High-temp cabinet cooler keeps incineration process in business

An EXAIR client company handles waste treatment on a large ship by operating an incinerator. The area where the incinerator is located gets very hot (over 120° F). This causes failures in the electronics package used to control the incineration process. Since compressed air is readily available, EXAIR's Model HT4225 Cabinet Cooler System is being used to keep the panel cool. It saved the customer from having to replace their control units due to the hot conditions in the incinerator room. Thermostat control is also available, conserving air and operating only when needed to minimize air consumption.

Seifert thermoelectric coolers from AutomationDirect

Automation-Direct has added new high-quality and efficient stainless steel Seifert 340 BTU/H thermoelectric coolers with 120-V and 230-V power options. Thermoelectric coolers from Seifert use the Peltier Effect to create a temperature difference between the internal and ambient heat sinks, making internal air cooler while dissipating heat into the external environment. Fans assist the convective heat transfer from the heat sinks, which are optimized for maximum flow.

EMI shielding honeycomb air vent panel design

Learn from the engineering experts at Parker how honeycomb air vent panels are used to help cool electronics with airflow while maintaining electromagnetic interference (EMI) shielding. Topics include: design features, cell size and thickness, platings and coatings, and a stacked design called OMNI CELL construction. These vents can be incorporated into enclosures where EMI radiation and susceptibility is a concern or where heat dissipation is necessary. Lots of good info.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Top 5 reasons for solder joint failure

Solder joint reliability is often a pain point in the design of an electronic system. According to Tyler Ferris at ANSYS, a wide variety of factors affect joint reliability, and any one of them can drastically reduce joint lifetime. Properly identifying and mitigating potential causes during the design and manufacturing process can prevent costly and difficult-to-solve problems later in a product lifecycle.

Marines put augmented reality system to the test with live-fire testing

A Marine is fitted with the Augmented Immersive Team Trainer (AITT) from the Office of Naval Research (ONR) during ongoing testing at Quantico, VA. The AITT allows Marines to transform any location into a dynamic training ground by injecting virtual images, indirect fire effects, aircraft, vehicles, simulated people, etc. onto a real-world view of one's surroundings.

Marines enrolled in the Infantry Officer Course were able to use Office of Naval Research (ONR)-developed augmented reality technology for the first time as part of live-fire training exercises at the end of the summer this year.

The Marines, as part of the Infantry Officer Course, had the opportunity to try out ONR's Augmented Immersive Team Trainer (AITT) system Aug. 5-6 at a test range on the southern edge of Marine Corps Base Quantico in Virginia.

The AITT system -- which is comprised of a laptop, software, battery pack, and a helmet-mounted display -- can support a wide array of live, virtual, and cutting-edge training scenarios. It uses augmented reality, which means that virtual objects are superimposed onto a real environment, like the yellow first-down lines added to television broadcasts of football games for the benefit of viewers at home. This differs from virtual reality, which is a wholly computer-generated environment in which users immerse themselves.

"This affordable lightweight system can be taken anywhere -- turning any environment into a training ground -- and could be used to prepare Marines for real-world situations and environments they will face," said Brig. Gen. Julian Alford, vice chief of naval research and commanding general of the Marine Corps Warfighting Laboratory.

The field portion of the "call-for-fire" training included aircraft and munitions, which are costly and time-consuming to set up, staff, and equip, but are an important part of the training experience for the student officers. The wait time for a test range can be six to 12 months, rain can cancel the testing, and it can be difficult to get assets in place, since equipment can break down.

The AITT completely bypasses these challenges by using virtual ground vehicles, aircraft, and munitions.

"The system makes the training easier and eliminates the maintenance issues or weather-related restrictions that can pare down or cancel training," said Maj. George Flynn, director of the Infantry Officer Course. "For instance, this system can use virtual air support, so even if it's raining, the students can still be training, getting confidence, and learning the points of employing aviation assets."

The system will enable the student officers to use virtual assets to complement live training or to get additional practice repetitions without having to use live assets, said Dr. Peter Squire, a program officer with ONR's Expeditionary Maneuver Warfare and Combating Terrorism Department who's leading the AITT effort. "And instead of using your imagination, now you can see virtual effects from the blasts, like smoke."

Flynn emphasized that seeing virtual effects makes it much easier for the student to picture the situation. "Rather than having the instructor paint a picture to the student without anything happening, now the student can get a visual of the aircraft they've been controlling in support of a maneuver on the deck," he said.

Flynn envisions more potential uses for AITT in the future: "For example, as part of a company training event, a rifle platoon could be conducting a live-fire attack on a range at the Marine Corps Air Ground Combat Center, while the Fire Support Team could be on the hill practicing employing fires in support of maneuver, using virtual effects."

The AITT program, part of the ONR Capable Manpower Future Naval Capability, wrapped up its fifth and final year with another large-scale demonstration at Quantico at the end of October. Pending the results of a Marine Corps assessment, the program will transition to the Marine Corps Program Manager for Training Systems for further testing and development.
