Abstract: In some implementations, a server device may generate a machine readable code that conveys first information associated with a first entity. The server device may provide an indication of the machine readable code that indicates the first information. The server device may obtain a request to update information conveyed by the machine readable code, the request including an indication of at least one of the machine readable code or the first information. The server device may modify the first information conveyed by the machine readable code to second information, based on the request and based on authenticating the request, wherein the second information includes a first secure information layer indicating the first information and a second secure information layer indicating information indicated by the request. The server device may provide, to the communication device, an indication of at least one of the machine readable code or the second information.

Abstract: Systems, methods, and apparatus related to cruise control for a vehicle. In one approach, speed for a first vehicle is controlled in a first mode using data from sensors. The speed is controlled while keeping at least a minimum distance from a second vehicle being followed by the first vehicle. In response to determining that data from the sensors is not usable to control the first vehicle (e.g., the data cannot be used to measure the minimum distance), the first vehicle changes from the first mode to a second mode. In the second mode, the first vehicle maintains a constant speed and/or obtains additional data from sensors and/or computing devices located externally to the first vehicle. In another approach, the additional data can additionally or alternatively be obtained from a mobile device of a passenger of the first vehicle. The additional data is used to maintain a safe minimum distance from the second vehicle.

Abstract: Systems, methods, and apparatus related to sensor data processing for a vehicle to improve operation when sunlight or other bright light enters a sensor of the vehicle. In one approach, adjustable filtering is configured for a sensor of a vehicle. In one example, an optical filter is positioned on the path of light that reaches an image sensor of a camera. For example, the filtering improves ability to stay in adaptive cruise control when driving into direct sunlight at sunset. The optical filters can have controllable properties such as polarization. In one example, a controller of the vehicle is configured to automatically adjust the properties of the optical filter to improve image quality to improve object recognition. In another example, a camera is configured with composite vision that uses sensors in different radiation spectrums (e.g., visible light, and infrared light). The composite vision can provide enhanced vision capability for an autonomous vehicle that is driving in the direction of the sun.
