CERN launches Open Hardware initiative

Geneva, 7 July 2011. Four months after launching the alpha version, CERN1 has today issued version 1.1 of the Open Hardware Licence (OHL), a legal framework to facilitate knowledge exchange across the electronic design community.

In the spirit of knowledge and technology dissemination, the CERN OHL was created to govern the use, copying, modification and distribution of hardware design documentation, and the manufacture and distribution of products. Hardware design documentation includes schematic diagrams, designs, circuit or circuit-board layouts, mechanical drawings, flow charts and descriptive texts, as well as other explanatory material.

LiteOS - OS for sensor networks

LiteOS is an open source, interactive, UNIX-like operating system designed for wireless sensor networks. With the tools that come with LiteOS, you can operate one or more wireless sensor networks in a Unix-like manner, transferring data, installing programs, retrieving results, or configuring sensors. You can also develop programs for nodes, and wirelessly distribute such programs to sensor nodes.

The LiteOS 2.0 is the latest beta version of LiteOS. It runs on the following platforms: X86/Windows XP/Vista or Linux, MicaZ or IRIS as the target mote platform, and MIB510/MIB520 as programming boards.
Funding acknowledgement: The LiteOS Project is currently supported by NSF grant CNS-0953238 (2010-2015), and was supported by NSF grant CNS-0626342, and Vodafone Fellowship (2007-2009).
