Abstract: A vehicular synchronization system includes an image sensor of a vehicle. The image sensor captures image data for an image sensor field of view. The vehicular synchronization system also includes a light sensor having a radial view. The light sensor captures light data from around the vehicle in a full rotation. The vehicular synchronization system includes a synchronization control unit having a data receiving module, a trigger time determination module, a timer module, and a sensor trigger module. The data receiving module receives a data packet from the light sensor. The trigger time determination module determines a trigger time when a desired light sensor orientation overlaps with the image sensor field of view. The timer module sets a timer to elapse at the trigger time. The sensor trigger module controls the image sensor to capture image data at the trigger time when the timer elapses.

Abstract: At least first nodes and second nodes of a decision tree are stored within a memory of an information handling system. The first nodes include a first parent node and first remaining nodes that descend from the first parent node. The second nodes include a second parent node and second remaining nodes that descend from the second parent node. The first nodes are grouped into a first packed node stored in first physically contiguous locations of the memory. The first nodes are sequenced in the first physically contiguous locations according to respective depth levels of the first nodes within the decision tree. The second nodes are grouped into a second packed node stored in second physically contiguous locations of the memory. The second nodes are sequenced in the second physically contiguous locations according to respective depth levels of the second nodes within the decision tree.

Abstract: An apparatus and method are provided to determine the occurrence and location of an interaction with an interface, particularly with an image of a user interface that may be projected or otherwise produced on a surface. The apparatus uses one or more single-element sensors (such as a photodiode) to sense and capture light readings of a scene, the readings corresponding to a plurality of structured light images injected within the presentation of the interface. The readings are compared to a baseline set of readings to determine the occurrence and location of an interaction event by an obstacle (i.e., a finger or a stylus) such as a touch event or a movement of the obstacle.

Abstract: In response to a query of a decision tree, a first packed node of the decision tree is copied from a system memory into a direct memory access (“DMA”) memory. In response to copying the first packed node from the system memory into the DMA memory, copying is initiated of a second packed node of the decision tree from the system memory into the DMA memory, up to a limit of then-currently available space within the DMA memory. Concurrently with copying the second packed node from the system memory into the DMA memory, the first packed node is evaluated in the DMA memory. In response to evaluating the first packed node, the second packed node is evaluated in the DMA memory without waiting for additional copying of the second packed node from the system memory into the DMA memory.
