This battery power device does not play MP3 tunes, but it does have an audible alarm output. The alarm sounds when a film of water bridges the contacts of the unit’s integrated electronic sensor. However, condensation or high humidity will not cause the sensor to trigger the alarm. Operating from a 9V battery that lasts about one year, the unit also provides an audible low battery “chirp” to warn of a low-battery condition. Typical applications include basement sump pumps, drain areas and sprinkler systems in residential homes, as well as commercial buildings.
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.
