these points would be ‘losing’ light from the system.

So, by reducing the amount of reflection at the ends we can make the signal clearer, stronger, and closer to 100% efficient.

Plus, with no light leaking out, there won’t be any moths gathering around either.

Visiometrics adds unique diagnostic technology to our Medical Sector

By on 17 June 2016

Last December we acquired a very interesting business, Visiometrics, S.L., which has developed unique technology for measuring people’s eyesight objectively.

Their instruments give ophthalmologists a very precise measurement of the quality of vision of a patient’s eyes – very important in the early diagnosis of eye disorders such as cataracts.

We believe that this novel technology has high growth potential and could become a standard of care in ophthalmic diagnosis where our Medical Sector already has a strong global presence.

To learn more about Visiometrics and its unique products, watch this video featuring CEO Jan Bonel:

Fire protection for people – and giant pandas – at Kuala Lumpur Zoo

Preventing baby blindness with innovative telemedicine technology

Dr. Louise Allen examines baby's eye with Keeler ophthalmoscope
Baby eye examination

One of the unfortunate challenges facing early, low birthweight babies is a high risk of suffering from an eyesight-threatening condition: retinopathy of prematurity (ROP). Untreated, it can lead to blindness, and the key in successfully treating ROP is quick detection and diagnosis.

Louise Allen, Consultant Paediatric Ophthalmologist for Addenbrooke’s Hospital in Cambridge, is fighting back with the help of digital ophthalmoscopes from Halma company Keeler and the support of the Addenbrooke’s Charitable Trust (ACT).

In Louise’s words: “Addenbrooke‘s is the established treatment centre for ROP in the Eastern region neonatal network.

“That used to mean that any at-risk babies in the East of England were immediately transferred to us – sometimes over long distances – to Addenbrooke’s so we could examine them in person.

“This was obviously stressful and disruptive for the baby and its parents, and it created a significant knock-on effect in the ward, requiring other babies to be moved to other units in the region to free up cot space for the transfer.

“It made sense to adopt a new approach.”

Keeler Vantage Digital indirect ophthalmoscopes are now being provided by the ACT to other hospitals throughout the region. With these, staff at the babies’ local hospitals can take a high-quality digital image of the insides of their eyes and send it instantly over to a specialist like Louise for screening.

With innovative use of technology like this, patients can receive better, faster care and hospitals can avoid unnecessary disruption – and the critical expertise of specialists like Dr. Allen can reach those who need it in the blink of an eye.

Introducing Firetrace, a recent addition to our Infrastructure Safety Sector

By on 21 December 2015

Earlier this year we acquired Firetrace USA, LLC for roughly £73m. Joining the Infrastructure Safety Sector, Firetrace significantly expands the scope of our offering in the fire protection market.

Until recently we had a strong focus on the detection of fire with smoke, heat and flame sensors. Then, two years ago, Halma acquired Advanced Electronics, bringing control panels and systems into our portfolio as well. These products protect people, property and assets throughout public buildings, commercial premises and residences.

Firetrace products are a little bit different: they operate as combined detection and suppression systems for specific, enclosed environments to protect high value or safety-critical assets. Server rooms, electrical cabinets, wind turbines and even law enforcement vehicle fuel tanks are all protected by Firetrace – complementing our existing markets and opening up new ones to us as well.
