Next-generation wireless prototyping platform National Instruments has announced an integrated software defined radio solution for rapidly prototyping high-performance, multichannel wireless communication systems. The NI USRP RIO platform is built on the LabVIEW RIO architecture and combines a high-performance 2 x 2 multiple input, multiple output (MIMO) RF transceiver capable of transmitting and receiving signals from 50 MHz to 6 GHz with an open LabVIEW programmable FPGA architecture. Wireless engineers can use this technology to rapidly prototype realtime wireless communications systems and test them under real-world conditions. They can also prototype more capable wireless algorithms and systems faster and reduce time to results using the only complete platform to take full advantage of a graphical system design approach. The USRP RIO family delivers high-performance, real-time processing capability with the Xilinx Kintex-7 Series FPGA, low latency with the PCI Express connection to a host computer and small size (1U half wide, 19 inch rack mountable). USRP RIO is ideal for a wide range of application areas including 5G wireless communications research, active and passive radar development and exploration, communications intelligence, connected smart devices and more. The USRP™ (Universal Software Radio Peripheral) is already a popular platform for research spanning industry and academia as it empowers researchers to rapidly iterate on designs via programmable software. For example, a recent Lund University announcement highlights a 5G research application focusing on massive MIMO — a technology being considered for 5G communication. National Instruments www.ni.com Piezoelectric drop-on-demand printheads target advanced manufacturing Inkjet technology developer Xaar has released a range of piezoelectric drop-on-demand printheads designed specifically for advanced manufacturing applications. The Xaar 1002 AMp is capable of very small drop fluid deposition on an industrial scale, able to consistently jet droplets as small as 1 pL for the production of fine features, patterns and coatings. The combination of highly accurate, very small drops and high reliability enables the industrialisation of advanced manufacturing processes in sectors such as display, PCB, semiconductors and photovoltaics. The 1000 optimised geometry nozzles ensure accurate jetting and consistent drop volume across the printhead, even with fluids that have a high solids content, including metallic particulates. The company’s TF Technology ensures a uniform temperature across the whole printhead for consistent drop formation and repeatable fluid deposition. Drop size and formation can be optimised for variable drop volumes within a single pattern to control coating thickness and avoid potential optical effects such as banding and Mura. If required, multiple Xaar 1002 AMp printheads can be configured into large jetting arrays. Xaar www.xaar.com CAN-WiFi-gateway leverages smartphones for data visualization With IPEhub2 and the IPEmotion App, Ipetronik enables users to visualized CAN data on a smartphone or tablet using a WiFi connection. IPEhub2 acts as CAN-WiFi-Gateway and transfers CAN bus data (from the company’s CAN modules or the vehicle CAN bus) using WiFi. Two CAN bus data streams are converted to encrypted WiFi data and wirelessly transferred to a tablet or smartphone running the IPEmotion App according to WiFi Standard 802.11 a/b/g/n. IPEmotion 2014 features an IPEmotion App export, so custom IPEmotion configurations can be used in the Android application conveniently. Data visualization type and extent (curve, bargraph, alphanumeric, LED) are to be set individually via IPEmotion App. Parallel to wireless data transfer, traffic data are stored on the FIFO of the SD card included in IPEhub2. Customers can choose between SSID (Service Set Identifier) and WPA2- (WiFi Protected Access 2) encryptions; WPS- (WiFi Protected Setup) function is supported for initial setup. The IPEhub2 module uses a gold-anodized aluminum enclosure measuring 106x43x62mm, it is protected to IP54 and can operate in the -40 to +85°C temperature range. It runs from a 9VDC to 36 VDC voltage supply, drawing 4.0 watts typically. Two multi color status LEDs indicate operating states of WiFi (signal strength) and data storage (memory usage). IPEhub2 also supports Access Point functionality with DHCP server and a CAN2 terminating resistor that can be connected via software.
