Patent CA-2038121-A1 (CA)
Inventor: SCHRODI KARL
IPC: H04L12/56
Filed: 1991-03-12
Abstract: Starting point: The sequence is known of a copying switching matrix, a distribution switching matrix and a destination switching matrix on the one hand, and on the other hand a switching matrix in which copying can be carried out in every stage. 
<??>Technical problem: Real operation is a mixture of point-to-point connections, point-to-multipoint connections with few branches and point-to-multipoint connections with many branches. The overall traffic and its individual constituent parts are constantly changing. The known structures are optimised in each case for one specific traffic type in one direction only. 
<??>Fundamental concept: The switching elements of a switching matrix which is optimised for point-to-point connections contain the additional facility for copying a small number of input signals for any number of outputs, whereby a very large number of copies can be achieved overall for a very small number of input signals. This switching matrix is supplemented by a copying switching matrix, which serves solely to produce in each case a limited number of copies for a large number of input signals, which are then switched in the (main) switching matrix as point-to-point connections. 
<??>Solution: Point-to-point connections are operated as "connectionless connections" by means of automatic switching element control. It is ensured that these connections act outwardly as virtual connections. Point-to-multipoint connections are also operated in the main switching matrix as virtual connections (connection-oriented) by means of connection tables. 
<??>Advantage:Interference-free rearrangement of existing virtual connections possible. Very even utilisation of the (main) switching matrix as a whole. 
<??>Disadvantage: Switching elements with two different addressing facilities required.

Title: Souvenir vacation photo album
Inventor: SIMPSON LEONIE A
IPC: B42F5/00
Filed: 1991-05-31
Abstract: ABSTRACT The  idea  came  about  after several vacation where  the  inventor  took photographs of various attractions, events and activities of a particular place,  got  the photographs developed and kept them in envelopes  and/or bags instead of a central place where they can be retrieved easily. It  was thought that if photographs were taken on a particular  vacation, eg.   one to Jamaica, Barbados or Toronto then there should be one  photo album  with  the Jamaica photographs, one with the Barbados  photographs, and one with the Toronto photographs on a bookshelf or photo album shelf, i.e. three  separate  albums on the shelf.  With  the  albums  properly marked  they could be taken off without any trouble and families, friends or  individuals  could  look  back at these photographs  and  relive  the experience,  especially if an individual, say a loved one is  no  longer around. Strangers  to  an  island  or  state  are not  fully  aware  of  all  the interesting  places,  activities  and events that could be enjoyed  on  a visit,  therefore  it was thought that a list of such places,  activities and events would prove useful.  Although the list will not give the exact location  within the state or island of the attraction, nor say where the activities  and  events can be enjoyed, the owner of the album on  seeing that  there  are attractions, activities and events to be enjoyed,  will either  refer  to any tourist guide he or she might have, or  check  with their  hotel, guest house or wherever they might be staying.  Alternately they  could check with the nearest tourist office or booth, or with  just about anyone who it is felt will say what the attractions, activities and events  are and where they can go to enjoy them.  On the other hand  they might  have already visited that particular attraction or partook in that particular  activity or event and would use the list as a check point  to see  that  they  have fully explored all that there is available  on  the vacation. A  visitor to the Caribbean might not be aware of the fact that he or she could  go bowling, horseback riding or bird watching as these  activities are  not as popular in the Caribbean as say swimming of diving, the  list will be a guide to the vacationer on what can be done on the vacation. Most  if  not  all places of interest, activities and  events  within  an island  or  state are photographed by vacationers, hence the need  for  a specialized album to store these photographs.
