Thinking Outside of the Box: Optimizing System Design With Embedded Expertise

Increasing technical requirements and tighter budgets provide challenges to integrators designing optimal system solutions for SWaP-constrained spaces. Dialoguing with highly knowledgeable COTS vendors early in the design process provides integrators with alternative systems engineering perspectives that result not only in better SWaP-optimized solutions, but reduced cost and schedule times. As a leading COTS vendor, Curtiss-Wright is exposed to a myriad of design problems every day, and has unmatched expertise in properly addressing constraints and providing innovative approaches to any design issue. Allowing our COTS hardware experts to mitigate SWaP-constraints early on in the embedded system design process results in highly-optimized re-architected solutions, and eliminates cost, weight, and schedule penalties.

Expanding GNSS Testing with Multiple Synchronized Signal Recorders

In order to greatly expand recording bandwidth, you can deploy multiple tightly synchronized recorders in the field. Averna studied the example of two RP-5300 recorders (2x50 MHz channels each) that were synchronously inter-connected to form a virtual recorder with total bandwidth of 200 MHz.

Eliminate Risk of Contention and Data Corruption in RS-485 Communications

The RS-485 communications standard was introduced in 1983 by the Electronic Industries Alliance (EIA) as a two-wire, half-duplex, multi-drop alternative to the point-to-point RS-232 interface. (Note: RS-485 can also be wired using 4-wires to enable full-duplex communication). RS-485 uses differential signaling to allow up to 32 devices to communicate peer-to-peer at distances up to 4000 feet. In most RS-485 configurations two signals, a positive and a negative, are run as a twisted pair. Since these signals are compared to one another rather than a ground reference like RS-232, RS-485 communication is less susceptible to external noise injected on the wiring and performs more reliably in industrial environments.

Performance Characteristics of Digital Frequency Discriminators

Digital frequency discriminators are key components of instantaneous frequency measurement (IFM) receiver systems as well as many other complex electronic warfare (EW) systems. However, to obtain optimum results it is essential to match DFD performance levels to a specific application. DFDs are integral components of IFM receiver systems; they may also be imbedded into a wide range of military systems such as radar warning receivers (RWRs), electronic countermeasures (ECM) systems, and electronic support measures (ESM) platforms, where they help provide instantaneous frequency measurement capability.

Connectors Outperform Hardwiring for Manufacturers and Their Customers

Many thousands of equipment manufacturers have switched from point-to-point (hard) wiring to connector-based cable assemblies in factory and process automation and control systems. Adopting progressive connectivity solutions has improved their unit costs and productivity. It allows them to turn around orders and complete installations much faster. With margins under increasing pressure, many OEMs have come to regard these benefits as a must-have. For many of their customers, the principal argument for connector-based wiring over hardwiring – a lower total cost of ownership over the service life of the machine – is equally compelling.

Powering Wearable Technology and the Internet of Everything

How are the billions of new wearable technology devices and Internet of Everything sensors going to be powered? We do not want to have billions of toxic Primary batteries in our landfills. These new intelligent devices will need to harvest surrounding ambient energy for life-of-product powering. This White Paper describes how new system architectures, energy harvesting technologies and safe rechargeable solid state batteries can be used to create high-efficiency energy harvesting-based systems.

Electronics Subracks: Requirements, Selection Criteria And Options For Adaptation

When selecting an electronics subrack, it is important to consider several factors, including application requirements and environmental conditions. Flexible product platforms, such as modular subracks, enable diverse configurations for various dimensions, static and dynamic loading levels such as shock and vibration resistance, electromagnetic interference shielding and individual internal mounting options.
