摘要： The present disclosure relates to methods, apparatus or systems for determining a final pose (21) of a rendering device. An initial pose is associated with the rendering device. A module (25) determines an intermediate pose (26) according to data from absolute pose sensors (23) and/or differential pose sensors (22). A module (27) determines the final pose (21) according to, first, a difference between the intermediate pose (26) and the initial pose information, second, the data from differential pose sensors (22), and third an evaluation of the visual perception of movements for current images (24) displayed on the rendering device.

摘要： A polar transmitter including a digital power amplifier cell that includes a first circuit and an amplifier circuit. The first circuit is configured to receive a phase modulated carrier signal and to generate a PMOS control signal and an NMOS control signal such that the PMOS control signal and the NMOS control signal have different duty cycles. The amplifier circuit is configured to receive the PMOS control signal at a PMOS transistor and the NMOS control signal at an NMOS transistor. The first circuit is configured to align the PMOS control signal and the NMOS control signal with respect to one another such that a time that the NMOS transistor and the PMOS transistor of the amplifier circuit are simultaneously conducting is minimized. The amplifier circuit is configured to generate an amplified modulated carrier signal in response to the PMOS and NMOS control signals.

摘要： In order to blur a virtual object in a video in real time as the video is acquired by a device capturing a real scene, a salient idea is used which estimates an apparent motion vector between two successive images, being captured at two successive device poses, in which the apparent motion vector estimation is based on a motion of the device. The successive images are then filtered based on the estimated apparent motion vector.

摘要： The present subject matter relates to a device for coupling two vertical components, comprising a girder made of wood, in particular glued laminated timber, and a connector for each end face of the girder for connecting the end faces to one of the vertical components each. Each connector has two fittings, one of which is mounted via one side on the respective end face of the girder and the other of which can be mounted via one side on the associated vertical component and which fittings can be brought via their other sides into abutment against one another. Further, each connector has two tensioning jaws, which grasp the fittings at diametrical ends and can be tensioned against one another by means of at least one tensioning element running approximately parallel to said other sides. The girder has a bottom chord made of steel, which bottom chord is anchored at each end face of the girder to the fitting mounted thereon. At least one tensioning member is provided for tensioning the bottom chord.

摘要： A communication system where a central node (base-station or access point) communicates with multiple clients in its neighbourhood using transparent immediate beam-forming. Resource allocation and channel access is such that the central node does not necessarily know when each client starts its transmission. Receive beam-forming in such a system is not possible, as beam-forming coefficients for each client should be selected according to the particular channel realization from that client to the central node. Each client is detected early in its transmission cycle, based on either a signature that is part of the physical characteristics unique to that client, or based on a signature that is intentionally inserted in the clients' signal, and accordingly adjusts its beam-forming coefficients.

摘要： Systems and methods for up-sampling a polar amplitude sample stream in a polar modulator are disclosed. In some embodiments, a process includes receiving, at a polar modulator, an in-phase sample stream and a quadrature sample stream which together characterize a data signal in an IQ plane. The process includes generating a polar amplitude sample stream and a polar phase sample stream. The process includes generating an up-sampled polar amplitude sample stream by (i) identifying an origin crossing of the data signal in the IQ plane, (ii) responsively adjusting an inversion trigger, (iii) selectively applying an inversion to the polar amplitude sample stream based on the inversion trigger, (iv) interpolating the selectively inverted polar amplitude sample stream, and (v) removing the inversion from the interpolated selectively inverted polar amplitude sample stream. The process includes modulating a carrier signal using the up-sampled polar amplitude stream and the polar phase sample stream.

摘要： In one embodiment, it is proposed a method for obtaining at least one sub-aperture image being associated with one view, from raw light field data corresponding to recorded data by an array of pixels sensors positioned behind an array of micro-lenses in a light field camera, each of said pixel sensor recording a linear mixing of up to four different views. The method is remarkable in that it comprises applying a signal separation process on said raw data by using an inverse of a mixing matrix A, said mixing matrix comprising coefficients that convey weighting information of said up to four different views recorded by a pixel sensor.

摘要： A method for decoding a picture block is disclosed. The decoding method comprises: decoding decoded data, and information for identifying a reconstructed reference picture in a decoder picture buffer; reconstructing another reference picture from the identified reconstructed reference picture identified by the information and from the decoded data; replacing in the decoder picture buffer the reconstructed reference picture identified by the information with the another reference picture; and reconstructing the picture block from the another reference picture.
