  • Patent number: 11010622
    Abstract: A method of non-line-of-sight (NLoS) obstacle detection for an ego vehicle is described. The method includes capturing a sequence of images over a period with an image capture device. The method also includes storing the sequence of images in a cyclic buffer. The method further includes registering each image in the cyclic buffer to a projected image. The method includes performing the registering by estimating a homography H for each frame of the sequence of images to project to a view point of a first frame in the sequence of images and remove motion of the ego vehicle in the projected image. The method also includes enhancing the projected image. The method further includes classifying the projected image based on a scene determination. The method also includes issuing a control signal to the vehicle upon classifying the projected image.

  • Publication number: 20210049382
    Abstract: An object detection method includes receiving sensor data including a number of images associated with a sensor region as the actor traverses an environment, the plurality of images characterizing changes of illumination in the sensor region over time, the sensor region including a region to be traversed by the actor in the future, processing the plurality of images determine a change of illumination in sensor the region over time. The processing includes registering the plurality of images to a common coordinate system based at least in part on odometry data characterizing the actor's traversal of the environment, determining the change of illumination in the sensor region over time based on the registered plurality of images. The method further includes determining an object detection result based at least in part on the change of illumination in the sensor region over time.

  • Patent number: 9576255
    Abstract: The system provides a method and apparatus for providing controlled access to events, premises, transportation, and the like. In one embodiment, the system provides a ticket that is tied to a user and/or a device. The ticket in one embodiment comprises a dynamic link whose privileges and permissions can be controlled by a system controller so that use, re-use, and re-sale of the ticket can be controlled by the issuer and not by a purchaser or user. The system in one embodiment uses a reader/scanner associated with a controlled entrance that can receive tickets via scanning or some other form of electronic communication. In one embodiment, the system uses radio signals, such as Wi-Fi, Bluetooth, NFC (Near Field Communication) from a mobile device to determine if access should be granted.

  • Publication number: 20160283983
    Abstract: The system provides a method and apparatus for allowing the creation of customized private social networks through a dashboard interface. A user invokes the social network building interface and selects desired features for the network by selecting one of a plurality of possible features. When a feature is selected, the system guides the user through parameters and metrics to implement that feature as desired by the user. The system is implemented through a cloud based architecture that provides components that are used in the private social network, including services such as database, caching, load balancing, security, encryption, dynamic link control, and others. These services and components are accessed and invoked through a series of function calls through an API that allows the creation of a scalable number of private social networks.

  • Publication number: 20160277410
    Abstract: The system provides a method and apparatus for providing a dynamic link to ephemeral content. The system and method receives a content from a first device. The method and apparatus receives a set of permissions associated with the content. The method and apparatus provides the dynamic link to the content to a second device based on the permissions associated with the content.

  • Publication number: 20160070926
    Abstract: The system provides a method and apparatus for defining rights and permissions for content that allows for subsequent modification of creator owned content, but restricted to permissions and changes associated with the content. The permissions may be one or more from a plurality of possible modifications, time periods, distribution rights, and the like, and include a fee associated with the right to modify. In one embodiment content is accessed via a dynamic link, and the dynamic link includes rules, controls, and restrictions that limit the ability to modify the content to an agreed upon number and type of changes.
