TLS,
My guess was Semicast was referring to Templeton Peck aka Faceman rather than MR T. FMS

Also Friday is Patent day but it's quiet out there across the board.
Hi JC, I am falling behind again.

VERIFICATION OF VEHICLE OPERATOR AWARENESS BEFORE TRANSITION FROM AUTONOMOUS-MODE TO MANUAL-MODE
Interesting patent it describes a TMS rather than DMS. It is about the thought processes around the transition and what needs to be verified so that the vehicle can confirm that the driver has seen each of the necessary objects and hopefully gained sufficient situational awareness before the vehicle relinquishes control, if necessary it will prompt for what you didn't see so that it can close the loop. However, the is no IP about how the internal/external views are combined.
TMS is what Alex Roy, and today, Semicast have been pushing as the next step on top of DMS.
Of course the intellectual and business question is... Should SEE try to own that space too?
(Today) I think it is not our role. It should be part of the AV stack, or advanced cruise control. So would be developed by the Tier 1 (or tier 2)to suit what the OEM wants. We are of course the trusted partner that is essential for this to work. Delphi's comments about hats and shade may be due to the older technology that they were working with in 2018 when I presume this was first written. That could have been using old development hardware with old software, or could have been an inferior supplier's system
While we're on the subject of Glare.
Subaru's Driver Monitoring System explained.
'This relatively new technology does have some limitations. In order to work effectively, the DMS requires an unimpeded view of the driver’s face that can be reduced or completely blocked by a face covering or hat casting shade. And while the infrared camera can see through glasses, it can be affected by reflections or dark or polarised sunglasses'.

TLS,
The SEE patent that describes in/out camera fusion is;
SYSTEM AND METHOD FOR IDENTIFYING A CAMERA POSE OF A FORWARD FACING CAMERA IN A VEHICLE
https://worldwide.espacenet.com/publicationDetails/description?CC=US&NR=2019266751A1&KC=A1&FT=D&ND=3&date=20190829&DB=&locale=en_EP#
I could not see any reference to radar but it could be referred to as something I don't recognise. It also does not refer to gaze being limited by dark glasses as the Delphi Patent does. We knew why SEE always stated the importance of gaze detection thru dark glasses for driver in car monitoring but I think it's interesting that Delphi are limited by it especially in the application they describe where the camera and Radar images or frames of reference are aligned as a safety tool to detect external objects.
This I consider another barrier to entry as my own theory is that DMS in/out fusion is an important part of the data collecting process in developing the baseline safety architecture. This capacity ,and example of it's necessity to any systems development as well as the data collection is demonstrated in the recent Harman patent where the detected human gaze at external objects acts as an important back up , double check or support for the vehicle sensor system especially where the sensor system fails to recognise an object or threat.
My logic says that if other systems like the Aptiv's are handicapped by such a common feature like dark glasses then they are all but useless to the evolution of a baseline safety system . Dark glasses are not even an edge case scenario and the Aptiv system is incapacitated from what I can tell.
Interested to hear your thoughts.
JC - Thanks, I searched last night but was looking for "Aptiv" not "Delphi".
I will have a read through tonight
Hi TLS,
(Need to be brief so will look into further over coming days)
It does look like they are developing the in- Camera/out-Radar sensor fusion side of things. SEE patents I believe are both Camera in /Camera out so I'm not sure of the overlap capacity with Radar etc.
As to the question of who is doing the camera side of things I got to looking at a Aptiv Patent (below). It bought up an interesting point regarding the Dark Glasses and Object detection which is mentioned in 023 below which got me thinking about whether SEE have the same issue or have they overcome it. Will come back to this.

VERIFICATION OF VEHICLE OPERATOR AWARENESS BEFORE TRANSITION FROM AUTONOMOUS-MODE TO MANUAL-MODE
[0023] Situations may arise when it is difficult to determine the gaze-direction 26 of the operator 18 because, for example, the operator is wearing dark glasses, and/or there are instances of the primary-targets 44 that are so close together that a change in the gaze-direction 26 necessary to view each instance of the primary-targets, is difficult to distinguish. Accordingly, the verification 60 may include as an addition or alternative to monitoring the gaze-direction 26 that the operator 18 has performed a visual-sweep 80 around the host-vehicle 12 more recently than a sweep-time 82. If the gaze-direction 26 can't be detected or distinguished, movement of the head of the operator 18 may be tracked to determine that the visual-sweep 80 has been performed by the operator 18. Requirements for completing the visual-sweep 80 may include looking at the rear-view and side-view mirrors, a general scan of the area forward of the host-vehicle, and moving the head enough to indicate that the blind-spots have been checked.

JC who could be providing the sensor fusion to see which hazards the driver had not seen?
https://www.aptiv.com/newsroom/article/safety-and-convenience-innovations-powered-by-interior-sensing
One of the exciting technologies we had on display at the 2020 International Consumer Electronics Show (CES) in Las Vegas earlier this month was Aptiv’s interior sensing platform. Using the latest generation of cameras and radars, the system can recognize and respond to drivers’ and passengers’ body positioning, gestures, and eye movement. It’s a simple concept based on sophisticated software, and this one technology opens the door to a whole host of innovations ranging from comfort and convenience to lifesaving.
With Aptiv Driver State Sensing, when the car senses that the driver is distracted – or even asleep – it can sound an alert or take other appropriate actions. With 41% of crashes resulting from driver inattention or distraction, and another 7% resulting from sleep, this is a critical advance in itself.
We’re taking the idea a step further by integrating that capability with exterior sensors. For more than two decades, Aptiv has led the industry in sensing and perception systems, introducing the industry’s first automotive-grade radar, the first exterior sensor fusion of radar and vision, and the first AI-powered 3D Gesture Recognition System.
It’s with that deep background and understanding of the vehicle systems that we approached the application of interior sensing. For example, at CES we showed Aptiv Interior/Exterior Sensor Fusion, which allows a car to detect when a driver is distracted or unaware of a hazard outside the vehicle and proactively warns them to prevent a life-threatening incident before it occurs
