Abstract: A device and a method for spectroscopic measurement of the spectrum of a light beam. The method includes detecting the dispersed light fluxes of the beam on an imaging device comprising a matrix of photodetectors with active columns, directing the imaging device so that one wavelength is allocated to a line of photodetectors, determining for each light flux the exposure time ?i necessary to measure a maximal intensity Imax and the sub-matrix Mi of photodetectors associated with the light fluxes, allocating to the sub-matrix Mi of photodetectors an exposure time ??i so that ??i is the largest integer divider of the total integration time T smaller than ?i, measuring and resetting, during the integration time T of said spectrum, at each time ??i, the corresponding sub-matrix Mi independently of the other sub-matrices Mj with j?i, and measuring the spectrum of the beam at the time T.

Abstract: The invention relates to a device and a method for spectroscopic measurement of the spectrum of a light beam. According to the method, one detects the dispersed light fluxes of said beam on an imaging device comprising a matrix of photodetectors (23) with active columns (11). According to the invention, said imaging device (10) is directed so that one wavelength is allocated to a line (27) of photodetectors (12). One determines for each light flux (i=1, 2, . . . , n) the exposure time ?i necessary to measure a maximal intensity Imax and the sub-matrix Mi (13, 24-26) of photodetectors (12) associated with said light fluxes. One allocates to the sub-matrix Mi (13, 24-26) of photodetectors an exposure time ?!i so that ??i is the largest integer divider of the total integration time T smaller than ?i. During the integration time T of said spectrum, one measures and one resets, at each time ??i with i=(1, 2, . . .

Abstract: A method of integrating wireless and wireline billing information in an integrated wireless-wireline system. Existing Automatic Measurement Accounting (AMA) capabilities resident in the Advanced Intelligent Network (AIN) Service Control Point (SCP) of the wireline section are leveraged, thereby avoiding development of an independent billing capability in the wireless section. Problems associated with the allocation and exchange of the wireless call identifier are avoided.

Abstract: An integrated wireless wireline system (IWWS) architecture without the requirement for dual-tone modulation frequency (DTMF) signaling to communicate a called party's number from the wireless section to the wireline section, thereby expediting call setup and making it more reliable.
