Linear Photodiode Array

Sensors Unlimited, Inc. (Princeton, NJ) introduces the LC Series Linear Photodiode Array. The SU256LCS-2.6T2 detector array is available with 256 elements of extended response InGaAs material and is designed for wavelength range from 0.9 microns to 2.6 microns. The LC photodiode array package design includes a two-stage TEC and thermally optimized materials for multi-channel spectrometers that require high sensitivity, low power consumption, and long-term stability. Applications include biomedical analysis and industrial process control.

Wafer Scanner

The Wafer Scanner 3840™ from Rudolph Technologies (Flanders, NJ) is for inspection and metrology of back-end semiconductor manufacturing processes, including bumping, probing, sawing, and dicing. The WS 3840 Inspection System uses Rudolph’s laser triangulation technology to provide fast and accurate measurements of bump height and coplanarity. A time delay integration (TDI) line scan camera provides image-based macro defect inspection for wafer surface and bump, and measures 2D bump characteristics, such as diameter, shape, and placement accuracy.

Green Energy for the Battlefield

The amount of energy the United States consumes increases every year and this growth in energy consumption outpaces energy production. To fill this gap, the U.S. imports 35% of its energy. More importantly, the U.S. imports over 60% of its total oil consumption. Added to this, 70% of this energy is from non-renewable sources.

Creating Patterned Multispectral Filters

In recent years the explosion in demand for multispectral imaging has coupled with the industry’s insatiable need for weight reduction, thereby greatly increasing the demand for more sophisticated approaches to producing optical filters that are used in these systems. One method to meet the challenge of reducing the weight of a multispectral system is to eliminate beam-splitting optics and multiple detectors by patterning a filter array on a single substrate, or directly on the CCD itself.

Omniscient Code Generation for 8-, 16- and 32-bit Microcontrollers

C-language programs are usually developed by teams of engineers who are often geographically dispersed, leading to redundant code and inconsistent variable declarations between modules. Traditional compilation technology compiles each module separately with no regard for what goes on in the other modules and with no information about how pointers, stacks, variables and functions are used throughout the whole program. Traditional compilers tend to over-allocate memory space for pointers, stacks and registers. They are unable to fully exploit the wide variety of memory maps, and register and stack configurations available in today’s microcontrollers. All too often, the programmer must resort to manual optimizations that compromise portability (Figure 1).

Using AdvancedTCA and MicroTCA in High-Availability Military Systems

The complexity of military and aerospace systems is growing — more components, interfaces, power, bandwidth, processing, features, and data — and these systems are being networked to form even more complex “systems of systems.” Modern networkcentric systems can contain hundreds, even thousands of electronic modules.
