Title: Procede et dispositif de selection dynamique de la longueur des communications par impulsions de stations mobiles sur une voie de commande de retour numerique
Inventor: WARD TORBJORN
IPC: H04L1/00
Filed: 1997-02-18
Granted: 2005-05-17
Abstract: Dans un système à accès multiple par répartition dans le temps (ARMT), les erreurs de synchronisation sur les intervalles de récurrence concernant la réception des communications par impulsions de station mobile transmises sur la voie numérique de commande de retour sont observées par la station de base réceptrice (14). Une fonction de densité de probabilités (62) est alors élaborée par la station de base pour traduire le nombre d'instances de chacune des longueurs déterminées des erreurs de synchronisation sur le intervalles de récurrence constatées sur un laps de temps déterminé. Cette fonction de densité de probabilités est ensuite traitée pour identifier le pourcentage de communications par impulsions au cours de ce laps de temps qui dépasse (76) un seuil d'erreurs de synchronisation (64). Si ce pourcentage dépasse un pourcentage donné, un mode opératoire (70) de communication par impulsions de longueur abrégée est ordonné par la station de base à toutes les stations mobiles fonctionnant dans la cellule. Dans le cas contraire, le mode opératoire (72) de communication par impulsions de longueur classique est ordonné par la station de base. La mesure des erreurs de synchronisation des intervalles de récurrence est continuellement traitée pour réaliser un contrôle dynamique sur la longueur spécifique des communications par impulsions de la station mobile.

Title: Automatic wireless alerting on an automatic call distribution center
Inventor: HARDOUIN LARRY J
IPC: H04M3/42
Filed: 1999-02-09
Granted: 2002-08-13
Abstract: Allowing the alerting of supervisors and off duty agents to conditions on a split of an ACD system via wireless terminals. The conditions under which the wireless alerting will be performed are programmed by the owner of the ACD system rather than the manufacturer. The ACD center is connected to a wireless switching system via a primary rate ISDN interface (PRI) link. The ACD system considers the wireless switching system as another ACD system and utilizes the look ahead interflow operation to communicate information to the wireless switching system concerning the condition of a split. This is done by the ACD placing informational telecommunication calls to pseudo telecommunication numbers via the PRI link to the wireless switching system. The wireless switching system is responsive to each of these pseudo numbers to interpret the pseudo number as to the wireless terminal that should be contacted and an alphanumeric message that is to be displayed on that wireless terminal. The alphanumeric message defines the condition of the split to the supervisor or off duty agents of the split. The wireless switching system may be a wireless telephone system or a paging system. The wireless terminals may be wireless telephones or pagers.

Abstract: A damped mechanical joint assembly comprises two damping members, a joint body positioned therebetween and rotatable relative thereto; and a retainer for maintaining engagement of the damping members with opposite damping surfaces of the joint body. The joint body is provided with a plurality of damping cylinders positioned around the joint rotation axis in a uniformly angularly spaced circular pattern, and each damping cylinder comprises a pair of piston chambers, each opening onto opposite damping surfaces, and a constricted passage connecting the piston chambers.  Each of the piston chambers is provided with a piston assembly slidably positioned therein, and each damping cylinder is filled with fluid between the piston assemblies. Each damping member is provided with a circular groove comprising a plurality of uniformly angularly spaced ramped depressions separated by groove barriers. The number of damping cylinders preferably differs from the number of depressions by at least two. The fluid in the damping cylinders urges each piston assembly into engagement with the groove of the corresponding damping member, and the damping members are positioned so that when a piston assembly is located within a ramped depression of the groove of one damping member, the corresponding piston assembly is located at a groove barrier of the groove of the other damping member, thereby resulting in reciprocating motion of the piston assemblies and concomitant flow of the fluid though the constricted passage of the damping cylinders as the joint body rotates relative to the damping members. Viscous resistance to flow of the fluid through the constricted passage as the joint body rotates causes the piston assembly to be urged more strongly into engagement with one of the ramped depressions, thereby producing a damping torque opposing rotation of the joint body, the damping torque increasing with increasing angular velocity of the joint body.
