The Radiocrafts RC1180-KNX RF transceiver module is a compact surface-mount, high performance wireless communication module with embedded KNX RF protocol complying with the KNX-RF (Konnex over RF) standard of the KNX Association. The module has a UART interface for serial communication and configuration. It is pre-certified for operation under the European radio regulations for license-free use and measures only 12.7 x 25.4 x 3.3 mm with shielding. When used with a quarter-wave antenna, a line-of-sight range of 500 to 600 metres can be achieved. Operating in the 868 MHz frequency band, the RC1180-KNX meets the KNX specification and supports S, A and E modes. The physical layer complies with the relevant parts of the EN 50090 (ISO/IEC 14543-3) standard. KNX is the only open international standard for home and building control. The RC1180-KNF module can be used in smart home, building automation and building management systems, HVAC systems, automatic meter applications, and twisted-pair KNX gateways. The embedded protocol supports KNX-RF 1.1 and KNX Ready and can be used with unidirectional and bidirectional devices as well as battery operated systems.

The module supports bind of up to 64 other KNX-RF devices and uses

Scientists at Philips Research have developed what they say is the first organic light emitting diode (OLED) module that can be powered directly from the AC mains. The prototype opens the door to OLED systems that can be directly plugged into standard power outlets without the need for bulky power management circuitry. This will simplify luminaire designs for future OLED-based systems for mass-market general illumination applications.

Like LEDs, OLEDs are solid-state lighting devices that are extremely efficient light emitters, thus helping to reduce the financial and environmental cost of lighting. While normal LEDs provide very high brightness in a compact package, OLEDs emit light over an extended area. The illumination they produce is calm, diffuse and non-glaring. The thin, flat nature of OLEDs makes it possible to produce light sources in a wide variety of shapes and sizes.

Moreover, OLEDs are fully dimmable and can produce many different colours as well as whites, including the kind of white light people are accustomed to from traditional light sources. This makes them an extremely attractive option for general illumination.

However, up to now OLEDs have required a low-voltage DC power source due to their physical characteristics. By contrast, the AC-powered white-light module developed by Philips Research can be plugged directly into a mains wall socket.
Eliminating the need for driver electronics could create many advantages for luminaire manufacturers. It reduces the number of components in the finished product, which makes system integration and assembly simpler, improves end-product reliability, and reduces time to market. Moreover, it increases design freedom and expands the range of potential OLED applications.

National Instruments has released a new vision module for the PXI platform that provides a high-performance parallel processing architecture for hardware-defined timing, control and image pre-processing. The new NI 1483 Camera Link adapter module, in combination with an NI FlexRIO field-programmable gate array (FPGA) board, allows vision and control algorithms to be embedded directly in FPGAs. Engineers and scientists can use FPGAs to process and analyze an image in real time with little to no CPU intervention. Additionally, using FPGAs helps eliminate the need to design custom hardware.

Engineers and scientists can use FPGAs to perform operations by pixel, line or region of interest. The FPGAs can implement many image processing algorithms that are inherently parallel, including fast Fourier transforms (FFTs), thresholding and filtering. The NI 1483 is ideal for optical coherence tomography (OCT) and high-speed control systems for applications such as laser alignment and sorting. The module is also suitable for acquisition from Camera Link devices with custom tap configurations and high-resolution sensors with more than 10 megapixel (MP) resolution requiring hardware-based pre-processing.

The new module supports base-, medium- and full-configuration Camera Link devices as well as 80-bit 10-tap configurations, all up to 85 MHz. This design gives engineers and scientists the ability to tailor image acquisition when using custom image sensors. The 85 MHz measurement capability supports the Camera Link standard specification to its fullest, creating an excellent fit for users working on applications with high frame rates.

The module also integrates several I/O options, including four TTL I/O lines, two opto-isolated inputs and one quadrature encoder input, in addition to the many modular I/O and industrial communication options available for the PXI platform. Engineers and scientists can use the LabVIEW FPGA module to tailor the NI FlexRIO hardware without knowledge of low-level hardware description languages or board-level design. By using the LabVIEW graphical programming environment, engineers and scientists vastly reduce their development time while making use of existing VHDL IP.
