    Abstract: A cushion member having improved variable stiffness for a target is provided. The cushion member comprises a cushion housing having an interior with a variable internal pressure and an exterior surface for receiving the target. The cushion housing is arranged to be deformable and comprises granular particles disposed in the interior of the cushion housing. The cushion housing further comprises hollow particles disposed therein with the granular particles. Each hollow particle is compressible and hollow to define a void therein. The hollow particles have a size, a wall thickness, a material, and a bulk modulus defining infill properties thereof. The hollow particles and the granular particles are arranged to allow the cushion housing to be deformed upon contact with the target. The hollow particles and granular particles define a cushion infill having a variable stiffness based on the infill properties and the variable internal pressure of the interior.

    Abstract: A system for imitating target vehicle behavior in automated driving includes sensors capturing ego and target vehicle condition information, actuators selectively altering an ego vehicle state, and control modules. The control modules execute a target vehicle imitating (TVI) application. A first TVI control logic estimates a target vehicle state and trajectory. The ego and target vehicle condition information partially define the target vehicle state and trajectory. A second control logic evaluates target vehicle safety and performance constraints. A third control logic selectively initiates an imitation mode of the ego vehicle based on target and ego vehicle statuses relative to the target vehicle safety and performance constraints. A fourth control logic, models the target vehicle and optimizes a planned ego vehicle path subject to actuator constraints. A fifth control logic generates outputs to the actuators to cause the ego vehicle to follow the planned path and imitate the target vehicle.

    Abstract: An apparatus includes a compute device having a microcontroller unit circuit, multiple processing circuits, and a backplane bus. Initial unsecured communications through the backplane bus are restricted. The microcontroller unit circuit is operational to authenticate the processing circuits with a plurality of processor attestations over a local area network bus based on a secure onboard communication protocol of an automotive open system architecture, a symmetric key, and a message authentication code. The processing circuits are operational to reply to the processor attestations over the local area network bus, and verify the microcontroller unit circuit based on the secure onboard communication protocol, the symmetric key, and the message authentication code received from the microcontroller unit circuit. Secure communications through the backplane bus among the processing circuits is enabled based on the authentications of the processing circuits and the verifications of the microcontroller unit circuit.
