The new Hypertac Green Connect contact technology
S
miths Interconnect, a provider of technically differentiated electronic components, subsystems, microwave, optical and radio frequency products, has introduced Hypertac Green Connect, a new lead-free and beryllium-free hyperboloid high-power contact technology, to its high reliability contact technologies for demanding applications.
Aimed at solving the issue of power loss, this solution is designed to ensure the optimal utilisation of every kilowatt-hour of energy stored in the battery, enhancing overall efficiency and performance. Specifically tailored for the battery systems market and related applications, this advanced hyperboloid contact design provides a robust connection capable of efficiently handling continuous currents of up to 500 amperes.
The lower contact
resistance of the Hypertac Green Connect technology reduces heat build-up allowing the contacts to handle greater current in smaller contact assemblies without adversely affecting temperature rise. The technology uses a set of socket wires, properly angled to form a hyperboloid-shaped, elastic and conductive sleeve. When the mating pin enters the socket, the sleeve expands around it, providing many lines of electrical contact with the mating pin, as opposed to a few “high spots” on a conventional contact.
Also, the elimination of beryllium and lead from the Hypertac Green Connect is said to deliver operational and environmental benefits. Both beryllium
and lead require significant substance compliance management. Certifications of compliance, declarations of meeting threshold limits, or having to request, manage and monitor exemptions is both time consuming and costly. Complete removal of these materials reduces overall compliance documentation requirements. Most importantly, however, removing these materials improves the safety of the manufacturing process and for customers, because substances of
concern are completely removed from SMITHS’ processes and the eventual costly need for environmentally-safe disposal is eradicated.
Finally, thanks to the improved crimp design of the socket, an increased contact area is established between the contact body and the multi-stranded cable, ultimately contributing to the impressive low contact resistance.

Arrow Electronics and NVIDIA collaborate on AI-based steering system for SAM Car
A
rrow Electronics has designed what is said to be a first-of- its-kind, AI-powered steering system. Powered by an advanced NVIDIA processor, it uses facial recognition technology to control the latest SAM (semi- autonomous mobility) car.
Quadriplegic race car driver Sam Schmidt recently drove at competitive speeds using the new system that he steers through head motions. Arrow engineers developed the new steering system using the latest NVIDIA Jetson AGX Orin module, which is said to be the only platform capable of delivering the high accuracy and low latency needed to
control a car at speeds up to 213 mph. A low-profile stereo camera pair located on the dash captures Schmidt’s movements in real time and feeds the data to the NVIDIA module. Using machine learning, the system processes the information and adjusts the steering angle automatically – within a few thousandths of a second.
The new AI steering replaces the car’s original four-camera steering that used an older, infrared motion-capture based technology.
“With the AI, it’s more controllable,” said Schmidt. “There’s no lag. It’s instantaneous for high speed.”
The steering enhancements could have everyday applications far beyond the racetrack. The technology could be used to control vehicles and large equipment in settings as different as farming, warehouses,
public transit and construction so the operator – physically disabled or not – could perform multiple tasks.
