Traditional methods of remote monitoring and control using RTUs and SCADA systems are well entrenched in the water industry. But there is a wave of new technologies available now that have the potential to dramatically change the way we think and act in our endeavours to optimise our scarce water resources.
ow do you drive innovation? Do you lead with intuition shaped by your experiences? Or do you take a more scientific approach, relying upon strategic plans, business models and market studies? Michael Raynor of Deloitte Consulting says: ‘Judgement is a significant part of the equation, but the facts define the parameters of the choices you face. Sure, the numbers matter, but only at the margin.’
Over the years, dispersive Raman spectroscopy has increasingly been implemented for material identification thanks to its portability and sampling flexibility. When choosing a Raman instrument, one of the primary concerns is the wavelength of the laser that is integrated into the Raman spectrometer system. Even though the Raman shift of any material is only related to the material’s specific chemical structure and is independent of the excitation wavelength, different wavelengths have ...
When we think of a gearhead, we tend to assume that it is incompressible and rigid. The truth is it still bends, compresses and has elastic properties. This has an effect on the difference between the perceived motion (encoder counts) and the actual motion of a drive system — we are not where we are supposed to be. According to Mark Gibbons of maxon motor, when measuring anything we need to keep in mind how the instrumentation works and what are its limitations.
The aim of an alarm system is to prevent, or at the very least minimise, physical and economic loss to plant or people through operator intervention in response to a plant condition that has occurred, thus making the necessary corrective action and optimising production. Selection and prioritisation of alarms, and deciding which are deemed ‘critical’ that need to be displayed on an alarm annunciator to guarantee operator response under all scenarios, is not a trivial task. This paper ...
PC-board layout determines the success or failure of every power supply project. It sets functional, electromagnetic interference (EMI) and thermal behaviour. Switching power supply layout is not black magic, but is often overlooked until it is too late in the design process. Fortunately, physics is on your side.
Aircraft corrosion is a never-ending challenge where prevention and control play the fundamental role of ensuring the airworthiness requested. As this paper from Envirotech explains, corrosion prevention involves design optimisation and proper material selection, as well as correct finish specification and effective maintenance, inspection and repair.
Tuned mass dampers are simple and efficient devices for the suppression of machine tool chatter, which is one of the principal effects limiting productivity in many machining processes. However, their effectiveness depends on a proper tuning of the damper dynamics to the dynamics of the machine. This involves the dynamic characterisation of the machining process, in order to identify the critical resonance frequency.
This white paper from Omniflex explores the requirements of monitoring and logging as required for compliance with ABGR and other ratings in Australia, and the real benefits that can be achieved by using remote monitoring and control to ensure compliance and to optimise the operation of buildings. The use of remote monitoring services as a solution for smaller buildings without a building management system is explored.
This white paper focuses on a bistable harvester designed and invented by the SYMME laboratory using amplified piezoelectric actuator (APA) technology and the industrial know-how of Cedrat Technologies.
As with standard desktops and laptops, protection from viruses, malicious users and general malware is of paramount importance for embedded devices. Additionally, you many need to preserve the runtime images of embedded systems by protecting them against write operations; because Windows Embedded Standard 7 is based on Windows 7, depending on your configuration, many of the same security vulnerabilities will apply.
White paper: active cardiac stabiliser — first in-vivo experiments using a robotised device download
Off-pump coronary artery bypass grafting (CABG) is still today a technically difficult procedure. In fact, the mechanical stabilisers used to locally suppress the heart excursion have been demonstrated to exhibit significant residual motion. Cedrat Technologies proposes a novel active stabiliser that is able to compensate for this residual motion.
Low-power operation of electronic apparatus has become increasingly desirable. Medical, remote data acquisition, power monitoring and other applications are good candidates for battery-driven, low-power operation. Micropower analogue circuits for transducer-based signal conditioning present a special class of problems. Although micropower ICs are available, the interconnection of these devices to form a functioning micropower circuit requires care.
Modern CAE software allows engineers to investigate a multitude of design variations that could not possibly be considered using conventional physical prototypes. This paper first illustrates parametric methods for automatically creating virtual prototypes of electromechanical actuators using the AMPERES and MAGNETO programs from Integrated Engineering Software. It also refers to a specific case study that shows how the Tecplot Chorus program can assist in determining optimal design ...
Are brushless motors just a technology fad or can they be of real benefit to design engineers? As maxon motor explains in this article, brushless DC motors are more popular than brushed motors at the moment, but the fundamental question when choosing a motor is ‘what does it need to do?’
