Patent CA-2302365-A1 (CA)
Title: System for database creation, maintenance and access using event marking and two-dimensional partioning
Inventor: MOULIN ALEXANDER
IPC: G06F17/30
Filed: 1999-07-26
Abstract: A system and method that reduces access, backup, restore and processing time required by partitioning data in a database into two dimensions. The first dimension is by event processing date and the second dimension is by partition group. Once partitioned in two dimensions the data is stored in two-dimensional partitions in the form of rolling tables including an event marker. This partitioning and marking is done upon receipt of data which eliminates the need for further processing to efficiently store data. This partitioning and marking further reduces the size of data blocks that need to be handled when backing up or restoring data, deleting data, and retrieving data. Thus, extremely large volumes of data can be handled in an efficient manner.
Patent CA-2304530-A1 (CA)
Title: Method and device for emitting a time signal
Inventor: SCHAFER WOLFGANG
IPC: G04R20/02
Filed: 1998-09-17
Abstract: The invention relates to a method and device for the transmission of a time signal (14) which can be received almost world-wide. Said time signal with suitable receivers (8) is used for automatically setting clocks (9) to the local time. To this end, the invention uses a time signal transmitter (6) on board a low-flying space station or satellite (3) in an orbit with a high or large inclination during which almost the entire surface of the earth is flown over in the course of time. Due to the low altitude, a sufficiently high received field strength can be generated on the ground despite low transmitting power so that reception by a wristwatch is also possible. Said transmitting power does not disturb other satellites. The time signal transmitter (6) not only transmits the actual time but also additional data concerning the instantaneous position, flying direction and future radio contact make times thereof. The surface of the earth is divided into numbered zones (17) enabling the receiving clock (9) to determine the local time from the transmitted data without a large calculation effort.
