Electronics & Software

DfR Solutions (College Park, MD) has launched Sherlock automated design analysis software for analyzing, grading, and certifying the expected reliability of products at the circuit card assembly level. The software's intuitive commands and ease of use enable usage among a broad range of engineers and managers,...

Synopsys, Inc. (Mountain View, CA) has introduced DC Explorer, the latest addition to the Galaxy™ Implementation platform, to speed up development of high-quality design data. DC Explorer delivers 5X faster runtime and 10 percent timing and area correlation to DC Ultra™ RTL Synthesis. It also tolerates incomplete design...

A grid-tied photovoltaic (PV) power system is connected directly to the utility distribution grid. Facility power can be obtained from the utility system as normal. The PV system is synchronized with the utility system to provide power for the facility, and excess power is provided to the utility.

There is a great need for oxygen microsensors for aerospace and commercial applications. Current bulk or thick-film solid electrolyte oxygen sensors have the disadvantages of being large in size, high in power consumption, difficult to batch-fabricate, and high in cost.

Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five...

A small microprocessor, suitable for use in applications in which high reliability is required, was designed to be implemented in either an application-specific integrated circuit (ASIC) or a field-programmable gate array (FPGA). The design is based on commercial microprocessor architecture,...

A circuit topography is used to create usable, digital logic gates using N (negatively doped) channel junction field effect transistors (JFETs), load resistors, level shifting resistors, and supply rails whose values are based on the DC parametric...

A technique of monitoring digital closed-loop feedback systems has been conceived. The basic idea is to obtain information on the performances of closed-loop feedback circuits in such systems to aid in the determination of the functionality and integrity of the circuits and of performance margins.

Basis functions were studied and identified that provide efficient and accurate solutions for the induced patch currents and the reflection phase in microstrip reflectarrays. The integral equation of an infinite array of microstrip elements in the form of...
