Tips for Selecting or Designing a Membrane Switch

Membrane switches are known for standing up to tough environmental conditions. Flexible and durable, the membrane switch can be customized with embossing, backlighting, sealing, and electrostatic discharge (ESD) shielding. Membrane switches can be made with either tactile or non-tactile feedback and they can be integrated with LEDs and other components. To get the switch that works for your application, follow these simple guidelines.

Pursuing Agile Signals in a Crowded Spectral Environment

For the capable RF engineer, continuous- wave (CW) and predictably repeating signals are no great challenge. However, design and troubleshooting become difficult when dealing with agile signals, and the challenges grow when these signals exist in an environment densely populated with similarly agile signals. Examples include applications such as radar, electronic warfare, wireless connectivity, and wireless communications. Indeed, some engineering jobs must be performed where two or more of these technologies intersect — sometimes accidentally and sometimes deliberately.

Missile Defense System Signal Processor

The Aegis Ballistic Missile Defense (BMD) system’s recently upgraded signal processor, designed and developed by Mercury Systems, enables the U.S. Navy to defeat more sophisticated ballistic missile threats and improve target identification capabilities. The technology includes an open architecture BMD computing suite that supports future insertion of off-the-shelf products and third-party components. Mercury’s application-ready subsystems (ARS) are integrated as core technologies in the second-generation Aegis BMD system.

Geomagnetic Motion Tracking Products

Any compass incorporated into a host system requires calibration so that the compass properly compensates for ferrous and magnetic components. If this is not done correctly, heading readings can be very inaccurate.
