Two space travel related stories hit my desktop this week; one that rapidly generated major international headlines and one that slid very quietly onto my email screen.

The headline-hitter was the successful launch of Elon Musk’s SpaceX rocket with its payload of a Tesla sports car, complete with a dummy driver at the wheel. The second was about Gallium Nitride technology that would be suitable for space applications.

Best design practices utilize the advantages offered by eGaN FETs, including printed circuit board (PCB) layout and thermal management. As GaN transistor switching charges continue to decrease, system parasitics must also be reduced to achieve maximum switching speeds and minimize parasitic ringing typical of power converters.

Developers are hard at work on the machine learning necessary for safer and more-autonomous vehicles. But all the AI in the world won’t be enough if the car relies on inadequate sensors. That was clearly demonstrated in one fatal Tesla crash that occurred in part because the car’s camera didn’t correctly identify an oncoming truck. To ensure smart vehicles have a reliable model of surrounding objects — particularly the ones the cars identify as “threats” — most rely on one or more lidars, or laser-based remote sensors.

LAS VEGAS — Once again the marathon that is CES is drawing to a close. Four days of trade show plus two days of media events. All sprawled across five miles of Las Vegas in some insane number of hotels and conference venues. As usual, I stuck it out so you don’t have to. Here are some of the images that struck me as interesting, weird, or just plain worth remembering:

Wireless power, the ability to deliver electricity to gadgets without plugging those gadgets into a cable, is a hotbed of innovation at the moment. The dominant standard, called “Qi,” is ever under attack from other efforts.

This week saw interesting developments from Energous (WATT), which aims to transfer power via radio frequency transceivers, with limited results so far, and some controversy about its business.

There are other contenders. On Wednesday in Las Vegas, during the Consumer Electronics Show, I met with Alex Lidow, who is founder of a privately held chip company EPC of El Segundo, California.

This article takes a deep dive into lidar technology. It explains how the technology works and the challenges technologists face as they try to build lidar sensors that meet the demanding requirements for commercial self-driving cars.

The bottom line is that while bringing lidar costs down will take a significant amount of difficult engineering work, there don't seem to be any fundamental barriers to bringing the cost of high-quality lidar down below $1,000—and eventually below $100. That means the technology—and ultimately, self-driving vehicles that depend on lidar—should be well within reach for ordinary consumers.

EPC2049 GaN power transistor offers power systems designers a 40 V, 5 mΩ power transistor about 8 times smaller than equivalently rated silicon MOSFETs for point of load converters, LiDAR, and low inductance motor drive.

EL SEGUNDO, Calif. — December 2017 — EPC announces the EPC2049 power transistor for use in applications including point of load converters, LiDAR, envelope tracking power supplies, class-D audio, and low inductance motor drives. The EPC2049 has a voltage rating of 40 V and maximum R_DS(on) of 5 mΩ with a 175 A pulsed output current.

Within the AirFuel^TM Alliance booth at CES 2018, EPC will show how gallium nitride (GaN) semiconductors are at the core of large surface area wireless power. In the EPC hospitality suite, wirelessly powered systems for the home and GaN based, industry-leading LiDAR systems used in autonomous vehicles will be on display.

EL SEGUNDO, Calif. — December 2017 — Efficient Power Conversion (EPC) will be demonstrating the power of eGaN^® technology to enhance two game-changing consumer applications – wireless power and LiDAR for self-driving cars – at the 2018 Consumer Electronics Show (CES) in Las Vegas, January 9^th through the 12^th.

To ensure widespread adoption, wireless power systems need to move beyond small charging pads and become active power sources over large surface areas. For magnetic resonant systems, this demands fundamental changes in coil technology, system architecture, and power amplifiers. Gallium nitride based amplifiers have proven capable of delivering 60 W with greater than 90 percent efficiency into the transmit coil over a wide load range.
