Multicore® LF600, a halide-free, no-clean Pb-free solder paste from Henkel (Düsseldorf, Germany), has been designed for humidity-resistance, making it best suited for varying manufacturing climates. Its formula allows for printing and reflow performance in regions where temperatures...

Inphi® (Westlake Village, CA) released the INSSTE32882, a JEDEC compliant Double Data Rate (DDR3) Configurable Integrated Register device from the Inphi ExacTik® Family of timing devices. The INSSTE32882 supports all existing DDR3- 800, DDR3-1066, and DDR3-1333...

An electronic unit denoted the Miniature Intelligent Sensor Module performs sensor signal conditioning functions and local processing of sensor data. The unit includes four channels of analog input/output circuitry, a processor, volatile and nonvolatile memory, and two Ethernet communication ports, all housed in...

&A synthesis route has been developed for the commercial manufacture of single- source precursors of chalcopyrite semiconductor absorber layers of thin-film solar photovoltaic cells. The semiconductors in question are denoted by the general formula CuInxGa1–xSySe2–y, where 0 ≤ x...

A document discusses the continuing development of a navigation system that would enable a spacecraft to approach Mars on a trajectory precise enough to enable the spacecraft to land within 1 km of a specified location on the Martian surface. This degree of accuracy would represent an...

A report proposes that cylindrical asymmetrical capacitors (CACs) be used to generate small thrusts for precise maneuvering of spacecraft on long missions. The report notes that it has been known for decades that when high voltages are applied to CACs in air, thrusts are generated — most...

A paper discusses techniques for protecting against faults in spacecraft designed and operated by NASA's Jet Propulsion Laboratory (JPL). The paper addresses, more specifically, faultprotection requirements and techniques common to most JPL spacecraft (in contradistinction to unique, mission specific...

A computational method, SimLearn, has been devised to facilitate efficient knowledge discovery from simulators. Simulators are complex computer programs used in science and engineering to model diverse phenomena such as fluid flow, gravitational interactions, coupled mechanical systems, and nuclear,...

A team from MIT has demonstrated wireless power transfer, which would enable cell phones, MP3 players, laptops, and other portable electronics to charge themselves without being plugged in. Some of these devices may not even need their batteries to operate. The team was able to light a 60W light bulb from a power source...

Multiprocessing system architectures come in all shapes and sizes, so it is dangerous to make any generalizations. But perhaps there's agreement that most systems can be classified as either symmetric multiprocessing (SMP) or asymmetric multiprocessing (AMP).
