The MAX21000 is a low power, low noise, 3-axis angular rate sensor that delivers unprecedented accuracy and sensitivity over temperature and time. It operates with a supply voltage as low as 1.71V for minimum power consumption. It includes a sensing element and an IC interface that provides the measured angular rate to the external world through a digital interface (I2C/SPI). The IC has a full scale of ±31.25/±62.50/±125/±250/ ±500/±1k/±2k degrees per second (dps) and measures rates with a finely tunable user-selectable bandwidth.

It´s possible to receive the latest technical and safety datasheets of Kontakt Chemie products comfortably into your e-mail box.
As chemical agents belong to a highly regulated segment (on-going REACH) process), it´s necessary that you always had the actual version of technical- and mainly safety datasheets for agents which you use. Especially for larger companies using a many chemical agents it´s a considerable load – to watch legislative changes and to search for the latest version of documents.
That´s why company CRC – producer of Kontakt Chemie sprays, brings a useful and free service „My CRC“. By means of „My CRC“ the end user has ensured the 100% latest documentation in case of legislative changes as is the hazard classification or changes of European law. These changes don´t affect the product production or its availability but the actual documentation version is vital from reason of possible criminal responsibility.
After a simple registration on the http://www.crcind.com/crc/ – website – by clicking on the „My CRC“ logo, you´ll receive an e-mail with login. In the next step after signing-in (by clicking on the “My CRC” logo) select a language for required documents – in the left bottom part of page. In the upper portion of the website you can select a country and language for work on this web. If the given country is missing, we recommend you to choose „Others/ English“. The documents are in the alphabetical order and you can check the column in the right at every document, which you´re interested in. Finally, after clicking the „My selection“ button, it´s possible to choose whether you wish to receive on your e-mail these documents (immediate e-mail with links to these documents) or you wish to receive only changes/ updates of these documents (if occur in the future).
We believe, that this function will make your work more pleasant and easier. In case of questions, please contact us at firstname.lastname@example.org.

Boris Landoni present us an overview of todays microcomputer boards able to run Linux. He writes:
Today we present an overview of today’s market offering regarding ARM RISC microcomputer able to run a GNU/Linux distribution. And once again, this is just the beginning.While the growth of such a device segment was predictable, it wasn’t easy to predict such an explosion. In fact we now have an heterogeneous set of options, with different characteristics, requiring a different approaches to for the optimization of the GNU / Linux operating system. In this post we’ll try to present, on the one hand, the unifying elements of different devices and, secondly, to classify each device based on its best use cases.Let’s begin to point out a first list of devices to analyze, new ones appear every day but we’ll deal with them later.The ones we feature on this post are the following:

The TS3310 is a low power boost converter with an industry-leading low quiescent current of 150nA, enabling ultra long battery life in systems operating from a variety of battery sources. The TS3310 is the industry’s only boost converter to specify its no-load supply current with an actively switching boost engine, providing a more accurate picture of supply current during normal operation. The TS3310 boosts input voltages from 0.9V-3.6V to one of eight user-selectable output voltages ranging from 1.8V to 5.0V. The TS3310 includes two outputs: (a) an always-on primary output and (b) a user-enabled, load-switched secondary output designed to power burst-on loads operating at low duty cycles, such as a ZigBee radio.
