Abstract

The invention is based on the observation that, considering the pedalling movement, the power developed by a cyclist takes the form of a permanent sine curve with a frequency that is double the pedalling frequency. This cyclic power variation results in a small oscillation of the speed of the cyclist, the amplitude of which can be observed through GNSS phase measurements which are more precise by an order of magnitude. A first aspect of the invention relates to a method for determining the pedalling cadence of a cyclist (10) on a cycle (12), wherein the pedalling cadence is extracted from an oscillation of GNSS signal phase measurements (16) taken on the cycle (12) via a GNSS receiver (14) or an oscillation of measurements calculated on the basis of the phase measurements.

Method and device to decode a GNSS signal in a GNSS receiver (300) comprising a channel decoder (134), wherein the GNSS receiver is configured to: - determine parameters relative to a statistical propagation channel model (301, 302, 303), the statistical propagation channel model being a Prieto channel model or a Perez-Fontan channel model, - compute a statistical channel attenuation from said statistical propagation channel model (310) using the parameters, - compute LLRs from a detection function (333) adapted to the statistical propagation channel model using the computed statistical channel attenuation, and - use the said LLRs to feed the channel decoder.

Abstract

The invention concerns a method and a device for digital image restoration. The digital image to be restored comes from an initial image acquired by an image acquisition device having an associated acquisition instrumental noise. The method comprises the following steps: —obtaining (30) an intermediate digital image with restoration of the acquisition instrumental noise, —denoising (32) the intermediate digital image in order to obtain a denoised intermediate digital image, —deconvolution (34) of the denoised digital image in order to obtain a restored digital image.

Abstract

The invention relates to a method for designing a plan for acquiring zones to be implemented by a space system comprising at least one satellite for several users, the method comprising the steps according to which a processor, proceeding from an initial acquisition plan, optionally comprising at least one acquisition Ai having a value v_i: a) receives a candidate acquisition request A_candidate associated with a value v_candidate, the candidate acquisition request having been issued by a user (Ui, Uj); b) determines a candidate plan P_candidate wherein the candidate acquisition request is included the initial plan; and if obtaining the candidate plan requires a deletion of at least one acquisition request from the initial plan, the method comprising a step of c) determining the sum of the values ​​v_i of the acquisition requests from the initial plan that are not included in the candidate plan, the inclusion of the candidate acquisition request being authorised as soon as the the sum is lower than the value v_candidate associated with the candidate acquisition request, wherein the candidate plan is the acquisition plan and at least one acquisition request, which is incompatible with the candidate plan, has been deleted.

Abstract

The invention relates to a device for assembling a first part on a second part (30), said device comprising: at least two jaws (2, 6), said jaws being supported by the first part, such that the jaws can be placed in a closed position, in which the jaws (2, 6) engage with a portion of the second part so as to prevent a separation, in at least one direction and in at least one sense, of said portion of the second part relative to the jaws, and can be placed in an open position, in which the jaws allow separation of said portion, a device (25) for retaining the jaws in the closed position adapted to be able to be broken by melting, characterised in that it comprises a resilient return device adapted to be able to resiliently return said jaws to the open position.

Abstract

The present invention generally relates to Global Navigation Satellite System (GNSS) positioning techniques. More particularly, it relates to a method to improve the time required to compute a position measurement in a GNSS receiver, and the time required to make this position measurement accurate. The method comprises computing a snapshot PVT (Position Velocity and Time) measurement, and use it to reduce the time required to acquire new signals to compute a conventional PVT measurement. It also relates to a receiver implementing the method.
