Conductive Brush Ring overcomes current leakage in EV powertrains

SKF's new Conductive Brush Ring paves the way to greater reliability and longer life in high-performance electric vehicle powertrain systems. Using pure carbon fiber bristles, it provides a reliable electrical connection between an EV eAxle rotor shaft and its housing. When used in combination with SKF Hybrid ceramic ball bearings, it helps to alleviate parasitic current effects that can lead to premature failure in bearings and other components. Available in different configurations for wet (oil-lubricated) motor designs -- and soon for dry (sealed) applications.

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.

Organizations rush to use generative AI tools -- despite significant security concerns

New research from cloud-security provider Zscaler suggests that organizations are feeling the pressure to rush into generative AI (GenAI) tool usage, despite significant security concerns.

According to its latest survey, "All eyes on securing GenAI," which polled more than 900 global IT decision makers, although 89% of organizations consider GenAI tools like ChatGPT to be a potential security risk, 95% are already using them in some guise within their businesses.

Even more worryingly, 23% of this user group are not monitoring the usage at all, and 33% have yet to implement any additional GenAI-related security measures -- although many say they have it on their roadmap. The situation appears particularly pronounced among smaller-size businesses (500 to 999 employees), where the same number of organizations are using GenAI tools (95%), but as many as 94% recognize the risk of doing so.

"GenAI tools, including ChatGPT and others, hold immense promise for businesses in terms of speed, innovation, and efficiency," said Sanjay Kalra, VP Product Management at Zscaler. "However, with the current ambiguity surrounding their security measures, a mere 39% of organizations perceive their adoption as an opportunity rather than a threat. This not only jeopardizes their business and customer data integrity, but also squanders their tremendous potential."

The survey identified the top five use cases for GenAI:

• Data analysis: 78%
• R&D services development: 55%
• Marketing: 53%
• End-user tasks: 44%
• Logistics: 41%

Top concerns included:

• The potential loss of sensitive data: 43%
• A lack of resources to monitor use: 43%
• A lack of understanding around the benefits/dangers: 41%

The rollout pressure is not coming from where many people might think. Despite mainstream awareness, it is not employees who appear to be the driving force behind current interest and usage -- only 5% of respondents said it stemmed from employees. Instead, 59% said usage was being driven by IT teams directly.

"The fact that IT teams are at the helm should offer a sense of reassurance to business leaders," Kalra said. "It signifies that the leadership team has the authority to strategically temper the pace of GenAI adoption and establish a firm hold on its security measures, before its prevalence within their organization advances any further. However, it's essential to recognize that the window for achieving secure governance is rapidly diminishing."

With 51% of respondents anticipating a significant increase in the interest of GenAI tools before the end of the year, organizations need to act quickly to close the gap between use and security.

Zscaler provided a few steps business leaders can take to ensure GenAI use in their organization is properly secured:

• Implement a holistic zero-trust architecture to authorize only approved AI applications and users.
• Conduct thorough security risk assessments for new AI applications to clearly understand and respond to vulnerabilities.
• Establish a comprehensive logging system for tracking all AI prompts and responses.
• Enable zero-trust-powered Data Loss Prevention (DLP) measures for all AI activities to safeguard against data exfiltration.

Methodology: In October 2023, Zscaler commissioned Sapio Research to conduct a survey of 901 IT decision makers (ITDMs) across 10 markets [Australia & New Zealand, France, Germany, India, Italy, Netherlands, Singapore, Spain, UK & Ireland, and USA]. These ITDMs work at companies of 500+ employees and across industries.
