Patent CA-2282054-A1 (CA)
Title: Coaxially configured omt-multiplexer assembly
Inventor: TATOMIR PAUL J
IPC: H01P1/213
Filed: 1999-08-30
Abstract: An ortho mode transducer (OMT)/multiplexer assembly (20) having a corrugated junction (41) and a coaxial dual mode waveguide resonator (53) disposed around a central cylindrical waveguide (23). The corrugated junction (41) diplexes signals, the higher frequencies passing through the central cylindrical waveguide (23) and the lower frequencies passing through the coaxial dual mode resonator (53). Apertures (62) in the dual mode resonator (53) couple to an exit port (86) and extract a first polarization from the lower frequencies passing through the dual mode resonator (53). The assembly may include a second aperture (65) in the dual mode resonator (53) for extracting a second polarization in a manner similar to the operation of the first aperture (62).

Title: File system primitive providing native file system support for remote storage
Inventor: MILLER THOMAS J
IPC: G06F12/00
Filed: 1998-06-03
Abstract: In order to decrease the overall cost of storing large amounts of data, systems have been developed that use a hierarchy of storage devices from fast local disks ( 118) to archival off-line storage (122). Such storage devices (118, 122) may be managed in a hierarchy where data that is accessed only infrequently can be moved to archival storage (122). The present invention relies on a tight integration of a hierarchical storage manager (110) into the I/O system so that remotely stored attributes (112) can be identified and tracked internally to the I/O system just like any other attributes.      Implementations of the present invention may relay on a layered driver model where lower level drivers (104) detect the existence of files with remotely stored attributes (112) and then transfer control for processing I/O requests involving files with remotely stored attributes (112) to higher level drivers (100). The higher level drivers (100) then assume control to finish processing the I/O request.

IPC: H04N7/16
Filed: 2000-08-22
Abstract: Transmitting to a user an advertisement when the user is initially establishing communication with an Internet provider via a digital switching system. A server within the digital switching system transmits the advertisement. This advertisement may take a multitude of forms including a multimedia message that includes sound and video. In addition, when the user transfers from one web site to another web site, a server within the digital switching system responds to this action by transmitting an advertisement to the user until the new web site responds.      The digital switching system may be a broadband hybrid optical cable digital switching system. In addition, the digital switching system may also be an all digital fiber system which provides optical fiber directly to the home or office of the user. The server in the digital switching network can send additional information if a customer indicates during the transmission of an advertisement that they wish additional information from the advertiser. The ability of an advertiser to pinpoint the recipients of their advertisements so precisely will make the capability extremely valuable for advertisers.
