Patent EP-4279940-A1 (EP)
Inventor: ZELUDEVICIUS JULIJANAS
IPC: G01S3/783
Filed: 2023-01-17
Abstract: The invention relates to the fields of optical technologies and telecommunication technologies, and is dedicated to determination of the direction of optical beam in free-space optical communication systems. The invention is based on the property of interference optical filters (IOF), that transmittance and reflectance of such filters, for a beam with given optical spectrum, depends on the angle of the beam with respect to IOF surface normal. According to the proposed method, at least one IOF is used, which is rotated by defined angle with respect to the optical axis of the detection device. In the implementation of the detection device with one IOF (4), two optical power detectors (6, 7) are used, which measure optical power of the beam reflected from the IOF (1') and transmitted through the IOF (1"). Based on these measurements, the angle of the beam, with respect to the optical axis (5) of the device, is determined in one plane. To determine beam angle in another (perpendicular) plane, second beam angle detection device is used, which has IOF rotated in the perpendicular plane. After determining beam angles in both mutually perpendicular planes, full information regarding beam direction with respect of the optical axis of the system is acquired.

IPC: H04L9/32
Filed: 2019-03-18
Abstract: The invention relates to efficient zero knowledge verification of composite statements that involve both arithmetic circuit satisfiability and dependent statements about the validity of public keys (key-statement proofs) simultaneously. The method enables a prover to prove this particular statement in zero-knowledge.More specifically, the invention relates to a computer-implemented method for enabling zero-knowledge proof or verification of a statement (S) in which a prover proves to a verifier that a statement is true while keeping a witness (W) to the statement a secret. The invention also relates to the reciprocal method employed by a verifier who verifies the proof.The method includes the prover sending to the verifier a statement (S) having an arithmetic circuit with m gates and n wires configured to implement a function circuit and determine whether for a given function circuit output (h) and an elliptic curve point (P), the function circuit input (s) to a wire of the function circuit is equal to the corresponding elliptic curve point multiplier (s). The prover also sends individual wire commitments and/or a batched commitment for wires of the circuit, an input for a wire in the arithmetic circuit; and a function circuit output (h). The prover receives from the verifier a challenge value (x) and responding with an opening or additionally sends a proving key (PrK) to the verifier. The statement and the data enables the verifier to determine that the circuit is satisfied and calculate the elliptic curve point (P) and validate the statement, thus determining that the prover holds the witness (W) to the statement.

Abstract: A method and system are disclosed for performing a render using a graphics processing unit that implements a tile-based graphics pipeline where a rendering space is sub-divided into tiles. Primitives are received that were processed by a geometry processing stage of the graphics pipeline and these are grouped into one or more sets, and a primitive block generated from each set. Primitive block data is stored characterising the content of the one or more primitive blocks. It is determined which tile each of the primitives are located in, and for at least one selected tile a per-tile primitive block list is stored indicating which of the one or more primitive blocks contain primitives located in that tile. It is determined whether the output of a previous render for the selected tile(s) can be used as an output for the render based on the per-tile primitive block list and the primitive block data for the primitive blocks indicated therein, and corresponding data from the previous render.

Abstract: Positioning apparatus enabling an article such as, for example, a wafer (15) to be subjected to a photo-lithographic exposure, to be positioned accurately, for example in relation to an exposure mask (12). The article rests in frictional engagement on a support (22) coupled to piezoelectric transducers (17). The article may be moved through very small distances by applying suitable DC voltages to the piezoelectric transducers. For greater movements an asymmetric waveform may be applied to the transducers, causing the article to move with a jogging motion through much greater distances. The asymmetric waveform may be obtained, for example, by charging and discharging the capacity of the transducers through resistors of suitable value, or by applying a full wave rectified AC voltage to them. Four transducers may be used to enable the article to be moved in either of two mutually perpendicular directions or rotated about an axis (Figure 4). The supports (22) may be tubular and means (26, 27) may be provided for applying vacuum through them to increase the pressure of frictional engagement.

Abstract: La présente invention concerne le domaine des circuits intégrés à semi-conducteurs et plus particulièrement un procédé de caractérisation de la teneur en oxygène de barreaux semi-conducteurs, tirés selon la méthode de Czochralski. Ce procédé est le suivant: 1- découper une portion voisine d'une extrémité du barreau stabilisé et mesurer sa résistivité, 2- recuire cette portion à une température comprise entre 600°C et 900°C (pratiquement entre 650 et 850°C) pendant un temps suffisant (pratiquement entre 1 et 6 heures) dans une atmosphère d'azote, 3- décaper chimiquement et mesurer l'incrément de résistivité pour en déduire la concentration initiale en oxygène du barreau. Ces étapes peuvent être recommencées pour d'autres portions adjacentes du barreau jusqu'à ce que l'incrément de résistivité désiré selon les applications soit atteint. Par exemple pour les tranches destinées aux lignes de produits unipolaires (MOSFET), la teneur en oxygéne doit être >=30 ppmA. On procèdera de cette façon avec un recuit à 750°C pendant 6 heures à partir de la queue du barreau jusqu'à ce que l'incrément de résistivité mesuré indique qu'il y a eu effectivement une génération sensible de donneurs ND. La figure indique qu'à partir de 30 ppmA (pour ces conditions de recuit) la génération de donneurs est supérieure à 1.10¹<4> donneurs/cm³. Ce chiffre correspond par exemple à 3Ω.cm pour un barreau de silicium de type P de 19Ω.cm.
