Powerful LED curing lamp for tight work spaces

DELO now offers a compact LED curing lamp for use in industrial applications with limited work space. The powerful DELOLUX 503 is designed to bond small surfaces, like cameras used in autonomous cars, within seconds on serial production lines. The new lamp directs light diagonally downward so that it does not need to be installed at level with the components that need to be bonded. This gives more moving space to axes or grippers and helps to integrate complex systems. The UV lamp ensures high process reliability through continuous intensity control, internal control, and monitoring of important parameters like LED temperature. Up to four LED heads can be controlled by DELO controllers or by an external PLC, allowing the adhesive to be evenly exposed from several angles.

Bend the rules of lighting design: Cut and form LED sheets

VCC is bending the rules of lighting design with its new VentoFlex tiles. The VentoFlex modular lighting system opens up countless ways for architects and lighting designers to make an impact. Available in 12-in. x 12-in. sheets, these innovative LED tiles can be cut and formed around any design element, including rounded corners and tight spaces, without taking up much room at all -- just 0.15 in. (3.81 mm). A pair of scissors is the only tool required to cut VentoFlex tiles to the size and shape you desire. Ten or 15 tiles can be linked together to one driver and dimmer to create thousands of square inches of versatile lighting power! This product is in the running for the 2019 Elektra Awards LED Product of the Year in Europe.

No-wear flat magnetic angle sensors

Novotechnik U.S. has just introduced the Vert-X 05E Series of magnetic rotary position sensors with compact, flat housing. Interfaces include analog, SPI, and incremental. The series is available in single and redundant versions. The sensors are touchless magnetic angle sensors with a permanent magnet that can be secured to an application's rotating shaft, so there is no direct mechanical linkage between the shaft and the measuring system -- and therefore no wear. Key specifications for Vert-X 05E include 5-mm profile, 0 to 360° measurement range, repeatability of 0.1° or better, and maximum hysteresis of 0.1°. Sample rate is up to 5 kHz, and its active measurement region extends to within 6 mm from edge of housing.

Can electrical resistance be used to predict shielding effectiveness?

Conductive elastomer EMI shielding gaskets use metallic particles to create a conductive path and shield enclosures from electromagnetic radiation. Gaskets with silver particles, which are very conductive, often outperform gaskets with graphite particles. However, this is not always the case. A common misconception is that a measurement of DC resistivity can directly predict shielding effectiveness. Ben Nudelman, market development engineer at Parker, explains why.

Researchers create quantum chip 1,000 times smaller than current designs

Researchers at Nanyang Technological University, Singapore (NTU Singapore) have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, but offers the same superior security that quantum technology is known for.

Most leading security standards used in secure communication methods, from withdrawing cash from an ATM to purchasing goods online on a smartphone, do not leverage quantum technology. The electronic transmission of the personal identification number (PIN) or password can be intercepted, posing a security risk.

Roughly 3-mm in size, the tiny chip developed by NTU scientists uses quantum communication algorithms to provide enhanced security compared to existing standards. It does this by integrating passwords within the information that is being delivered, forming a secure "quantum key." After the information is received, it is destroyed along with the key, making it an extremely secure form of communication.

A 3-mm chip developed by NTU scientists uses quantum communication algorithms to provide enhanced security. It needs 1,000 times less space than current quantum communication designs.

 

 

 

 

This chip also needs 1,000 times less space than current quantum communication designs that can be as big as a refrigerator or even take up the space of an entire room or office floor. This opens doors for more secure communication technologies that can be deployed in compact devices such as smartphones, tablets, and smart watches. It also lays the foundation for better encryption methods for online transactions and electronic communication.

Led by NTU Professor Liu Ai Qun and Associate Professor Kwek Leong Chuan, the team's findings were published in the leading peer-reviewed journal Nature Photonics.

Kwek explained that quantum communication works by using randomized strings of code to encrypt the information, which can only be opened by the intended recipient with the correct "key." There is no need for additional passwords or biometric data to be transmitted, which is the standard practice in current forms of communication.

"It is like sending a secured letter. Imagine that the person who wrote the letter locked the message in an envelope with its 'key' also inside it," said Kwek. "The recipient needs the same 'key' to open it. Quantum technology ensures that the key distribution is secure, preventing any tampering to the 'key.'"

Military-grade communication tech -- made in a cost-effective manner
The world's biggest tech companies such as Google and IBM are racing to develop quantum supercomputers that aim to revolutionize computing at speeds now inconceivable.

One highly anticipated strength of quantum technology lies in cryptography, the art of secret communication.

With the proliferation of Internet services, emails and messaging platforms such as WhatsApp, Facebook, Skype, Snapchat, and Telegram have created their own secured channels for communication -- what are known as "classical channels."

In contrast, "quantum channels" that carry information have security protocols that are integrated into the encrypted data. Each channel is uniquely different from any other, reducing or even eliminating the risk of information being intercepted or leaked during transmission.

Simply put, quantum technology does not require additional transmissions of passwords or biometric data that is necessary in "classical channels." This eliminates the risk of interception or information being leaked, creating an almost unbreakable encryption.

The quantum communication chip developed by the NTU researchers will be cost effective, because it uses standard industry materials such as silicon, which also makes it easy to manufacture.

"This is the future of communication security, and our research brings us closer to quantum computing and communication," said Liu. "It will help spark the creation of next-generation communication devices, as well as enhance digital services such as online financial portals of banks, and digital government services."

The NTU team is now looking to develop a hybrid network of traditional optical communication systems and quantum communication systems. This will improve the compatibility of quantum technologies that can be used in a wider range of applications such as internet connectivity.
