Universal Latch Sensor for enhanced security

Southco's Universal Latch Sensor (ULS) is a simple magnet that attaches to an existing latch, and a magnetic sensor that attaches to the inside of an existing door frame. When the door is closed and the latch is engaged, the magnet comes into proximity with the sensor, sending an electronic signal to your security system. This lets you know the door is closed and the latch is secure. The signal from the ULS can be used in a variety of ways, from integrating security systems to turning on existing lights inside an enclosure. Southco also offers a sensor with built-in LEDs that automatically illuminate when the latch is opened.

Ultrasonic leak detector for energy conservation

EXAIR's Ultrasonic Leak Detector (ULD), a hand-held instrument engineered to help locate the source of costly leaks in a compressed air system, has received an upgrade in look and function. Up to 30% of the compressed air generated in industrial plants is wasted through leaks that go undetected. The EXAIR ULD can play a major role to identify and pinpoint these costly leaks, allowing quick repair and cost savings. Testing the various unions, pipes, valves and fittings of a complete installation can be done quickly and effectively at distances up to 20 ft (6.1 m) away.

What can you do with touchless magnetic angle sensors?

Novotechnik has put together a really informative video highlighting real-world applications for their RFC, RFE, and RSA Series touchless magnetic angle sensors. You may be surprised at the variety of off-highway, marine, material handling, and industrial uses. You'll learn how they work (using a Hall effect microprocessor to detect position) and their key advantages, including eliminated wear and tear on these non-mechanical components. We love when manufacturers provide such useful examples.

Raytheon's aircraft warning system will alert pilots to cyber attacks

How can an airplane be hacked? The answer, say experts, may be to confuse the pilot.

"Taking control over an airplane isn't as easy as flying a drone; an attack is more likely going to be simulating malfunctions so a pilot loses trust in his or her aircraft," says Mike Worden, a Raytheon engineering fellow and the company's principal investigator for cyber hardening projects.

Raytheon is working on a company-funded research and development project to provide commercial and military pilots with a cyber-attack warning system within the next year. The company is developing two products: a software-only technology and a hardware-deployable module. Software will provide a quick-and-easy fix should the need arise, while the hardware is designed to give airlines and the military a resilient, persistent solution for aircraft cyber protection.

"Think of it as the cyber equivalent of a missile warning system," Worden says. "When an enemy missile locks onto an aircraft, the pilot gets alerted so he or she can take evasive action, popping off flares and chaff to avoid getting shot down. With a cyber warning system, pilots will also be able to tell if anything on the aircraft has been hacked and performing actions that it shouldn't."

Worden has assembled a team of cyber vulnerability experts and engineers led by Greg Ladd, an engineering fellow and cyber mitigation principal investigator, to prevent the five Ds of non-kinetic warfare: denial, disruption, degradation, destruction, and deception.

"The team has developed software that looks for anomalies on the aircraft buses -- the communication systems that control, monitor, and transfer data between different electronic components in the aircraft -- and remote terminals, which could be any device connected to the buses, such as annunciators, flaps, lights, and landing gear," Ladd says.

Those current systems are often based on 1970s technology, according to Worden, designed before the need for cyber defenses.

"In today's Internet of Things, we think about cyber threats a lot," he says. "The consequences of a compromised aircraft could be catastrophic."

According to Worden, the greatest cyber security threat facing aircraft is introduction of malware through the supply chain, since aircraft parts are manufactured all over the world.

"Malicious code could remain dormant until specific conditions are met before it's triggered, such as, for example, reaching an altitude of 10,000 feet on its 30th flight," Worden said. "Talk like this gets pilots hyperventilating, and I can tell you I get a little more nervous when I hit turbulence these days."

Worden says that a single compromised component or "bad actor" could take advantage of the entire system. The exploit could deceive the pilot into thinking the aircraft was doing something that it shouldn't, such as losing fuel or having an engine fire, or it could actually take control of it remotely.

The cyber warning system would detect if a component aboard is "misbehaving" or suddenly appears when it shouldn't an issue alert.

During military operations, a cyber attack on an aircraft could trick pilots into not trusting their instruments and aircraft. If they don't trust their aircraft, then their mission fails.

"Today, our system lets pilots know of cyber intrusions, allowing them time to react and switch over to alternate systems," Ladd says. "It lets them know, 'My engine really isn't on fire; it's a cyber issue.'"

Both Worden and Ladd say that the Oct. 2016 distributed denial of service cyber attacks against the internet provider Dyn, which blocked major websites from users across Europe and North America, annoyed and inconvenienced many across the globe, but they weren't life threatening.

"Nobody died during the recent DDOS attacks -- at worst, you weren't able to stream a movie or post where you ate dinner that night," Worden says. "A denial-of-service attack on aircraft could quickly turn into a tragedy. The pilot needs to be notified, because immediate action is warranted. That's the scenario that we're looking to protect against."
