With more and more phone users switching to DSL or cable networks and using mobile phones instead of landline phones, there is a growing scarcity of fixed telephone lines that are compatible with conventional analogue modems. To  remedy this situation, eDevice has developed the WireX machine-to-machine wireless communication converter, which it claims is the first mass-market communication converter for machine-to-machine links. According to eDevice, installation is easy and users with a data volume of 1 MB per month can reduce their communication costs by more than 50% by switching from a dedicated phone line to WireX.

 

The WireX converter allows legacy equipment with embedded analogue modems to be communicate using a mobile telephone network (GSM or GPRS) instead of the conventional telephone system. It is designed for to be installed directly by the end user and does not require any changes to the existing legacy device; the user only needs to disconnect the phone cable from the wall and plug it into the WireX adapter. The data previously transferred over the phone link is then automatically transmitted over a GSM or GPRS network using phone line emulation.

 

In the home environment, WireX can be used with various types of existing devices equipped with analogue modems, including remote patient monitors, telecardiology monitors, alarm and security systems, and TV set-top boxes. In a SOHO or small business environment, it can be used to convert point-of-sale equipment, energy metering systems, and security and access control devices to wireless communication.

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.
