Abstract: A system 100 and method for interconnecting a remote computer 102 and a computer service provider 104 via a telephonic switch 122 is provided. The telephonic switch 122 connects the remote computer 102 to the computer service provider 104 based on information received from the remote computer 102. An adult material circuit 126 in the telephonic switch 122 detects a request from the remote computer 102 to prohibit access to adult material available on the computer service provider 104. The request may be contained in automatic number identification information or dialed number identification service information. The telephonic switch 122 further comprises a caller prompting circuit 132 which prompts the remote computer 102 for instructions regarding whether to deny access to adult material. An advertising circuit 136 in the telephonic switch 122 stores advertisements, selects one of the advertisements based on theinformation received from the remote computer 102 and displays the selected advertisements on the remote computer 102. The telephonic switch 122 further comprises an audio circuit 140 for establishing voice communications between a subscriber associated with the remote computer 102 and an agent telephonic unit 142 associated with the telephonic switch 122. While voice communications are established between the subscriber and the agent telephonic unit 142, a data link circuit 141 maintains a data connection between the telephonic switch 122 and the computer service provider 104 such that data communications are substantially automatically reestablished upon completion of the voice communications.

Abstract: A subcarrier signal generator (30) includes a finite impulse response (FIR) filter (40) responsive to selected FIR coefficients from coefficient register (44). A first set of FIR coefficients represents an ideal subcarrier shape and center frequency. A calibration step performed by calibration device (34) monitors the resulting subcarrier signal and produces a new set of FIR coefficients corresponding generally to the ideal subcarrier signal shape and center frequency, but predistorted according to the complement of error detected in the actual subcarrier signal. By then loading the new set of FIR coefficients and operating the subcarrier generator (30), frequency-dependent distortions in the output stage of the subcarrier generator (30) cancel predistortion reflected in the new FIR coefficients. As a result, a high quality subcarrier signal results without use of expensive output stage devices in the subcarrier signal generator (30).

Abstract: Dans une zone où une tôle en alliage d'Al et une tôle d'acier se chevauchent, un flan circulaire fait d'une tôle d'acier est disposé de manière à chevaucher ladite tôle en alliage d'Al. Ces trois éléments sont ensuite comprimés par deux électrodes entre lesquelles on renvoie un courant de soudage. On assiste ainsi à la fusion de la partie de la tôle en alliage d'Al où passe le courant, ainsi qu'à la fusion de la zone avoisinant cette partie. La partie fondue est éliminée étant donné la déformation en expansion partielle du flan vers la tôle en alliage d'Al. La partie déformée en expansion est ensuite mise en butée contre la tôle d'acier, ces dernières étant enfin soudées par résistance.

Abstract: Provided are automated methods for distinguishing and differentiating cells in a whole blood sample. In one of the methods, a whole blood sample is provided. One or more tests to be performed on the whole blood sample is selected. The tests to be performed on the whole blood sample are correlated. A volume of the whole blood sample is aspirated into an automated instrument system which automatically performs conventional hematology analysis and fluorescent cytometry analysis on the whole blood sample. A first aliquot of the whole blood sample is dispensed into at least one sample receiving vessel. The first aliquot of the whole blood sample is mixed with a fluorescent reagent. The first aliquot of the whole blood sample mixed with fluorescent reagent is diluted and transported through a flow transducer system. The flow transducer system detects multi-angle light scatter and fluorescence from the first aliquot of the whole blood sample mixed with fluorescent reagent and counts and differentiates platelets or platelet clumps or both in the sample. Detecting and differentiation data for the one or more tests performed on the whole blood sample are stored.  Results of the one or more tests performed on the whole blood sample are reported in a quantitative manner if so requested. The instrument system automatically performs all method steps without physically separating cells from the whole blood sample or an aliquot of the sample and results of a conventional hematology analysis may be utilized in at least reporting of results of the fluorescent cytometry testing.
