Inventor: CORRIVEAU MICHEL
IPC: H04W4/14
Filed: 1998-09-29
Abstract: L'invention concerne un procédé de traitement de messages SMS dans un réseau de radiotélécommunications lorsqu'une entité message court (MS-SME) (31) basée sur une station mobile d'origine envoie un message d'origine SMS (35) en fonctionnant dans un premier centre de commutation mobile (MSC) (32) puis passe à un second MSC (33) avant que le MS-SME ne reçoive un message accusé réception SMS (43). Ce procédé consiste d'abord à introduire un paramètre R_Transaction ID dans le message d'origine SMS (35) envoyé par le canal de trafic numérique (DTC) du MS-SME d'origine au premier MSC. Si le MS-SME revient à un MSC d'ancrage (33), un paramètre SMS_Transaction ID (SMSTID) (37) est contenu dans un message de demande de renvoi ANSI-41 SMS (SMDBACK) (36) envoyé du premier MSC au MSC d'ancrage. Le paramètre SMSTID utilise les informations du paramètre R_Transaction ID pour permettre au MS-SME de comparer un message accusé réception SMS au message d'origine SME. Si le MS-SME passe à un nouveau MSC de desserte (51), le paramètre SMSTID est placé dans un message de demande SMS de délivrance d'accusé réception point-à-point (57), et envoyé du MSC d'ancrage (33) au nouveau MSC de desserte (57). Les informations du paramètre SMSTID sont utilisées par le second MSC pour envoyer un message accusé réception (60) au MS-SME d'origine.

Abstract: There is disclosed a trash compaction apparatus, specifically a waste paper baler, incorporating an improvement in the controls for the apparatus whereby proper identification from a proposed operator is required to start a compaction operation. In particular, the compaction apparatus has associated therewith a magnetic stripe card reader and a computer. In the computer memory, data is stored which may be compared with data read by the card reader from a would-be operator of the apparatus to determine if such person is an authorized operator. Input-output means are provided for inputting the data for the authorized operator ID function. A calendar and a clock in the computer enables a log to be created in computer memory with date, time and identification data for each attempted operation of the apparatus. The computer calendar routine can also optionally determine if a would-be operator has attained an age required for safe and legal apparatus operation. The apparatus remains accessible for deposit of waste material while preventing unauthorized starting of compaction operations. An optional keypad may be included in the apparatus to provide additional or alternative means for entering data for validation of authorization of an operator.

Abstract: Modulator and demodulator for spread spectrum systems. They can process two data channels at nominal rate or one high speed channel demultiplexed in two. In the modulator one PN sequence generator (306) generates two PN sequences provided to a switch (308). Each channel is demultiplexed (304), one output controls which PN sequence is provided by the switch, the other is modulo-2 added (310) to the chosen PN sequence. The demodulator includes a PN generator providing replicas of the two PN sequences. Each subchannel is multiplied by one of the PN sequences. A decision circuit chooses the subchannel with the largest integrator result magnitude and provides a control signal to a multiplexor. A switch outputs data bit from subchannel chosen. The multiplexor combines the switch output and the control signal.
