  • Patent number: 12069472
    Abstract: Secure channel training to enhance the confidentiality level of a power domain non-orthogonal multiple access (NOMA) communication system when impaired by eavesdropping attacks coming from inside and outside of the network. In a first scenario, a cooperative jammer available in the system defines an external source of entropy that is independent of the channel variation rate. While the jammer provides secrecy inside the network, the proposed invention is configured to secure the network from outside, encoding the system information, which is exchanged during the training phase, using only the channel state. In a second scenario, the cooperative jammer is not available; with the secrecy inside and outside of the network ensured through a different parameterization. That parameterization is done in a way that the required system information is encoded using not only the channels, but also a random phase defined in the data communication phase.

  • Publication number: 20230049117
    Abstract: The invention is directed to a hydratable concentrated surfactant composition. The composition is pourable, easy to dilute, substantially free of sulfate and oil, comprises a C6-C14 acid, alcohol or both, an anionic surfactant comprising acyl isethionate and an amphoteric surfactant, zwitterionic surfactant or both. The composition is in lamellar phase and thickens and transforms to an isotropic phase upon dilution. The composition can be used as a concentrate in small volumes and diluted as used and needed or can be diluted with water in refill packaging to ensure a reduction in plastic waste.

  • Publication number: 20220108186
    Abstract: This invention is a niching optimization algorithm that provides multiple extrapolated points of a function, the maximum or minimum outputs, over one optimization run. Yet differently than existing niching algorithms, it locally ranks each local population, providing a multi-focus exploration with an equalized number of solutions inside each niche, and identifies the set of most efficient and distinct solutions, instead of the overall population of solution. As an optimization algorithm, it has broad application in artificial intelligence, and in the design of engineering systems such as aeronautical structures, etc. . . . . It also can generate a mesh for any dataset or function domain, grouping inputs by regions of similitude. Thus, it can generate a mesh for a FEM, and segment the domain of expensive metamodels, like artificial neural networks, Kriging models (KR), among others. Experiments demonstrated that with a response surface mesh, the overall training time is substantially reduced.

  • Publication number: 20210130790
    Abstract: 3D cell cultures contain hepatic cells and are infected by a pathogen. Such cell cultures are prepared by, for example, inoculating a single-cell suspension containing hepatic cells expanded in a 2D culture in an agitation-based culture system. Next, the resulting cell culture is agitated at a given agitation rate. Then, the resulting 3D cell culture containing cell aggregates is incubated with a pathogen.

  • Patent number: 10476620
    Abstract: The disclosure pertains to wireless communications and, more particularly, to the exploitation of channel gain information, advantageously where more than two transmitter/receiver pairs transmit information over a shared medium. The disclosure applies distributed interference compression (23) at the receivers (receiver 1 (8), . . . , receiver k (9), . . . , and receiver K (10)) and repetition coding (13) at the transmitters (transmitter 1 (1), . . . , transmitter k (2), . . . , transmitter K (3)). Repetition coding repeats the same symbol stream (11) several times and the distributed interference compression (23) reduces the number of interference retransmissions (15) required to obtain the interference free signal (26). The throughput achieved by previous solutions is limited to two symbols per time slot, whereas in the present disclosure throughput is enhanced and is proportional to the square root of the number of transmitter/receiver pairs considered.

  • Patent number: 9477368
    Abstract: A system and method is provided that displays cursors for street level images, where the cursor changes appearance based on the objects in the image, such as the geographic distance between the objects and the camera position and the surface of the objects. For example, the cursor may appear to lie flat against the objects in the image change size based on the distance between the camera and object's surface.

  • Patent number: 8977074
    Abstract: Photographic images can be used to enhance three-dimensional (3D) virtual models of a physical location. In an embodiment, a method of generating a 3D scene geometry includes obtaining a first plurality of images and corresponding distance measurements for a first vehicle trajectory; obtaining a second plurality of images and corresponding distance measurements for a second vehicle trajectory, the second vehicle trajectory intersecting the first vehicle trajectory; registering a relative vehicle position and orientation for one or more segments of each of a first vehicle trajectory and a second vehicle trajectory; generating a three-dimensional geometry for each vehicle trajectory; mapping the three-dimensional geometries for each vehicle trajectory onto a common reference system based on the registering; and merging the three-dimensional geometries from both trajectories to generate a complete scene geometry.

  • Patent number: 8717354
    Abstract: The present invention relates to annotating images. In an embodiment, the present invention enables users to create annotations corresponding to three-dimensional objects while viewing two-dimensional images. In one embodiment, this is achieved by projecting a selecting object onto a three-dimensional model created from a plurality of two-dimensional images. The selecting object is input by a user while viewing a first image corresponding to a portion of the three-dimensional model. A location corresponding to the projection on the three-dimensional model is determined, and content entered by the user while viewing the first image is associated with the location. The content is stored together with the location information to form an annotation. The annotation can be retrieved and displayed together with other images corresponding to the location.

  • Patent number: 8698875
    Abstract: A system and method are presented for estimating the orientation of a panoramic camera mounted on a vehicle relative to the vehicle coordinate frame. An initial pose estimate of the vehicle is determined based on global positioning system data, inertial measurement unit data, and wheel odometry data of the vehicle. Image data from images captured by the camera is processed to obtain one or more tracks, each track including a sequence of matched feature points stemming from a same three-dimensional location. A correction parameter determined from the initial pose estimate and tracks can then be used to correct the orientations of the images captured by the camera. The correction parameter can be optimized by deriving a correction parameter for each of a multitude of distinct subsequences of one or more runs. Statistical analysis can be performed on the determined correction parameters to produce robust estimates.
