Abstract: A set of 3D user-designed images is used to create a high volume of realistic scenes or images which can be used for training and testing deep learning machines. The system creates a high volume of scenes having a wide variety of environmental, weather-related factors as well as scenes that take into account camera noise, distortion, angle of view, and the like. A generative modeling process is used to vary objects contained in an image so that more images, each one distinct, can be used to train the deep learning model without the inefficiencies of creating videos of actual, real life scenes. Object label data is known by virtue of a designer selecting an object from an image database and placing it in the scene. This and other methods care used to artificially create new scenes that do not have to be recorded in real-life conditions and that do not require costly and time-consuming, manual labelling or tagging of objects.

Further, the method comprises repeating the above method steps for all of the remaining sections of the multi-spectral X-ray target.

Abstract: Provided are integrated locks, aircraft galley systems using such locks, and aircraft including such galley systems. An integrated lock has a low profile and provides secure locking and visual indication of the lock status to meet various FAA regulations. The visual indication may be provided mechanically (e.g., by moving a two-color indicator between two positions) or electronically (e.g., by triggering a switch connected to a light or an electro-chromic device). Furthermore, a main indicator may be connected to multiple different locks to provide a combined visual indication of the status of all locks. A visual indicator may be disposed on a galley system frame. Each integrated lock may include a handle portion and a locking portion connected to the handle portion and configured to engage the galley system frame when the handle portion is in the locked position and the door is closed.
