Systems and methods for detection of potential obstructions in a specified space. In some embodiments, the system and / or method comprises a robotic vehicle having one or more sensors configured to collect point cloud data from locations at or near a target drop zone. At least one processor performs an object detection analysis using the point cloud data to determine if there is an object in the target drop zone. To determine if there is an object or obstruction at the target drop zone, a volume of interest that is about the size of a payload can be generated for the target drop zone. If point cloud data indicates an object within the VOI, an obstruction exists and the payload is held rather than dropped at the target drop location.

In one aspect, a method includes establishing a first communication channel between a first computing device associated with a fuel dispenser user and a second computing device configured within a fuel dispenser. The method can further include receiving, by the second computing device, first data characterizing a first authorization of the fuel dispenser user of a fuel dispenser. The method also includes determining, by the second computing device, a second authorization of the fuel dispenser user based on the first data. The method further includes controlling, by the second computing device and based on the second authorization, operation of the fuel dispenser to dispense fuel. The method also includes providing, by the second computing device via the first communication channel, second data characterizing the operation of the fuel dispenser to the first computing device. Related apparatus, systems, and articles are also described.

A method for three-dimensional (3D) imaging of coronary arteries includes acquiring a sequence of two-dimensional (2D) intravascular (IV) images of a coronary artery, extracting a set of IV longitudinal images from the sequence of IV images, detecting a lumen border of the coronary artery and a media-adventitia (MA) border of the coronary artery based on the set of IV longitudinal images, estimating a sequence of geometric mass centers based on the lumen border and the MA border, estimating a 2D motion signal from the sequence of geometric mass centers, estimating a sequence of rotations for the sequence of 2D IV images based on the 2D motion signal, generating a sequence of transformed IV frames from the sequence of 2D IV images based on the sequence of rotations and the 2D motion signal, and reconstructing a 3D image from the sequence of transformed IV frames.
