Identifying and Isolating Signals Using Radio Frequency Photonics

A single antenna can be used for both transmission and reception. To accomplish this, the transmission must be isolated from the reception. In Figure 1, a radio frequency (RF) circulator is connected right after the antenna. The three-port device separates the transmit path from the receive path. After the circulator, a system can be used to identify the frequency of different signals. Once the frequency has been found, a filter with the right pass-band frequency can be used to isolate signals from each other.

High-Reliability Capacitors

Maintaining technological superiority remains critical for national defense forces. Many face informal adversaries that are adept at harnessing today’s sophisticated civilian technologies, like mobiles, M2M communication and social media, to launch attacks unexpectedly. Defense operations are intelligence-led; responses must be surgical and precision-guided to avoid harming civilians; and every measure must be taken to avoid injury to soldiers or loss of equipment. At the same time, government funding of defense forces, particularly in the West, is under pressure.

WIAMan

The newest crash test dummy in development is actually a blast test dummy. WIAMan (Warrior Injury Assessment Manikin) is a ground-breaking anthropomorphic test device (ATD) being developed by the U.S. Army. It’s the first test dummy designed specifically for vertical loading in under-body blast (UBB) scenarios, like the ones soldiers may experience in combat from IEDs. A key goal of the program is to develop a scientifically-valid injury criteria for blast testing of military ground vehicles. This test data will be the most advanced of its kind and will be used to develop new, safer vehicles and associated equipment to help reduce injury risk for warfighters. Another first coming out of this program is the high-tech data acquisition system that is entirely contained within the dummy, making it the first completely autonomous device of its kind.

Forward observers, experts in directing artillery and mortar fire onto enemy targets, have been testing a new piece of targeting equipment recently. “Black Falcon” soldiers of Headquarters and Headquarters Battery, 2nd Battalion, 319th Field Artillery Regiment, put their hands on the Joint Effects Targeting System (JETS) — a modular, man-portable, hand-held, day/night, all-weather, target observation, location, and designation system. Components of the JETS include a Handheld Target Location Module (HTLM); a Laser Marker Module (LMM); and a Precision Azimuth Vertical Angle Module, all mounted atop a tripod.

High Temperature Graphene-Peek Adhesive

Joining of composites can be a challenging issue. If adhesives are used, the joints are permanent and cannot be undone. If they need to be undone, inserts are often used and these inserts increase cost and weight. Additionally, fibers can be cut in the process leading to a part with weakened mechanical properties.
