Patent CA-2233048-A1 (CA)
Inventor: CAMPAU JOHN A
IPC: B65G57/24
Filed: 1998-03-25
Abstract: Masonry blocks conveyed in side-facing-side relation toward a cubing station for assembling into multi-tiered stac3cs are fed to 2 prepositioning station where the blocks are separated into groups of three and the trailing two blocks in each group are reoriented 90° into a so-called tie pattern with the other block.  The two trailing blocks remain in parallel relation and extend lengthwisely in the direction of conveyance.  The tie-patterned groupings are fed to a patterning station where they are relatively repositioned as necessary into the arrangement predetermined by the particular tier pattern being assembled.  Once properly oriented, the block groups are transferred to the cubing station.

Title: Wide-area wireless distribution system
Inventor: GRAVES DAVID H
IPC: H04L49/111
Filed: 1997-06-13
Abstract: A low power, multi-cellular, broadband communication system for the unidirectional (i.e. broadcast), bi-directional and multi-directional transmission and reception of voice, video, audio, television and data signals is provided within the context of a point to multipoint network topology. The system incorporates modem, modulator and demodulator elements that operate over the complete licensed band of the operator. In addition, the microwave transmitter, receiver and transceiver elements also operate over the licensed band of the operator, thereby achieving a broadband microwave infrastructure coupled with a flexible modem (modulator, demodulator) architecture that allows flexible channelization at the systems level. The system may operate over two or more separate frequency allocations, such as a downstream frequency allocation at 24 GHz coupled with an upstream frequency allocation at 36 GHz. This is possible because the partition of cell-site receiving and transmitting functions and the use of subscriber antennas that do not have equivalent transmitter/receiver patterns. This allows for different numbers and different types of receiver or transmitter cell-sites to be implemented. The use of advanced subscriber antenna technology allows for primary and secondary cell-sites to be defined for specific subscribers, thus providing route diversity to combat rain attenuation and rain outage effects, which are the primary cause of outage within the large-area networks operating at frequencies above 10 GHz. The unique system design discussed below allows for route diversity to combat rain and multipath fading effects.

Title: Proximity-based registration in a communication system
Inventor: BAKER ALBERT D
IPC: H04M3/42
Filed: 1999-01-28
Abstract: The invention in an illustrative embodiment provides binding and bridging between a mobile terminal and other more complex terminals in a communication system.  The binding is based on a determination of the proximity of the mobile to the other terminal, such that the mobile registers to different complex system terminals as it moves between different cells of the system. In accordance with the invention, a proximity-based temporary association is established, in a memory of a system switch, between the mobile and at least one other system terminal. While the mobile is "registered" in this manner to the other terminal, the mobile user can request permission to utilize the functions of the other terminal in order to, for example, receive incoming calls or place outgoing calls. Other embodiments of the invention provide proximity-based registration which utilizes a beacon device carried by the user, such that the user automatically registers to different system terminals as he or she moves about within the system.
