Abstract: A scleral lens that includes a cover part suitable for covering the pupil, the iris and, at least partially, the sclera of an eye of an individual. The cover part includes a transparent central portion. At least one electronic component is encapsulated in a portion of the cover part. A lens in which the form and/or the dimensions of the cover part are configured, at least locally, as a function of the arrangement of the electronic component or components and, if appropriate, of the non-axis symmetrical form of the eye, such that the pupil is totally visible through the transparent central portion of the cover part, when the lens is worn by the eye.

Abstract: The receiver includes a sampler designed to provide one or more samples (yn) per received symbol, the symbols belonging to a predefined alphabet; an equalizer designed to compute, for each received symbol, an estimate (zn) of this symbol based on a linear combination (y′n) of the samples (yn) for this symbol; and a decision module designed to determine the symbol of the alphabet closest to the estimate (zn) as detected symbol. The alphabet exhibits a decentering such that the transmitted symbols have a non-zero predefined expectation, and the equalizer is designed to add a non-zero scalar component (θ) to the linear combination (y′n) in order to compensate at least partially for the decentering.

Abstract: On the downlink, a mobile radio signal transmitted by a base station and a television signal may be received over the downlink by an external television aerial located on a building roof. After reception, these signals may be transmitted via a wired communication link to a processing module located in a confined space in which the terminal is located. The mobile radio signal may be extracted, amplified and sent by the processing module so as to be received by the terminal. On the downlink, the terminal may transmit a mobile radio signal to a base station. Alternatively, the terminal may transmit a radiofrequency signal received by the processing module which amplifies it and transmits it to a base station, with or without frequency transposition, and with or without format conversion.

Abstract: A priority-resource-limited CoMP scheme is proposed based on a coordination priority index of users which comes into play to perform cooperation set selection and resource allocation in small cell networks. The CoMP control unit (CCU) configures and then transmits to the donor (serving) Transmission/Reception Point (TRP) the coordination priority index which is determined as a function of the required Bit Rate for that specific User Equipment and the SINR or the CQI. The donor Transmission/Reception Point (TRP) then transmits the coordination priority indexes sent by the CCU to the corresponding User Equipment (UE)s. The configuration of the coordination priority index allows the User Equipment to select a subset of Channel State Information reports or Channel State Information quantities to report so that the threshold index of the coordination priority is met.

Abstract: An optical transmitter for transmitting a vector of information symbols over an optical fiber transmission channel made of a multi-core fiber, optical signals carrying the vector of information symbols propagating along the multi-core fiber according to two or more cores, wherein the optical transmitter includes a precoder configured to determine a precoding matrix depending on one or more fiber parameters associated with the multi-core fiber and to precode the vector of information symbols by multiplying the vector of information symbols by the precoding matrix.

Abstract: An optical system for detecting and tracking the eye movements of an individual. The system includes a frame, intended to be worn on the face of the individual, that includes a plurality of illumination sources. The system includes at least one contact lens, intended to be worn by an eye of the individual facing the frame, in which are encapsulated: an autonomous integrated circuit, a plurality of photoreceptors and a wireless communication transmitter. Variation in a signal (e.g., voltage or current) delivered by the photoreceptors allows not only the closure of the eyelid but also eye movements to be detected.

Abstract: A method and system for assigning power to sub-bands in a multiple access communications system, where users are assigned iteratively to sub-bands, and at each iteration a provisional partial power budget is determined for the subset of sub-bands comprising the sub-bands to which users have been assigned in the present time slot and the sub-band under consideration in the sequence, where the fraction of the total available power determined as the provisional partial power budget corresponds to the fraction of the number of sub-bands in the subset from the total number of sub-bands to be assigned, and the provisional power allocation for the sub-band under consideration is obtained by performing a waterfilling distribution of the provisional partial power budget amongst the subset of the sub-bands, based on the channel gain of the users already assigned to sub-bands in the present time slot.

Abstract: The disclosure describes one or more embodiments of systems, methods, and non-transitory computer-readable media that modify vertex positions of a 3D-object mesh to align the vertices with discontinuities indicated by a sharpness map for a displacement map. For example, the disclosed systems access a sharpness map that encodes discontinuities of a displacement map to preserve sharp features. During sharp tessellation, for a given vertex of the 3D-object mesh, the disclosed systems iterate over neighboring vertices to search for a nearest intersection between one of the incident edges of the vertex and neighboring vertices and a discontinuity line from the sharpness map. Then, the vertex is moved within a threshold distance of the nearest discontinuity line intersection along the incident edge. The disclosed systems similarly reposition other vertices of the 3D-object mesh to generate a modified 3D-object mesh that includes vertices that align with discontinuities present in a displacement map.
