A Curious Engineer Overturns Waymo Key LiDAR Patent

Ars Technica: Following a complaint by Eric Swildens, the USPTO has rejected all but three of 56 claims in Waymo's US9368936 patent. The USPTO found that some claims replicated technology described in an earlier patent from Velodyne, while another claim was simply "impossible" and "magic."

"The patent shouldn't have been filed in the first place," Swildens said. "It's a very well written patent. However, my personal belief is that the thing that they say they invented, they didn't invent."

The 936 patent played a key role in last year's lawsuit with Uber. In December 2016, a Waymo engineer was inadvertently copied on an email from one of its suppliers to Uber, showing a LiDAR circuit design that looked almost identical to the one shown in the 936 patent:


Swildens said to Wired in 2017: "I couldn't imagine the circuit didn't exist prior to this patent." He then spent $6,000 of his own money to launch a formal challenge to 936 and won in the court.

Thanks to AM for the pointer!

Polarization Sensing in LWIR Band

KB ViTA kindly sent me an info about their latest LWIR camera that senses polarization: " It all was started with the fact KB ViTA has developed a very sensitive thermal imaging module VLM640, which had a sensitivity of at least 20 mK in 8 — 12 µm band. The sensor manufacturer turned to KB ViTA and offered an engineering sample from an experimental wafer of bolometric detectors with integrated polarization filters. For KB ViTA it was honorable but, at the same time, there was no understanding of what it is expected to ultimately obtain. The technology and the very idea of seeing the own polarization of the thermal photons of objects that surround us is absolutely new and hardly anyone has experience of processing such information. Below we will show you how the polarization in the IR spectrum looks. There were a polarizing sensor and electronics from VLM640 camera with 20 mK sensitivity. The interesting thing about the sensor is each pixel in the group of four is covered with a p...
