Codes and markings, from best-before and lot dates to EAN or data-matrix barcodes to serial batch numbers and various unique identifiers, are there to ensure traceability and product safety, to protect consumers and to avoid counterfeiting. There are many different print techniques that manufacturers can choose, such as continuous inkjet, thermal transfer or laser coding. All of these techniques have their advantages and challenges.
Multi-degree-of-freedom (DoF) mechanisms are widely required in micro or macro manipulation fields as well as in optronics functions. Commonly available mechanisms may be divided into two main categories. The first is industrial robots (serial or parallel). These offer a large range of motion in rotation and translation. Their resolution is usually limited in the sub-millimetre range.
Automobiles, aircraft, marine vehicles, uninterruptible power supplies and telecommunications hardware represent areas utilising series-connected battery stacks. These stacks of individual cells may contain many units. In such systems, it is often desirable to accurately determine each individual cell’s voltage. Obtaining this information in the presence of the high ‘common-mode’ voltage generated by the battery stack is more difficult than might be supposed.
Technical article: compact and efficient piezo actuation chain for aeronautical applications download
Many past and ongoing studies are focusing on the use of piezo-actuators for aeronautical applications. One of the trendiest topics is the use of such devices for active flow control in aircraft in order to reduce fuel consumption and noise. However, the implementation of such systems in aircraft suffers a lack of maturity with respect to aeronautical constraints, which are high efficiency, compactness and light weight.
This guide from Sensonics explains the basics of vibration and expansion measurement techniques relating to turbine and auxiliary plant equipment. The guide starts with an introduction to the basic transducers available for plant mounting with associated options and details the various measurement techniques used as standard throughout the power industry.
This paper details a test bench design and the results obtained with CNES on two-piezo ceramics stacks from two distinct suppliers. Integration into dedicated cryo actuators is also proposed as well as the associated cryo performances. The use of such cryo-compatible actuators is detailed in a fine steering tip-tilt mechanism designed to reach very high resolution and stability for the ESA EChO space mission.
In wet chemical analysis, complete dissolution of the samples is required for the determination of the total concentration of elements. Especially for silicate-containing samples, the usage of hydrofluoric (HF) acid is a necessity. In order to digest and extract all metals quantitatively from matrices containing silicates and oxides, normally digestion with hydrofluoric acid is carried out in a two-step procedure.
A design office’s ability to assess and control vibration and noise levels generated by an electric motor during the design stage is a key asset — particularly for ensuring the end user’s comfort. This is especially true for electric powertrains on electric vehicles, and also when looking for higher performance in terms of power, efficiency, reliability, and — obviously — reduced material costs linked to the supply of magnetic equipment. During the past three years in the context of ...
