While the overall R&D process for a medical device takes years, most of this timeline is absorbed by tooling and component lead times, market feedback, life testing and regulatory approval. Design engineers often have very tight windows to complete their next deliverable before the deadline. To meet early-stage deadlines, it is a common and accepted practice to design th...
Due to the presence of electronic components and materials susceptible to corrosion, moisture is often a cause of premature failure, particularly for electric motors. Designers need to consider how to mitigate the effects of moisture—from saline, steam sterilization, or other contaminant sources—by preventing ingress where possible, selecting robust components, and isola...
To keep the cost of procedures down, the most sophisticated tools must be used in high volume which requires steam sterilization (autoclaving) between patients. High volume surgery centers (often referred to as Tier-I) can both afford the upfront cost of these premium tools and perform enough surgeries to bring the cost per patient to an affordable level. However, this e...
The conveyor system is the mechanism that minimizes manpower in distribution and transfer. Conveyor belts are the most important transportation vehicles used in the horizontal or inclined transportation of solid materials over long distances. Operating using two rotating pulleys to move the material, these conveyor belt systems can consist of an infinite number of hooks...
Electrical hazards can cause electrification (or electrocution) as well as burns with serious injuries or even amputations. Working on electrical installations exposes you to the risk of an electric arc. The thermal impact of an arc depends not only on the voltage level (LV/HV) but also on the incident electrical energy (cal/cm²). Effective and appropriate personal prote...
The presence of uncontrolled quantities of air in water systems can seriously affect their performance, causing inefficient filling and draining procedures and flow reduction, while increasing energy costs. It also disrupts the operation of some of the system’s components. On the other hand, air is essential in dealing with vacuum conditions and pressure surges. Effecti...
From society to politics to industry – everyone acknowledges that a functioning circular economy is necessary to meet climate goals. Everyone also agrees that the use of recyclates must be significantly increased. But there are a number of obstacles and problems along the way. For example, not enough recyclates are available in sufficient quantity and suitable quality....
Water quality monitoring has evolved significantly over the past decade. Today’s industrial manufacturers have access to technologies that are capable of monitoring various wastewater quality parameters and contaminants of concern in a simple and effective manner. A continuous stream of water quality information to a plant’s control system can provide significant value.
Gull Lake in central Alberta was challenged by falling water levels from the 1920s to the 1970s. In 1976, Alberta Environment (AEP) implemented a stabilization system to pump water into the lake from the Blindman River via a pump house, 30-inch pipeline and canal. The pump house has three 480 volt pumps with a combined output of 53m3/minute (14,000usgpm) at pressures of...
For Fuyu, the previously produced drawings and the standardized modules with related materials can be regarded as modular products. Conversely, new designs with relatively large design changes based on existing modules can be regarded as "non-standard customization". After the non-standard technology is mature and finalized, it will be transformed into standard equipment...
In August of 1933, R.O. Monroe and L.D. Goff, in conjunction with a local mill, designed and built the first rotary joint. It was a device that eliminated the problems associated with stuffing boxes and packing glands and allowed the water or steam to be introduced in a much more economical method
Depureco created a definitive document that explains what Atex is, in simple words and clear patterns.
Check valves are used in many applications to control the flow of gases or liquids using varying mechanisms. Vacuum systems and small-bore, low-pressure systems often incorporate diaphragm check valves to prevent reverse flow and the risks associated with it. This blog post will discuss the types of diaphragm check valves and how they work. WHAT ARE DIAPHRAGM CHECK VALV...
Dry hopping has developed from being just a trend in recent years, especially in aspiring breweries from the craft beer scene, to an established technique in the entire brewing industry. Rhinegeist Brewery—located in an area called Over-the-Rhine in Cinncinati, Ohio—has undergone a huge development from 11,000 barrels a year in 2015 to more than 100,000 barrels a year in...

Quite often, customer will ask, which rating of MCB or RCDs to be chosen to protect the surge protective devices (SPD)? The answer is simple: we do not know. The fact is that different MCB has different tripping force, different designed tripping mechanism has different moving contact and static contact and their arc running systems are also different. Some 20A MCB ...

Damage Threshold Definition: Colloquially speaking, Laser-Induced Damage Threshold (LIDT) represents the critical value of a laser intensity at which an optical device can withstand without being permanently damaged. The LIDT of an optical device depends largely on the type of laser used. A Continuous Wave (CW) Laser usually causes damage through thermal effects (abso...
The city of Liverpool lies at the centre of one of the UK’s largest urban areas. Originally a port, it developed into the UK’s most important city after London during the Industrial Revolution. Liverpool has a rich cultural history, but socioeconomic discrepancies led to it becoming a deprived area, with associated health burdens. However, expert research and innovati...
With the excitement surrounding the emergence of LED lighting and displays it is becoming increasingly important to be able to measure the performance of LEDs and LED-based systems in accurate and meaningful ways. This is even more important as LEDs are increasingly used as an alternative to more traditional technologies. The intended purpose of the measurement - to info...
Human vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production environments. Traditional methods for automated defect detection do not relate directly to human perception. Accurately correlating human perceptions of defects with the informat...

Safety in potentially explosive workplaces is governed at European level by two directives: ATEX 2014/34/EU (product directive) and ATEX 99/92/EC (social directive). The first directive sets out the requirements and procedures for conformity assessment of ATEX equipment and identifies the obligations and responsibilities of economic operators (manufacturers, authorised ...
At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. In this study, we show how Raman spectroscopy, which has been studied extensively for forensic fiber analysis, is a perfect fit for this scenario because of the high selectivity of Raman signatures, non-destructi...
Brightly-colored street samples such as ecstasy tablets pose a serious challenge due to the fluorescence interference commonly associated with Raman devices that use a 785-nm laser. For this reason, handheld Raman systems that contain 1064-nm laser excitation, as opposed to the 785-nm laser excitation traditionally used, are the newest advancement in Raman instrumentatio...
Vibrational spectroscopy is a well-established, powerful tool for polymer characterization. In this application note, we’ll explore how aqueous based water-soluble polymers(10-20% solids) can be rapidly and easily measured using the i-Raman EX portable Raman spectrometer.
Raman spectroscopy is a form of molecular spectroscopy that gives specific molecular information of materials. Raman is used widely for rapid, non- destructive, non-invasive identification testing in chemical, material, pharmaceutical and biomedical research, in medical diagnostics, and increasingly by law enforcement. A limitation of Raman spectroscopy is that samples c...
