Battery Family Serves UAV Power Back-Up Needs
UAVs need reliable back-up power in the event of catastrophic main engine failures. They require battery packs to power the UAV’s recovery system that enables navigation and control systems to continue operating so the damaged craft can glide to a safe landing away from enemy territory. The power management solution must deliver high energy density and capacity while also offering the ability to withstand extreme environments. Reduced battery size and weight leave more room for the payload of sensors, cameras, communications equipment and so on. With all that in mind, Tadiran offers its TLM Series of high-power lithium batteries that are suited to serve as the battery packs that power emergency recovery systems on UAVs.
The TLM-1550HP high-power lithium AA-size batteries deliver 2W-hours of energy with an open circuit voltage of 4.0V and are capable of handling pulses of up to 15A, and 5A maximum continuous current at 3.2V. The batteries can be easily combined in series or parallel to create custom battery packs in virtually any shape or size. Smaller cells, including sub-1/2 AA and 2/3 AA sizes, are also available. TLM-1550HP cells provide up to 20 years of service life, and can be periodically tested, enabling system readiness to be confirmed without fully discharging the battery. These cells are safe, rugged, and capable of withstanding extreme temperatures from -40° to +85°C. The cells feature fast activation, with instantaneous voltage after prolonged storage. Moreover, no squibs are needed to start the battery and they require no thermal insulation.
Unlike reserve and thermal batteries, TLM-1550HP cells do not generate excessive amounts of heat, which saves space and reduces weight by minimizing mechanical and thermal design considerations. The cells feature a glass-to-metal hermetical seal instead of a crimped elastomer gasket. Aside from UAV applications, TLM-1550HP cells are also found in other military and aerospace applications, including rockets and missiles, smart ammunition, mines, jammers, unattended ground sensors, sonobuoys, listening devices, weapon sights, artillery fuses, trajectory correction add-on kits, proximity fuses for bombs, aircraft ejector seats, and in sensors for dispersed munitions.

Software Radio PMC Offers Beamforming, Power Meter
Real-time software radio, beamforming, signal-intelligence and radar systems all have something in common. They’re all hungry for an integrated solution–and that solution does conversion, processing and beamforming all the better. Pentek does exactly that with its Model 7152, a quad 200 MHz, 16-bit A/D digitizer with a 32-channel digital down converter (DDC) configured in a PMC format. The 7152 features 32 power meters that continuously measure the individual average power output of each of the 32 DDC channels. In addition, 32 threshold detectors automatically send an interrupt to the processor if the average power level of any DDC falls below or exceeds a programmable threshold.
The built-in power meters and threshold detectors offload these tasks from a downstream processor and present average power measurements for each channel in easy-to-read registers. A second set of new features makes the module ideal for beamforming applications. By adjusting the phase offset and weighting of the individual channels, followed by summation, the antenna can be “steered,” rotating the azimuth angle to enhance receptivity in a particular direction. The 7152 PMC module is also available in a variety of additional form factors. The 7152 PMC module is priced at $14,500 for the hardware.

Trace Technology Shrinks Resistor Power, Footprint
Shrinking size, weight and power has become a top priority in a variety of military system designs. Attacking that issue at the board trace level, Ohmega Technologies has introduced its OhmegaPly Orbit product, a 10 ohm per square sheet resistivity thin film material. Orbit allows termination resistors to be built within traces and eliminates the requirement for designing a resistor footprint and placing them within the circuit layout. Orbit resistors can be placed on any circuit layer of a multilayer printed circuit board, but is especially suited for internal circuit layers. Orbit provides smaller resistor footprints and tighter finished resistor tolerances.
Orbit is processed like the other OhmegaPly products using conventional subtractive printed circuit equipment and techniques. Since the resistors are built within the trace, any board shop with the capability of building controlled impedance traces can build Orbit resistors. Orbit is offered at a 3 percent material tolerance. This allows finished resistor tolerances of 5-10 percent. This is critical since the ability to trim resistor elements of 5 mils and smaller widths becomes problematic. Orbit also has higher power dissipation than higher sheet resistivity products with power dissipation over 25 percent greater than OhmegaPly 25 ohm per square product. This is also crucial for the formation of very small resistor elements that can handle the rated power requirements.

Tool Enables Reliable Real-Time Messaging
Lossy networks–those that have uncertain or sporadic connectivity–are common in a variety of applications, such as defense and unmanned vehicles. There is support for lossy networks in the RTI Data Distribution Service 4.3 rev from Real-Time Innovations. Most distributed systems today rely on messaging middleware that uses the Transmission Control Protocol (TCP) for inter-application and inter-node communication. TCP has characteristics that make it undesirable for use in real-time applications where the underlying network itself is not reliable. RTI provides a built-in transport that is Internet Protocol (IP)-based and employs the User Datagram Protocol (UDP). RTI also provides a completely tunable reliability model to optimize transport utilization over transient, high-delay, bandwidth-limited and lossy networks.
One of the many ways the RTI reliability model provides higher utilization of low bandwidth networks is that it allows the frequency of heartbeats and acknowledgements to be fine-tuned. The RTI reliability model is completely configurable, enabling developers to achieve the appropriate balance of determinism and reliability even in the presence of bandwidth-limited, high-latency and lossy transports. The use of UDP in conjunction with the RTI reliability model supports features not available with TCP, such as multicast, for extremely efficient data distribution.
