LED Driver Boards

Two new Smart ForceTM LED driver boards from Endicott Research Group (Endicott, NY) provide wide range dimming, wide input voltage, and full brightness. The SFDL Series driver board provides high efficiency power with a maximum current of 180 mA, and measures 1.10 in. by 3.93 in. The SFDC Series driver board is a full-function LED driver with a maximum current of 1000 mA. It measures 1.10 in. by 5.61 in. and provides an on-board PWM dimming ratio of 1000:1 and external PWM dimming to a ratio of 20,000:1. Both drivers can be used with OEM panels’ existing LED backlights or with ERG’s Smart Force LED rails.

Digital Panel Meters

Mouser Electronics, Inc. (Mansfield, TX) has expanded its C&D Technologies portfolio to include the DMS-30DR series daylight-readable digital panel meters. The DMS-30DR series of large, 0.56-inch high, super-bright red LEDs are readable in direct sunlight without the need for special filters or shading devices. These devices can be used in very high ambient light conditions, but can also dim themselves for poorer light. Characters on the DMS-30DR series can be read at viewing angles of up to 180° in both vertical and horizontal planes.

CO2 Lasers

A new series of low-power, continuous-wave (CW) CO2 lasers from Coherent, Inc. (Santa Clara, CA) now offers high reliability operation for OEM applications. The new DIAMOND C Series consists of sealed lasers with output powers of 30, 40, 55, and 70 watts at 10.6 μm. The lasers offer amplitude stability of ±5% for air-cooled models and ±3% for liquid-cooled units. The DIAMOND C Series also offers output beam characteristics of M2 < 1.2 for 30W and 55W systems, and M2 1.3 for 40W and 70W models.

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?
