Just in - the results of our annual Trend Watch Sensors Survey of design engineers, who specify a wide range of sensor technologies in their applications, from basic proximity and photoelectric sensors to more advanced vision systems and energy-harvesting sensor networks. In general, respondents see sensors as growing in importance, with 56 percent saying they expect to see the use of sensors in their designs increase in the next three years. Half of the survey respondents design products for the industrial market. The balance of respondents works in industries as diverse as automotive and aerospace to packaging and healthcare. A full two thirds noted that in particular vision sensors and systems and wireless sensors will become increasingly more important in their design work. Some 15 percent of respondents noted that more traditional proximity, linear displacement and photoelectric sensors also will play a more prominent role in their design work. Hands down, the hottest trend noted in the survey results is wireless sensor networks, with 60 percent of the respondents saying that they see this technology heating up in the next 12-18 months, thanks to greater reliability and easy-to-use, plug-and-play connections. There is also the potential with wireless for significant savings when it comes to installation costs. When selecting a sensor, respondents said that reliability, accuracy and durability/ruggedness are the top three charactertistics, while product support and availability are critical when selecting a particular supplier. On design engineers' sensor wish list is more comprehensive data sheets and technical documentation, especially with regard to new products, as well as the availability of cost-effective sensors that meet the rigors of their applications. "We're looking for the right functionality with good pricing," one respondent noted.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
