This paper details a proposed system for burning in sorted die. The system described allows sorted diced die to be electrically stressed at high temperatures for a typical burn-in cycle. Furthermore the system allows the die to be re-screened after the burn-in cycle is completed.

Content Addressable Memories (CAMs) allow considerably finer-grained parallelism than conventional shared or distributed memory multi-processors. This fine-grained "Processor-In-Memory" concept can be employed to a large degree during Semantic Network processing in support of Artificial Intelligence (AI) with specific applications in speech and natural language processing. A special-purpose CAM configuration is presented based on requirements for a nominally-sized 64 K node semantic network with 8 bit-markers and 32 relationship types. Analysis for a target application shows that the extensive use of parallel Marker-Propagation and Set Theoretic Operations yields approximately 30-fold speedup over systems with standard Random Access Memories.

This paper describes the analysis, design and simulation of the series-parallel resonant converter under various load conditions. The converter's operation is described in detail. Also, the control characteristic curves are shown, from which the design procedure is developed. A specific design example with PSPICE simulation results is presented for the proposed topology. Finally, the simulated results are compared to the theoretical ones.

This paper describes some scalable photonic switch architectures based on passive star couplers and wavelength-division multiplexing. The development of these architectures is motivated by several implications to the use of passive photonics: low access latency, large switching capacity, improved fault tolerance, and bandwidth/spatial reconfiguration. Due to crosstalk and power budget factors, the number of separable wavelength channels with direct detection devices is limited. Scalability in the described architectures is achieved by efficiently combining wavelength and space division, using multiple star couplers. Two approaches are presented, both feature conflict-free communication: multi-access based on interleaved time-division multiple-access and virtual point-to-point based on multi-hop lightwave shuffle networks. Results concerning realization, delay-throughput performance, and wavelength assignment are summarized.

We propose a preliminary mathematical model and simulation of temporally and spatially patterned alternation of postsynaptic depolarization sites as a hypothetical function of structural changes in the target neuron biomembrane. Our model demonstrates that observed state changes in a target neuron are not only a function of phase relationships among excitatory and inhibitory inputs but of where within the cell the last action potential was initiated. Neurobiological evidence indicates that the observed changes may be a function of altered molecular positions and orientation within the target membrane lattice. We conclude with a brief discussion of the possible role of the system in the regulation of electrical signals.

The software program called STADIUM has been developed by researchers at Florida Institute of Technology (Florida Tech) through funding from SEMATECH. The purpose of STADIUM is to facilitate the statistical design and simulation of integrated circuit processes, devices and products. It is a software shell which uses existing simulators in a design of experiments statistical methodology and allows the estimation of the statistical response of the manufacturing environment. This paper presents some of the methodology and implementation details of STADIUM.

For years people have been in love with the automobile. Some people just enjoy using the automobile as transportation while others also enjoy the workings and operation of this fascinating machine. The automobile is not without as problems of pollution and energy consumption. These problems are changing its design and construction. New clean energy sources are being analyzed and applied to power the modern automobile. A space age energy source now being considered by some and used by others to power the automobile is photovoltaics. Photovoltaics (PV) is the direct conversion of sunlight to electricity. There are a number of devices in the modern car that are electrically powered. PV could provide a clean endless supply of electricity for air conditioning, radios and other electrical components of a car. Most people have never heard of photovoltaics (PV). There has been a great deal of research in PV among energy experts. The automobile is known the world over in both use and operation. The author describes how the merging of these two technologies will benefit mankind and without damaging the environment.

EMI and EMC testing of very large integrated systems such as aircraft and helicopters can be accomplished in large anechoic chambers. There are now several very large anechoic chambers in existence. However, all anechoic chambers have inherent limitations. These limitations include size, safety, and numerous other technical issues. For items larger than an anechoic chamber or for a test requiring the exercise of aircraft engines or rotating helicopter blades, outdoor testing in a virtual anechoic chamber is a viable solution for meeting EMI and EMC test objectives. This paper presents a site feasibility analysis for an open air virtual anechoic chamber for EMI and EMC test capability. To illustrate the analysis, the example selected is the site at the Preflight Integration of Munitions and Electronics Systems (PRIMES) Facility located at Eglin Air Force Base, Florida.

The Time Processor Unit is a modular component of the MC68300 and MC68HC16 families of microcontrollers. Both of these families of MCU's are based on modules that can be connected to a common bus. This bus, known as the Intermodule Bus or IMB, serves as the data/address/control bus structure to connect the modules together. The CPU module can communicate with the other modules by reading/writing the control and data registers of a particular module. Some modules have there own local processor or arithmetic logic unit complete with local RAM and ROM. In this case the CPU can communicate with modules of this type through dual-ported RAM. The Time Processor Unit is a module of this type.
