Abstract: Methods, systems, apparatuses, and computer-readable storage mediums described herein are configured to transfer call context between different call center systems. For example, a first call center system that establishes a communication session between a user and an agent of the first system provides context determined during the session to a call context service. The service stores the context and provides it to other requesting call center systems. For instance, during a call transfer to an agent of a second system, the first system requests the service to provide a transfer number of the second system to which the user is to be transferred. The service determines the transfer number and provides it to the first system. The first system performs the call transfer using the number. After the transfer is complete, the second system provides a request for the context, and the service provides the context to the second system.

Abstract: A method for locating at least one target, in an electromagnetically absorbent environment, includes: emitting at least one electromagnetic excitation signal from a source; receiving, by an acoustic sensor, an acoustic signal from emission of the excitation signal; detecting, in the received acoustic signal, a first time of receipt of a first response to the excitation signal from an acoustic disturbance caused by electromagnetic heterogeneity of the target in the environment; estimating a first distance between the target and the acoustic sensor using the first time of receipt; detecting, in the same received acoustic signal, a second time of receipt of a second response to the excitation signal from an acoustic disturbance caused by acoustic heterogeneity of the target in the environment; estimating a second distance between the source and target using the second time of receipt; obtaining a location of the target from the first and second estimated distances.

Abstract: The invention relates to a method of localising a fluorophore (22) in a scattering medium (20), by means of a radiation source (8, 10) suited to emitting an excitation radiation of this fluorophore and detection means (4, 12) suited to measuring a fluorescence signal (?fluo) emitted by this fluorophore (22) comprising: a) for at least 3 different pairs of positions of the radiation source and detection means, an excitation by a radiation coming from the radiation source (8), and a detection by means (4) of detecting the fluorescence signal emitted by this fluorophore after this excitation, b) for each of these pairs, the identification of a surface on which the fluorophore is situated, or a volume comprising this surface and in which the fluorophore is situated, c) an estimation of the localisation of the fluorophore in its surrounding medium, by calculation of the intersection of the three surfaces, or if necessary a volume around this intersection.

Abstract: A device and method for processing fluorescence signals emitted after excitation by radiation coming from a radiation source, by at least one fluorophore with a lifetime ? in a surrounding medium, which signals are detected by detection means, and which method includes the calculation, on the basis of detected fluorescence signals, of values of a variable, independent of ?, of the position or the distribution of fluorophore in said medium.

Abstract: The method enables a non-homogeneous diffusing object to be examined by illuminating the object with a continuous light by means of a light source. It previously comprises reconstruction of the three-dimensional spatial mapping of an attenuation variable representative of the diffusion and absorption non-homogeneities of the object, by resolving a diffusion equation ?2F({right arrow over (r)}S, {right arrow over (r)})?k?2({right arrow over (r)})F({right arrow over (r)}S, {right arrow over (r)})=AS?({right arrow over (r)}?{right arrow over (r)}S). In the diffusion equation, AS is a constant, {right arrow over (r)} the spatial coordinate of any point of the mesh of a volume at least partially containing the object, and {right arrow over (r)}S the spatial coordinate of the light source. The transfer functions of an equation used for reconstructing the distribution of fluorophores integrate the attenuation variable reconstituted in this way.

Abstract: The method enables the distribution of fluorescent elements in a diffusing medium having substantially a finite cylindrical shape to be reconstructed. The method comprises formulation of a plurality of first energy transfer functions respectively representative of the energy transfer between the punctual excitation light source and the fluorescent elements and formulation of a plurality of second energy transfer functions respectively representative of the energy transfer between the fluorescent elements and the detector. The first transfer functions and the second transfer functions can thus be Green functions solving the diffusion equation and corresponding to a finite cylindrical volume, the Green functions being expressed as a function of the modified Bessel functions.
