The role of women in engineering
According to the Women’s Engineering Society (WES), less than ten per cent of engineering professionals in the United Kingdom are women, the lowest figure in Europe. Latvia, Bulgaria and Cyprus are leading the way, with female engineers making up almost 30 per cent. Here, Helen Marston, engineer at specialist resistor manufacturer, Cressall, discusses the role of women in engineering throughout history.
Humans need a digital twin for zero unplanned downtime
Mark Homer, Vice President Global Customer Transformation for ServiceMax, discusses the concept of a digital twin.
How electrical interference can cause pacemaker issues
During the French Revolution, beheading was the preferred method of execution. The guillotine was used for thousands of executions, meaning there was no shortage of experimental material for biologist Marie Francois Bichat. Bichat tested the electrical stimulation of hearts, which was instrumental in the development of the modern day pacemaker. Nowadays, pacemakers are commonly used to maintain a regular heart rate. Here, Keith Armstrong, worldwide electromagnetic compatibility (EMC) expert at EMC Standards, looks at how electrical interference can cause pacemaker issues.
Why it can pay to choose custom rather than standard sensors
Sam Drury, Sales & Marketing Director at Impress Sensors & Systems Ltd, explains why some engineers prefer custom pressure sensors over standard, off-the-shelf versions.
Load holding valves made simple
Load holding valves, also known as counterbalance valves, are a small but important part of any mobile machine. Though simple in design, their application can often frustrate even the most skilled and experienced engineers. Having a basic understanding of load holding valve operation and how to apply them can allow engineers to improve the stability and reduce cost in mobile equipment. Todd McIntyre of Eaton Hydraulics discusses load holding valves.
Optimas Solutions supplies global pedigree with a local touch
The phrase ‘global supplier’ spurs thoughts of shipping containers travelling the world and large multinational corporations employing highly complex logistical operations; all controlled from a centralised super-hub. However, this is not an entirely accurate reflection of what it takes to be a successful global supply partner. Traditional global frameworks can be slow to respond to local concerns, while moving products around the world can also be costly and time consuming. Therefore, to effectively service demands with speed at a local level, a global approach must be blended with a local ethos – a scalability of service.
WDS ball joints bring flexibility to wide range of systems
Most people use ball and socket joints every day, in the form of their hips. They allow people to move in many ways - from gentle strolls to rigorous exercise. In engineering terms, axial ball or ball and socket joints rotate smoothly in all directions, so can absorb considerable amounts of misalignment of shafts and structural elements. As such they are invaluable in a wide variety of machines and engineered systems.
Miss M8ty - enabling Ethernet from the sensor to the cloud
Matthias Fritsche and Jonas Diekmann of Harting introduce Harting's new heroine, Miss M8ty, and explain how she and the company's new M8 D-coded connector will enable machine builders to provide Ethernet connectivity from field-level devices through to top-level monitoring and control systems, including the cloud.
