  • Publication number: 20220214275
    Abstract: A measurement apparatus includes a generator that causes electromagnetic waves to be incident on a sample, a receiver that receives electromagnetic waves reflected by the sample, and a controller that controls the generator and receiver. The sample includes a first layer on which the electromagnetic waves are incident and a second layer stacked on the first layer. The controller detects whether a third layer is present between the first and second layers based on the electromagnetic waves incident on the sample from the generator and the electromagnetic waves received by the receiver. The generator causes the electromagnetic waves to be incident at an angle such that the electromagnetic waves are totally reflected between the first and third layers and/or between the first and second layers.

  • Patent number: 11267480
    Abstract: A travel control apparatus is provided. The travel control apparatus acquires driver abnormality information indicative of an abnormality of a driver of a vehicle, makes a determination that the driver is in a driving difficulty state based at least on the driver abnormality information, and activates a lane departure prevention function and a cruise control function of the vehicle at substantially the same time during a time period between when the driver abnormality information is acquired and when the driving difficulty state is determined. Together with activating the lane departure prevention function and the cruise control function, the travel control apparatus outputs notification request information to a human machine interface controller controlling a notification device which issues a notification to a passenger of the vehicle. The notification request information causes the notification indicative of activation of the lane departure prevention function and the cruise control function to be issued.
