Hi Sirod,
A bit of digging on Xperi found no relevant patents, but a search for their CTO Petronel Bigioi found several patents, including:
US11361525B2 Electronic device for performing biometric identification
View attachment 13388
View attachment 13385
This patent, priority 2019, names Petronel Bigioi (PB) as inventor, but the owner is FotoNation, an Irish company. Now there could be two PBs, but it is possible PB now works for Xperi. There may also be a licence agreement (takeover?) between Xperi and Fotonation.
The photosensor plate combines the normal RGB pixels with infrared pixels.
Quoting PB
"T
he neuromorphic sensors capture information at an equivalent frame rate of 10,000 frames per second without the need for active lighting. This enables better low-light performance for driver monitoring functions, as well as unprecedented features such as saccadic eye movements or micro-expressions, critical next steps for next-generation passenger experiences."
The low-light conditions imply infrared, so it is highly probable that PB is talking about the FotoNation patents.
Xperi are working in the same area as nViso, but that would not necessarily exclude Xperi having an Akida licence.
Their blurb:

states that:

TS AutoSense Single Camera Driver and Occupancy Sensing:

uses proprietary AI/ML technology to ensure the quality and reliability of drowsiness or attentiveness analytics
However, FotoNation has several other patents invented by PB, including:
EP3408798A1 A CONVOLUTIONAL NEURAL NETWORK dating from 2016
View attachment 13391
which relates to CNN and definitely does not use Akida.
Here is another trick which PB invented for biometric sensing:
US10310145B2 Image acquisition system
View attachment 13394
A
n image acquisition system for acquiring iris images for use in biometric recognition of a subject includes an optical system comprising a cluster of at least 2 lenses arranged in front of a common image sensor with each lens optical axis in parallel spaced apart relationship. Each lens has a fixed focus and a different aperture to provide a respective angular field of view. The lens with the closest focus has the smallest aperture and the lens with the farthest focus has the largest aperture so that iris images can be acquired across a focal range of at least from 200 mm to 300 mm.

P
etronel has more than 250 granted and published U.S. and international patents to date. Petronel is an IEEE fellow with over 20 years of experience in the digital still camera and mobile phone industries, working in both signal processing and connectivity. A co-founder of several successful companies (including FotoNation), he is also a pioneer of digital camera connectivity, a co-author and actively involved in the picture transfer protocol (PTP) and PTP-over-IP networks communication standards.
