Patent CA-2226950-A1 (CA)
Inventor: LECLERC OLIVIER
IPC: H04B10/43
Filed: 1998-02-17
Abstract: L'invention concerne un système de transmission à fibre optique à signaux solitons et à multiplexage de longueur d'onde, dans lequel les différentes longueurs d'onde du multiplex sont choisies de sorte à assurer, sur un intervalle (Z R) donné, un glissement relatif entre les différents canaux sensiblement égal à un multiple du temps bit (1/B), et dans lequel, en au moins un point du système de transmission, les impulsions solitons des différents canaux présentent par rapport à une référence donnée un décalage temporel tel que, lors d'une modulation optique distribuée par une horloge introduite audit point, pour chaque canal, l'extremum du profil de phase intégré sur la longueur de modulation, coïncide avec le centre du temps bit. On peut dans un tel système procéder à une modulation optique distribuée de l'ensemble des canaux du multiplex par un signal sinusoïdal unique. Cette modulation peut être effectuée dans un miroir non linéaire en boucle, ou encore dans la fibre de transmission elle-même.

Title: Retractable receptacle for furniture
Inventor: MCCARTHY DAVID G
IPC: H02G3/00
Filed: 1998-04-28
Abstract: A  receptacle   for  coupling  electrical   equipment  and communications  equipment  to  electrical  and  communications transmission lines  is retractably mounted in an opening in a furniture unit, and in particular, the top surface of an office conference table.  The receptacle is vertically displaceable so that it is elevated above the top surface of the furniture unit in which it is mounted to provide access for coupling electrical equipment such as lap top computers, or communications equipment such as telephones and fax machines, which are supported on the top surface of the furniture unit.  When the equipment is coupled to the elevated receptacle unit,  the unit  is then displaced downwardly into the furniture such that the top surface of the receptacle unit is planar with the top surface of the furniture unit in its fully retracted position.  A gap defined between the outer surface of the top surface of the receptacle unit and the inner surface of the opening in the furniture unit permits wires and cables to extend through the gap and remain connected to the receptacle  unit  when  the  receptacle  unit  is  in  its  fully retracted position in the furniture unit.   The receptacle unit may be displaced into its elevated position to disconnect lines coupled to it or to connect additional lines.  In this manner, portable electrical and communications equipment can be supported or stored on furniture units,  such as conference tables,  and actuated when needed by coupling the equipment to the receptacle in the furniture unit.

Patent CA-2243282-A1 (CA)
Title: Bit sliced digital cross connect switching system controlled by port units
Inventor: BORTOLINI JAMES R
IPC: H04Q11/04
Filed: 1998-07-16
Abstract: A switching network having a plurality of independent switching groups with each switching group capable of switching one bit of each group of data from external data links through a telecommunication switching system and port units interfacing the data links directly control which of the switching groups will be active. This allows extra switching groups to be utilized as replacement switching groups should a switching group actively switching a bit of the incoming data be disabled. This increases the overall reliability of the telecommunication switching system since a failure of a port unit will only effect the external data link that is connected to that unit. In addition, this eliminates complicated and centralized control for the switching units which would be needed to inform the switching units which units should be active and the bit a given switching unit should be communicating.
