Teardown reveals PrimeSense in Google’s Tango By Peter Clarke A deconstruction by iFixit of Google’s Project Tango depth-sensing prototype Android phone has revealed the presence of the PS1200 ‘Capri’ 3D sensor data processor from PrimeSense Ltd. (Tel Aviv, Israel). The teardown also reveals two Myriad 1 vision processors from Movidius Ltd. (Dublin, Ireland) and a Snapdragon 800-series MSM8974 application processor. Although PrimeSense was not mentioned as one of the original collaborators in Project Tango, the startup was the developer of the Kinect 3D depth sensing system used with Microsoft Xbox 360. PrimeSense was acquired by Apple for about $345 million late in 2013. The Project Tango prototype from Google has been created in partnership with OmniVision Technologies Inc. (Santa Clara, Calif.), inertial MEMS sensor provider Bosch; Movidius Ltd. (Dublin, Ireland) the vendor of the Myriad 1 vision processor; and Paracosm (Gainsville, Florida), vendor of software that converts 3D scans into computer models. The Capri PS1200 SoC works with an infrared illuminator that sends modulated IR light out and then an off-the-shelf CMOS image sensor to read the coded light back from the scene. The PS1200 then processes the coded IR patterns to produce a depth-image of the scene. A Dragon Fruit for test and measurement: Red Pitaya comes to Europe By Christoph Hammerschmidt Fans of Arduino, Raspberry Pi or Cubieboard will like this: Startup company Red Pitaya transfers the open approach of these single-board computers to the Test and Measurement arena. The company now sets its foot on European soil. As the first step, it signed an exclusive distribution agreement with RS Components. Since its inception in mid-2013, Red Pitaya has developed an ecosystem of devices and software designed to support an open approach to measurement tasks of all kinds. The ambition is high: The platform available for less than $500 could seriously compete against multiple expensive laboratory instruments - plus, its open approach fosters the development of innovative applications for segments where hitherto no custom offering exists in the market. The entire Red Pitaya ecosystem is centred on a single board, reconfigurable, open instrument platform not much bigger than a credit card. The processing power is provided by a Xilinx Zynq SoC which combines an ARM Cortex-A9 microcontroller with the flexibility of an FPGA. The board offers a total of six analogue I/O ports of which two are suited for RF signals. 16 general-purpose I/Os, an Ethernet port and a Micro SD slot ensure connectivity and expandability. In terms of software, a cloud marketplace named Bazaar offers a set of open-source measurement applications including an oscilloscope, a spectrum analyser and an arbitrary waveform generator. Measurement results can be displayed on a PC or tablet computer running a web browser. A repository of corresponding open-source code and tools enables designers to share and collaborate in developing applications. The software is based in the GNU/Linux operating system; the environment supports a variety of software interfaces and languages including C/C++, scripting languages and HTMLbased web interfaces. First commercial products can be expected later this year, RS Components says. 12 Electronic Engineering Times Europe May 2014 www.electronics-eetimes.com
