Oscilloscopes

Agilent Technologies Inc. (Santa Clara, CA) expanded its mixed-signal and digital-storage oscilloscope portfolio with 10 new models that comprise its InfiniiVision 7000 Series. The InfiniiVision 7000 Series offers bandwidths up to 1 GHz and delivers a deep memory waveform update rate of up to 100,000 waveforms per second. Each model is equipped with a 12.1-inch XGA LCD display and comes in a compact package that's just 7 inches deep and weighs 14 pounds. The increased display size helps users who need to display up to 20 channels simultaneously with serial protocol. The update rate is 5,000 times faster than any other available scope, and allows the user to view critical signal detail that other scopes might miss with their longer dead times.

Techniques for Cooling Power and Other Electronic Devices

All electronic devices generate heat due to their unavoidable internal losses and inefficiencies. The higher the efficiency rating of the device, the less internal heat is generated within it. If we could achieve 100% efficiency, and technology is getting ever closer to that elusive goal, no heat would be generated within the device and, therefore, no cooling would be required. Until then, the generated heat must be dissipated to maximize the end product's reliability and prevent its premature failure.

Prototyping PMC Daughterboards

The PMC, or PCI Mezzanine Card, follows the IEEE P1386.1 standard for printed circuit boards. PMCs combine the electrical characteristics of the PCI bus with the mechanical dimensions of the Common Mezzanine Card, or CMC, format. Within the PMC format single PMC boards measure 74mm × 149mm. While the standard also defines a double-sized card, this format is rare. For PMC cards, as defined by the standard, connector configurations can be:

2 bus connectors (P1 and P2) supporting 32-bit PCI signals, 3 bus connectors (P1, P2 and P3) supporting 64 bit PCI signals, and/or 4th bus connector (P4) supporting non-specified I/O signals.

The Virtual Becomes Reality at Iowa State University

The colonel has a problem. He has eight unmanned aerial vehicles (UAVs) flying over the outskirts of Baghdad, looking for potential insurgent activity. Are those people he sees moving through the streets insurgents or are they a US infantry patrol? If he alters the flight path of one UAV to loiter over the suspicious activity, how should he deploy the other seven UAVs to pick up the first's original mission? How does he keep track of the positions of the eight UAVs, what they are seeing, and the locations of nearby US troops, all in real-time?

Data-Based Paradigm for Rapid Development of Advanced Avionics Displays

The database concepts, tools, and runtime software described in this article provide a methodology for creating advanced avionics human-machine interfaces (HMIs), such as those found in modern flat-panel display systems. The key innovation described is the ability to treat the avionics displays as databases rather than as compiled and linked software. This new technology facilitates the goals of open architecture for avionics, a key avionics industry trend.

FPGA-Based Communication Channel for Digital Signal Processor Chips

A method for networking, and a network of, digital signal processors (DSP) via at least one field-programmable gate array (FPGA) enables the simultaneous broadcast of data from a DSP to a number of DSPs. The apparatus comprises a host DSP, at least one FPGA in communication with the host DSP for receiving a digital signal from the host DSP, and at least one non-host DSP in communication with at least one FPGA for receiving the digital signal.

Applying Reconfigurable Computing to Acoustic Sensors Using FPGAs

A novel microsensor processing architecture allows a field-programmable gate array (FPGA) to act as a reprogrammable preprocessor or coprocessor to a general-purpose processor (GPP). The FPGA does most of the computationally complex pieces of the algorithm, while the GPP is lightly loaded, performing control, communications, and housekeeping tasks (Figure 1). The flexible architecture supports a wide range of low-power applications, while still being able to leverage emerging commercial technology.
