The T7 is a sealed, rugged, high resolution
inclinometer based on MEMS accelerometer technology. It operates over a full
360 degrees of rotation and communicates by either a serial or CAN interface.
The T7 was specifically designed for concentrating solar power applications and
can be easily mounted on a mirror or trough assembly to provide angular
position relative to gravity. The product is designed for harsh outdoor
environments by utilizing a UV stabilized polymer material and sealing to meet
IP67 standards. The T7 is also fully programmable to provide the best
performance for each solar application. The T7 provides a very simple means of
determining the exact angular position relative to gravity for a rotating
member in a concentrating solar application. Concentrating solar applications
require very precise positioning of the moving reflective member relative to
the sun in order to provide maximum conversion efficiency. The T7 solves this
requirement by supplying high resolution and high accuracy information to the
solar control loop such that the concentrating solar application can
continuously peak its energy production as the sun moves from dawn to dusk. The
T7differentiates from its
competition by offering very high angular accuracy (0.1 degrees) over a full
360 degrees of rotation, high resolution (up to 36,000 positions per 360
degrees), low cost ($225 single unit), positional stability over 0 to 70 C
temperature range and the choice of either RS232 or CAN
communication. Competition offers high angular accuracy over a limited
angle of rotation, lower resolutions, much higher single unit costs and outputs
are many times not serial communication but rather analog or current loop
outputs. The T7 provides the exact requirements for Solar Tracking Systems.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
