Techs of the Week

A linear illumination system based on a highly reflective external enclosure improves light efficiency and brightness when utilizing fluorescent lamps, light emitting diodes (LED), laser diodes, organic LEDs, electroluminescent strips, or high-intensity discharge lamps as the light source. The system provides a critical advantage for applications requiring extremely efficient light sources of high brightness (such as optical scanners and photocopiers). Additionally, this technology provides for efficient light extraction and high output radiance from narrow openings--as required in the very thin waveguides utilized in flat panel displays. This improved illumination system may be combined with optical elements of various designs or shapes to produce even more complex illumination systems. Click here for more info.

Program Injects Random Faults for Testing Computers

JIFI (Jet Propulsion Laboratory’s Implementation of a Fault Injector) is a computer program for studying the ability of a computer to tolerate, detect, and/or recover from faults (that is, bit errors). JIFI affords the capability to inject faults into user-specified central- processing-unit (CPU) registers and memory regions with uniform random distributions in location and time. This capability makes it possible to study the fault sensitivity of either a computer regarded as a complete system or of a specified component of hardware or application software. JIFI operates at the application level and is easy to use. In contrast, prior fault-injection software operates at a lower level and is more difficult to use. JIFI includes fault-injection, profiling, output- verifying, and classifying subprograms that constitute parts of an easy-to-use software interface for performing fault-injection experiments and analyzing the resulting data. JIFI generates a fault-injection-result output file for each run. Data from massive fault-injection campaigns can be collected and processed automatically.
