Energy Micro has added a generic low
energy sensor interface to its EFM32 microcontroller product family. The
Lesense function block enables autonomous monitoring of up to 16 external
sensors in the microcontroller's sub-microamp Deep Sleep mode.
Able to run independently of the EFM32's ARM Cortex(TM)-M3 core, Lesense can be
used to create highly integrated, ultra low power, sensor solutions.
Particularly suitable for battery operated systems, the sensor interface is
designed to operate with virtually any type of analog sensor control scheme,
including capacitive, inductive and resistive types.
Among a variety of uses, Lesense can be configured to support autonomous
capacitive touch pad- and slider based products, and gas and water metering
products relying on inductive rotation sensors.
The Lesense function block will first be made available in Energy
Gecko microcontroller family, sampling and in volume during Q1'2011. Pin and
software compatible with the bigger Gecko microcontrollers, the Tiny Gecko
provides users with a wide range of low power peripheral function blocks,
including an 8-channel, 12-bit ADC using 350ยตA at full resolution and
1Msamples/sec conversion rate, and a low energy UART consuming as little as
150nA, and a new 8x20 segment LCD controller.
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 ฃ100 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.
