  • Patent number: 11912292
    Abstract: The technology relates to partially redundant equipment architectures for vehicles able to operate in an autonomous driving mode. Aspects of the technology employ fallback configurations, such as two or more fallback sensor configurations that provide some minimum amount of field of view (FOV) around the vehicle. For instance, different sensor arrangements are logically associated with different operating domains of the vehicle. Fallback configurations for computing resources and/or power resources are also provided. Each fallback configuration may have different reasons for being triggered, and may result in different types of fallback modes of operation. Triggering conditions may relate, e.g., to a type of failure, fault or other reduction in component capability, the current driving mode, environmental conditions in the vicinity of vehicle or along a planned route, or other factors.

  • Patent number: 11360538
    Abstract: A cradle apparatus detects spatial distances from target objects positioned in adjacency to the cradle apparatus, and communicates with a mobile communications device for selectively powering off/on the visual display of the mobile communications device based on its distance from a target object. The cradle apparatus includes a cradle assembly, at least one distance sensor, and sensor support circuitry. The cradle assembly is configured for cradling the communications device and displaying a visual display of the communications device as cradled by the cradle assembly, optionally at an oblique angle relative to a support surface. Each distance sensor is positioned by the cradle assembly for detecting the relative distance of select objects positioned in adjacency to the visual display. The sensor support circuitry communicates each distance sensor to a switch or circuit board for powering off or powering on the visual display depending on its distance from the target object.
