Abstract: A multifocal display device has a focus tunable lens (FTL) and a controller configured to shift a focus of the FTL from a first focal plane to a second focal plane by applying a compensated control signal to the FTL. The controller is configured to generate a current compensated control signal value, which is a value of the compensated control signal for a current point in time, based on one or more previous compensated control signal values, which are values of the compensated control signal at one or more previous points in time.

Abstract: Embodiments provide an audio signal encoding method comprising the steps of: collecting audio signal samples (114), determining sinusoidal components (312) in subsequent frames, estimation of amplitudes (314) and frequencies (313) of the components for each frame, merging thus obtained pairs into sinusoidal trajectories, splitting particular trajectories into segments, transforming (318, 319) particular trajectories to the frequency domain by means of a digital transform performed on segments longer than the frame duration, quantization (320, 321) and selection (322, 323) of transform coefficients in the segments, entropy encoding (328), outputting the quantized coefficients as output data (115), wherein segments of different trajectories starting within a particular time are grouped into Groups of Segments (GOS), and the partitioning of trajectories into segments is synchronized with the endpoints of a Group of Segments (GOS).

Abstract: The present invention provides a device comprising circuitry configured to obtain a plurality of initial two-dimensional, 2D, images which together represent an initial three-dimensional, 3D, image, wherein each initial 2D image is associated with one of a plurality of focal planes. The device is further configured to generate one or more blurred versions of each of the initial 2D images on one or more of the focal planes other than its associated focal plane; generate a high passed version of each of the initial 2D images on its associated focal plane; and generate a plurality of final 2D images by generating for each focal plane a final 2D image based on the high passed version of the initial 2D image associated with that focal plane and one or more blurred versions generated on that focal plane from one or more of the other initial 2D images.

Abstract: A focus tunable optical system includes a compound lens, which includes a plurality of focus tunable lenses. Further, the focus tunable optical system comprises a controller, which is configured to shift a focus of the compound lens from a first focal plane to a second focal plane. To this end, the controller is configured to apply, individually to each focus tunable lens of the plurality of the focus tunable lenses, a control signal having a first value for the first focal plane and a second value for the second focal plane.

Abstract: A device and method perform Simultaneous Localization and Mapping (SLAM). The device includes at least one processor configured to perform the SLAM method, which includes the following operations. Preprocess, in a first processing stage, a received data sequence including multiple images recorded by a camera and sensor readings from multiple sensors in order to obtain a frame sequence. Each frame of the frame sequence includes a visual feature set related to one of the images at a determined time instance and sensor readings from that time instance. Sequentially process, in a second processing stage, each frame of the frame sequence based on the visual feature set and the sensor readings included in that frame in order to generate a sequence mapping graph. Merge, in a third processing stage, the sequence mapping graph with at least one other graph, in order to generate or update a full graph.
