The Natural 3D Lightfield Instrument Cluster brings augmented reality (AR) functionality to car dashboards without requiring adaptive eyewear. The system replaces traditional readouts such as speedometers and fuel gages with a 3D screen that can display navigation route data and other information. Developers are studying how to implement video calling, Internet browsing, or television and movies.

“The car is clearly the next frontier for mobile,” says David Fattal, Leia Inc. co-founder and CEO. “To us, it’s a bigger, more immersive version of a smartphone with full 3D awareness of its environment. The vehicle is a logical place to deploy our growing Lightfield ecosystem of immersive gaming, video streaming, social sharing, and even e-commerce activities.”

The 3D-image produced by the Lightfield display uses eight perspectives of the same object that subtly vary according to the point-of-view through blocking or refracting light.

3D ultrasonic sensor

The TS3 3D ultrasonic sensor provides object detection and situational awareness. The sensors achieve up to a 160° field-of-view and provide simultaneous 3D measurements for multiple objects within the scanning area. The operation mimics echolocation used by bats and dolphins for navigation and orientation.

Combining hardware with proprietary signal processing algorithms, it offers real-time processing capabilities while keeping data transmission bandwidth and power consumption low.

TS3 sensors perform independently of ambient light conditions and can detect mirroring and transparent surfaces. The generated 3D point cloud can be fused with data from other system-relevant sensors.

The TS3 can detect objects up to 5m away and has a 28Hz scan rate. It returns up to 200 points per second with each 3D point corresponding to the Cartesian coordinates and an additional volume measurement of the ultrasound wave’s echo from an object’s surface.


Cylinder liner

Megabond cylinder liner technology provides robust durability for high performance on engines with cast aluminum cylinder blocks. They offer 2x the mechanical bond strength of existing liners, combined with excellent thermal conductivity, to meet the increased mechanical and ther-mal loads of tomorrow’s high-efficiency engines. The new technology is suitable for light vehicles using gasoline, diesel, and alternative fuel powertrains as well as hybridized versions.

The liners use an aluminum/silicon alloy deposited around a cast iron liner by wire arc spray, prior to casting the aluminum block around it. The design creates an exceptionally strong intermetallic bond between the liner and the aluminum block.

Megabond cylinder liners were initially developed to meet the requirements of next-generation engines with ultra-close bore spacing, which can place severe demands on liner stability and thermal performance but constrain liner thickness.

Megabond liners are tolerant of a wider variation in cylinder block casting properties. Improved robustness means the foundry is not limited to a narrow window within parameters of the casting process to ensure a successful finished product.

Seating technology

FreeForm seat trim cover techniques provide a clean, sculpted, seamless styling surface, increasing design possibilities. It can achieve design details as sharp as a 3mm-to-4mm radii, compared to 20mm-to-25mm radii for traditional cut and sew.

The technology offers improved seat back comfort with highly concave surfaces and contours that hug the human shape. Back panels have a soft touch and provide up to 4" of additional rear seat knee clearance. Seats are easier to clean because they feature simple construction with a seamless surface. In future mobility scenarios such as ride sharing, seat covers can be swapped during routine maintenance using a zipper.

The sculpted, seamless surface offers more than 102mm of concavity – nearly impossible with traditional cut and sew – resulting in added comfort and styling.

Increased rear-form concavity, coupled with bolsters to support the lower back, reduces fatiguing micro-motions of riders’ spines.

FreeForm is 4x more breathable than other molded trim technologies, increasing seat comfort. Hidden tie-downs eliminate up to 80 traditional trim attachment components.

The FreeForm manufacturing process is flexible and can be used in low- and high-volume vehicle programs. It enables more surface control and repeatable precision, reducing manufacturing floor time spent finessing seat covers. The technology can be used on leather, cloth, or vinyl.

Magna International Inc.

High-efficiency alternator

Alternators for gasoline and diesel engines, using a high-efficiency diode developed with Hitachi Power Semiconductor Device Ltd., are in production. The jointly developed diode significantly reduces power conversion loss by increasing the function’s efficiency. Power generation efficiency increases by about 6% compared to conventional products. If diodes worldwide were replaced with the new models, carbon dioxide emissions would fall by 30 tons annually.
