  • Publication number: 20190137411
    Abstract: Stray and air scattered light can be reduced by configuring a size of the collection area of a sensor, which reduces a source of sensitivity-limiting noise in the system. By adjusting a size of the collection area, stray deep ultraviolet light and air-scattered deep ultraviolet light can be reduced. A servo can control a position of an illumination spot that is collected by the time delay and integration sensor.

  • Patent number: 10275023
    Abstract: In a virtual reality system, an optical tracking device may detect and track a user's eye gaze direction and/or movement, and/or sensors may detect and track a user's head gaze direction and/or movement, relative to virtual user interfaces displayed in a virtual environment. A processor may process the detected gaze direction and/or movement as a user input, and may translate the user input into a corresponding interaction in the virtual environment. Gaze directed swipes on a virtual keyboard displayed in the virtual environment may be detected and tracked, and translated into a corresponding text input, either alone or together with user input(s) received by the controller. The user may also interact with other types of virtual interfaces in the virtual environment using gaze direction and movement to provide an input, either alone or together with a controller input.

  • Publication number: 20190095764
    Abstract: Techniques are disclosed for identifying objects in images. In one embodiment, transfer learning is employed to build new classifiers on top of pre-trained machine learning models, such as pre-trained convolutional neural networks (CNNs), by re-training classification layers of the pre-trained machine learning models using new training data while keeping feature detection layers of the pre-trained machine learning models fixed. Subsequently, the re-trained machine learning models may take as input images depicting regions of interest extracted from larger images using a sliding window, a saliency map, an image disparity map, and/or a region of interest detection technique, and output classifications of objects in the input images. In addition, a meta model may be learned that aggregates outputs of the re-trained machine learning models for robustness.

  • Publication number: 20190095877
    Abstract: Techniques are disclosed for rental vehicle damage detection and automatic rental vehicle management. In one embodiment, a rental vehicle management application receives video and/or images of a rental vehicle's exterior and dashboard and processes the video and/or images to determine damage to the vehicle as well as the vehicle's mileage and fuel level. A machine learning model may be trained using image sets, extracted from larger images of vehicles, that depict distinct types of damage to vehicles, as well as image sets depicting undamaged vehicles, and the management application may apply such a machine learning model to identify and classify vehicle damage. The management application further determines sizes of vehicle damage by converting the damage sizes in pixels to real-world units, and the management application then generates a report and receipt indicating the damage to the vehicle if any, mileage, fuel level, and associated costs.

  • Publication number: 20190068742
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing an electronic resource to multiple users that are associated with the electronic resource. In some implementations, a method includes identifying multiple users, as a proper subset of users of a satellite communication network, that are each associated with an electronic resource. Satellite terminals of the satellite communication network corresponding to the identified users are identified. Satellite transmission data is generated that includes the electronic resource and designates the identified satellite terminals. A satellite gateway transmits the satellite transmission data over the satellite communication network in a satellite broadcast to the identified satellite terminals, such that the identified satellite terminals can concurrently receive data associated with the electronic resource without sending a request for data associated with the electronic resource.

  • Publication number: 20190039633
    Abstract: Techniques are disclosed for detecting and reporting railroad track anomalies. In one embodiment, a track inspection application is configured to receive images (or other sensor data) depicting a railroad track captured by cameras mounted on a train, compare the captured images with corresponding reference images (or other sensor data) captured from substantially the same locations and vantage points, and detect anomalies in the railroad track represented by differences between the captured images and corresponding reference images. In another embodiment, the inspection application may generate a three-dimensional (3D) model of the railroad track based on depths determined through, e.g., triangulation, and determine the railroad track's geometry from the 3D model.
