Avionics Interface Computer

Data Device Corporation (Bohemia, NY) has introduced the Avionics Interface Computer (AIC), providing a scalable, programmable, and portable platform to develop and test MIL-STD-1553 and ARINC 429 system applications via an Ethernet network. The AIC features 2 PMC and 2 Mini- PCIe expansion sites, allowing users to select interface boards optimized for their specific application and connectivity needs. An onboard Intel® Atom™ E3845 Quad Core 1.91GHz processor provides programming flexibility and simplifies connectivity by automatically bridging messages in real-time between Ethernet, ARINC 429, and MIL-STD-1553. The BU-67121W AIC also lowers the complexity and cost of many long discrete cables by locating the 1553/429 interfaces close to onboard electronics, and using the Ethernet interface to provide network access and control from the test lab.

Adaptive IF Relay XMC

Pentek, Inc., (Upper Saddle River, NJ) has introduced the newest member of its Cobalt® line of XMCs (Switched Mezzanine Cards). The Model 71624 dual channel, 34 signal, adaptive IF (Intermediate Frequency) relay XMC with a Virtex- 6 FPGA accepts two IF analog input channels, modifies up to 34 signals, and then delivers them to two analog IF outputs. Any signal within each IF band can be independently enabled or disabled, and changed in both frequency and amplitude as it passes through the module. The Model 71624 features 34 digital down converters (DDCs), each independently tunable across a 100 MHz input IF range, handling signal bandwidths from 20 kHz up to 312 kHz. The DDCs deliver 34 baseband signals to the host computer, which determines how each signal is dropped, replaced, or changed in amplitude and frequency. The modified signals are then combined and delivered as an analog IF output.

Brushless DC Motors

BEI Kimco Magnetics (Vista, CA) has developed new frameless brushless DC motors in multiple designs for a variety of applications including robots and remotely piloted military vehicles. These new motors provide operational efficiencies in excess of 90% by utilizing proprietary low magnetic circuit design techniques to extend battery life. Other important features include a frameless motor design composed of two pieces a rotor and stator. This design makes it easy to integrate into a customer’s existing assembly, minimizing the need for extra components and reducing overall weight. Motors range up to 20" in O.D. with torques in excess of 50Nm and operational speeds beyond 70K rpm.

Optical Profiler

Zygo Corporation (Middlefield, CT) has introduced the ZeGage™ Plus optical profiler, a full-featured instrument for the 3D measurement of surface topography and roughness. The ZeGage Plus utilizes ZYGO’s proprietary Mx™ software, for enhanced data visualization and quantification of step heights, texture, and volumetric applications. ZeGage Plus profilers with optional automated XY sample stages have the added ability to combine overlapping measurements for the characterization of larger areas. Many of ZYGO’s extensive list of parfocal objectives can be used with ZeGage Plus profilers, from 1.4X to 50X, as well as 1X to 10X long working distance, and a 5X super- long working distance lens.

Laser Modules

LASER COMPONENTS‘(Bedford, NH) FLEXPOINT® laser module series now includes dot and line lasers with 488 nm, in addition to 405 nm and 450 nm wavelengths in the blue spectral range. Depending on the beam profile, the output power amounts to up to 40 mW. Due to the narrow-banded emission of 488 nm ±2 nm, these laser modules are optimally suited for fluorescence applications, spectroscopic applications, and particle measurements. Further applications include biomedical and medical technology.

VCSEL-Based Miniature Line Generator

Princeton Optronics Inc. (Mercerville, NJ) has introduced a VCSEL-based miniature line generator. The wavelength of the line generator is in the 820- 840nm range, has a 20mW CW power output, a fan angle of 80 degrees, line uniformity of 75-85%, a 1/e2 linewidth of 2.5mm at a distance of 50 cm. The size of the line generator is 4x6x5mm. Such products can be made using Princeton Optronics VCSELs at wavelengths from red to 1064nm, with output power up to several hundred mW. The line generators are used in applications such as machine vision, consumer electronics and instrumentation.

Compact UV Lasers Could Spot Dangerous Substances from a Distance

For soldiers in the field, the ability to identify an object or substance based on how it responds to light could mean the difference between life and death. They could, for example, determine from a safe distance if an approaching person or vehicle is carrying an explosive device or dangerous biological agent.
