Archipelago and Seoul Settle Patent Disputes

Seoul Semiconductor based in Ansan, South Korea, reported that it and Seoul Viosys Co., Ltd. have resolved two patent infringement lawsuits it filed against Archipelago Lighting, Inc. in the U.S. Federal District Court for the Central District of California. Archipelago sells LED bulbs.

In 2017, Seoul filed the company’s first patent infringement lawsuit against Archipelago for the alleged infringement of twelve LED patents covering various aspects of Seoul’s long-established Acrich technology. A few months afterward, Seoul filed a second patent lawsuit against Archipelago accusing the company of selling additional products that infringe eight other Acrich technology patents.

In the lawsuits, Archipelago acknowledged that several third-party suppliers produced the LED components in its LED bulbs. Although Archipelago admitted that the company had no knowledge of any Seoul Semiconductor patents, it did not dispute that the LED bulbs in question infringed Seoul Semiconductor’s patents. According to Seoul, Archipelago also did not dispute the validity of the relevant its patents and agreed to pay a license fee as part of its commitment to respect the intellectual property rights of others.

Court Ruled in Seoul’s Favor Due to Archipelago Admissions

The California Central district court ruled in favor of Seoul Semiconductor in these cases based upon Archipelago’s admissions.

Osram Opto and Joyson Implement “Super Cruise” Technology in Cadillac CT6 Using IR LEDs

Osram Opto Semiconductors reported that it and Joyson Safety Systems are outfitting the new Cadillac CT6 with a novel system for semi-autonomous driving. Joyson claims that ‘Super Cruise’ is the industry’s first true hands-free driving technology for the highway. The system employs Osram’s infrared and LED components. Joyson Safety Systems’ steering wheel for the Cadillac CT6 employs these embedded infrared and LED components to monitor driver attentiveness through the tracking of their head position to ensure drivers are watching the road ahead while ‘Super Cruise’ is engaged.

Joyson Created Steering Wheel Featuring Osram Opto IR LEDs

According to Osram, ‘Super Cruise’ embodies the next evolution of adaptive cruise control, and it works only if the driver is paying attention to the road ahead. For this reason, Joyson Safety Systems worked with Osram to create a steering wheel with an embedded infrared camera that tracks the driver’s head position and gaze to confirm the driver’s eyes are on the road at all times.

“Super Cruise” System Alerts Drivers Not Paying Attention

If the driver looks away from the road for too long, the ‘Super Cruise’ system will send a series of alerts for the driver to resume supervision of the road. In the unlikely event that a driver becomes completely unresponsive, the Cadillac CT6 utilizes the full capability of onboard driver assistance technologies to bring the car to a controlled stop.

Cadillac plans to expand the rollout of Super CruiseTM, a hands-free driver assistance feature for the freeway that uses IR LEDs from Osram Opto Semiconductors embedded in a steering wheel produced by Joyson Safety Systems.

Cadillac plans to expand the rollout of Super CruiseTM, a hands-free driver assistance feature for the freeway that uses IR LEDs from Osram Opto Semiconductors embedded in a steering wheel produced by Joyson Safety Systems.

The Joyson Safety Systems’ steering wheel is equipped with Osram’s Oslon Black SFH 4715S IREDs to helps track eye movement. It also features Osram’s RGB Multiled to indicate to the driver when the ‘Super Cruise’ system is operating and what function the system is currently performing. For instance, the LED lights turn green when the ‘Super Cruise’ system is engaged. The lights turn blue when the system senses the driver might not be paying attention, and turn red when the system disengages. The LEDs also blink on and off when the IREDs are blocked from viewing the driver’s eyes.

“We are pleased to partner with Joyson Safety Systems on Super Cruise,” said Rajeev Thakur, marketing manager, Osram Opto Semiconductors. “Our visible and infrared LEDs place us in a unique position to collaborate with a variety of dynamic development partners looking to innovate advanced driver assistance systems – from driver monitoring, to LiDAR, adaptive headlights and more.
