Emerging Power and Energy Technologies for Portable Electronics

A report discusses data obtained for the Navy's Special Operations Command (SOCOM), which seeks a portable power/energy source capable of providing sufficient power and energy for complex missions at a minimal weight penalty. The report focuses on the specific energy of systems, defining the weight of the power/energy system that must be carried by the soldier.

Reduced Power Laser Designation Systems

This work contributes to the Micropulse Laser Designation (MPLD) project to develop a six-pound eye-safe micro-pulse laser system to locate, identify, range, mark, and designate stationary and moving targets. MPLD uses laser pulses of much lower energy and higher repetition rates than in existing laser designation systems. Because of this, MPLD presents a range of new circuit design and signal processing problems.

Continuous-Wave Laser Diodes Based on a Novel InGaAsNSb Material System

Laser sources operating in the spectral region from 2 to 3.5 μm are in demand for ultra-sensitive laser spectroscopy, medical diagnostics, home security, industrial process monitoring, infrared countermeasures, and optical wireless communications. Currently, solid-state lasers and optical parametric oscillators and amplifiers are used as coherent light sources in this spectral region.

Photon Counting Chirped Amplitude Modulation Ladar

This work is a follow-up to prior efforts to develop a method using Geiger-mode avalanche photodiode (GM-APD) photon counting detectors in chirped amplitude modulation (AM) ladar receivers to yield sensitivities approaching the shot noise limit. Such sensitivities represent about four orders of magnitude improvement over the sensitivities of the currently used unity-gain, opto- electronic mixing (OEM) metal-semiconductor-metal (MSM) detectors. These sensitivity improvements may enable compact, low-power, eye-safe, and/or long-range ladar with low-cost, low-bandwidth readout integrated circuits for foliage and camouflage penetration, target ID, manned and unmanned ground and air vehicle navigation, 3D face recognition, battle damage assessment, and change detection.

VME NAS RAID Blade

ACT/Technico (Warminster, PA) now offers the VME RAIDStor, a single-slot 6U network attached storage (NAS) blade that provides the same automatic, transparent data replication and re-sync of traditional box-level RAID storage modules in a more compact footprint. With network access for up to 18 slots (up to 1/2 terabyte per slot) in a 19" chassis, the SATA-based VME RAIDStor is suitable for use throughout many industries in a number of high availability, data intensive applications including message processing, network- centric military environments, redundant self-hosted Web servers or storage repositories, as well as transaction processing and logging.

Network Analysis Software

OMICRON Lab (Houston, TX) has released new operation software for its Bode 100 portable network analyzer, giving users access to an extended frequency range. With the release of Bode Analyzer Suite V2.2, OMICRON Lab has managed to reduce the lower frequency border down to 1 Hz, giving the Bode 100 a range of 1 Hz – 40 MHz for Gain/Phase and impedance measurements. This extended frequency range makes the Bode 100 suitable not only for classical network analysis but also for the analysis of control circuits (e.g. DC/DC Converters), audio and ultrasound measurements, and the measurement of piezoelectric sensors and transducers. Other features of the new operation software include a straightforward and intuitive graphical user interface and OLE compatible automation interface, which facilitates integration of the Bode 100 into automated measurement setups for a variety of manufacturing or quality control applications.

Compact Embedded Computer

Mercury Computer Systems (Chelmsford, MA) has introduced the PowerBlock™ 50 system, a high-performance, ultra-compact embedded computer. The system's modular architecture allows for flexible configurations of multiple processors, delivering well over 100 GFLOPS of processing power in a small, lightweight package. A fully configured PowerBlock 50 weighs less than 10 pounds and measures approximately 4" × 5" × 6". The system is available now as the PowerBlock 50 EDK (Engineering Development Kit), which is a complete software development platform. The EDK includes a PowerBlock 50 system, Linux BSP development environment, and a desktop heat rejection unit (HRU) to support the PowerBlock 50's cooling requirements. The PowerBlock 50 EDK is customizable into configurations that include PowerQUICC™, Virtex™-4, and Intel processors, and SATA storage. Each configuration includes Gigabit Ethernet and RS-232 I/O interfaces.
