Features

Optical Fiber Backlighting

Lumitex, Inc. (Strongsville, OH) released a family of products — BendiGloTM, HoloGloTM, CircleGloTM, and Selective LightingTM — based on their existing UniGloTM technology to backlight shapes such as rectangles, ovals, circles, semi-circles, holes, and other unusually shaped geometries. Optical fiber is mounted on a back reflector to create lighting panels of 0.33 mm. BendiGlo is for hard-to-reach areas in membrane switches; HoloGlo follows paths around/between shapes and die-cut holes; CircleGlo is used in one to three layers for circular areas with a hole; and Selective Lighting creates selective area panel lighting.

LED Drivers

Endicott Research Group (Endicott, NY) released the Smart ForceTM family of LED driver solutions for high-bright LEDs (HBLEDs) used in LCD backlighting applications. Available as a LED driver board or a complete kit including driver board and LED rails, the product has input voltages of 12 V, 24 V, or 48 V (measuring 33 × 60 mm) in single-, dual-, or three-channel versions. Employing a DC-DC boost to provide voltage to a constant current driver and LED rail, the driver boards’ input voltages range from 5 V to 48 V. Standard features include separate enable/disable and PWM dimming controls.

Test Module

EXFO Electro-Optical Engineering Inc. (Quebec City, Canada) introduced the FTB-8105 T-Carrier/PDH Transport Blazer test module as part of the Transport Blazer line. The unit tests digital-signal levels and plesio-synchronous digital hierarchy electrical rates as well as SONET/SDH rates up to 155 Mbps, and is suited for time-division-multiplexing field service deployment and maintenance applications. The module may be combined with the FTB-8510 Packet Blazer Ethernet module for Ethernet-over-TDM network deployments.

Detector Array

The Andor iDus InGaAs detector array system from Andor Technology (Belfast, N. Ireland) is a spectroscopic detector with 512 or 1,024 element linear photodiode arrays for near-infrared spectroscopy. The resolution covers wavelengths from 800 nm to 2,200 nm. Features include a peak QE of less than 80% with reduced noise, thermo-electric cooling to -85°C, and USB 2.0 connectivity. A hermetic seal vacuum is guaranteed. Applications include Raman at longer wavelengths, LIDAR, and photoluminescence.

Leslie Molzahn, Operations Engineer, Dryden Space Flight Center, Edwards, CA

Leslie MolzahnSupersonic speed would allow travelers to cut significantly their travel time. However, because of the resulting sonic booms, the Federal Aviation Administration (FAA) and similar associations restrict supersonic travel to transoceanic only. Gulfstream Aerospace Corp. (Savannah, GA) partnered with NASA Dryden in a commercial investigation of the Quiet Spike, a sonic-boom suppression system. Leslie Molzahn was part of Dryden’s investigative team
