Developing Smart and Affordable Intelligence, Surveillance and Reconnaissance Technologies: Five Trends to Watch

The demand for intelligence, surveillance and reconnaissance (ISR) technology and infrastructure is growing significantly. For example, in the 10 years from 2002 to 2011, U.S. Defense spending on ISR grew by a factor of six, compared with relatively flat defense spending overall [House Permanent Select Committee on Intelligence, 2012]. Similar patterns of spending can be seen around the globe. Simulation-based engineering has long played a role in advancing ISR technology development — from unmanned systems to antennas to systems and embedded software. The value proposition has long been proven.

Synthetic Sapphire: Extreme Performer

Sapphire, the single crystal form of alumina (Al2O3), was first synthesized more than a century ago, but the most exciting advances associated with this versatile material are taking place today. Shaped by the dual forces of application demands and technological advances in the fabrication and finishing process, synthetic sapphire is often the material of choice for design engineers dealing with extreme conditions of high temperature, high pressure and harsh chemical environments.

The Basics Of Pressure Regulators

Pressure regulators are found in many common home and industrial applications. For example, pressure regulators are used in gas grills to regulate propane pressure, in home furnaces to regulate natural gas, in medical/dental equipment regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel pressure, and in fuel cells to regulate hydrogen. Although the applications vary considerably, the pressure regulators provide the same function. Pressure regulators reduce a supply pressure to a lower outlet pressure and they maintain this outlet pressure regardless of inlet pressure fluctuations. This reduction in pressure is the key characteristic of pressure regulators; outlet pressure is always at a pressure below the inlet pressure.

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.

The True Cost of Bearing Lubrication

Today, machine and equipment manufacturers are feeling more pressure than ever to reduce costs without sacrificing machine performance and this balancing act can be difficult to achieve. Original equipment manufacturers (OEMs) often overlook a simple solution that can have a positive, long-term impact on profitability for themselves and their customers: the elimination of bearing lubricant. By eliminating lubrication systems where possible, OEMs can reduce production costs, while at the same time making their equipment more marketable and less expensive to operate for the end users.

Avionics Reliability – Thermal Design Considerations

Thermal design for reliability faces challenges from power dissipation demands from increased processing, sensing and communication requirements plus targets for size, weight and operation. Address thermal challenges effectively with electronics cooling simulation that brings electronic and mechanical design flows closer.

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.
