Abstract: Techniques for recursively generating a plug-in application recipe (PIAR) are disclosed. A PIAR management application manages a particular PIAR in an active state. The PIAR management application manages PIAR specifications, each identifying a trigger and an action. The action is conditional on the trigger. The particular PIAR includes a particular trigger and a particular action. The particular action includes a child PIAR specification that defines, for a child PIAR, a second trigger and a second action to be executed when the second trigger is satisfied. In response to detecting that the particular trigger is satisfied, the PIAR management application creates the child PIAR. The PIAR management application monitors the second trigger concurrently with the particular trigger, which the PIAR management application did not do before creating the child PIAR.

Abstract: In some implementations, vehicle data indicating a state of a vehicle is received. A current vehicle context is determined based on the vehicle data. Message data indicating one or more candidate messages is received, with each message having a corresponding display context. It is determined whether a particular message of the candidate messages has a display context that matches the current vehicle context. In response to determining that a particular message of the candidate messages has a display context that matches the current vehicle contexts, the particular message is provided for output on a display of the vehicle.

Abstract: Methods, apparatuses, computer-readable medium, and systems are disclosed for performing automatic exposure control (AEC). In one embodiment, a first digital image is captured while applying a first set of values to one or more exposure control parameters. At least one computer vision (CV) operation is performed using image data from the first digital image, thereby generating a first set of CV features from a set of possible CV features. A mask is obtained comprising a value for each feature of the set of possible CV features. Using the mask, a first measure of abundance is obtained of relevant CV features among the first set of CV features extracted from the first digital image. Based on the first measure of abundance of relevant CV features, an updated set of values is generated for applying to the one or more exposure control parameters for capturing a subsequent digital image of the scene.
