Abstract: This method can be used to locate or identify an object in an electrically conductive medium with a detection system that comprises n electrodes in direct electrical contact with the conductive medium. The n electrodes can be placed in at least three different states: transmitting, receiving, disconnected. Before a series of measurements, the operating point of the detection system is determined according to a given a priori setpoint, or a previous configuration of the system, or a previous measurement result of one of the electrodes, by the configuration of the state of each of the electrodes, the frequency of a sinusoidal component of an electrical signal transmitted by one of the transmitting electrodes, or the amplitude of the electrical signal transmitted by one of the electrodes configured in the transmitting or receiving state.

Abstract: A method for implementing linear view-change in a BFT protocol running on a distributed system including n replicas, wherein no more than t of the n replicas are faulty, and wherein the BFT protocol enables the non-faulty replicas to agree on how to sequence execution of a plurality of service operations originating from one or more clients. The method including executing, among and by the n replicas, a phase φ of the BFT protocol, communicating instances of a lock certificate being associated with said phase; and if 2t+1 communicating instances of said lock certificate are not received by the n replicas within a predetermined timeout period, initiating a view-change with at least the following step: if said current phase φ is different than 1, each replica Pi(i=1 . . . n) sets φi the highest phase up to said current phase.

Abstract: The disclosure describes one or more embodiments of systems, methods, and non-transitory computer-readable media that utilize a sharpness map that includes information on how to filter a displacement map on a per-texel basis to preserve sharp features while sampling a displacement map. For instance, the disclosed systems utilize a sharpness map that encodes combinable patterns to represent discontinuities of features within a displacement map. In some embodiments, the disclosed systems generate a sharpness map having texels encoded with discontinuity configurations that are referenced to control filtering (e.g., via interpolation) of a displacement map such that sharp features within the displacement map are not lost (due to smoothing during interpolation). For example, the disclosed systems filter feature values of a displacement map using discontinuities identified within a sharpness map to interpolate when the feature value(s) and a sampling point are identified as being on the same side of a discontinuity.

Abstract: The contact lens (100) for augmented reality comprises: a transparent body (102) designed to be placed on an eye (104); and at least one augmented reality module comprising an optical source (114) attached to the transparent body (102) and designed to emit a light into the transparent body, and an optical element (116) attached to the transparent body (102) and designed to receive the light from the optical source (114) and send it in the direction of the eye (104).
The optical element (116) is a hologram designed to diffract the received light as a holographic image in the direction of the eye (104).-

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for generating enriched light sources by utilizing surface-centric representations of three-dimensional surfaces. Specifically, the disclosed system utilizes a surface-centric re-parameterization that combines geometric and algebraic components of a sphere to model different light source types in a continuous range of lighting configurations. The disclosed systems utilize a set of intuitive parameters to determine a shape and emission parameters for generating an enriched light source. Additionally, the disclosed system provides a set of interactive light source controls to modify a position, orientation, shape, emittance, and lighting attenuation over distance of a light source within a three-dimensional environment. The disclosed system determines the light source controls based on sets of three-dimensional interaction primitives to control one or more parameters of the light source. The disclosed system provides the light source controls for consistently modifying various light source types within the three-dimensional environment.

Abstract: An embodiment may involve: (i) obtaining a set of data records that include respective pluralities of tuples characterizing operation of communication sessions in a network and that identify hardware or software components related to the network that were involved in the communication sessions, (ii) determining degrees to which signatures in the pluralities of tuples are associated with communication problems in the network; (iii) identifying, from the degrees, a subset of the signatures most associated with the communication problems; (iv) grouping specific pairs from the subset of the signatures into equivalence classes based on co-occurrence of signatures of the specific pairs within the data records; (v) generating and pruning a dependency graph between the equivalence classes; (vi) from the equivalence classes remaining in the dependency graph, selecting a subset of the hardware or software components related to the network that are candidates for involvement with the communication problems.

Abstract: A method for determining the position of a decoy using at least one receiver, the method includes a step for detecting a decoy attack, a step for correcting the clock bias delivered by the receiver based on an estimated drift (Dj) of the clock of the receiver. The method comprises a step for differential measurements using at least three corrected clock biases (CBjcorr(t″), CBkcorr(t″), CBlcorr(t″)) and a localization step for determining the position of the decoy.

Abstract: The present invention proposes a method and associated device for inserting tuples into a watermarked database without having to remove the watermarking from all or a part of the database before inserting each tuple. To achieve this, the invention consists of storing, in watermarking metadata, the type of group or class wherein the tuples of the database have been distributed during the watermarking of the database. For each type of group or class, a rule defining a modification of the value of at least one property on which the watermarking is carried is also stored in the watermarking metadata, depending on an insertion force parameter. Each tuple to be inserted is watermarked by applying the modification rule according to the group to which the tuple belongs. Due to the rule used, the insertion of the watermarked tuple does not modify the type of group it belongs to.
