Available in either on/off or bi-level configurations, these fixtures offer energy savings and lighting solutions where constant lighting is required, like a stairwell, or where light is not required when an area is not in use, like a bathroom. The adjustable standby levels of the bi-level configuration are 5, 10, 20 or 30 percent to provide a certain level of constant light without draining energy.
The fixtures are constructed out of steel or stainless steel and are typically painted white with a white acrylic lens. The Ophelia series is available in lengths between 2 and 4 ft with either single or double lamps fitting either T5 or T8 lamp sizes.
Other features of the Ophelia series include a 100hr lamb conditioning circuit and an emergency back up that will run one lamp for 90 mins in a power outage. The motion sensors are custom made by Watt Stopper.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
